So do we glow when sunlight hits the skin? Yes, we do. What kind of light do we glow with? ELF-UV light manifests in our blood plasma = do we gain or lose electrons when this occurs? We lose electrons and give them to other anions in our blood. Sulfated amino acids are added to many proteins and lipids in our blood under the power of sunlight. Sunlight increases sulfhydryl groups which are the major anions in our blood plasma.
