Researchers investigate the molecular mechanisms underpinning sleep.
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.
According to a new study, a lack of REM sleep can have negative implications on how we judge other people's facial expressions.
New mothers who sleep less than seven hours a night six months after giving birth had an increase in biological age of between three to seven years compared to new moms who slept for seven or more hours.
Daydreaming and mind-wandering appear to occur when parts of the brain fall asleep while other areas remain awake.
