Researchers presents a new study demonstrating that a small molecule in brain cells affects the level of hypocretin, which is responsible for making us feel awake during the day and tired at night. People with a genetic variation of this...
Seven hours is the ideal amount of sleep for people in their middle age and upwards, with too little or too much little sleep associated with poorer cognitive performance and mental health, say researchers.
Up to half of older adults may have sleep apnea, a condition in which breathing and sleep are briefly interrupted many times a night. A new study shows that this chronic tiredness can have serious implications for road safety.
Black women are disproportionately affected by poor sleep, which is associated with increased risk of adverse outcomes such as cardiovascular disease, depression and worse quality of life. The gold standard treatment for insomnia is...
A new study demonstrates that in utero exposure to mother's antiepileptic or antidepressant medication may affect development of the newborn brain networks. In the study, novel mathematical methods were developed to allow future research...
A new study has paved the way for the first drug treatment for sleep apnea. Compared to before receiving the treatment, breathing pauses decreased with on average more than 20 per hour for patients given the drug.
Researchers have developed a wearable device that plays specific sounds to enhance deep sleep. The first clinical study has now shown that the device is effective, but not at the same level of effectiveness for everyone.
Using data collected by the National Health Interview Survey from 2004 to 2018, researchers found that the proportion of people who reported sleeping fewer than seven hours per day increased significantly over the 15-year period, and it...
The lethargy that many Alzheimer's patients experience is caused not by a lack of sleep, but rather by the degeneration of a type of neuron that keeps us awake, according to a study that also confirms the tau protein is behind that...
A research group found that the human sleep patterns could be classified into 16 types by combining ACCEL, their original machine learning algorithm for sleep-wake classification, the dimension reduction method and the clustering method....
New research shows that lack of sufficient sleep combined with free access to food increases calorie consumption and consequently fat accumulation, especially unhealthy fat inside the belly.
Each person has their own individual sleep profile which can be identified by the electrical brain activity during sleep. Researchers have now demonstrated that the brain waves during periods of deep sleep in a specific area of the brain...
It's no secret that working nontraditional shifts can wreak havoc on lifestyle and sleep habits. Shift work has also been known to have a negative effect on workers' health. A new study suggests it also may delay the onset of natural...
A new report addresses the issue of exactly how bright lighting should be during the day and in the evening to support healthy body rhythms, restful sleep, and daytime alertness.
Some people are gifted with genes that pack the benefits of slumber into an efficient time window, keeping them peppy on only four or six hours of sleep a night. In addition, the scientists said, these 'elite sleepers' show psychological...
Exposure to even moderate ambient lighting during nighttime sleep, compared to sleeping in a dimly lit room, harms your cardiovascular function during sleep and increases your insulin resistance the following morning, reports a new...
Obstructive sleep apnea (OSA) affects 22 million people in the U.S. and is linked to a higher risk of hypertension, heart attacks, stroke, diabetes and many other chronic conditions. But now researchers have found that untreated OSA also...
UNLV-led research team identifies key brain protein to target for new customized drug therapies treating adverse symptoms of developmental disorder subtypes.
Children with insomnia symptoms are likely to persist with them as young adults and are significantly more likely to develop an insomnia disorder in early adulthood compared to children who do not have difficulty sleeping, according to...
The combination of mathematical modeling and experiments identifies the difference in molecular clockworks of the master and slave clock neurons in Drosophila. This solves the long-standing mystery of the molecular mechanisms underlying...
The brain's ability to clear a protein closely linked to Alzheimer's disease is tied to our circadian cycle, according to new research. The research underscores the importance of healthy sleep habits in preventing the protein...
Neuropeptides play fundamental roles in modulating cellular and circuit functions within the brain. One such signaling molecule -- orexin -- regulates arousal and wakefulness, and its failure can lead to constant daytime sleepiness...
New research has examined how sleep might be impacted by media use -- such as watching movies, television, or short videos; browsing the Internet; or listening to music -- before bed.
Individual aspects of poor sleep can be detrimental to heart health. But if you combine them, the risk of heart disease can increase by as much as 141 percent.

Nurses who work the night shift report more sleep disturbances and are more likely to suffer from psychological and physical health symptoms including PTSD, insomnia and inflammation, a recent study found.
Researchers found that a monkey's state of attentiveness may be encoded in the shapes and speeds of slow electrical waves that course over the surface of the brain. Like a surfer that avoids smooth water and favors more active waves, the...
More than half of nurses had difficulty sleeping during the first six months of the COVID-19 pandemic -- and getting less sleep increased their odds of experiencing anxiety and depression, according to a new study.
A new study of preschoolers finds that exposure to even very low intensities of light before bedtime can sharply reduce production of the sleep-promoting hormone melatonin, interfering with sleep. It suggests that young children are...
