Sunlight, not Vitamin D, Profoundly Reduces the Risk of Eczema and Hay Fever in Adolescents.

Sunlight, not Vitamin D, Profoundly Reduces the Risk of Eczema and Hay Fever in Adolescents.

The positive effects of sunlight continue to mount; a study of 415 subjects showed that 16-year olds, who spent more than 4 hours per day in the sunlight during summer, had a significantly reduced risk of eczema and hay fever.[1] The researchers could not pinpoint the reason for the protective effect of sunlight, but surmised that it could be due to a change in the immune system.

There was no correlation of vitamin D levels to the risk of these two disorders, meaning that sunlight exposure worked independently of vitamin D. This is another in a growing list of sunlight benefits demonstrating that sunlight has splendid healing powers beyond its ability to stimulate vitamin D production in the skin. I expect many more such findings in the coming years.

The message is this: get plenty of regular, safe sunlight exposure, and don’t rely on vitamin D supplements to furnish all of Sun’s healing powers; it can’t. Remember also that if vitamin D is needed to improve health, sunlight is the most natural source.
