New study shines light on lifetime sun exposure and multiple sclerosis.
Rates of multiple sclerosis (MS) are typically higher in northern countries, where sunlight is in shorter supply. These rates have led researchers to consider increased sunlight exposure—particularly in the form of ultraviolet or UV-B rays—as a possible prevention for this autoimmune disease. But the specifics of this relationship remain poorly understood. A new research study by Vancouver Coastal Health Research Institute scientist Dr. Helen Tremlett provides more details about the sunlight-MS connection. Importantly, Tremlett’s study looks at different life stages and seasonal exposure in relationship to MS.
