Summary
This episode is brought to you by Puori, Hollow Socks, Fatty15, and Branch Basics. Light shapes far more than our sleep; it influences our metabolism, hormones, energy, and long-term health. Yet modern life has quietly flipped our light environment upside down: too little sunlight during the day and too much artificial light at night. Today’s episode explores why that mismatch may be costing us far more than we realize. Today on The Dhru Purohit Show, Dhru sits down with Jonathan Jarecki to explore the critical role of sunlight, especially infrared light, in health and longevity. They break down key studies on sun exposure, including its impact on melatonin production, metabolic health, and overall well-being. Jonathan also shares his 2026 Light Challenge (with beginner and advanced levels) and practical strategies for getting more natural light during the day, reducing artificial light at night, and understanding the health risks of inadequate sun exposure. This episode is a powerful reminder that light isn’t just a backdrop to our lives, it’s a biological signal that shapes long-term health. Jonathan Jarecki is a pre-medical student, studying Biology and Neuroscience. He’s passionate about preventive medicine, evidence-based wellness, and translating cutting-edge research into practical tools for everyday life, exploring how light, water, and bioelectromagnetism shape health, performance, and longevity.
