How Much Sleep Do We Need?

Turns out the answer to this seemingly simple question might be a little surprising. A study done by Daniel Kripke in 2002 compared death rates among more than one million American adults who reported their nightly average amount of sleep. According to the study, people who sleep between 6.5 and 7.5 hours per night live the longest. People who sleep 8 hours or more, or less than 6.5 hours, don’t live quite as long. Even more interesting is the fact that sleeping ‘short’ – 5 hours or less – might be better than sleeping 8.5 hours or more. According to the article, this data has since been corroborated by similar studies in Europe and East Asia.
