Optimizing the Circadian Rhythm

Our intrinsic body clock (circadian rhythm) regulates a complex series of rhythms in sleepiness and alertness. The individual period of the endogenous clock is usually ~24 hours and is normally assigned to match the times when the sun goes up and when the sun goes down (environmental rhythm). For the most part, our “body clocks” are internally generated, however, they can be modified by external cues such as sunlight and temperature. For example, making your bedroom cool, dark, and quiet (~60-65F) optimizes release of melatonin, the natural hormone that signals the body to go to sleep.
