The Sun Isn’t the Enemy: How Light Controls Dopamine, Hormones, and Health

In this episode, we talk to David Herrera to explore why biology, not motivation, determines follow-through, discipline, and health. We dive deep into how light exposure, dopamine, circadian rhythm, cold, and modern environments shape everything from energy levels and sleep to hormones, mood, addiction, and long-term disease risk. From blue light and melatonin to vitamin D myths, sunscreen, seed oils, and why kids spend less time outside than prisoners, this conversation challenges nearly everything we’ve been taught about “health.” This isn’t about hacks. It’s about restoring the inputs humans evolved with.
