Sunlight and Low BMI May Help Avoid MS


Danish investigators found a strong protective effect of adolescent summer sun exposure and body mass index (BMI) at age 20 on later onset of multiple sclerosis (MS). Not spending time in the sun every day during the teen years was associated with earlier onset of MS; and similarly, a higher BMI at age 20 was associated with earlier MS. More research is needed.

PositiveTip: Young people should enjoy daily activities outdoors in the sunlight.
