Indoor Epidemic
Book • 2025
In Indoor Epidemic, Dr. John La Puma synthesizes medical, neuroscience, and environmental research to argue that modern indoor environments drive widespread health problems.
He explains mechanisms—like disrupted circadian signaling from lack of morning light and harmful effects of nighttime artificial light—and documents outcomes including sleep loss, cognitive drag, immune changes, and myopia.
The book offers an 'outdoor Rx' with practical, evidence-based habits such as morning sunlight exposure, midday sun for vitamin D, and intentional time in green and blue spaces to improve physiology and longevity.
La Puma emphasizes small, actionable routines (e. g.
, 10–15 minutes of morning light, horizon resets, forest bathing) that leaders and busy professionals can integrate into daily life.
He frames these adjustments as inexpensive, reversible interventions with measurable benefits for healthspan, cognition, and productivity.
