1. CBT-I (highest impact)
70 to 80 percent response rate, effects lasting years. The single most effective non-drug treatment. Available via therapists, apps (Sleepio, Somryst), and self-guided workbooks.
2. Sleep restriction
Compress time in bed to actual sleep time, build sleep pressure, then expand. Counterintuitive but the strongest single CBT-I lever. Visible change in 7 to 14 days.
3. Consistent wake time
Same wake time 7 days a week — within 30 minutes. Foundational; nothing else works reliably without it.
4. Morning bright light
10 to 30 minutes of outdoor light within 30 minutes of waking. Anchors circadian rhythm more powerfully than any pill.
5. Caffeine cutoff at noon
Caffeine has a 5 to 7 hour half-life. Afternoon coffee measurably reduces deep sleep even if you fall asleep fine.
6. Stimulus control
Bed only for sleep and intimacy. Out of bed after 20 minutes awake. Reverses the learned association between bed and arousal.
7. Wind-down routine
45 to 60 minutes of dim light, low-stimulation activity. Signals the nervous system to shift modes.
8. Cool bedroom
65 to 68 °F. Core temperature must drop 1 to 2 °F to initiate deep sleep.
9. Blackout and silence
Cannot see your hand in front of your face. Earplugs or white noise if street or partner noise intrudes.
10. Daily exercise
30 minutes most days, finishing 3+ hours before bed. Strongest non-CBT lifestyle predictor of sleep quality.
11. Magnesium glycinate
200 to 400 mg taken 60 minutes before bed. Modest but real evidence; well tolerated.
12. Breathing techniques
4-7-8 breathing or box breathing for 5 minutes at lights out. Activates parasympathetic recovery and shortens sleep onset latency by 20 to 40 percent in trials.
How to sequence them
Start with #3, #4, #5, #8, #9 — the environment and timing foundation. Add #6 and #7 in week 2. Add #2 (sleep restriction) only if symptoms persist after 3 weeks. Layer #11 and #12 anytime. Pursue #1 (CBT-I) if symptoms remain after 6 weeks.
FAQ
How long until I see change? Foundations: 7 to 14 days. CBT-I: 4 to 8 weeks. Do I need all 12? No — most people only need 4 to 6 to transform sleep. Do supplements replace these? No — they augment a working protocol, they do not substitute for one.
