What are Circadian Rhythm Sleep Disorders

1-800-MORE-SLEEP™

 

Circadian Rhythm Sleep Disorders involve a problem in a person’s “internal clock” or circadian rhythm that results in difficulty sleeping.  Your internal circadian clock runs on a 24 hour cycle, and regulates hormone production, digestion and, of course, sleeping.  Circadian Rhythm Sleep Disorders are characterized by a hard time initiating sleep, a struggle to maintain sleep, waking up early and being unable to fall back asleep, and non-restorative or poor quality sleep. There are many types of Circadian Rhythm Disorders, which are outlined below:

  • Delayed Sleep Phase Disorder (DSP): DSP is a sleep schedule problem that is typified by staying up and waking up later than is normal. Adolescents are often affected by DSP and have difficulty waking up for school or work as a result of it. 
  • Advanced Sleep Phase Disorder (ASP): ASP is a sleep schedule problem that involves going to sleep and waking up much earlier than is normal.  ASP typically affects older people and usually results in falling asleep between the hours of 6 and 9 p.m. and waking up between 2 and 5 a.m.
  • Jet Lag Disorder: Jet Lag Disorder occurs after a person travels across time zones.  There is a contrast between the actual time of day in their new location, and their internal clock.  This results in excessive sleepiness. 
  • Shift Work Disorder: Shift Work Disorder occurs when a person is scheduled to work during normal sleep hours.  This interrupts the circadian rhythm and makes them sleepy during their work shift.  People with Shift Work Disorder may also have difficulty falling asleep because they are forced to rest when most other people are awake. 
  • Irregular Sleep-Wake Rhythm: people who do not have a regular sleep pattern of any kind may suffer from Irregular Sleep-Wake Rhythm.  This occurs when a person naps periodically throughout the day and does not ever sleep for a prolonged period of time.
