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 ~16 hours after morning light exposure
- •Antioxidant — secondary roles in cellular protection
In ONDA Life
Morning light exposure sets a 16-hour countdown for Melatonin release. 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.
