Lesson Overview

5.9 – The Science of Melatonin and Light Exposure: Melatonin is your body’s natural “sleep switch.” Light, especially blue light, tells your brain to stop making it. Darkness signals your body to release more and prepare for rest. This is why screen time at night delays tiredness. Morning sunlight, however, resets your melatonin timer for the next night. Using dim, warm lights in the evening supports natural production. Supplements can help but should be used carefully and short term. The best way to boost melatonin is through rhythm and light control. Treat light like a schedule cue for your body clock. When your light habits align, sleep happens more smoothly.
