Your Nightlight Could Be Raising Your Heart Attack Risk 50%! Dr. John La Puma on The Indoor Epidemic

Sleeping with a nightlight or the TV on could raise your heart attack risk by 50%? Dr. John La Puma shares research he reviewed, which suggests that losing just 1% of your deep sleep may push your Alzheimer's risk up by 32%. If that sounds impossible, watch this episode — then send it to the caregiver, parent, or friend who needs it most. One share could change how someone sets up their bedroom tonight. In this conversation, you'll discover: Why "you're not broken — you're indoors" is reframing how doctors explain burnout, brain fog, and stubborn belly fat The "ultra-processed time" idea the New York Times picked up (and what it's doing to your body) A free morning routine that outperformed an antidepressant in one study Why sundowning in dementia may not be a mystery at all — and the simple fix most memory care facilities aren't using The 11-minute walk linked to a 23% drop in early death — plus why the surface you walk on matters more than you think A 1984 hospital study that proved a window view alone changed how fast patients healed What putting your bare hands in soil actually does to your brain chemistry The single change Dr. La Puma made in his own life after reviewing 2,200+ studies About this episode Neal K. Shah, a Johns Hopkins- and NIH-funded caregiving researcher and CEO of CareYaya, sits down with Dr. John La Puma, a physician, trained chef, and regenerative farmer who helped pioneer "food as medicine" (now taught in 80% of U.S. medical schools). Dr. La Puma's new book "Indoor Epidemic" argues that spending 93% of our lives indoors is silently wrecking our sleep, hearts, mood, metabolism, and memory — and that most of the fixes are free. They go deep on circadian rhythm and the body clock, why morning sunlight (within 60 minutes of waking, no sunglasses) sets deep sleep 14 hours later, the emerging science of chronomedicine and chronobiology, and how light, air, movement, gardening, and time outdoors act like "free medicine" with drug-level effects and no side effects. For the tens of millions of family caregivers watching, this is especially urgent: caregivers face up to a 63% higher risk of early death and depression rates as high as 70%. Dr. La Puma shares a practical "prescription" caregivers can actually follow inside the constraints they're living under — and simple ways to bring the outdoors to homebound and memory-care loved ones. Common questions this episode answers: Does sleeping with a light on affect your heart? What is the best time to get morning sunlight for better sleep? Is sunlight a "drug"? What causes sundowning in dementia? What is the best single exercise for longevity? How can caregivers protect their own health? Can gardening lower dementia risk? What is "ultra-processed time"?
