Circadian Rhythm Disorders

Circadian rhythms are the physical and mental changes that occur throughout the course of the day and affect whether you feel awake or sleepy.

They are your brain’s way of signaling your body to get ready to sleep at night and be awake in the daytime.

If the circadian rhythm doesn’t line up with the times you need to sleep (such as in shift work or jet lag) then you can feel tired when you want to be awake or vice versa.


Treatment for circadian rhythm disorders may include:

  • Gradually adjusting the time of sleep
  • Adjusting light exposure before bedtime and at wake time
  • Medication

Get Started

To see a sleep specialist, contact your physician and ask for a referral to OSF Sleep.

Once we have received the referral, we will contact you to schedule an appointment.
