The Science of Sleep
Circadian Rhythm
Your body’s internal clock regulates sleep-wake cycles over a 24-hour period. This biological clock is influenced by light exposure and helps determine when you feel alert or sleepy.
Key Fact: Melatonin production typically begins around 9 PM and peaks between 2-4 AM.
Sleep Architecture
Sleep occurs in cycles of 90-120 minutes, progressing through different stages. Each stage serves specific functions for physical and mental restoration.
Research Shows: Adults need 4-6 complete sleep cycles per night for optimal recovery.
