The Impact of Ageing on Sleep

It seems like every day we learn more about the importance of a full night of beneficial and restorative sleep; we understand that it impacts every portion of our lives and without it, we are vulnerable to a myriad of diseases and chronic conditions. Yet, for many of us and for many reasons, that type of sleep is so very difficult to come by.

Unfortunately, as we age it becomes even harder. Older adults face a reduction in the quantity and quality of deep sleep, the stage that beneficially overhauls our cardiovascular, immune and metabolic systems and refreshes learning and memory abilities. Beginning in our 30s, each decade represents a significant decline in the restorative deep sleep we experienced when young.

In addition, our sleep also becomes more fragmented; we wake up more during the night, perhaps because of a weakened bladder or aches and pains.

Scientists also have determined that the circadian rhythms (the body’s internal wake/sleep clock) of older people change, resulting in our bodies calling for earlier bedtimes and earlier risings which can disrupt our sleep cycles.

Ageing in general can cause a deterioration in our health, but we are learning that the deterioration of our sleep may be more in play than we previously thought. As we age, we should continue to pay attention to our sleep patterns and discuss them with our doctors. There are steps that can and should be taken to improve and maintain a better night’s sleep….learn about them

Drowsy Driving

A new report issued earlier this month by the Governors Highway Safety Association identifies drowsy driving as the factor in crashes that claimed 5,000 lives in 2015. It is estimated to cause 20 percent of all traffic deaths which increased by 8 percent last year. The annual cost of fatigue related accidents that cause injury or death is $109 billion, not including property damage!

Because nearly 84 million sleep deprived Americans are on the road each day, the National Highway Traffic Safety Association (NHTSA) has expanded its definition of impaired driving to include drowsy driving, in addition to drunk, drugged and distracted driving. The drivers who are at greater risk of driving while tired are teens and young adults, shift workers and those with sleep disorders. Too little sleep causes drivers to react more slowly, resulting in injuries and death.

The report recommends Americans change their view of sleep; it should be considered an essential element of a healthy life, along with eating right and exercising.

Not Just For Kids!

Naps…they really are not just for kids! Dr. Damien Leger, a French sleep researcher, writes that napping should be considered a basic right, not a luxury or an activity to be hidden or derided. He stresses how important they are for those who work nights and/or for those who routinely sleep six or less hours per day, since studies have shown that chronic sleep deprivation is associated with diabetes, depression, cancer, obesity and even an increased risk of death.

Dr. Leger does note there are conditions for taking an effective and successful nap. He advises that it should be limited to 20 minutes (set your alarm!) as anything more might leave you with “sleep drunkenness”, rather than the rejuvenation which is sought. Also, find a safe place to sleep whether it is your desk (it is not necessary to lay down), car or an empty office or workspace.

Research has shown that naps or short periods of sleep increase cognitive performance, reaction time and mood, so take the time and try a nap; you may be thrilled with the results!

New CDC Sleep Study

 

At Working Nights we often discuss the importance of sleep and the obstacles shift workers face in trying to get enough of it. Lack of sleep is not only a major issue for shift workers but for many adults (and unfortunately, a growing number of children) in the world. The Centers for Disease Control and Prevention (CDC) report that, according to a new sleep study, more than one third of adults in America are not getting enough sleep on a regular basis. This study is the first to document estimates of self-reported healthy sleep duration (identified as 7 hours or more) in all 50 states and Washington, D.C.

To learn more about the study and about some steps you can take to increase the quantity and quality of your sleep, go to the Centers for Disease Control and Prevention website.

The Effects of Interrupted Sleep

Ask yourself how often you get a full uninterrupted night’s sleep… do you ever? If your answer is sometimes, rarely or never, you are not alone!

We now know that sleep impacts EVERY part of our mental, physical and emotional lives and that it is the number one ingredient for optimum health. Knowing that, we usually worry about the number of hours of sleep we get and do not as often consider the quality of those hours. A recent study suggests we should….read about the impact of disrupted sleep at (e) Science News.

Sleep…the Key to Staying Healthy This Winter!

Sleep is a subject being studied by researchers more than ever as they continue to learn how it impacts every part of our mental, physical and emotional lives. Working Nights discusses it often since shift workers, due to their unique hours and the disruption of their circadian rhythms, get less sleep than the day working population.

The Centers for Disease Control and Prevention (CDC) call insufficient sleep a public health epidemic. The National Sleep Foundation reported in their 2013 survey that one in five Americans get less than six hours of sleep on an average work night.

As we approach winter and cold and flu season, we need to try even harder to get more undisturbed quality sleep (we are turning the clocks back this Sunday, November 1st, so there is an extra hour!). Working Nights looked at the results of a new UC San Francisco study on the relationship between shortened sleep and catching a cold or virus. Those results show  that those who slept less than six hours a night were 4.2 times more likely to catch a cold; the odds increased for those who slept even less!

Are You Sitting Too Much?

In recent years there have been numerous articles written about the physical toll of being sedentary. Excessive sitting is associated with 34 chronic diseases and conditions! Studies show that sitting too much has been linked to cardiovascular events like heart attack, heart disease death, overall death and death from cancer. It has also been associated with high blood pressure, obesity, bad cholesterol and too much belly fat.

Dr. David Alter, the senior scientist of a new study on sitting at the University Health Network (UHN) in Toronto said, “More than one-half of an average person’s days is spent being sedentary — sitting, watching television or working at a computer.” Studies have reported that people who sit for long periods were 24 percent more likely to die from health problems during the studies, which lasted between 1 and 16 years, compared to those who sat less.

And now the results of a new study in Australia indicate there is yet one more reason to get up from your chair….in addition to the physical impacts, there is evidence that there is a link between too much sitting and emotional stress; that is the more sedentary a person was, the more likely he or she was to feel anxious. Only nine studies have so far examined this link, so additional research is needed.

However, ultimately, the bottom line is sitting for a long period of time is bad for you, even if you are active and exercise regularly. Knowing this, make a point of getting up every hour or so….grab a drink, walk over to a co-worker’s desk, choose to stand more when you have a choice…it is worth it!

No More Excuses!

Most of us know the importance of exercise, but still come up with excuses not to do any.  It may be too hot, too cold, too wet or too snowy. You may be too tired, too busy or too stressed. It is not easy to start an exercise regimen; it is even more difficult when working evenings or nights. Yet, the benefits of exercise so outweigh any excuse we may come up with that it is worth a second look and try.

This week WebMD details the 12 Rewards of Exercise. All of the benefits discussed can only make our lives better; how would you like to get a better night’s sleep, have more energy, be more productive and be less stressed? And these are only some of the rewards……

Keep in mind that you don’t have to start running marathons. Find an activity or exercise you are interested in and like; find the time to do it (there is always some time available) and go from there. Who knows…..you may eventually be in that marathon!

Less Might Be More

Good news for shift workers! The Wall Street Journal is reporting that recent sleep studies have found that 7 hours is the optimal amount of sleep, not 8 as were recommended in the past. One study showed that cognitive performance increased as people got more sleep, reaching a peak at seven hours before starting to decline. Another found the lowest mortality and morbidity with 7 hours. Researchers are also reporting that too much sleep may be as harmful as too little sleep. The new sleep guidelines are expected to be issued in 2015.

Experts agree though that the optimal amount of sleep is what is right for each individual. Learn how you can determine what is right for you and learn more about the new sleep studies..

Is There a Link between Sleep and Alzheimer’s Disease?

 

Last month we wrote about a new study that described how the brain cleans itself as we sleep by flushing out the toxins accumulated during our waking hours. We noted that the results of this study are of great interest to Alzheimer’s researchers because one of the byproducts that is cleaned out daily is beta-amyloid, clumps of which form plaques found in the brains of AD (Alzheimers Disease) patients.

Sleep patterns have previously been linked to beta-amyloid plaques. Researchers from The John Hopkins Bloomberg School of Health have observed that those with AD spend more time awake and have more fragmented sleep patterns than those without the disease. They wanted to determine whether there was a link between beta-amyloid deposits and sleep within community-dwelling older adults.

The test group for their study consisted of 70 adults with an average age of 76; none of the participants had any form of dementia. They were asked to record their sleep patterns which included the duration of sleep and any trouble falling or staying asleep. Various brain imaging techniques were used to measure the beta-amyloid deposition in their brains.

The researchers report that the results of this study were consistent with those from animal research in which sleep deprivation increased interstitial fluid beta-amyloid levels. They note that this could have a tremendous impact on public health as AD is the most common form of dementia and almost half of older adults with the disorder report insomnia based symptoms. They say that “because late-life sleep disturbance can be treated, interventions to improve sleep or maintain healthy sleep among older adults may help prevent or slow AD to the extent that poor sleep promotes AD onset and progression.

The emotional, financial and logistical costs of AD are significant and will only increase as our population ages and more people are diagnosed. Further testing and research regarding sleep and its connection to AD continue to be conducted. The Cure Alzheimer’s Fund of Wellesley Hills, MA, dedicated to ending Alzheimer’s Disease, is currently funding a proposal on this subject.

Is the Restless Legs Mystery Solved?

Restless legs syndrome (RLS) is a subject of concern to shift workers because it often disrupts their already limited hours of sleep. It is a disorder that causes a strong urge to move your legs, usually when you are sleeping or inactive, resulting in difficulty getting to sleep and maintaining sleep.

The good news is that researchers continue to study RLS in order to try to improve suffer’s sleep.  Studies have shown that RLS patients’ sleep is not significantly improved even when their involuntary leg movements are reduced by certain drugs; this has been a mystery to researchers. However, new findings by Johns Hopkins researchers, published in the May issue of the journal Neurology, show this mystery may have been solved. To learn more about these results, read the article in e! science news.

Can lost sleep be recovered?

We all know that sleep deficit is a constant problem for many shift workers. And we also know that having a sleep debt impacts every faction of our lives. So the debate continues – what is the best way to make up that sleep? A May 20th article in the Wall Street Journal discusses this issue and offers some suggestions.

What is best for you, your schedule and your sleep type? Should you sleep binge, sleep bank or nap? Click here to learn more….

A.D.H.D. or Sleep Deficit?

At this point, it appears we all know someone (if not yourself!) who has been diagnosed or has symptoms attributable to attention-deficit hyperactivity disorder or A.D.H.D. The classic symptoms of A.D.H.D. include procrastination, forgetfulness, the inability to pay attention consistently and the propensity to lose things. However, as a recent article published in the New York Times points out, there is an important diagnostic criterion: symptoms must date back to childhood.  Yet, in many patients, it has been shown they don’t.

Vatsal G. Thakkar, the article’s author, proposes that in a substantial number of cases, these symptoms may be a result of chronic sleep deficit! In today’s 24/7 society, we all get less sleep than we used to, especially shift workers. We at Working Nights often discuss the importance of sleep and what happens if we do not get enough. It has a tremendous negative impact on our health and wellbeing. Learn more about these sleep findings by reading the article in the New York Times.

Breaking News from the National Sleep Foundation!

In the past, sleep experts had warned us about exercising too close to bed time. They said excitement hormones such as adrenaline, which rise during exercise to give us energy and take about three hours to fall back to normal levels, would interfere with a good night’s sleep.

However, recent studies show this is not the case! These studies indicate that the timing of your exercise has no impact on your quality or quantity of sleep. This research is backed by a survey released by the National Sleep Foundation (NSF) which makes the case for exercising to improve sleep, regardless of the time of day or night. The survey polled vigorous exercisers who, whether exercising first thing in the morning or right before bed, were twice as likely as sedentary people to report they had a good night’s sleep every night or almost every night the week before. Therefore, the NSF has amended its recommendation for normal sleepers to encourage exercise at any time of day or night.

This is wonderful news for shift workers who often find it difficult to get to sleep and to fit exercise into their schedule. To learn more about this new information, go to the National Sleep Foundation’s website.

The Importance of Sleep

It seems as if each day there is new information on sleep, its importance in our daily lives and the severe implications to our health if we don’t get enough. Sleep deprivation is now considered a widespread public health issue as one in five American adults show signs of it. While this news certainly impacts all people, it is of even greater significance to shift workers, who on average get less sleep.

A recent article in e! Science News talks about the October meeting of Neuroscience 2012 during which a number of new findings on sleep were revealed. One of the findings describes how sleep enables the remodeling of memories — including the weakening of irrelevant memories — and the coherent integration of old and new information.  Another shows that loss of less than half a night’s sleep can impair memory and alter the normal behavior of brain cells.

Dr. Clifford Saper, an expert on sleep and sleep deprivation who served as the press conference moderator, said “As these research findings show, we cannot underestimate the value of a good night’s sleep”. To learn more and read the article in its entirety, please click here..
