Researchers conducted an experiment on the nature of sleep in an evacuation shelter environment. This experiment was performed by creating a mock shelter in the university's gymnasium with four of the emergency blankets as well as a...
A new study has found that first exposure earlier than 18 months of age to screen devices -- such as smartphones, tablets, videogame consoles, television etc -- and the presence of multiple screen devices in the bedroom are associated...
If you have trouble sleeping, you're not alone. New research finds more Americans have trouble falling asleep and staying asleep. The difficulties were most prevalent in people with healthy sleep length.
A new study of mice has shown how stress hormones control fat and sugar levels in a time dependent way and how a high calorie diet can alter this rhythm.
Researchers have shown how the brain's circadian rhythm in rats is, among other things, controlled by the stress hormone corticosterone -- in humans called cortisol. This has been shown by means of a completely new method in the form of...
People who have trouble sleeping may be more likely to have a stroke, heart attack or other cerebrovascular or cardiovascular diseases, according to a new study.
The annual transition to and from daylight saving time (DST) has clinical implications that last longer than the days where clocks 'fall back' or 'spring forward.'
Researchers have found that the type of sleep most apt to calm and reset the anxious brain is deep sleep, also known as non-rapid eye movement (NREM) slow-wave sleep, a state in which neural oscillations become highly synchronized, and...
Several things can cause headaches at night. Read this article to learn more about the conditions associated with nighttime headaches, as well as how to treat them.
People may sometimes experience muscle soreness during or after exercise. Read on to find out the causes of this muscle soreness and how to continue working out when feeling sore.
Nocturnal seizures occur when a person is asleep. As well as typical seizure symptoms, they may increase the risk of other complications. Learn more in this article.
A new study illustrates that the brain's cerebrospinal fluid pulses during sleep, and that these motions are closely tied with brain wave activity and blood flow. It may confirm the hypothesis that CSF flow and slow-wave activity both...
As if you didn't already have enough to worry about to keep you up at night, a new study indicates that poor sleep can negatively affect your gut microbiome, which can, in turn, lead to additional health issues.
Excessive sleepiness often occurs following a poor night's sleep. In some cases, it may be a symptom of a sleep disorder or another underlying health condition. Read on to discover the causes of excessive sleepiness, as well as their...
The best nap duration varies from person to person, but experts tend to agree that 20 minutes is ideal. Learn more about how long naps should be in this article.
Only 48% of school age children in the United States get 9 hours of sleep most weeknights, according to new research. Those who do, the study suggests, are significantly more likely to show a positive outlook toward school and other...
Researchers have identified 57 genetic variations of a gene strongly associated with declines in blood oxygen levels during sleep. Low oxygen levels during sleep are a clinical indicator of the severity of sleep apnea, a disorder that...
Research in mice suggests that the brain's dedicated immune cells are better able to do repair work during sleep, and explains the underlying mechanism.
Science tells us that a lot of good things happen in our brains while we sleep -- learning and memories are consolidated and waste is removed, among other things. New research shows for the first time that important immune cells called...
Scientists have shown that delta waves emitted while we sleep are not generalized periods of silence during which the cortex rests, as has been described for decades in the scientific literature. Instead, they isolate assemblies of...
Military veterans with post-traumatic stress disorder or concussion suffer from a thrashing form of sleep behavior at a rate that is far higher than the general population, according to a new study. Researchers next want to probe whether...
Distinct patterns of electrical activity in the sleeping brain may influence whether we remember or forget what we learned the previous day, according to a new study. The scientists were able to influence how well rats learned a new...
Severe and persistent infant sleep problems in the first year are linked to poor maternal mental and physical health during pregnancy, a new study has found.
Many women have concerns about how to sleep when pregnant. Pregnancy can cause difficulty sleeping, and certain sleeping positions are safer than others. Learn how to sleep when pregnant here, including what positions to try or avoid.
Middle-aged adults with high blood pressure, Type 2 diabetes, heart disease or stroke could be at increased risk for cancer and early death when sleeping less than 6 hours per day.
Two professors have found a strong relationship between students' grades and how much sleep they're getting. What time students go to bed and the consistency of their sleep habits also make a big difference. And no, getting a good...
Insomnia is a driver of suicide, and particularly people with severe insomnia may safely benefit from taking a sedative to help address their sleep problems as it reduces their suicidal thoughts, investigators report.
In an exceptionally extensive worldwide study on sleep, nearly a quarter of a million nights of sleep were measured among sleepers ranging between 16 and 30 years of age.
Although coffee’s caffeine content makes it a stimulant, some people feel tired after they drink a cup. Learn about why coffee could make a person feel tired here.
Teenagers got 43 more minutes of sleep a night after a four-week intervention that reset their body clocks and helped them go to bed earlier, a study has shown.
The biological clock influences immune response efficacy. Indeed, CD8 T cells, which are essential to fight infections and cancers, function very differently according to the time of day.
Investigators report that a single-session sleep education program for survivors can cure insomnia in many participants, and that those who don't benefit from this approach are often helped by a more extensive, but still modest,...
Experts frequently tout the value of a good night's sleep. However, a new study casts doubt on the value of sleep time suggesting that women who experience night sweats are more vulnerable to cognitive dysfunction as their sleep duration...
Many people reach a weight loss plateau after several months of diet and exercise. In this article, learn about the possible causes and what to do to break through the plateau.
New research in mice singles out a group of neurons that may be responsible for our forgetting unnecessary information during the dreaming stage of sleep.
In a study of mice, researchers show that REM sleep may be a time when the brain actively forgets. Their results suggest that forgetting during sleep may be controlled by neurons found deep inside the brain that were previously known for...
