Evidence Strength
5/5 — Very StrongVery strong evidence supports caffeine's wake-promoting effects and sleep-disruption potential. Keep public copy framed as a personal timing experiment because sensitivity, dose, and metabolism vary.
Overview
Test a personal caffeine cutoff at least 8-10 hours before your target bedtime. Caffeine sensitivity varies, so use this as a tracked experiment rather than a universal rule.
Wellness education and routine support only. Review the evidence, caveats, and interactions before trying this protocol, and ask a clinician when medical conditions, pregnancy, medications, or symptoms are involved.
How To Do It
- 1
Calculate your curfew
Subtract 8-10 hours from bedtime. For a 10pm bedtime, stop caffeine by noon-2pm.
- 2
Audit hidden caffeine
Watch for caffeine in tea, chocolate, pre-workout, and some medications.
- 3
Delay morning caffeine
Wait 90-120 min after waking for your first caffeine to avoid afternoon crash and dependence.
The Evidence
Each claim is linked to its source study. Confidence reflects the study design — systematic reviews and RCTs rank highest.
Caffeine effects on sleep taken 0, 3, or 6 hours before going to bed
Caffeine consumed even 6 hours before bedtime significantly disrupted sleep.

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.
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.
Glycine for Sleep Quality
Optional 3g bedtime glycine experiment with subjective sleep and next-day fatigue tracking; review caveats before adding it to a routine.
Consistent Wake Time
Set one wake time and stick to it 7 days/week. This anchors your entire circadian system more reliably than any other single habit.
