A study indicated that sleep quality impacted women's mood and changed how they felt about advancing in their careers. Meanwhile, men's aspirations were not impacted by sleep quality. The researchers discovered this finding in a...
Oppressive, frightening, nerve-wracking: nightmares are particularly disturbing dreams. They are considered pathological when they occur frequently (>1 episode per week) and cause daytime fatigue, mood alteration and anxiety. Although...
A new study looks deep inside the brain, where previous learning was reactivated during sleep, resulting in improved memory. Neuroscientists teamed up with clinicians to study the brain electrical activity in five of the center's...
Why do some 4- and 5-year-olds still nap like clockwork every afternoon, while other preschoolers start giving up habitual napping at age 3? It's a question many parents no doubt ponder and one that a sleep scientist has been considering...
Using a neural network model, neuroscientists have found that, as the brain moves between REM and slow-wave sleep cycles, the hippocampus teaches the neocortex what it learned. This process seems to convert novel, fleeting data into...
Scientists have uncovered the mechanism behind why eating late at night is linked to weight gain and diabetes. The connection between eating time, sleep and obesity is well-known but poorly understood, with research showing that...
Researchers have evaluated an expanded measure of cardiovascular health (CVH) that includes sleep as an eighth metric, in relation to cardiovascular disease risk.
Getting less than five hours of sleep in mid-to-late life could be linked to an increased risk of developing at least two chronic diseases, finds a new study.
A team led by researchers has developed a powerful computational tool for understanding brain health and disease, providing an enhanced way of characterizing the activity of the brain during sleep.
Earlier elementary school day start times predict less sleep for students but have little to no effect on their educational outcomes, according to new research.
New research provides clues to falling fast asleep -- or lying wide awake. Studying fruit flies, researchers found that brain neurons adapt to help the flies stay awake despite tiredness in dangerous situations and help them fall asleep...
Some smart home technology could help curb opioid overdose. A pilot study showed that a set of noninvasive home sensors could provide accurate information about overnight restlessness and sleep problems for people recovering from opioid...
Acetaminophen use during pregnancy is associated with sleep and behavior problems consistent with attention deficit hyperactivity disorder (ADHD), according to a new study.
Researchers used accelerometers to study how the 24-hour movement behaviors, i.e. sleep, sedentary behavior, light physical activity and moderate-to-vigorous physical activity change in relation to each other when a person retires. The...
Chronic, insufficient sleep can negatively affect immune cells, which may lead to inflammatory disorders and cardiovascular disease, according to a new study. More specifically, consistently losing an hour and a half of sleep a night...
Are you an early bird or a night owl? Our activity patterns and sleep cycles could influence our risk of diseases, such as type 2 diabetes and heart disease. New research has found wake/sleep cycles cause metabolic differences and alter...
The study suggests a previously unobserved relationship between body temperature and REM sleep, with REM sleep appearing to act like a 'thermostatically controlled brain heater.'
A new national survey finds many Americans are losing sleep over stress and worry about the current state of the world. After a global pandemic, polarizing political division and more than two years of turbulent events, nearly one in...
Investigators have designed a study that simulated night work and then tested the effects of daytime and nighttime eating versus daytime eating only. The team found that, among participants in the daytime and nighttime eating group,...
A new study has found that older people with insomnia are at greater risk of developing memory decline and long-term cognitive impairment such as dementia.
Scientists hypothesize that circadian rhythm disruption is a psychopathology factor shared by a broad range of mental illnesses and that research into its molecular foundation could be key to unlocking better therapies and treatments.
Young people living with a genetic alteration that increases the risk of psychiatric disorders have markedly different brain activity during sleep, a new study shows.
The earlier individuals develop Type 2 diabetes or hypertension in life, the earlier they are likely to develop primary open-angle glaucoma (POAG), the leading cause of irreversible blindness worldwide, researchers report.
Nine in ten people do not get a good night's sleep, according to new research. The study found that suboptimal sleep was associated with a higher likelihood of heart disease and stroke. The authors estimated that seven in ten of these...
When our eyes move during REM sleep, we're gazing at things in the dream world our brains have created, according to a new study. The findings shed light not only into how we dream, but also into how our imaginations work.
Adolescents who sleep less than eight hours a night are more likely to be overweight or obese compared to their peers with sufficient sleep, according to new research. Shorter sleepers were also more likely to have a combination of other...
Lack of sleep is associated with increased risk of cardiovascular disease, depression, diabetes, hypertension and sexual dysfunction. A new study now shows that lack of sleep also affects social interactions, making people less willing...
Neurobiologists have found that fruit flies are pre-programmed to take a nap in the middle of the day. The new article explores a 'thermometer' circuit for hot temperatures.
The use of medication to treat sleep disturbances has fallen dramatically in the United States in recent years after several decades of climbing steeply, according to a new study.
Heavy drinkers with symptoms of insomnia, such as difficulty falling or staying asleep, may be less likely to suffer alcohol-induced blackouts, according to a new study.
Elementary school-age children who get less than nine hours of sleep per night have significant differences in certain brain regions responsible for memory, intelligence and well-being compared to those who get the recommended nine to 12...
Relapse presents a major barrier to recovery from substance use disorders -- when people begin taking drugs such as cocaine again after a period of abstinence. Sleep disruptions have long been associated with drug withdrawal and relapse....
A new study of student wellbeing during the pandemic has identified worsened financial situation and sleep difficulties as key indicators of individuals at higher risk of developing mental health issues.
Frequent or usual daytime napping in adults was associated with a 12% higher risk of developing high blood pressure and a 24% high risk of having a stroke compared to never napping. Experts say napping, though not unhealthy, may be a...
The transition to kindergarten is a notable milestone for children and families, who typically prepare by gathering school supplies and meeting the teacher. New research suggests that one important way to prepare for the transition to...
You may think that a good night's sleep should be uninterrupted. But in fact, the neurotransmitter noradrenaline causes you to wake up more than 100 times a night, new research concludes. It is perfectly normal and may even indicate that...
Scientists have discovered that brain inflammation may link Alzheimer's disease risk with sleep disturbance, which may aid early detection and prevention efforts by identifying novel treatment targets at preclinical stages.
As most Americans wind down for bed, 15 million people are just clocking into work. These hospital workers, emergency responders, factory operators and others are among the 20 percent of the world's population who do shift work. Their...
