Full transcript
Five to ten minutes of outdoor light, inside thirty minutes of waking. That window sets your circadian clock, boosts the cortisol awakening response and improves night sleep. I step outside before the coffee, not after — after is when it gets skipped. No equipment, no app, and the evidence behind it is high. Cheap and repeatable beats perfect. agegen.ai.
