Sunlight and human health: vitamin D synthesis dose-response
Comprehensive review establishing the dose-response relationship between sunlight exposure and vitamin D synthesis, with implications for bone health, immune function, and mortality.
Vitamin D Synthesis
- 1000-2000 IU/hour of sun exposure (summer)
- Skin type affects synthesis efficiency
- Latitude affects year-round synthesis
Health Outcomes
Optimal vitamin D (>30 ng/mL) associated with 20-30% lower all-cause mortality.
Outcomes
- All-Cause Mortality Rate-25
