If you think your prescription medication is making you sleepy, talk with your doctor before you stop taking it. Aging Today’s society often doesn’t allow for this type of flexibility, thus we have to conform to today’s sleep/wake schedules. It is generally thought a continuous seven to nine-hour unbroken sleep is probably best for feeling refreshed. Such a schedule may not suit our circadian rhythms, however, as we desynchronize with the external 24-hour light/dark cycle. Go to sleep and wake up at the same time every day, even on the weekends. When you go to bed and wake up at the same time each day, you condition your body to expect sleep during that time. You may eventually get into a rhythm where sleep comes more easily. 2. Create an ideal sleep environment

Gottlieb DJ, et al. (2018). Sleep deficiency and motor vehicle crash risk in the general population: a prospective cohort study. As artificial lighting became more common, humans adopted a monophasic sleep schedule. Since then, we have considered ourselves unique among animals for sleeping in a single stretch at night, but we may not be monophasic sleepers after all, according to some research. Over the course of one experiment, participants naturally shifted to a biphasic sleep schedule when placed in a setting with less light than the average day provided.

View Source of cardiovascular disease, obesity, hypertension, and diabetes. Limit Your Light Exposure Some people intentionally adopt a polyphasic sleep schedule in hopes of becoming more productive. For most people, however, following a polyphasic sleep schedule — particularly one that reduces your total sleep time — leads to sleep deprivation and its associated negative physical and mental health outcomes. Even if artificial lighting was not fully to blame, by the end of the 20th Century, the division between the two sleeps had completely disappeared – the Industrial Revolution hadn't just changed our technology, but our biology, too.

Computer and phone screens emit what is called blue light. At night this kind of light can disrupt your body’s natural circadian rhythm and disrupt sleep. Power down your devices and limit your exposure to blue light in the two to three hours before bed. 4. Mind your lifestyle habits Some people find that biphasic sleep feels natural and works great for them, while others feel better on a monophasic sleep schedule. Either way, Jane's mother didn't get to keep her promise – she never returned home. That night, Mrs Rowth was brutally murdered, and her body was discovered in the following days. The crime was never solved. Our current monophasic sleep patterns might come with disadvantages. Exposure to more artificial lightFor treatment, doctors often prescribe medications similar to what is prescribed for narcolepsy. These medications may not treat idiopathic hypersomnia as effectively as they treat narcolepsy, however. Additionally, if you have idiopathic hypersomnia, you may need to make lifestyle changes such as limiting alcohol and avoiding late-night activities. Depression and Anxiety Sleep deprivation can result from poor sleep quality and insufficient sleep overall. Chronic sleep deprivation can increase your risk for serious health problems

Stage 1 (NREM). Stage 1, called N1, is the lightest stage of sleep and lasts for about 1 to 5 minutes. Your brainwaves, breathing, and heart rate all begin to slow, and your muscles relax. Try to limit the number of pets or children sleeping in your bed, and avoid falling asleep with the television on, even if the sound is off. And consider switching your pillow or mattress if they are uncomfortable. Originally, Ekirch had been researching a book about the history of night-time, and at the time he had been looking through records that spanned the era between the early Middle Ages and the Industrial Revolution. He was dreading writing the chapter on sleep, thinking that it was not only a universal necessity – but a biological constant. He was sceptical that he'd find anything new. There are actually two main types of sleep apnea. They can both cause excessive sleepiness because they keep you from getting enough deep sleep during the night. These types of sleep apnea are: Treating depression can be done with a combination of therapy, medications, and lifestyle changes. Antidepressant drugs aren’t always necessary. If your doctor recommends them, they may be needed temporarily.

Stage 2 (NREM). In stage 2, which is called N2, your body temperature drops while your heart rate and breathing continue to slow. Stage 2 lasts for about 25 minutes in your first sleep cycle and gets longer with each additional cycle.

Restless legs syndrome (RLS) causes an irresistible and uncomfortable urge to move your legs. You may be lying down peacefully when you start to feel a throbbing or itching sensation in your legs that only gets better when you get up and walk. RLS makes it difficult to fall asleep, resulting in excessive sleepiness the next day. MedlinePlus: National Library of Medicine (US). (2014, April 14). Healthy Sleep., Retrieved May 9, 2021, from In addition to the physical consequences, sleep deprivation impairs cognitive performance. Studies of preschool-aged children have found that daytime napping reduces attention span Hirskhkowitz, M. et al. (2015, January 14). National Sleep Foundation’s sleep time duration recommendations: methodology and results summary. Sleep Health, 1(1), 40-43 The exact amount of sleep you need each night depends on your daytime habits and activities, health, and sleep patterns. Older adults may need only six hours of sleep while other people, such as athletes, may need an extra hour of sleep. Occasionally you may require more sleep than normal, such as after strenuous activity or travel. If another hour of shuteye helps you feel your best, then that amount of sleep is right for your body. If consistently sleeping longer still leaves you tired or even nodding off during the day, it may be a sign of an underlying health issue. Oversleeping SymptomsBoth short and long sleep durations are associated with a number of health concerns and chronic diseases: It took some time for their sleep to regulate but by the fourth week, a distinct two-phase sleep pattern emerged. They slept first for four hours, then woke for one to three hours before falling into a second four-hour sleep. This finding suggests bi-phasic sleep is a natural process with a biological basis. Pros and cons Biphasic sleep is a sleep pattern in which a person splits their sleep into two main segments per day. They may sleep longer at night, and then take a nap during the day. Or, they may split their nighttime sleep up into two segments. Biphasic sleep is also referred to as segmented or bimodal sleep. Sleep apnea is a potentially serious condition in which you repeatedly stop and start breathing throughout the night. It can leave you feeling sleepy during the day.
