Sunnier climate reduces multiple sclerosis risk in later life when children grow as youngsters, according to the new research conducted by a team of scientists from Canada, disclosed in the journal Neurology, suggesting that the crucial factors to produce vitamin D in the body are the ultraviolet B (UV-B) rays of the sun. The team also reported that the body containing a lower amount of vitamin D is more likely to develop the risk of multiple sclerosis.

Prof. Helen Tremlett, from the University of British Columbia, Vancouver said in a statement that, “Our research showed that those who did develop MS also had reduced sun or outdoor exposure later in life, in both summer and winter, which may have health consequences. You need safe sun exposure, but at the same time don’t be afraid to go outside.”


UV-B rays help prevent the risk of multiple sclerosis, which is chronic disease that lets the immune system of the person to target the nerve cells in the spinal cord and brain, driving to cause damage. The team has also estimated that the highest ubiquity of multiple sclerosis in the world may be found in Canada.

Researchers from the University of British Columbia in Vancouver, Canada have performed the study, which has shown that the children at the age from 5 to 15 years old exposed to the sun, are in quite reduced risk of multiple sclerosis nearly by 55 per cent.

Neurologist, Dr. Asaff Harel from the Lenox Hill Hospital in New York City stated that, “While geographic location during adolescence was previously known to be associated with MS risk, the current study demonstrates that sun exposure even later in life affects MS risk.”
