Burning Questions
Viewers seek clarity on how to balance sunlight exposure for vitamin D, circadian rhythm, and skin safety. They ask how latitude, time of day, and season affect benefits, and whether sunscreen and sunglasses block the “good” wavelengths. Many also wonder how eye and brain health tie to sunlight, what to do when levels exceed 100 ng/mL, and which supplements — D3, K2, magnesium — are essential. Interest extends to red and infrared therapy, safe indoor light, and whether window glass or CO₂ levels in buildings blunt natural benefits.
