(NaturalNews) Is it true that those who suffer from Multiple sclerosis (MS) just need a little sun? Researchers at the University of Oxford seem to think so. In 2006, a study by the Journal of the American Medical Association suggested higher levels of vitamin D might decrease overall risk of developing MS. Now researchers at the University of Oxford are backing that study with further evidence while also suggesting a link between lack of sunlight and how the body responds when faced with an infection. The research concludes that MS is caused by several factors working in combination but clearly correlates to a lack of vitamin D.

Is it really as simple as soaking up some rays?

While the phenomenon of vitamin D deficiency is seen all over the world, countries in the northern hemisphere have been linked to significantly higher rates of MS. Scotland, for example, has one of the largest populations of MS sufferers, while the disease is "virtually unknown" in Africa. Even in sunny areas of the globe, it's not uncommon for people to become vitamin D deficient during the winter, as the sun's rays aren't often high enough to penetrate atmospheric layers.
