Sleep News and Research

RSS

Sleep is a physiological behavior that is common in all animal species. It forms around one third of a human life. It is not known clearly the exact functions of sleep but it seems to be essential for survival as prolonged sleep deprivation leads to severe physical impairment followed by cognitive loss and eventually death.

Mitochondria of diabetic patients can't keep track of time, study finds

Almost all cells regulate their biological processes over a 24-hour period, otherwise called a cell's circadian rhythm. To do so, cells use a biological clock that cycles different genes on and off throughout the day and night.
