Circadian Rhythms

Circadian rhythms influence our body temperature, sleep, wakefulness, and various hormonal changes. Certain environmental cues help set our circadian cycles such as sunlight which help set a consistent cycle from day to day. Circadian rhythms are also known as the “internal body clock” that regulates the (approximately) 24-hour cycle.

Circadian rhythms are managed by small nuclei in the brain that controls many of the body’s functions. It is believed that light has the biggest impact on problems with circadian rhythms.

What causes circadian rhythm disorders?

To an extent, an individual’s circadian rhythm is determined by genetics. However, circadian rhythm disorders can be caused by many environmental factors, including:

  • jet lag
  • shift work
  • pregnancy
  • time zone changes
  • medications
  • changes in routine
