Cortisol peaks at dawn. If you're scrolling in bed, you're starting your day already stressed...
Cortisol follows a precise circadian rhythm: it peaks 30 minutes after waking to give you alertness and energy, then tapers through the day, reaching its lowest point around 10pm. Morning sunlight exposure (10-30 minutes) anchors this rhythm. Evening blue light from screens suppresses melatonin and shifts the entire hormone cycle forward.
Five consistent days of proper light exposure produces measurable hormonal improvement.
Your cortisol is not random.
It peaks 30 minutes after you wake up — designed to mobilize energy for the day.
Then it falls steadily until near-zero at 10pm when melatonin rises.
If you scroll in bed at night, you flood your eyes with blue light, suppress melatonin, and push the entire cycle forward.
You start the next day cortisol-depleted.
Ten to thirty minutes of morning sunlight locks the rhythm.
No phone.
Just daylight.
Five days.
