What is melatonin?
Melatonin is a hormone produced by the pineal gland in response to darkness. It signals the body to prepare for sleep and regulates the sleep-wake cycle.
Key Functions
- •Sleep trigger — initiates the natural shutdown sequence
- •Light-sensitive — suppressed by blue light, even artificial
- •Circadian marker — release typically begins in the evening, a couple of hours before habitual sleep (dim-light melatonin onset)
- •Antioxidant — secondary roles in cellular protection
In ONDA Life
Regular morning light helps keep the body clock, and with it evening Melatonin release, on time; the popular claim of an exact "16-hour countdown" is not strongly evidenced. Blue light at night suppresses melatonin by tricking the SCN into thinking it's still noon. The Blue Light Firewall protocol protects this critical signal.
