Related Protocols
Morning Sunlight Exposure
Use outdoor morning light within 60 minutes of waking as a practical cue that may help anchor circadian timing and a consistent morning routine.
Blue Light Reduction
Dim lights and avoid screens 2-3 hours before bed to protect melatonin production. Use warm/amber lighting and blue-light blocking glasses if screen use is unavoidable.
Tart Cherry Juice for Sleep
Tart cherry juice is a natural source of melatonin and tryptophan-sparing compounds. Clinical trials show it increases sleep time by ~84 minutes in adults with insomnia.
Sleep Temperature Optimization
Try a cooler bedroom and a warm pre-bed shower as adjustable sleep-environment cues, then track comfort and sleep timing for a week.
