Sleep Improves Children’s Ability to Absorb Information and Learn

By Matthew D. Mingrone, M.D. of eOs Sleep

It has been common scientific knowledge for some time that when people sleep, our brains consolidate the information we subconsciously absorb during the day, and process it into explicit, conscious knowledge.

Both children and adults do this, but an interesting new study out of Germany shows that during sleep, children's brains convert subconsciously absorbed information—known as implicit learning—into active, useful knowledge even more effectively than adult brains do.
Implicit learning is typically considered subconscious learning; the acquisition of knowledge independent of conscious attempts to learn. For example, a child can say a sentence without understanding the rules of English grammar.

Explicit learning, on the other hand, is deliberate, conscious learning; the active and aware acquisition of skills and/or knowledge. Typically, explicit learning is accompanied by “meta-awareness,” a person can explain how they acquired the skill and/or knowledge.
When we sleep, implicit knowledge becomes explicit memory, making it easier for us to recall and use the information we have previously absorbed.

In a new study conducted by Dr. Ines Wilhelm of the University of Tübingen's Institute for Medical Psychology and Behavioral Neurobiology in Germany, and colleagues, the researchers studied 35 children between the ages of 8 and 11 years old, as well as 37 adults between 18 and 35.

For the test, the subjects were asked to press a sequence of buttons after they lit up. Half of the subjects did the test before sleep, the other half after sleep. They were then asked to recall the sequence of buttons/lights 10 to 12 hours later. Following a night of sleep or a day awake, the subjects’ memories were tested.

An article explaining the results of the study, entitled, “The sleeping child outplays the adult's capacity to convert implicit into explicit knowledge,” is published in the February 24, 2013 online edition of Nature Neuroscience.

The authors observed that after a night’s sleep, both age groups—8 to 11 and 18 to 35—remembered a larger sequence of buttons/lights than those who did not sleep. It also showed the children were better at it than the adults—almost all of the children could remember the sequence they had pressed perfectly, while adults experienced smaller gains.

Lead author Dr. Ines Wilhelm wrote, “In children, much more efficient explicit knowledge is generated during sleep from a previously learned implicit task. And the children’s extraordinary ability is linked with the large amount of deep sleep they get at night. The formation of explicit knowledge appears to be a very specific ability of childhood sleep, since children typically benefit as much or less than adults from sleep when it comes to other types of memory tasks.”

Children absorb massive amounts of information every day. They also generally sleep longer and deeper, and experience three times more slow-wave sleep and higher electrical activity in the brain during sleep than adults. This may help them “convert” the information they take in every day into knowledge they can recall and use. This is yet another important reason why parents should ensure their children are getting enough uninterrupted sleep every night.

Women with Sleep Apnea Show Higher Brain Damage, Anxiety than Men

An estimated 18 million Americans have obstructive sleep apnea (OSA), including one in four women over 65, according to the National Sleep Foundation.

And several recent studies have linked OSA to health disorders specifically in women. Sleep apnea has been linked to dementia in older women,  and another observational study found that women with untreated severe OSA are 3.5 times more likely to die from cardiovascular disease than women without OSA.

Here’s another reason for women to take sleep apnea seriously: A first-of-its-kind study out of the UCLA School of Nursing discovered that women with sleep apnea are more likely to suffer a higher degree of brain damage than men with sleep apnea.

What is obstructive sleep apnea? OSA is a disorder that occurs when a person's breathing is repeatedly interrupted during sleep, sometimes hundreds of times a night. During each obstruction, the oxygen level in the blood drops, which over time, causes myriad health problems. For people with sleep apnea, the combination of disturbed sleep and oxygen starvation may lead to hypertension, heart disease and mood and memory problems, among other disorders.

The new UCLA study

UCLA has been on the cutting edge of sleep apnea research. About 10 years ago, the same UCLA research team that conducted the new study was the first to show that men with OSA have damage to their brain cells.

For the latest multi-year study, entitled "Sex Differences in White Matter Alterations Accompanying Obstructive Sleep Apnea,” the researchers studied patients diagnosed with OSA at the UCLA Sleep Laboratory. They compared the nerve fibers in the patients' brains, known as “white matter,” to the nerve fibers of people without OSA or other sleep problems. The goal was to find the differences in brain damage, if any, between men and women with OSA.

Results of the study

The researchers found that women are actually more affected by sleep apnea than men. Additionally, women with OSA have more severe brain damage than men suffering from a similar condition. The women with sleep apnea also showed higher levels of depression and anxiety symptoms.

Specifically, the study found that women were impacted in the cingulum bundle and the anterior cingulate cortex areas in the front of the brain involved in decision-making and mood regulation.

Based on the results, chief investigator Paul Macey said, “Doctors should consider that OSA in women may be more problematic and therefore need earlier treatment in women than men.”

With the results of this study as a foundation, the next step is for the researchers to find out if treating sleep apnea can help the brain.

In a “chicken or egg” scenario, did the OSA cause the brain damage, or did the brain damage cause the OSA?  Or did the common conditions, such as depression, dementia or cardiovascular issues cause the brain damage, which in turn leads to sleep apnea?

The study and resulting questions are fascinating, and one thing is for sure: both men and women who are having trouble sleeping should get checked for obstructive sleep apnea and other sleep disorders.

Researchers estimate that up to 85 percent of people with severe sleep apnea have not been diagnosed yet.

Many times, sleep apnea can be misdiagnosed as chronic fatigue, insomnia, depression, or some other non-specific condition, so be specific about the symptoms you are experiencing.

Don't wait to get checked—it could save your life, or someone you love.

Can more sleep help ease pain? Yes, says new study!

Chalk another one up for the benefits of sleep. Researchers at the Sleep Disorders and Research Center at the Henry Ford Hospital in Detroit have found that getting more sleep improves daytime alertness and reduces pain sensitivity in healthy adults.

The study was led by Timothy A. Roehrs, Ph.D. of the Sleep Disorders and Research Center at the Henry Ford Hospital and supported by the Fund for Henry Ford Health System. Roehrs and his colleagues studied 18 pain-free, but mildly sleepy volunteers.

For the study, the participants were randomly assigned to four nights of either their normal amount of sleep, or extending their sleep time to 10 hours in bed per night. Their daytime sleepiness was measured on days one and four using the Multiple Sleep Latency Test (MSLT), a tool that measures how quickly a person falls asleep. Their pain sensitivity was also measured using finger withdrawal latency pain testing to a radiant heat stimulus.

The first study to prove sleep reduces pain.

The results of the study were published in the Dec. 1 issue of the journal Sleep. It is the first research of its kind to prove that extended sleep in mildly sleep-deprived adults can significantly reduce their sensitivity to pain.

The results showed that the extended sleep group—those who slept more than normal—slept 1.8 hours more per night than the normal sleep group. It also showed that they experienced less daytime sleepiness. This increase in sleep time during the four nights correlated to increased daytime alertness, as well as less sensitivity to pain.

Regarding the pain test, the extended sleep group showed a greater tolerance for pain/reduced pain sensitivity. The length of time before participants removed their finger from a radiant heat source increased by 25 percent. The researchers noted that this increase in “finger withdrawal latency” is greater than the effect found in a previous study where participants used 60 milligrams of codeine.

In their report, the researchers stated that the results, combined with data from previous research, suggest that increased pain sensitivity in sleepy individuals is the result of their underlying sleepiness.

Timothy Roehrs, PhD, the study’s principal investigator and lead author said, “The results suggest the importance of adequate sleep in various chronic pain conditions or in preparation for elective surgical procedures. We were surprised by the magnitude of the reduction in pain sensitivity, when compared to the reduction produced by taking codeine.”
Read the press release for the study, “Extended sleep reduces pain sensitivity.”

Lack of sleep and an increase in strokes.

Roehrs’ study adds to growing evidence that more regular, restorative sleep can help reduce the risk of health problems, and the opposite is true, as well.

Last June, the University of Alabama at Birmingham released the results of a study that regularly sleeping less than six hours a night significantly increases the risk of stroke symptoms in middle-age to older adults who are of normal weight and at low risk for obstructive sleep apnea (OSA). That’s worth repeating: Less than six hours of sleep per night increases the risk of strokes in adults of normal weight and not at risk for OSA.
It seems that under six hours of sleep per night is the critical variable, but why? Let’s take a look at the study. The University of Alabama researchers followed 5,666 people  for up to three years who had no history of strokes or stroke-like symptoms, transient ischemic attacks (when blood flow to the brain stops for a brief period causing stroke-like symptoms), or high risk for OSA at the start of the study.

For a period of three years, the researchers followed and studied the subjects’ first stroke symptoms, stroke risk factors, depression symptoms, demographic information and other various health behaviors. What they found was—after adjusting for body-mass index (BMI)—there was a strong association between daily sleep periods of less than six hours and a greater incidence of stroke symptoms for middle-age to older adults, even beyond other risk factors. Interestingly, the researchers did not find any link between short sleep periods and stroke symptoms in overweight and obese participants.

Still, the connection between short sleep and strokes is worthy of great attention from the medical community and general public. I agree with the Alabama study’s lead author, Megan Ruiter, PhD., who said, “The results of the Alabama study provide a strong argument for increasing physician and public awareness of the impact of sleep as a risk factor for stroke symptoms, especially among persons who appear to have few or no traditional risk factors for stroke.”

It looks like the medical community is taking this message to heart, no pun intended. Another study announced in late July is going on at the Alberta Health Services and the University of Calgary. There, Dr. Patrick Hanly of the university’s Hotchkiss Brain Institute is leading a study to learn more about the physiological connection between sleep apnea and stroke—specifically, the brain’s blood flow response in people with and without sleep apnea.

For the study, participants with sleep apnea stay overnight in the sleep laboratory at Calgary’s Foothills Medical Centre, where their breathing and cardiovascular responses are continuously monitored while they sleep. The next day, their brain blood flow response to reduced oxygen levels is assessed while they are awake. Then, the participants receive supplemental oxygen during sleep for two weeks, and are tested again to see if their cerebral defense mechanisms have improved. The researchers are also studying people without sleep apnea to see if their cerebral defense mechanisms function better than in those with sleep apnea. Hanly and team’s theory is that it is the lack of oxygen, or hypoxia, that people with sleep apnea experience during sleep that impairs the body’s normal defense mechanisms in the brain. A better understanding of this connection will lead to better prevention and treatment strategies.

I applaud the work of the Alabama and Calgary researchers. It’s time we all wake up to the health benefits of regular, restorative sleep

Is the quality of your sleep making you gain weight?

How many of us would like to lose a few pounds, but look for external ways—outside of our bodies—to lose weight?  Perhaps we should be looking more inward, not only at our personal diet and exercise levels, but the length and level, or phase, of our sleep.

Recently, I read an article in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology. In it, researchers from St. Luke's-Roosevelt Hospital and Columbia University in New York shed some light on the link between our length and phase of sleep, and hunger and weight gain.

The researchers investigated the effects of “sleep architecture” on hunger to determine whether specific stages of sleep—not just the duration of sleep—affect the appetite and food cravings in healthy adults.

What they found is compelling, and cause for further attention: the length of time of sleep, as well as the percentage of overall sleep in different sleep stages, are associated with decreased metabolic rate, increased hunger, and increased intake of calories, specifically from fat and carbohydrates.

For the study, head researcher Ari Shechter and his colleagues studied a random sample of 27 healthy adults between the ages of 30 and 45. The participants underwent two six-day periods of laboratory observation, during which they were slept different lengths of time.

During a "habitual sleep" phase, they were allowed to sleep for nine hours; in the "short sleep" phase, they were allowed just four hours of sleep. Each of the two sleep phase studies were separated by four weeks to make sure the participants fully recuperated, and the women were observed at the same phase of their menstrual cycle. The amount of time spent in each sleep phase—stage 1, stage 2, slow wave sleep (SWS), and REM sleep—was recorded.

For the first four days in both sleep phases, the participants ate meals to meet their energy requirements for weight maintenance. On day four, they rated their hunger and level of desire for different foods. On day five, their resting metabolic rate (RMR) was measured, and for the final two days of the sleep phase studies, the participants were allowed to select their own foods.

The researchers then compared the participants' sleep architectures in both the short sleep and habitual sleep conditions. They also analyzed the relationships between sleep architecture, resting metabolic rate, food intake and food desire ratings.

Shechter and his colleagues found that sleep duration is important, but sleep composition—the time and percentage of overall sleep spent in each stage—also plays an important role in the link between sleep and obesity.

Head researcher Shechter explained, “Any number of various factors like obstructive sleep apnea, certain drugs/medications, chronic exposure to short sleep duration, shift work, jet lag, and changes in the scheduling of the sleep episode, can affect sleep stage quantity and distribution. Our data may provide an explanation for the greater obesity prevalence observed within some of these conditions."

Read the full article, “Changes in Sleep Architecture Increase Hunger, Eating.”
The results of this study remind me of another study I blogged about not long ago on “social jetlag,” another reason for all of us to get more sleep.

Social jetlag is a modern syndrome caused by the discrepancy between our internal body clock and our social clock. And according to Professor Till Roenneberg, Ph.D. at the University of Munich’s Institute of Medical Psychology in Germany, that gap between how much sleep we need and how much we’re actually getting is contributing to our global weight gain and the growing worldwide obesity epidemic.

Each of us has a physiological clock, and that internal clock — also known as our circadian rhythm — is regulated by daylight and darkness to prompt us to go to sleep or wake up. We also have a social clock of things that make up our daily lives, such as our work schedules and social calendars.

The problem is, in our modern society of too-late work hours and too much time in front of computer screens, we are listening to our social clocks more than our physiological clocks, causing a greater sleep gap known as social jetlag. As a person’s circadian rhythm gets more out of whack, their physiological clock gets set later and later, keeping them awake into the night, and feeling chronically tired during the day.

In their study, Professor Roenneberg and his fellow researchers in Munich discovered that people with different weekday and weekend sleep schedules—i.e., those with more social jetlag — were three times more likely to be overweight. That is a significant increase worth repeating: Three times more likely to be overweight!

Furthermore, the body mass index (BMI) of the overweight participants tended to increase as the gap between their weekday and weekend sleep clocks widened.
I applaud the efforts of Roenneberg and his team for their work in particular, because they are bringing a public awareness of a growing syndrome that is affecting many people worldwide — not just shift workers or those with irregular work schedules.

So, why does social jetlag cause weight gain? One of the theories is that late hours encourage irregular meal times and late-night eating, when the body has more difficulty digesting and metabolizing food. That translates into body fat. Another is that chronically tired people are less likely to exercise and more likely to smoke and drink, further contributing to weight gain.

Whatever the causes, it is in all our personal best interests to become more aware of our own physiological clocks and get more restful sleep. Doing so can help us all maintain a healthy body weight, avoid many health problems, feel better and live happier, more productive lives.

So, now that you have this new knowledge about sleep, weight gain, I suggest you give yourself a wonderful personal gift: get more sleep, especially during the holiday season, when many people are overeating and busier than usual. Also spend more time outdoors and exercise. More and better sleep is one of the best gifts you can give yourself for the holidays.

Women, Wake Up: Sleep Apnea is Not Just a Male Disorder

Earlier this year, a particularly alarming statistic came out of Valme University Hospital in Seville, Spain, where researchers found that women with untreated severe OSA are three and a half times more likely to die from cardiovascular disease than women without OSA. (Read a summary of the study here.)

Since then, more research has been published showing high rates of sleep apnea in women,  as well as increasing links between OSA and age, obesity and hypertension.

In one new study published in August, researchers from Uppsala and Umeå University in Sweden analyzed 400 women between the ages of 20 and 70 years. They found that OSA was present in 50 percent of ALL the women participants aged 20 to 70 years.

They also found that 80 percent of women with hypertension and 84 percent of obese women suffered from sleep apnea. Of the obese women, 31 percent between age 55 and 70 had severe sleep apnea.

The alarming high percentages show that this should be a wake-up call to women.  Sleep apnea is not just a male disorder. Women—especially those with hypertension and/or obesity—need to wake up to the dangers of OSA and seek treatment if diagnosed with it.

Even Dr. Karl Franklin, lead author of the Swedish study, was surprised by the findings. He said, “We were very surprised to find such a high occurrence of sleep apnea in women, as it is traditionally thought of as a male disorder. These findings suggest that clinicians should be particularly aware of the association between sleep apnea and obesity and hypertension, in order to identify patients who could also be suffering from the sleeping disorder.

I agree wholeheartedly with Dr. Franklin, and add to his point that individuals, not just doctors, also need to be aware and speak up if they suspect they may have sleep apnea and related conditions. Read a summary of the study.

A few more recent studies showing OSA’s link to women’s health issues:

A study published in the September issue of the journal Obstetrics & Gynecology out of the University of South Florida found that babies born to obese women with OSA were more likely to be admitted to the neonatal intensive care unit than babies born to women without OSA. In addition, the women with OSA were more likely to develop a high blood pressure condition during pregnancy known as preeclampsia, and to deliver their babies by cesarean section.

Read the study, entitled, “Sleep apnea in obese pregnancy women linked to poor maternal and neonatal outcomes.”

In another study also published in September, sleep apnea in women has been linked to overactive bladder syndrome.

Researchers from the Hospital del Mar in Barcelona, Spain gave 72 women a questionnaire regarding their bladder control and four specific symptoms. According to the results, 62 of the women polled were diagnosed with obstructive sleep apnea (OSA). Further, the women with OSA scored higher on the questionnaire for the prevalence of bladder control symptoms, and the discomfort related with these symptoms.

More research is needed, but clearly, evidence is mounting showing the link between women and sleep apnea, and related disease and disorders. With one in four women over age 65 suffering from sleep apnea, according to the National Sleep Foundation, every woman who believes she is suffering from a sleep disorder-related condition should learn more and get checked out by a qualified sleep doctor. Many women are selfless caretakers, and will put their own worries or needs aside to take care of the needs of others. But don’t wait: Your health is the most important thing, and the healthier you are, the more productive you’ll be and the better you can care for your loved ones.

How do you know you may have obstructive sleep apnea? Some common symptoms include snoring, paused breathing during sleep and excessive sleepiness during the day. If you or someone you know is waking during the night gasping for air, that is a signal to seek diagnosis. Increased blood pressure is another sign you may have sleep apnea. For further study, read “Women and Sleep”  on the National Sleep Foundation website.

When you go for an exam, be specific with your doctor about the symptoms you are experiencing. While sleep apnea is more common in men, OSA increases in women after age 50. Many times, obstructive sleep apnea can be misdiagnosed in women as chronic fatigue, insomnia, depression, or some other non-specific condition. Also, some doctors still associate sleep apnea more with men than women, and are too quick to prescribe a medication, rather than do a full sleep disorder work up. Be  as clear and detailed as you can about your symptoms and what you are experiencing, and don’t wait —it could save your life.

The Link Between Sleep Apnea and Cancer—Evidence is Mounting

September is back to school month for many of our children — it’s also a good time for adults to learn about health issues, so here is some information to help you become educated about the health risks associated with untreated sleep apnea. Evidence is mounting: severe obstructive sleep apnea (OSA) may be linked to a higher risk of dying from cancer.

The results of three recent studies in Spain were presented in early September at the European Respiratory Society’s (ERS) Annual Congress in Vienna. The data presented by the Spanish researchers reinforces the results of previous studies which show similar links between severe OSA and cancer death. 

While scientists have yet to prove 100% that sleep apnea causes a higher risk of cancer death, more and more studies are showing the link. When obstructive sleep apnea occurs, a person’s airway becomes obstructed during sleep, blocking air flow and causing the person to wake suddenly, often gasping for air. This can happen hundreds of times a night, causing a person’s blood oxygen level to drop abnormally low.

Many researcher theorize that the lack of adequate oxygen supply, known as intermittent hypoxia, caused by OSA causes increased vascular growth and tumor growth because poor breathing fails to oxygenate the cells sufficiently.

Thankfully, people with sleep apnea can be treated using multiple methods. One of the most effective is continuous positive airway pressure (CPAP) therapy, which generates a stream of air to keep the upper airways open during sleep.

Let’s look at some recent sleep apnea and cancer studies out of Spain. Dr. Miguel Angel Martinez-Garcia from La Fe University Hospital in Valencia, Spain, and his fellow researchers studied more than 5,600 sleep apnea patients from seven different sleep clinics in Spain. The researchers measured the severity of a patient’s sleep apnea, based on the number of times during the night that a patient’s blood oxygen level dropped below 90 percent oxygen saturation.

The results of the study showed that people with sleep apnea who spent more than 14 percent of their sleep time with oxygen saturation levels below 90 percent not only had severe sleep apnea, but were approximately double the relative risk of dying due to cancer than people without sleep apnea. The researchers also found a significant increase in the relative risk of dying from cancer in people with less severe sleep apnea. This association was even higher in men and younger people.

Lead researcher Dr. Martinez-Garcia stated that the results do not mean unequivocally that sleep apnea causes cancer—it means the researchers found an association between the two disorders. However, the results of the experiment add to growing evidence that there is a clear link between sleep apnea and cancer mortality. 

Research from two other Spanish studies presented at the European Respiratory Society’s Annual Congress showed an increase in cancer incidence in humans, as well as an association between sleep apnea and the spread of cancer in mice.

The second study showed an increase in all types of cancer in people with severe sleep apnea, even when other factors such as age, sex and weight were taken into account. In a third study, Spanish researchers used mice to study the spread of melanoma skin cancer, and whether this was associated with sleep apnea.

The results showed that the spread of cancer was more abundant in mice that had experienced low levels of oxygen as in sleep apnea, than those who breathed normal air during the experiment.

According to the study’s lead author, Professor Ramon Farre from the University of Barcelona in Spain, the results of the mouse study strongly suggests a link between sleep apnea and the spread of cancer, and encourages further research to better understand the links between sleep apnea and cancer.

I agree with Professor Farre that these recent studies offer compelling evidence, and it is our responsibility in the medical and scientific communities to continue researching and testing to better understand the link between sleep apnea and cancer.

Heavy Technology Use linked to Fatigue, Stress and Depression in Young Adults

Modern technology is affecting our sleep. The artificial light from TV and computer screens affects melatonin production and throws off circadian rhythms, preventing deep, restorative sleep.

New research out of the University of Gothenburg, Sweden reinforces this fact, specifically relating to young adults. Doctoral student Sara Thomée and her colleagues at the University of Gothenburg's Sahlgrenska Academy conducted four studies to find out the effects of heavy computer and cell phone use on the sleep quality, stress levels, and general mental health of young adults.

For the study, Thomée and her team asked 4,100 young adults between age 20 and 24 to fill out questionnaires. They also interviewed 32 of them who were considered heavy information and communication technology (ICT) users. The researchers analyzed and compiled the data, and the results revealed that intensive use of cell phones and computers can be linked to an increase in stress, sleep disorders and depressive symptoms in young adults.

Some of the more specific findings are:

• Heavy cell phone use showed an increase in sleep disorders in men, and an increase in depressive symptoms in both men and women. 

• Those constantly accessible via cell phones were the most likely to report mental health issues.  

• Men who use computers intensively are more likely to develop sleeping problems.
• Regular, late night computer use is associated with sleep disorders, stress and depressive symptoms in both men and women.
• Frequently using a computer without breaks further increases the risk of stress, sleeping problems and depressive symptoms in women.
• A combination of both heavy computer use and heavy mobile use makes the associations even stronger.

So, what’s behind this link between technology use and negative health symptoms? The researchers have not yet fully determined why heavy technology users are more likely to have sleep disorders, higher stress and mental health issues, but one theory is that people with these symptoms are more likely to reach out and contact friends and family via technology.

I tend to think that the relationship between technology and stress, sleep disorders and depression has more to do with the overuse of technology in our society, especially among young people. If you’re a parent like I am, than you know first-hand how difficult it can be to get children to turn off the computer or put down their phone and stop texting so you can, just maybe, have a real conversation.

This is a growing and serious public health hazard that should be acknowledged and addressed by both the medical community and technology industry. It’s been scientifically proven that the light from TV and computer screens affects melatonin production and melanopsin stimulation, and throws off our circadian rhythms. This interrupts or prevents deep, restorative sleep, causing an increase in stress and depressive symptoms.

In the words of head researcher Sara Thomée, "Public health advice should therefore include information on the healthy use of this technology.” I couldn’t agree more. Just like alcohol ads, so should technology companies carry warnings on their products and in their advertisements. “Text responsibly.” “Don’t surf, then sleep.” You get the idea.

What can we, as individuals, do to protect our health from the negative impact of the ubiquitous technology in our society? Quite simply, turn it off, and get some good sleep. When you are on the computer for any length of time, take more frequent breaks, and impose limits on the amount of time you spend online. Trust me, the world will wait patiently for another Facebook post or text from you.

Remember, people need an average of seven to eight hours of restful sleep to fully take advantage of its restorative power and avoid daytime symptoms of fatigue. So turn off your TV and computer at least one hour before you go to sleep. Don’t sleep with your cell phone on and next to your bed. (Few things are more frustrating than being awakened in the middle of the night by an unimportant text message.)

Re-claim your bedroom for its intended purpose: restful sleep. Move the TV and computer out of the bedroom, or at the very least, don’t watch TV or work on the computer too close to bedtime. Stick to a bedtime routine. Get at least 7-8 hours of sleep every night. Try to go to sleep and wake up around the same time every day, even on weekends. Try to keep to within 20 minutes of the same time each morning and night.

Before bed, do activities that will promote sleepiness, such as a taking a warm bath, or reading a book or magazine. It also helps to maintain a cool temperature in your bedroom. A cool but comfortable temperature is ideal for sleep. Too warm and you will be fitful, too cold however can be uncomfortable and disturb your sleep.

Exercise regularly but not after the late afternoon. Even though exercise helps regulate sleep, rigorous exercise causes endorphins in the body to circulate which can have a stimulant effect, and keep you awake longer at night.

Stay away from caffeine at night. The effects of caffeine are different from person to person, and may last hours after your last cup of coffee, so make your last cup of coffee, regular tea or soda earlier in the day. Avoid alcohol and medicines that make you drowsy. Even if you think it is helping you fall asleep initially, alcohol and medicines that makes you drowsy may affect your sleep throughout the night.

And finally, if you feel that you are suffering from persistent sleep disorder, get checked out by a qualified sleep doctor. Regular, healthy sleep is one of the best things you can do for your mental and physical health.

Lack of Sleep is Stressing Us Out, New Study Says

Stress in our life is not only caused by what we do and our busy schedules—stress is also caused by what we don’t do, namely, not get enough sleep. A new study by researchers in England and the Netherlands have discovered that a severe lack of sleep creates a response in the immune system that is similar to the body’s immediate response when it experiences a stressful situation. Yes, even lack of sleep is stressing us out.

The study was a joint effort by the Department of Forensic Molecular Biology at the Erasmus MC University Medical Center in Rotterdam and the Centre for Chronobiology, Faculty of Health and Medical Sciences, University of Surrey, and the University of Surrey Clinical Research Centre in England.

So how did the researchers determine this? They compared the white blood cell counts of 15 healthy young men under both normal and severely sleep-deprived conditions.

In the first phase of the study, the men followed a strict schedule of eight hours of sleep per night every day for one week. They were also exposed to at least 15 minutes of outdoor light within the first 90 minutes of waking, and prohibited from using caffeine, alcohol or medication during the final three days of the first week.

The researchers required this in order to stabilize the participant’s circadian clocks and minimize sleep deprivation before the second phase of the study. The researchers then categorized and measured each participant’s white blood cells.

In the second phase of the study, the men stayed awake for 29 continual hours, and their white blood cells were again recorded and compared to the white blood cell numbers collected in the first phase of the study.

According to the researchers, the effect of sleep loss on the white blood cells was immediate. The white blood cells known as granulocytes showed a loss of day-night rhythmicity—the circadian rhythm of the granulocytes slowed—and their numbers also increased, particularly at night. This reaction directly mirrors the body’s white blood cell response to stress.

Read the full study entitled, “Diurnal Rhythms in Blood Cell Populations and the Effect of Acute Sleep Deprivation in Healthy Young Men,” published in the July 2012 issue of the journal, Sleep. 

The results of the study are in line with other previous research that shows a link between lack of sleep and a negative immune system response. In March of this year, the University of Rochester Medical Center published results that showed that the immune system of older adults who do not get enough sleep responds to stress with inflammation, increasing the risk for mental and physical health problems.

These studies and others like them reinforce the fact that more quality, restful sleep not only helps us feel better – it may also help us avoid myriad poor mental and physical health conditions. So, get some sleep out there — you’ll feel less stressed out!

Another Reason: Oxygen Depletion from OSA Linked to Higher Rate of Cancer

Every month, I take time to write these blogs to help educate people about the negative health effects associated with obstructive sleep apnea (OSA), and the importance of getting it properly diagnosed and treated. I hope my point is getting across out there.

If you or someone you love regularly experiences OSA symptoms, such as snoring and disordered (interrupted) breathing, here’s another reason to get it checked out: Two new studies claim that OSA sufferers are more likely to die from cancer.

Their findings are significant because it marks the first time that cancer growth has been associated with sleep apnea in people. In a previous study about a year ago, Spanish researchers had already linked the intermittent lack of oxygen caused by OSA—known as hypoxia—with increased tumor growth in mice. That study also found that the mice had more dead cells, which indicates a more aggressive type of cancer.

In one of the new studies, researchers at the University of Wisconsin School of Medicine and Public Health studied data on about 1,500 state workers who have been taking part in overnight sleep studies every four years since 1989.

The researchers found that people with severe sleep apnea who had the most intermittent disordered breathing problems were almost five times more likely to die from cancer than those without OSA. They also found that people considered to have moderate cases of OSA died of cancer at double the rate than those without OSA at all.

This is consistent with the hypoxemia theory—that an increase of interrupted/disordered breathing is actually contributing to cancer cell growth … because the body is being depleted of oxygen.

What the researchers also discovered—and what I found particularly notable—was that when OSA patients who were being treated with continuous positive airway pressure (CPAP) therapy were removed from the Wisconsin study, the OSA/cancer association increased.  In other words, OSA patients who undergo CPAP treatment—who lower their interrupted/disordered breathing episodes—may likely reduce their risk of dying from cancer due to OSA-related oxygen depletion.

In the second related study, researchers at the Spanish Sleep Network used the hypoxemia index, which measures the amount of time the level of oxygen in a person’s blood drops below 90 percent at night.

The researchers followed more than 5,000 OSA patients for seven years. None of them had any cancer diagnosis when the study began, but they found that those with the most severe forms of sleep apnea had a 65 percent greater risk of developing cancer of any kind. In other words, the greater the extent of oxygen depletion during sleep, the more likely a person was to be diagnosed with cancer during the study.

It should be noted that, in both the Wisconsin and Spanish studies, the researchers only looked at cancer diagnoses and deaths in general, not the specific type of cancer.

The takeaway for all of is that this is one more study … one more reason … for you or someone you love with OSA-related paused/intermittent breathing issues to take sleep apnea seriously and get diagnosed asap.

One More Reason to Get Checked: Sleep Deprivation Can Cause Weight Gain

It’s no surprise that I use my blog as a forum to educate you on various sleep disorders, and the many reasons to get them diagnosed and treated properly. At the risk of sounding alarmist, not getting a sleep issue checked out—even one you may think is fairly benign—can have dire consequences.

Conditions such as sleep apnea that cause sleep deprivation are linked to poor concentration and memory, increased risk of diabetes, hypertension and high blood pressure, heart attacks and strokes, depression and sexual dysfunction.

As if these reasons aren’t enough to scare you into getting tested, here’s another one that just came out: Lack of sleep is now linked to overeating, and as a result, weight gain. That information was just announced at the American Heart Association’s Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism 2012 conference in San Diego.

To be more specific, according to the study’s abstract, sleep is an important regulator of metabolism and energy expenditure. When acute sleep deprivation occurs, the hormone leptin is reduced, while the hormone ghrelin is increased, promoting caloric intake, but not energy expenditure. The likely result is weight gain.

A quick lesson in endocrinology:

Leptin and ghrelin are appetite hormones. Leptin helps regulate hunger, appetite, and metabolism. When you have low levels of leptin in the body—perhaps due to sleep deprivation—the hormone will tell receptors in the hypothalamus of the brain, “Hey, I’m hungry, feed me.” Normal healthy levels of leptin, on the other hand, will let the brain know that you’ve had enough and are no longer hungry. 

Ghrelin is known as the hunger hormone because its job is to tell the hypothalamus when you are hungry and need to eat. That is why ghrelin levels are elevated in the body when you are hungry, and decrease after you have eaten. Ghrelin also promotes fat storage, and has been linked to the accumulation of abdominal fat.

It stands to reason, then, that if sleep deprivation reduces leptin—causing you to feel hungry—and increases ghrelin—also causing you to feel hungry and eat, then sleep deprivation is likely to lead to overeating and weight gain.

So, how did the researchers come to this conclusion?

Virend Somers, M.D., Ph.D., professor of medicine and cardiovascular disease at the Mayo Clinic, Rochester, Minnesota and his colleagues conducted an eight night sleep test on 17 people—11 men and six women—between the ages of 18 and 40.

Eight of the subjects in the “random group” were made to sleep less than they normally do, while the other nine in the “control group” slept their normal amount of time.

All subjects were able to eat as much as they wanted throughout the testing periods, and their daily caloric intake was measured. In addition, their daily sleep times and energy expenditures were measured, and their blood was collected at the end of the test period.

The results of the test are interesting: The sleep deprived group—who slept one hour and 20 minutes less than the control group per night—ate around 549 more calories per day than the normal sleep group. However, the sleep deprived group who ate more did not expend much more energy than the normal sleep group.

The conclusion again is: Less sleep, plus more calories and no increased activity equals more weight gain. It’s a vicious cycle. So let’s turn this equation around. When you sleep well and get enough rest, you help your body to function properly, including your appetite, metabolism and the hunger hormones mentioned above.

And so I continue my tireless crusade against sleep disorders. If you’re having trouble sleeping, from sleep apnea, snoring or some other disorder, get it checked out and treated by a qualified sleep doctor. Doing so could save you a lot, including a few notches around your belt.

To read the abstract of the study, see Insufficient Sleep Increases Caloric Intake but not Energy Expenditure.

Sleepy on the Job? Tips for a Better Night’s Sleep

There’s no denying that sleep deprivation, and the health issues that result, are becoming more prevalent in our go-go, techno society. But a recent sleep study by the National Sleep Foundation (NSF) grabbed my attention as particular cause for concern.

Every year, the NSF releases a Sleep in America® poll.  For its 2012 survey, the NSF examined the specific sleep habits and work performances of transportation workers—pilots, train operators, truck, bus, taxi and limousine drivers. The transportation workers were asked about the duration and quality of their sleep, specifically on work nights, and how it affects their work performance.

Some of the results of the survey are:

• About one-fourth of the train operators and pilots polled said that sleepiness has affected their job performance at least once a week.
• One in five pilots polled—about 20 percent—said they have made a “serious error” as a result of on-the-job sleepiness.
•  One in five pilots and one in six train operators admit to a “near miss” due to on-the-job sleepiness.
• Pilots and train operators are more likely than non-transportation workers to have been involved in a sleep-related car accident while commuting.
• Among all workers surveyed, train operators and pilots report the most work day sleep dissatisfaction.
• Almost two-thirds of train operators and one-half of pilots say they rarely or never get a good night’s sleep on work nights.
• About one-third of bus, taxi, and limo drivers said they rarely or never get a good night’s sleep on work nights.

The results of the poll are some cause for alarm, and reinforce the growing problem of sleep disorders and the potential risks they pose, such as commuter car accidents and errors by public transportation drivers responsible for many people.

Persistent sleep problems left untreated can also lead to myriad health problems, including memory and concentration problems, increased risk of high blood pressure, hypertension, stroke and heart attacks, depression, diabetes and sexual dysfunction. Severe cases of sleep apnea can even be fatal.

Besides these sobering health risks, an untreated sleep disorder can also be the root cause of poor performance at work or school, car accidents and other activities that require focus and concentration.

Common Symptoms of Sleep Disorders

Many people experience some occasional difficulty sleeping and/or daytime fatigue. But how does a person know if he or she has a temporary sleep problem that can be remedied with some simple behavioral changes, or if it is a legitimate disorder such as snoring, sleep apnea, sinusitis or nasal obstruction that should be diagnosed and treated properly?

The first step is to be aware of some common symptoms of sleep disorders. Keep in mind that symptoms vary between disorders, such as snoring, sleep apnea, insomnia, restless leg syndrome, nasal obstruction, narcolepsy, so it pays to do some research based on what you are personally experiencing.

Some common symptoms of sleep disorders include:

• Trouble falling asleep at night
• Waking throughout the night
• Chronic snoring
• Morning headaches
• Poor memory
• Daytime sleepiness/falling asleep during the day/low energy
• Bad moods/ irritability
• Increased depression
• Trouble concentrating/driving/making decisions

The Link Between Lifestyle and Sleep Problems

If you or someone you know is experiencing some of the above common symptoms of sleep disorders, the next step is to examine if lifestyle habits are contributing to the difficulty sleeping, fatigue and irritability during the day and other symptoms.
Some behavioral/lifestyle questions to ask include:

• Am I watching TV or using the computer late at night and too close to bedtime?
• Am I consuming too much caffeine during the day?
• Am I taking a medication that may be affecting my sleep quality and duration?
• Is there something particularly stressful going on in my life that is causing me worry and anxiety?
• Am I exercising enough to help alleviate some of that stress and tension?

See a Specialist—And Be Specific

Many sleep problems can be remedied by making some common sense behavioral changes. However, if you or someone you know is experiencing one or more of the above symptoms on a regular basis, see a qualified ear, nose and throat doctor or otolaryngologist to get diagnosed and treated properly. There are multiple options and minimally invasive techniques available today to treat your sleep disorder.

When you see a specialist, be specific about the symptoms you are experiencing. Many times, sleep apnea and other sleep disorders can be misdiagnosed as chronic fatigue, insomnia, depression, or some other non-specific condition. Some doctors, for example, still associate sleep apnea more with men than women, and are too quick to prescribe a medication, rather than do a full sleep disorder work up.

It may help to keep a sleep log (or, more accurately, lack of sleep log) next to your bed to write down what you are experiencing, when you wake and some symptoms you experience. Again, to try and avoid misdiagnosis, go to a qualified sleep specialist and be specific about your symptoms. Don’t wait — it could save your life.

To read the full report, see “Sleepy Pilots, Train Operators and Drivers”  on the National Sleep Foundation website.

How Do You Know if You Have a Sleep Disorder

Many people experience some occasional difficulty sleeping and/or daytime fatigue. But how do you know if your sleep problem is temporary and can be fixed with some simple behavioral changes, or if it is a legitimate disorder such as snoring, sleep apnea, sinusitis or nasal obstruction that should be diagnosed and treated properly?

That is one of the most common questions we get here at Eos Sleep.

The first thing you can do is take an honest look at your lifestyle habits. Are you watching TV or on the computer too close to bedtime? Consuming too much caffeine during the day? Taking a medication with sleep-related side effects? Is there something particularly stressful going on in your life that needs to be addressed?  Are you exercising enough to help relieve tension and anxiety? The good news is that many sleep “issues” can be remedied by making some common sense behavioral changes.

However—and I would be remiss if I didn’t mention it at this point—persistent sleep problems left untreated can lead to myriad health problem, including memory and concentration problems, increased risk of high blood pressure, hypertension, stroke and heart attacks, depression, diabetes and sexual dysfunction. Severe cases of sleep apnea can even be fatal.

Besides these sobering health risks, an untreated sleep disorder can also be the root cause of poor performance at work or school, car accidents and other activities that require focus and concentration.

New research is exposing the societal risk that can result from untreated sleep apnea and other sleep disorders. The National Sleep Foundation’s 2012 “Sleep in America” poll, which focused in on the sleep habits and performance of transportation workers, states that about one in 10 Americans are likely to fall asleep at an inappropriate time and place, such as during a meeting or while driving.

Other results of the study: About one-fourth of polled train operators (26%) and pilots (23%) admit that sleepiness has affected their job performance at least once a week, compared to about one in six non-transportation workers (17%).

Even more concerning: One in five pilots (20%) admit that they have made a serious error and one in six train operators (18%) and truck drivers (14%) say that they have had a “near miss” due to sleepiness.

The numbers are in: Sleep problems are prevalent in our society, and people need to wake up (no pun intended) to the symptoms and risks associated with them. Some common symptoms of sleep disorders include:

•    Trouble falling asleep at night
•    Waking throughout the night
•    Chronic snoring
•    Morning headaches
•    Poor memory
•    Daytime sleepiness/falling asleep during the day/low energy
•    Bad moods/irritability
•    Increased depression
•    Trouble concentrating/driving/making decisions

Keep in mind that symptoms vary between disorders, whether it’s snoring, sleep apnea, insomnia, restless leg syndrome, nasal obstruction, narcolepsy or some other sleep disorder,  so it pays to do some research based on what you are personally experiencing. If you experiencing one or more of the above symptoms on a regular basis—meaning, more than once in a blue moon—it is imperative that you see a qualified sleep doctor, and get diagnosed and treated properly. The good news is there are multiple options and minimally invasive techniques available today to treat your sleep disorder.

Women and Sleep Apnea: At Greater Risk Than We Thought

A few months ago, my blog entitled, “Who’s Suffering More from Lack of Sleep — Men or Women?”  discussed “the sleep battle of the sexes,” specifically, who suffers more from sleep disorders — men or women? In that blog, I made the point that, while men are generally more likely to suffer from obstructive sleep apnea (OSA) than women, men are also more likely to get tested and treated for the disorder.

That’s not good, because we are learning that many more women than previously thought suffer from OSA, and leaving it unchecked can have dire consequences on a woman’s cardiovascular health.

I read a recent women and sleep apnea study out of Spain that said that women with untreated severe OSA are three and a half times more likely to die from cardiovascular disease than women without OSA. Three and a half times!

Thankfully, the study also showed that women who treat their severe sleep apnea at night with a technique called continuous positive airway pressure (CPAP) significantly reduce their risk of heart attack-related deaths to about the same risk level as women without OSA.

The study was conducted by Dr. Francisco Campos-Rodriguez, director of the sleep-disordered breathing unit at Valme University Hospital in Seville, Spain. To read a summary of the study, go to the Annals of Internal Medicine.

The research is a wake-up call to both patients and doctors because it is the first published results that link OSA to cardiovascular death in women, and that CPAP treatment can reduce OSA-related mortality risk.

It also shines a light on the need for more research regarding sleep apnea and women, as well as the need for women to take their symptoms seriously, and not just consider OSA “a man’s disease.”

What Women Should Know About Sleep Apnea

So how do you know you may have obstructive sleep apnea? Some common symptoms include snoring, paused breathing during sleep and excessive sleepiness during the day. Increased blood pressure is another sign you may have sleep apnea.

While sleep apnea is more common in men, OSA increases in women after age 50. According to the National Sleep Foundation, one in four women over age 65 have sleep apnea.

Being overweight also increases a woman’s risk of having sleep apnea. Menopausal women are three and a half times more likely to get OSA, possible due to reduced amounts of progesterone.

If you have any of the symptoms mentioned above, and suspect that you may have sleep apnea, please get checked out by a doctor who specializes in sleep disorders. Be specific about the symptoms you are experiencing. Many times, sleep apnea can be misdiagnosed in women as chronic fatigue, insomnia, depression, or some other non-specific condition.

Also, some doctors still associate sleep apnea more with men than women, and are too quick to prescribe a medication, rather than do a full sleep disorder work up. Again, to try and avoid misdiagnosis, go to a qualified sleep specialist and be specific about your symptoms. Don’t wait — it could save your life.

The Relationship between Seasonal Affective Disorder and Sleep Problems

One of the most common questions I get in the office during the winter months has to do with seasonal affective disorder: What is it? Do I have it? And what can I do about it? Seasonal affective disorder is a very real form of depression that may affect six out of every 100 people in the United States, according to the American Academy of Family Physicians.

Symptoms of SAD generally manifest in late fall, when the days become shorter and colder, and people enjoy less natural sunlight. Symptoms include, but are not limited to, feelings of sadness, hopelessness and helplessness, lack of energy, loss of sexual interest and usual pleasurable activities, irritability and restlessness, cravings for carbohydrates and overeating (which can lead to weight gain and compound negative and depressive feelings), trouble concentrating, difficulty sleeping and/or insomnia and at the extreme end—thoughts of death or suicide. Symptoms of SAD are usually most intense during the darkest months of the year, so it stands to reason that the farther a person lives from the equator, the higher the incidence of SAD occurs.

These sleep-related symptoms are of particular interest to me, and are usually the catalyst for a person with SAD to come see me for a consultation and treatment. A person with SAD who suffers from sleep problems may go to sleep early and stay in bed for nine or ten hours, but not experience refreshing sleep.  Because of a lack of restful sleep, people with SAD are often drowsy and have trouble concentrating and working during the day.

The relationship between sleep and depression is a bit of a “chicken or the egg” relationship. Which came first? SAD-related depression, or the sleeping problems? It depends. For some, symptoms of SAD occur first—for others, sleep problems appear first. Depression may cause the sleep problems, and sleep problems may cause or worsen the other SAD symptoms.

There is a common link between people with depression and insomnia. Studies have shown that people with insomnia have a ten-fold risk of developing depression compared with people who sleep well. Further, developing depression is highest among those with both sleep onset and sleep maintenance insomnia.

People with depression may also experience insomnia symptoms, including difficulty falling asleep, difficulty staying asleep, experiencing restful sleep and daytime sleepiness. People who suffer from depression are also five times more likely to have a breathing-related sleep disorder than non-depressed people, according to a study at the Stanford University School of Medicine. The 2003 study by Stanford researcher Maurice Ohayon, MD, PhD, found that people with depression were found to be five times more likely to suffer from obstructive sleep apnea (OSA), the most common form of sleep disordered breathing. This was one of the first studies to make the connection between depression and sleep disorders.  More current research has confirmed the connection.

So, if you believe you are experiencing SAD-related depression and/or sleep disorders, please see a psychiatrist or sleep specialist about it. There are treatments such as morning light therapy that can offer some relief, so you don’t have to suffer unnecessarily through the winter blues. Call me—I’m happy to help.

Who’s Suffering More from Lack of Sleep—Men or Women?

This week, I was interviewed by WCBS-TV New York for a news segment called, “Sleep: the Battle of the Sexes.” The topic was one I am very familiar with: People suffering from lack of sleep, and how it can affect daytime mood, mental acuity, job performance and relationship intimacy.

The show drilled down a bit farther and asked: who is more likely to suffer from a sleep disorder, men or women? And of the two genders, which performs better despite a lack of sleep?

What we know is that men and women have different circadian rhythms. According to an article by the Proceedings of the National Academy of Sciences of the United States of America,  “The circadian rhythms of melatonin and body temperature are set to an earlier hour in women than in men, even when the women and men maintain nearly identical and consistent bedtimes and wake times. Moreover, women tend to wake up earlier than men and exhibit a greater preference for morning activities than men.”

In other words, women tend to go to sleep and wake up earlier than men. We also know thanks to a Penn State study that women need 6.8 hours of sleep per night, while men require just 6.2 hours. While scientific studies are interesting, there is a discrepancy between these numbers and what I am seeing in my office at the Manhattan Snoring and Sleep Center.

Based on the facts, one would think women are getting to sleep earlier and sleeping longer than their male counterparts. But are women getting the sleep they need? In my anecdotal opinion, they are not, and they are suffering quietly for it. In our society, men are stressed out, but women are really stressed out. The physical demands of balancing career and family, along with the mental strain of worrying about finances and future is taking its toll on the women in our society. 

Don’t get me wrong, men worry and suffer from sleep disorders too. But they seem more willing to speak up and seek treatment. Women, on the other hand, being the selfless caregivers they are, stay focused on others and what needs to be done and power through their day. Which explains another Penn State study that found sleep deprived women made fewer mistakes compared to men in a series of computer tasks. It seems that, although women need more sleep, they do better without it because, for better or worse, they’re just more used to it.

Whether a man or woman is suffering from a lack of sleep, the fact is that a sleep disorder can lead to negative health issues, including an increased chance of hypertension, heart disease, osteoporosis and inflammatory disease.

In addition to personal health issues, a sleep disorder can wreak havoc on a relationship. The partner of a patient once shared with me how his snoring and sleep apnea had impacted their relationship. It led to weeks without quality REM sleep, and she said it left her feeling groggy with low energy, cranky, unable to concentrate for long and she was more prone to getting sick. His constant snoring caused her to start sleeping on the couch, which led to resentment, lack of intimacy and loss of connection.

I have made it clear in previous blogs that I am not a marriage counselor or relationship expert. But I can tell you unequivocally that, if you or your partner snores or suffers from a lack of sleep on a consistent basis, it will negatively affect your relationship.

In the end, circadian rhythms and who performs better and the sex of the person with the sleep disorder doesn’t matter. What matters is getting it treated and keeping the relationship healthy.

This also bears repeating: Turn off the TV when you go to sleep. Falling asleep with the TV or computer on interrupts deep REM sleep because the light from the screens interfere with the production of melatonin, a hormone that tells our bodies when it’s time to go to sleep. Do yourself a favor and turn off the TV, computer and lights at night. Your brain and body will thank you for it the next day.

Mending Your Relationship When Snoring Rips You Apart

Snoring is a major cause of couple's unhappiness.

Although in this blog I generally discuss the health consequences of snoring, I’d like to bring to light another serious side effect, which is the devastation snoring can wreak on marriage. Often I meet with married couples in my practice who are at their wits end. Both partners are exhausted…the snorer because of the toll snoring takes on their body, and the spouse whose health is impacted dramatically from their partner’s snoring because of the daytime fatigue brought on by their inability to get a healthy full night’s sleep.

According to a new study by the British Lung Foundation (BLF)¹, loud snoring forces more than a third of couples to sleep in separate beds at night. The foundation polled more than 2,500 adults through an online survey in the United Kingdom this past Spring. Even more drastic for these couples is the fact of the 39% who admit they sleep apart, a full third (33%) claim it has become a permanent sleeping arrangement. Certainly sleeping apart from your significant other all the time can’t be healthy for the relationship. In addition to the noise of snoring creating distance between couples, snoring can also be a factor that leads to sexual dysfunction in men, according to a study² that was reported in The Journal of Sexual Medicine.

When couples feel that snoring is ripping their marriages apart, it is often because they are both tired, irritable and tense. If they have been sleeping separately, most likely their relationship has eroded, and their communication has faltered. Certainly the lack of intimacy—not just physically, but the relaxing interactions between companions such as pillow talk—has worn them down.

How intrusive is snoring in a marriage? In 2006, a study from the Rush University Medical Center in Illinois3 determined that couples have a high divorce rate when the husband snores due to sleep apnea. Sleep apnea is the most serious of the many causes of snoring because it causes the snorer to stop breathing multiple times throughout the night, which can lead to heart and lung issues, high blood pressure and stroke. For years many snorers were reluctant to seek treatment because some of the most common treatments involved cumbersome sleep masks or surgery. Thankfully, today there are a number non-invasive in-office techniques that successfully treat the varied types of snoring such as the Pillar® Procedure, Balloon Sinuplasty™, and more based on the individual cause of your snoring.

Although I’m not a marriage counselor or sex therapist, patients who come to the Manhattan Snoring and Sleep Center are taking a positive step to mend their relationship and hopefully will not become one of the statistics of divorce due to snoring. They are not only mending their relationship, but they are taking control of their health, leading to a more fulfilling life.

My marital advice to snorers? Seek treatment and enjoy getting close to your partner again.

A Snorer’s Guide to Summer Travel

Summer Vacation

School is out and summer travel plans are getting underway. Whether you’re planning a camping trip, renting a house on the shore for a week, or visiting relatives on the other side of the country, summer is a way for us to relax and reconnect with family.

Unfortunately, if you’re one of the 50 million Americans who snore, sharing close quarters can not only be embarrassing, but put a damper on the entire vacation if you’re a guest in someone’s home or as a housemate in a vacation home. While your spouse may have learned to adjust to the noise of your snoring, it’s important to understand that your snoring can also interfere with the sleep patterns of family and friends in close proximity.

When someone is prevented from receiving their requisite hours of recuperative sleep, it can lead them to be irritable, experience daytime drowsiness, affect their ability to concentrate, and interfere with their response time when they drive.  Absolutely nothing can ruin a vacation faster than cranky, over-tired children, and/or their parents.

However, realizing that your snoring is a problem that can be avoided, and by taking some steps ahead of time, you can prevent the issue altogether and ensure that your vacation will be full of energy and fun.

In-Office Procedures:

There are a few relatively new procedures that cure or drastically eliminate snoring that can be performed in just a few minutes in a snoring specialist’s office:

ThePillar® Procedure can be performed in a doctor’s office in about 20 minutes using only local anesthetic. It is effective to treat snoring that is caused by the fluttering of the soft palate, which occurs when the muscles in the back of the throat relax while asleep. The procedure involves three small polyester implants that are placed into the soft palate and over time, the implants, together with the body’s natural fibrotic response, provide support and stiffen the soft palate. This minimally invasive, simple and safe treatment for snoring and mild to moderate snoring including snoring caused by Obstructive Sleep Apnea, is a relatively painless procedure that is giving hope to snorers everywhere.  

Balloon Sinuplasty™ is another relatively new procedure to treat blocked sinus passages for snoring that is caused by chronic sinusitis. It can also be performed in a doctor’s office on an out-patient basis. It uses a small, flexible, sinus balloon catheter to open up blocked sinus passageways. When the balloon inflates, it widens the walls of the passageway while maintaining the integrity of the sinus lining, and restores normal sinus drainage.

When the sinus balloon is inflated, it gently while maintaining the integrity of the sinus lining.

Over the counter treatments: There are additional treatments a snoring specialist can recommend that can aid you while on your vacation that don’t necessarily include other types of surgery. For example if obstruction in the nose or sinus cavity is the cause of your snoring, many patients get relief from using nasal strips. Antihistamines, decongestants as well as topical and systemic corticosteroids can also be of assistance.

Lifestyle Adjustments: Your snoring specialist may ask you for some lifestyle modifications before any of the above treatments are recommended. That is because there are a variety of influences that could cause you to snore.

•  Lose 5-10 pounds. Excess weight is the most common contributing factor to snoring. If there is time before your vacation, try losing weight,
  because even those that are mildly overweight find that weight loss can significantly reduce their snoring with even a modest weight loss of five to ten pounds.   
• Quit smoking. Since snoring leads to irritation and dryness of mucous membranes, quitting cigars or cigarettes is a lifestyle change that can have a dramatic impact on snoring. 
• Reduce consumption of alcohol and sedatives. Alcohol, sedatives, and sedating antihistamines lower muscle tone in the upper airways, causing an increased airway resistance and snoring. Many people who reduce these substances report improvements in their snoring. 
• Change your sleep position. For some people, an increased amount of obstruction occurs when they sleep on their backs. Described as positional snoring, this type of snoring can have a simple solution. Sew a ball into the pocket of a t-shirt and wear it backwards. This will keep you off your back during sleep.
• Get an extra pillow. Some positional snorers also improve when the head of the bed is elevated.
• Pack some earplugs. If you’re worried that the loudness of your snoring still won’t be under control, do your fellow vacationers a favor, and pack some earplugs for them. They’ll thank you for it.

With a little forethought, your snoring doesn’t need to interfere with you or your fellow
vacationer’s sleep. Contact a snoring specialist near you today to get the treatment you need, to relax and enjoy your summer travels.
