The perfect morning routine, according to neuroscience.
Get bright light in your eyes within 30 minutes of waking, delay caffeine by ~90 minutes, schedule hard work for the cortisol peak, and finish the morning with a short cold exposure. Simple inputs, compounding effect on sleep and focus.
Key takeaways
- Morning sunlight exposure (2–10 min) anchors circadian rhythm and improves sleep onset that evening.
- Cortisol peaks within an hour of waking — align hard cognitive work with this window.
- Caffeine delayed 90–120 minutes after waking avoids an afternoon adenosine rebound.
- Cold exposure (60–90 s) after morning sun reinforces alertness via noradrenaline.
