New research shows that low levels of sunlight, coupled with glandular fever, could increase your risk of developing multiple sclerosis (MS). This could be one reason that MS tends to be more common away from the equator.
The study suggested that low levels of sunlight could affect how your body responds to infection. Vitamin D deficiency could be another possible link.
BBC News reports:
"The researchers found that by just analyzing sunlight, they could explain 61 percent of the variation in the number of MS cases across England. However when they combined the effect of sunlight and glandular fever, 72 percent of the variation in MS cases could be explained."
Remember, when the American Cancer Society, or dermatologists, tell you that you should be avoiding the sun at all costs, they are dead wrong.
