‘Ever since scientists convicted sunlight of causing skin cancer, many seemingly sensible people have been running around slathered in sunscreen, using hats and long sleeves to hide our skin from the sun as if we were vampires. Now it looks like we may have gone too far: We may be missing out on the benefits of sunshine.
A study (press release) released today in the journal Neurology indicates that children who spend more time in the sun may have a decreased risk of multiple sclerosis. In pairs of twins where one twin had multiple sclerosis, the MS-free sibling had spent more time outside, playing team sports and sun tanning. Scientists theorize that ultraviolet rays in sunlight trigger a protective response that protects the body from this chronic nervous system disorder, either by altering the immune system or by producing vitamin D. Twins that spent more time in the sun decreased their risk of getting MS by almost 50%, despite their genetic predisposition toward the disease.’
