Your daily rhythms are set less by habit and choice than by the natural light-dark cycle, which resets an internal clock deep in the brain. Morning sunlight and dim evenings keep sleep, mood, and metabolism in sync, while artificial light at night throws them off. Align your day with these light cues and you can sleep better and lower your risk of metabolic trouble.

The evolutionary mismatch hypothesis argues that many modern chronic diseases like obesity and type 2 diabetes stem from a conflict between our bodies, adapted for Paleolithic diets, and today's industrialized, agricultural foods. Unlike mainstream views that focus on individual choices, this perspective highlights how rapid dietary changes outpaced human genetic adaptation, suggesting that aligning our diets closer to ancestral patterns could improve health outcomes.
