You do everything right. You are still exhausted.

You track your sleep. You try to eat well. You take vitamins. You follow protocols. You still wake tired, crash at 2 pm, lie awake wired at 3 am, and cannot focus.

The problem is not your willpower. It is where you spend your time.

We spend 93% of our lives indoors, under artificial light, staring at screens. Digital saturation turns your hours into what Dr. John La Puma calls "ultraprocessed time": stripped of the natural signals that regulate sleep, hormones, attention, and metabolism. The result is inflammation, burnout, brain fog, impaired immunity, and metabolic dysfunction. Your risk for heart disease and diabetes rise. Burnout is not psychological. It is not willpower. It is indoor confinement.

The prescription is simple. Intentional time outdoors at the right time acts like medicine. Repurpose just 17 minutes daily that you already spend outside: the minimum effective dose to move blood pressure, mood, memory.

You will sleep deeply using light and temperature instead of medication. Restore metabolic flexibility with daylight and meal timing. Clear brain fog by fixing its cause. Fill the 7% Outdoor Rx using dozens of microdose prescriptions that fit any schedule.

For parents and educators: since 2020, childhood depression has surged while outdoor time has fallen. Screens and the bed rotting that follows them, are not a discipline problem. It's environmental. This is a medication-free way to restore focus, mood, and sleep for the whole family.

John La Puma, MD, is a board-certified internist and two-time New York Times bestselling author. He reviewed 2,200 peer-reviewed studies to find the right dose of nature for your condition. In 2025 he led the first skills-based Nature as Medicine CME course for physicians in the US, at UCLA.
