The Sleep-Sunrise Connection: Why Dawn Matters

Nature’s Alarm Clock

Morning sunlight contains unique blue light frequencies that trigger cortisol release at the ideal time, creating a 12-hour melatonin preparation period.

The Science of Solar Synchronization

Specialized eye cells detect sunrise light even through closed eyelids, setting your biological clock.

The 30-Lux Threshold

You need just 30 minutes of 30+ lux light exposure (equivalent to sunrise) for full circadian benefits.
