It’s well known that getting enough sleep is critical to daily functioning and long-term health. Now, new research suggests that a lack of enough REM sleep may be related to earlier death in people at middle age or older.
The body’s circadian rhythm controls our sleep-wake cycle, so an irregular rhythm can negatively affect sleep and proper functioning, which can lead to health problems including mood disorders. The tendency to rise early or stay up late is genetically determined, but you may be able to adjust your life to better match your circadian rhythm.
