What is the Origin of Sleep Cycle Hygiene?

This term originated in the field of sleep medicine and behavioral therapy, gaining prominence as a foundational, non-pharmacological approach to treating insomnia and other sleep disorders. The term hygiene is used in the sense of practices conducive to health, drawing a parallel to personal cleanliness. The clinical focus on behavior modification has proven highly effective for chronic sleep issues.

What is the Mechanism of Sleep Cycle Hygiene?

The mechanism operates by reinforcing the body's endogenous circadian clock and maximizing the physiological drive for sleep. Maintaining a regular sleep-wake schedule stabilizes the master clock in the suprachiasmatic nucleus (SCN), ensuring the timely release of sleep-promoting hormones like melatonin. Creating a cool, dark, and quiet sleep environment optimizes the conditions for the body to enter and progress through the deep, restorative stages of non-REM and REM sleep, which are critical for metabolic and cognitive health.
