                                        Sunlight is a known anti-inflammatory agent as well as an immune, and DNA booster.
The mechanism could hinge with how UV light changes the gut microbiome.
Our deeper understanding of microbial populations living throughout the human microbiome shows how sunlight travels directly to your DNA.
Research shows how decreased exposure to sunlight and the resultant impairment in the production of vitamin D, as well as dysbiotic changes in the makeup of the gut microbiome. However, it was unclear for a long time if there are any direct links between sunlight/UVB light and the gut microbiome.
Now, a study from researchers at the University of British Columbia shows how exposure to sunlight can change the human gut microbiome, specifically in people who are vitamin D-deficient.
Human participants could help to explain the protective effect of UVB against inflammatory diseases such as multiple sclerosis or inflammatory bowel disease.
High rates of vitamin D deficiency in people who live in locations with long winter seasons, where the lack of UVB from sunlight means they don’t produce enough of the vitamin. Limited UVB exposure is one of the most important environmental factors linked to the onset of immune-mediated chronic inflammatory diseases such as multiple sclerosis and inflammatory bowel diseases. 
Vitamin D is also known to promote intestinal health, with vitamin D deficiency shown to promote dysbiosis of the gut microbiota, even in healthy individuals. However, it’s still unclear if there is a direct association between UVB light and human intestinal microbiota.
Additionally, the VDR receptor turns on thousands of genes throughout the human body. When we begin to understand the full impact of sunlight on the body, there is no part of biology not affected by UV light from the life force of our nearest star.
When possible, it’s very important to get sunlight exposure. For vitamin D production this includes midday sun where UVB light rays are at their highest, and the skin produces vitamin D.
Full daytime spectrum has added benefits, including controlling circadian rhythm.
Have you had your vitamin D levels tested recently?
