Episode notes
Indoor Lighting
- Use incandescent lighting indoors (2700 Kelvin or lower).
- Avoid higher color temperatures indoors as they trigger hormones suited for outdoor activity.
Melanin Types
- There are two types of melanin: eumelanin (brownish-black) and pheomelanin (reddish).
- Pheomelanin acts as a photosensitizer, producing excessive reactive oxygen species, while eumelanin absorbs and dissipates UV radiation.
Sunlight Exposure
- Expose yourself to midday sun when your shadow is shorter than your height to produce vitamin D.
- Increase sun exposure gradually, checking for redness a few hours later to determine your tolerance.
