What Is the Circadian Rhythm?

Often referred to as the "body clock", the circadian rhythm is a cycle that tells our bodies when to sleep, rise, eat--regulating many physiological processes. This internal body clock is affected by environmental cues, like sunlight and temperature. When one's circadian rhythm is disrupted, sleeping and eating patterns can run amok. A growing body of research is examining the adverse health effects a disrupted circadian rhythm can have, like increasing the chances of cardiovascular events, obesity, and a correlation with neurological problems like depression and bipolar disorder.
