Every cell in your body keeps time. Aligning your day with your circadian rhythm improves sleep, energy, and long-term metabolic health.
Morning light
10 minutes of outdoor light within an hour of waking sets the day. It locks the rhythm and improves nighttime melatonin release.
Eat with the sun
A larger breakfast and lunch, lighter dinner. Eating late blunts insulin sensitivity and disrupts sleep architecture.
Move during the day
Daytime movement deepens nighttime sleep. Evening exercise is fine if done at least 2 hours before bed.
Protect the dark
The body needs both bright days and dark nights. Dimming the evening is as important as brightening the morning.
