14. Fights Against Multiple Sclerosis

The regulatory effects of vitamin D on the body’s immune system has been found to help protect against multiple sclerosis, a debilitating disease where the body’s defenses attack healthy nerves, causing paralysis and movement disorders.

Studies have found that exposing young individuals aged 6-15 to sunlight, an important factor in vitamin D synthesis, reduces the chances of them developing multiple sclerosis later in life. This is evidenced by the lower incidence rates of multiple sclerosis in places with sunny climates.
