UVB Sunlight Exposure to Skin and Eyes

Get regular UVB exposure from sunlight to the skin, eyes, and face throughout the year, as safely possible, to support endocrine, mood, energy, immune, pain-relief, wound-healing, and tissue-renewal pathways. Most people should likely get more UVB exposure overall, especially in winter, while avoiding sunburn and eye damage.

So for those of you that are thinking tools and protocols, try to get some UVB exposure, ideally from sunlight. I think the 20 to 30 minute protocol two or three times per week is an excellent one.
