Whether you are a student, athlete, or just trying to live a healthy life, we could all benefit from a routine of adequate sleep. However, according to the Centers for Disease Control and Prevention, 1 in 3 American adults get less than seven hours per day, which is the recommended amount to maximize wellness. William Dement, M.D. argues in his book, The Promise of Sleep, that our patterns of rest are the single most important determinant of our length of life. But what is a “healthy” sleep schedule? It turns out that while inadequate sleep is common in the US, there can indeed be too much.
The National Sleep Foundation (NSF) has recommendations depending on your age group. The average for adults is 7-9 hours. As you get older, they recommend a shorter amount of time needed for sleep each night. However, they urge each person to reflect on how they feel each day and adjust their habits accordingly.
If you are one of the 33% of Americans not getting enough sleep you have probably tried or are willing to try anything to avoid staring at the ceiling for hours before falling asleep. For these unfortunate people, the moment the lights go off, their brain switches on…tossing and turning, wrestling and twitching until they reach exhaustion. One new product that has been receiving plenty of attention is a weighted blanket.
While sleeping with a weighted blanket may seem a little extreme at first, many believe that sleeping with the equivalent of a 30 pound toddler evenly distributed across their body, is very effective in calming anxiety, promoting relaxation and sleep.
A weighted blanket is filled with plastic pellets or glass beads that add weight to the blanket. These blankets range in weight from five to 30 pounds. The sensation is similar to the lead vest worn during dental x-rays and the extra weight provides deep pressure to relieve anxiety and reduce insomnia.
Choosing the optimal weight or type of blanket is not an exact science. Manufacturers recommend adults use a blanket that is equal to 10% of their body weight. The filler determines the thickness and texture. Glass beads are smaller and produce a thinner blanket as compared to plastic pellets.
For those concerned with temperature, some blankets use bamboo as a cover for cooling, while others offer additional filling for warmth.
The theory behind the use of weighted blankets for anxiety and insomnia rests on previous research related to deep pressure stimulation…gentle pressure applied over the entire body (like being wrapped in a swaddle or sharing a prolonged hug).
The concept of deep pressure for stress and anxiety reduction is not entirely new. Occupational therapists working with children with autism spectrum disorders have used deep pressure to promote a calming and relaxing effect.
Research supporting the efficacy of weighted blankets is limited and varied. While some studies suggest weighted blankets offer promise for those suffering from anxiety, far less support their effectiveness for insomnia.
One study of 32 adult volunteers, reported 63% lower levels of anxiety after lying under a 30 pound blanket for 5 minutes. In another study, 30 participants who were hospitalized for a mental health crisis demonstrated 60% reduction in anxiety after using the blanket.

It may be too early to tell according to the scientific literature. However, there is some indication that weighted blankets may reduce anxiety in some. It is less certain that these blankets will reduce insomnia. There are no studies that indicate that weighted blankets are harmful and may be worth a try for those who have exhausted more traditional options for anxiety and insomnia as a replacement or adjunct.

Difficulty sleeping during the COVID-19 quarantine has become a common problem and can be manifested in a variety of ways; insomnia, fragmented sleep and nightmares. National prescription providers have reported a 21% increase in anti-insomnia, anti-anxiety and antidepressant medications since March of 2020. The past two weeks in Health & Exercise Forum” have been dedicated to sleep wellness.
We discussed the importance of sleep for health and wellness. Sleep is crucial to us as a species, but it is not always easily attained. For many individuals across the globe, sleeping properly can be a challenge. The trial and tribulations of the human experience can lead to restless nights and early morning risings without adequate sleep. This week, we will discuss how lack of quality or quantity of sleep can impact our lives in many ways and make suggestions to improve your sleep hygiene.
Although it may be tempting to sleep in on weekends after a long week of classes, some studies report that this habit results in a smaller volume of the gray matter of the brain in adolescents. Also, in this report, students who altered their sleep pattern on weekends had a lower grade average than those who did not. Therefore, it seems that it is not only important to maintain an average healthy average amount of sleep each night, but also to stay consistent with the hours that you are asleep.
There are many studies that have linked unhealthy sleep patterns to obesity. Inadequate sleep causes irregular levels of the hormones that are responsible for telling our brains when we need to eat. Therefore, this hormone imbalance can lead to obesity and thus make us vulnerable to the dangerous effects dramatically increased body fat.
A healthy sleep schedule has been shown to reduce the risk of heart disease and stroke, which are two of the leading causes of death in the United States. For example, interruptions in sleep due to disorders like sleep apnea have been shown to be a risk factor for stroke and that persistent tiredness often preceded heart disease.
Whether you are a high school or collegiate athlete, or simply enjoy some daily exercise, a healthy sleep schedule can help maximize performance. It is worth noting that it is possible that athletes require different sleep patterns than the general population to reach peak performance. Moreover, it has been shown that sleep loss is linked to a decreased ability in athletes to store sugar in the muscle to use as energy during a workout.
Needless to say, there are a plethora of things that can negatively impact our sleep. Even one night of poor sleep can drastically impact our performance and ability to concentrate the following day. So how do we combat this? There are several simple habits that can improve sleep hygiene and increase the likelihood of getting a good night’s sleep.
There are thousands of other resources that can help us achieve a great night’s sleep. Apps like “Calm” and “Headspace” have guided meditations and relaxation techniques to help us unwind before bed. More useful information about healthy sleep and why it is important can be found on Harvard Medical School’s Healthy Sleep website. And there are hundreds of thousands of YouTube videos with relaxation techniques and informative healthy sleep videos to be discovered. If these interventions do not improve your sleep, talk to your primary care doctor and see which next steps are right for you.
Sleeping well is not always easy and there will undoubtedly be nights on which rest eludes us despite our best efforts. But with consistent healthy sleep habits, we will be on our way to a healthier and better tomorrow.

We do it every night, hopefully. Children are doing it. Our grandparents are doing it. Teenagers do it all the time. We sleep of course. These hours in which we slumber are vital to our ability to function during the day and to our health overall. It does not appear evolutionarily advantageous for us to be unconscious for extended periods of time. Modern science tells us that much of our body’s restoration, strengthening, and processing occurs while we sleep. Our brains consolidate the information they have learned throughout the day and enhance our memory. Additionally, sleep restores sugar storage in our brains and improves the functioning of our immune system. But science does not illuminate why we need such a prolonged period other than the fact that we just seem to get sleepy after a long day.
Sleep is crucial to us as a species, but it is not always easily attained. For many individuals across the globe, this author included, sleeping properly can be a challenge. The trial and tribulations of the human experience can lead to restless nights and early morning risings without adequate sleep. But what is considered “adequate” sleep? The answer depends on your age. As we grow older, our sleeping requirements change drastically from infancy to elderdom. Infants are learning and processing so much information of this new world they now inhabit. Thus, their brains need enough time to analyze and consolidate the data, necessitating 12 to 15 hours of sleep. As we advance into adulthood, our sleep requirements drop to approximately 7 to 9 hours with some variability from person to person. Good indications of a restful night’s sleep include waking up feeling refreshed, functioning with enough energy for your daily tasks, and having continuous sleep- meaning there are not extended periods of time of wakefulness when we are supposed to be sleeping.
This seems easy enough to say, but significantly more difficult to do. Current reports demonstrate that roughly 100 million people suffer from insomnia at some point each year, with 25% progressing to long-term chronic sleep insufficiency. Insomnia is described as difficulty falling asleep or staying asleep for three nights per week for at least two consecutive weeks in a three-month period. There are a lot of unhealthy sleeping habits permeating the country. We measure the quality of sleep in two different dimensions duration (quantity) and depth (quality). The duration is straightforward enough. Do you sleep for the recommended 7 to 9 hours per night? The quality is a little more difficult to quantitate. Some individuals may sleep for the proper duration of time, but the depth is not adequate. Sleep quality is determined by the number of arousals or awakenings in a given night. As few as 5 arousals in a night can result in daytime sleepiness and performance deficits. In addition, how long we remain in certain phases of sleep also determines the quality of our sleep. There are four stages of sleep: N1, N2, N3, and REM with N3 being the most restful of the stages. When we fall asleep, we go through a predictable descent into sleep. We repeat the cycle of N1 to N2 to N3 to REM sleep every 60 to 90 minutes. The more time we remain in the restful stages, N3 and REM, the better our sleep is. As we age, we inevitably spend less and less time in restful sleep.
There are many factors that influence how we sleep. Everything from what we drink to the type of curtains we have can impact those crucial hours of sleep. Some of the more common culprits that disrupt our sleep are:
