Unlearn Health explores how modern environments quietly disrupt human biologyâand how restoring natural signals improves energy, mood, resilience, and long-term health.
This site focuses on signals, not symptoms: light, timing, temperature, movement, water, and environment.

Start With the Foundations
Most health advice focuses on inputs like calories, supplements, or workouts.
Unlearn Health focuses on environmental signals that control how biology actually functionsâespecially circadian rhythm, mitochondrial energy, and cellular repair.
Health improves fastest when interference is removed.
âĄď¸Â Intro
- You Are Not Broken
- Health Is Input, Not Effort
- The Four Environmental Signals That Control Your Biology
- Why Modern Life Breaks Health
These help support the initial shift in your perspective toward living an optimal life.
đ Sunlight
Electromagnetism is the foundation of health. Sunlight is the primary source of it in nature.
These explain why sunlight and natural electromagnetism make up the foundation of health.
đĄArtificial Light
Artificial light is one of the strongest modern disruptors of human health.
Start with:
- Blue Light and Skin Cancer
- Flicker and Blue Light Toxicity
- Melanopsin, Light, and the Biology of Sleep
These explain why sleep, mood, hormones, and aging are light-regulated processes.
⥠Energy, Mitochondria, and Aging
Energy productionânot caloriesâdetermines health and lifespan.
Start with:
These articles explain why environment, timing, and repair capacity matter more than intensity.
đą Food, Seasonal Eating, and Electrons
Energy productionânot caloriesâdetermines health and lifespan.
Start with:
These articles explain why food is a key signal of your environment for your health, not just fuel.
đ§ Seasons, Cold, and Environmental Stress
Biology needs change. Constant comfort counterintuitively increases cellular stress.
Start with:
These show how cold, fat, and seasonal signals train mitochondrial strength if you are living in a winter environment.
đĄ Technology and Modern Stressors
Modern stressors donât break biology overnightâthey accumulate.
Start with:
This section connects technology, stress, and long-term aging.
Why âUnlearnâ
Most health problems persist because we keep adding interventions instead of removing mismatches.
Unlearning means:
- Removing harmful signals first
- Restoring natural inputs
- Letting biology self-correct
Health is not something you force.
Itâs something you stop interfering with.
