Lack of Sun Exposure Linked to MS Risk

People who have spent more time in the sun, along with those who have higher vitamin D levels, may be less likely to develop multiple sclerosis.

Previous studies have shown that people living close to the equator are less likely to get multiple sclerosis. Now, a new study looked at over 200 adults who had just started having the first symptoms of MS, along with a comparison group with no signs or symptoms of MS.

Reuters reports:

"On average, people with the first signs of MS had been exposed to a smaller 'UV dose' -- based on how much time they had spent in the sun and how close to the equator they had lived -- over the course of their lives. People with early MS ... [also had] vitamin D levels 5 to 10 percent lower than those without MS."
