Abstract
Circadian rhythm sleep disorders are classified into six subtypes.
- The subtypes include delayed sleep-phase disorder, advanced sleep-phase disorder, irregular sleep-wake rhythm, free-running disorder, jet-lag, and shift work disorder.
- Administering light and/or melatonin at specific times may effectively treat most circadian rhythm sleep disorders.
- The effects of these interventions are documented as good, although further well-controlled studies with long-term follow-up are needed.
- Light and melatonin treatments can be easily administered by physicians.
