Dr. John La Puma is a board-certified internist and two-time New York Times bestselling author who has spent his career asking a simple question: why are modern humans so sick in environments we were never designed to live in?Early in his career, Dr. La Puma founded the field of Culinary Medicine and co-taught the first Culinary Medicine course at a U.S. medical school, helping bring food, metabolism, and lifestyle back into mainstream medical education. Culinary Medicine is now taught in roughly 80% of U.S. medical schools.His focus has since widened beyond food to the environment shaping human biology. His work examines how light, movement, time outdoors, and daily exposure to nature influence sleep, focus, metabolic health, immune function, and resilience - inputs his research shows are often more powerful than medications or devices alone. Indoor Epidemic: 93% Inside Steals Sleep, Focus & Years-The 7% Outdoor Rx Restores Them is the clinical framework built from that work.Dr. La Puma lives and works in Santa Barbara, California, where he continues to study and live the relationship between environment, lifestyle, and long-term health.

RECLAIM YOUR BIOLOGYThe 7% Outdoor Rx for Modern Humans You've optimized your diet, tracked your sleep, and tried every productivity hack-yet you still wake up exhausted, wired, and unable to focus. The problem isn't your willpower or your screen time. It's neuroendocrine dysregulation: your circadian, cortisol, and dopamine systems are miscalibrated by chronic indoor exposure. Modern life traps us indoors for 93% of our time-under artificial light, staring at screens, disconnected from the natural signals that regulate energy, hormones, attention, and recovery. The result is familiar: burnout, brain fog, poor sleep, metabolic dysfunction, and accelerated aging.Digital Obesity: The Hidden Driver of Burnout Digital saturation, artificial light, and lack of time outdoors create what Dr. John La Puma calls Digital Obesity: a neuroendocrine and circadian mismatch that disrupts cortisol rhythm, dopamine regulation, attention, and metabolic flexibility. It's what happens when human biology is trapped indoors. This physician-authored framework shows how repurposing part of the 7% of your week you already spend outdoors can help restore energy, focus, resilience, and long-term health. No supplements, biohacking gadgets, or extreme routines required.Parents: This Works for Kids Too Since 2020, childhood depression has surged while outdoor time has plummeted. Teen antidepressant prescriptions rose 69% in six years. The 7% Outdoor Rx offers a practical, medication-free way to help restore focus, mood, and resilience for the whole family. This is a biological reset for growing brains in an indoor world.Evidence-Based. Medical-Grade. Zero Wellness Hype.
