How Much Sleep Do You Actually Need
The ideal amount of sleep for humans is seven to eight hours per night, according to most studies, with less than seven hours leading to an increased risk of heart disease, obesity and diabetes, and more than eight hours increasing the risk of heart disease, obesity, diabetes and an increased risk of mortality. Genetics play a big role in how much sleep an individual needs, with some people unaffected by only six hours of sleep, however, sleep debt after long-term deprivation can cause a slower recovery of cognitive function.
