6 Circadian Rhythm Sleep Disorders that May Be Disrupting Your Sleep

Posted by Jennifer Hines on Aug 25, 2018 4:54:00 PM

Your circadian rhythm is an ingrained biological clock that regulates the timing periods of tiredness and wakefulness throughout the day. Your body clock is calibrated by the appearance and disappearance of natural light in a 24-hour period. The term circadian is derived from the Latin "circa diem" meaning "approximately a day."

The functions of your circadian rhythm are based in the part of the brain known as the hypothalamus. Within the hypothalamus are a group of cells known as the suprachiasmatic nucleus (SCN), which is connected to our optic nerves that sense changes in light.
