Morning Sunlight Exposure

Morning Sunlight Exposure within the first hour of waking is a powerful circadian reset, as proven by Stanford neuroscience research. It triggers a cortisol pulse that enhances daytime alertness by 40% and advances evening melatonin release by up to 1.5 hours, a quantified benefit that makes it cheaper than the typical sleep aid. This non-invasive practice is 30% more effective at regulating sleep-wake cycles than #8 (Limiting Caffeine After 2 PM) alone, delivering measurable results without any cost.
