Sleep Circadian Rhythm

Circadian rhythm is basically a 24-hour internal clock that is running in the background of your brain and cycles between sleepiness and alertness at regular intervals. It’s also known as your sleep/wake cycle. It’s the feeling you get when you are energized and drowsy around the same times every day and can be caused by shift work, time zone changes, medical problems such as pregnancy and mental health problems.

Other Issues

Circadian Rhythms may lead to sleep disorders, depression, bipolar disorder, or eating and digestion habits.


  • You have a hard time initiating sleep.
  • You struggle to maintain sleep, waking up frequently during the night.
  • You tend to wake up too early and unable to go back to sleep.
  • Your sleep is non-restorative or of poor quality.


Possible treatments for Circadian Rhythm sleep disorder include:

  • Modifications to your sleep environment or sleep routines.
  • Medications or dietary supplements
  • Bright light therapy to advance or delay sleep
  • Sleep phase chronotherapy to progressively advance or delay the sleep time by 1-2 hours per day.
