Lack of Sunlight Increases MS Risk

MELBOURNE, April 30 (UPI) — Babies whose mothers don’t get enough sunlight during the early part of pregnancy are more likely to develop multiple sclerosis, scientists in Australia said.

A lack of sunlight — the main source of Vitamin D — during the first three to four months of pregnancy can affect how a baby’s central nervous and immune system develops, said scientists from the Royal Children’s Hospital in Melbourne and Australian National University in Acton.


Babies born in November and December, during the Australian summer, had their early months in the winter and so were 32 percent more likely to develop MS than babies whose early months were in the summer and were born in May and June, during the Australian winter, the scientists said. Their results from studying 1,524 patients with MS born between 1920 and 1950 appeared recently in an online edition of the British Medical Journal.

“These results add to the weight of existing evidence suggesting vitamin D plays a role in the development of MS,” Doug Brown, an MS researcher, told The Times of London in a story published Friday.
