Research: Circadian Rhythms

Circadian Rhythm – Part 1

Circadian rhythm also referred to as the “internal body clock,” regulates biological processes in a 24-hour period.   This internal clock is in sync with light-dark cycle over 24 hours.  The circadian rhythm is a cycle that tells our bodies when to eat, sleep and wake up.  Your biological clock is in the hypothalamus region of the basal forebrain.  Circadian rhythm affects mood, blood pressure, temperature, hormones, memory, metabolism, cognition, sleep, wakefulness, energy levels, the liver, the adrenals and leptin receptors.   When it is out of sync, it causes disruptions of body systems, chronic illness, aging, depression, and anxiety.  Current research is examining the health effects a disrupted circadian rhythm can have, like an increase in cardiovascular issues, obesity and neurological issues like bipolar disorder and depression.
