Aliquot #121: Harnessing Natural Light for Better Sleep
Imagine a drug that improves sleep, reduces stress, sharpens focus, and boosts mood—without cost or side effects. That "drug" is light. Natural light is more than just illumination; it's a potent regulator of our body's internal clock, driving critical processes like hormone release and sleep-wake cycles. But in a world dominated by screens and artificial lighting, many of us unknowingly deprive ourselves of its benefits, with far-reaching consequences for our health.
