Is 5 Hours Enough Sleep?
Research by Dr. Daniel F. Kripke, a professor of psychiatry who focuses on sleep research and aging, revealed no significant health reason to sleep beyond six and a half hours nightly. His findings leveraged data from the Cancer Prevention Study II (CPS-II) by the American Cancer Society suggesting that sleeping around five hours each night is marginally safer than eight.
The study, conducted from 1982-1988, gathered sleeping pattern data and other relevant details from approximately 1.1 million participants. The research is notable and widely respected due to its extensive analysis over a considerable duration. One key discovery is that a minimum of five hours of sleep each night may be more beneficial than eight hours or more.
