Long Naps Linked to Diabetes

A nap, a siesta, or as the Chinese call it, a wujiao, is a pleasant break from the day, but the debate on its health effects continues. While some studies have found cognitive benefits from a short afternoon sleep, others have suggested a link between napping and negative effects, including a shortened life span.

Now, a new study has found that people who nap longer than others are at higher risk for diabetes, suggesting that naps of different durations affect the body differently.
