Mitochondria Tune Up? With Kristina Kristen

In this episode, Adiel sits down with wellness consultant and author Kristina Kristen for a wide-ranging conversation on mitochondria — the "bioengines" she argues most of us understand far too little about. Together they explore how to use sunlight wisely by building up a "solar callus" rather than burning, why morning and late-afternoon red and infrared light matter, and how vitamin D and nitric oxide both depend on the very UV rays we've been taught to fear. They get into the modern challenge of blue light at night and its toll on sleep, the hidden health cost of energy-saving LED lighting, and the hormetic stressors — fasting, cold plunges, heat, and exercise — that push mitochondria to grow stronger and multiply. Along the way: chronic stress and cortisol, why "metabolism" and "mitochondria" are really the same story, brown fat, and a fresh take on what the Blue Zones studies might be leaving out. Kristina also shares the story behind her two books: 10,000 Suns, a 28-day mitochondria reset built around her NEST framework (nutrition, exercise, sleep, toxin avoidance, and stress control), and Beyond Just Genes: Welcome to the Energetic Revolution.
