Sunshine may protect children, young adults from multiple sclerosis
Hindustan TimesA new study has found that exposure to UV rays boost vitamin D, which may protect against auto-immune disease. When the researchers adjusted for MS risks, like smoking and female sex, they found that the participants who spent an average of 30 minutes to one hour outdoors daily had a 52 per cent lower chance of MS, compared to those who spent an average of fewer than 30 minutes outdoors daily. "Sun exposure is known to boost vitamin D levels," said co-senior author Emmanuelle Waubant, MD, PhD, professor in the UCSF Department of Neurology and of the Weill Institute for Neurosciences. Clinical trials are needed to determine if "increasing sun exposure or vitamin D supplementation can prevent the development of MS or alter disease course post-diagnosis," she said. Meanwhile, "advising regular time in the sun of at least 30 minutes daily especially during summer, using sun protection as needed, especially for first degree relatives of MS patients, maybe a worthwhile intervention to reduce the incidence of MS." Limited sun exposure and/or low levels of vitamin D have been associated with other conditions.
