Fix your sleep with morning sunlight
A simple system that gets you outside after waking up.
15 minutes outside. No motivation needed. Designed for real mornings.

Mornings aren't the problem. Light is.
Indoor lighting and screens don't deliver the signal your brain expects after waking. Without real morning light, your circadian rhythm drifts — affecting energy, focus, mood, and sleep.
Your brain runs on light, not willpower
Morning light triggers cortisol for alertness
It starts a ~16-hour timer for melatonin at night
Consistent exposure improves mood and stress resilience
Timing and consistency matter more than intensity.
