Sleep duration of five hours or less was associated with double the risk of dementia in older adults. Sleep disruptions also increased death risk in those in their seventies.
A lack of sufficient sleep led to a 9% increase in total abdominal fat and an 11% increase in visceral abdominal fat.
After just one sleep deprived night, the ability of the liver to produce glucose and insulin is altered, increasing the risk of developing metabolic diseases, such as type 2 diabetes, researchers report.
Increasing ambient temperatures has a negative impact on sleep duration, researchers report.
Following a night of sleep deprivations, levels of tau in the blood increase 17% in healthy young men.
Three consecutive nights of sleep loss can have a negative impact on both mental and physical health. Sleep deprivation can lead to an increase in anger, frustration, and anxiety. Additionally, those who experienced sleep loss reported a change in physical wellbeing, including gastrointestinal and respiratory problems.
A new study sheds light on numerous functions of our circadian clock, from how the brain maintains performance during the day to how shift workers struggle to maintain attention during early morning hours.
A new study reveals people are suffering dream deprivation as a result of being deprived of REM sleep. Researchers report dreams are essential for memory and mental health. Dream deprivation can lead to an increased risk of depression and illness.
Sleep deprivation results in a reduced ability to correctly read the emotional facial expressions of others, a new study reports.
Reductions in reaction time, memory, and other neuropsychological problems persist for at least seven days following a ten-day period of insufficient sleep.
