Sunlight, vitamin D might diminish MS risk

New research on multiple sclerosis and sunlight finds that sun exposure and vitamin D may play a role in the risk of developing the chronic illness.

It's long been recognized that MS is seen more often in people who live in colder climates. Now a report in the journal Neurology concludes people with more sun exposure are 60 percent less likely to develop the first symptoms of multiple sclerosis.

Those with the highest vitamin D levels were also less likely to have early signs of MS.

Scientists caution that the line between sunlight and skin cancer is well established and people still need to limit exposure to the sun.
