The Centers for Disease Control and Prevention, which requested and helped support the development of the current recommendations, has called not getting enough sleep a public health epidemic
For many aspects of health, "it was quite clear that seven to nine hours was good," said Dr. Nathaniel F. Watson, president of the American Academy of Sleep Medicine and a professor of neurology at University of Washington. Watson led the panel of experts that wrote the recommendations. The group looked at more than 300 studies.
Getting only six hours of sleep a night or less was associated with setbacks in performance, including mental alertness and driving ability, and increased risk of heart attack, stroke, diabetes and obesity, Watson said.
