The Synthesis
Dr. John La Puma ā physician, chef, regenerative farmer, and two-time New York Times bestselling author ā is pioneering a new medical frontier: identifying indoor living itself as the root cause of disease. He calls it the Indoor Epidemic: the reality that we spend 93% of our lives inside, under artificial light and recycled air. The cost is staggering ā disrupted sleep, chronic stress, accelerated aging, and diminished resilience. His solution is Outdoor Rx: a science-based prescription framework that restores health by rebuilding the missing foundation layer of longevity ā structured time outdoors. From morning light resets that restore circadian rhythm to awe walks that lower inflammation, Dr. La Puma shows how just 7% of your time outdoors can amplify every other health intervention, extend healthspan, and reverse burnout.
