The fascinating intersections of circadian biology, quantum health, and women's wellness really come alive as I sit down with Neurosurgeon-turned-Quantum-Biologist Dr. Jack Kruse. You'll hear how simple things, like the light you see first thing in the morning, quietly shape your hormones, energy, and even how you age. Dr. Jack's decades of surgical and biophysical knowledge make these concepts surprisingly practical for everyday health. By the end, you may find yourself rethinking your daily routines in the best way.

Together, we get into why AM sunlight can make such a big difference for women going through hormonal changes, especially around menopause. Dr. Jack breaks down big ideas like heteroplasmy in simple, eye-opening terms and shows how it plays into skin health, longevity, and mitochondrial function. You'll also hear why red light deserves a place in your wellness routine, and how blue light and non-native EMFs might be draining more than just your battery.

If you've ever struggled with weight changes, low energy, or hormonal shifts, you'll appreciate Dr. Jack's explanation of the leptin-melanocortin pathway and what it means for women at every age. His own 150-pound weight-loss story adds real heart to the science and shows how much can change when your environment starts working for you instead of against you. This episode delivers a mix of empowering insights and simple shifts you can start today for better vitality.
