Indoor Epidemic: Prescribing Nature, Light, Air, and Movement with Dr. John La Puma, internist, chef, and regenerative farmer. His book, "
Indoor Epidemic," argues that spending about 93% of life indoors undermines health through poor light timing, air quality, limited movement, and reduced nature exposure. La Puma cites data that outdoor morning light helps set circadian rhythms, while nighttime blue light can impair sleep quality and raise cardiovascular risks, referencing a large UK Biobank study. He discusses indoor pollutants and CO2 buildup affecting inflammation and cognition, recommends strategies like getting daylight early (even just a sky view), using circadian lighting, and taking brief outdoor breaks to reduce myopia risk. He describes measurable benefits of forest bathing and gardening (including immune and mood effects), notes hospital studies linking window views to shorter stays and less pain medication, and reviews his pioneering work in culinary medicine now taught widely in medical schools, emphasizing cooking and growing food as preventive and therapeutic tools.
