Reportedly, the ideal amount of hours one should sleep is seven. While sleeping too little "impairs performance and memory the next day," too much sleep is associated with "diabetes, obesity and cardiovascular disease and with higher rates of death, studies show."
Several sleep studies have found that seven hours is the optimal amount of sleep—not eight, as was long believed—when it comes to certain cognitive and health markers, although many doctors question that conclusion.
[...] "The lowest mortality and morbidity is with seven hours," said Shawn Youngstedt, a professor in the College of Nursing and Health Innovation at Arizona State University Phoenix. "Eight hours or more has consistently been shown to be hazardous," says Dr. Youngstedt, who researches the effects of oversleeping.
