The Cortisol Sleep Method
Fix the hormone, keep the coffee, sleep like a kid again. 21 days. 14 minutes a morning.
The method
Cold shower · Sunlight · 4-min Tabata · Sunset · Blue light · Screen off · Fixed wake time.
That's it. Fits on a business card. 21 days to feel like you're 22 again.
"I slept 8 hours and woke up like a zombie. Tried melatonin, magnesium, quitting coffee — quitting made me more anxious. 21 days fixing my cortisol curve and now I sleep 7 hours and feel like I'm 22. I still drink coffee every morning."

Why this works
Your cortisol should spike HIGH in the morning and crash at night. Most people have a flat curve — tired all day, wired at 11pm. These protocols rebuild the curve.
Morning Protocol
Cold Shower
60 seconds minimum. As cold as it gets. Right after you wake up.
Why: Forces a natural cortisol spike at the right moment. Your body needs high cortisol in the morning — this gives it to you.
Sunlight on Face
10 min if sunny. 30 min if cloudy. Sunglasses off. Outside only.
Why: Triggers your suprachiasmatic nucleus — your master body clock. This sets the timer for melatonin release 14-16h later.
4-Minute Tabata
20 sec all-out, 10 sec rest. 8 rounds. Any exercise.
Why: Amplifies the morning cortisol peak. Tired at night = strong morning cortisol. Wired at night = flat morning cortisol.
Coffee Rule
Wait 90 minutes after waking before your first cup.
Let your natural cortisol peak finish. Then add caffeine on top of it, not instead of it.
Evening Protocol
Watch the Sunset
60 seconds outside, every day. Even through a window if necessary.
Your body has used sunset as the sleep trigger for 200,000 years. Don't skip it.
Blue Light Blockers On
After sunset. Amber glasses or app (f.lux, Night Shift, Twilight).
Screens Off
30-60 min before bed. Phone face-down. TV off. Not negotiable.
Fixed Wake Time
Same time every morning. Weekends too. Even if you slept badly.
This is the #1 variable. Consistency trains your cortisol curve faster than anything else.
Last coffee
Hard cutoff: noon.
Caffeine half-life is 5-7 hours. 2pm coffee = 25% still active at midnight.
Supplement Stack
The morning and evening protocols alone are enough. Supplements amplify. Start with the free protocol for 14 days first.
Magnesium Glycinate
400mg · 30 min before bed
Most people are magnesium deficient. This form is absorbed well, doesn't cause GI issues, and directly supports deep sleep and muscle recovery.
Protocol alone will give you 80% of the result. Add magnesium if you're still struggling at day 14.
