Circadian rhythm is your body’s natural, internal 24-hour cycle that determines when you sleep and eat, your body temperature and when crucial hormones are released. This body clock is regulated ...

New research suggests that the circadian system in people with obstructive sleep apnea may disrupt blood vessel function overnight, which may help explain the higher risk of nighttime heart attacks in ...

Yes, it’s that time of year again, when most of the U.S. “gains” an extra hour of sleep as we “fall back” from daylight savings to shorter days, colder nights, and standard time. This Sunday, November ...
