How to Build a Sleep Routine That Works for Your Circadian Rhythm

The Science Behind Sleep Routines

Your circadian rhythm governs your sleep-wake cycle, and consistency is key to optimizing it. Research from the National Sleep Foundation shows that irregular bedtimes can disrupt melatonin production by up to 40%.

Why Your Body Craves Consistency

The Role of Melatonin

This sleep hormone follows a strict schedule. Going to bed at the same time nightly trains your brain to release it predictably.

Deep Sleep Optimization

Studies indicate consistent sleepers spend 20% more time in restorative Stage 3 sleep compared to those with erratic schedules.

Creating Your Ideal Schedule

Finding Your Natural Window

Track your energy dips for 3 nights to identify when your body naturally winds down.

The 90-Minute Rule

Time bedtime to complete 5-6 full sleep cycles (each lasting 90 minutes) before your alarm.
