low sunlight exposure in connection with MS low sunlight combined with glandular fever could increase the risk of developing multiple sclerosis (MS), the researchers say.There are many suspected risk factors for MS and the disease is known to be more often away from the equator.
The study in neurology, suggested that low levels of sunlight could affect how the body responds to infection.
The study said of the MS Society, based on data of hospital admissions in England, evidence existing weight added.
MS affects about 100,000 people in the United Kingdom and is more common in the North of England.
Damage the protective layer around nerves, known as the myelin sheath. Messages from the brain with the rest of the body are disrupted, which move to difficulties, muscle weakness and blurred look.
Light plus virusThe researchers at the University of Oxford saw all hospital admissions in England between 1998 and 2005.
They found 56,681 MS cases and 14,621 cases of glandular fever, caused by the Epstein - Barr virus.The study also used data from NASA on sunlight intensity.
The researchers found they only analysis of sunlight, 61% of the variation in the number of MS cases of England could explain.
However if she combined the effect of sunlight and glandular fever, 72% of the variation in MS cases explained.
Professor George Ebers, of the University of Oxford, said: "it is possible that vitamin D [which made is when the skin is exposed to sunlight] deficiency can lead to an abnormal response to the Epstein - Barr virus."
"More research on whether UVB increases risk, or should be done with vitamin D supplements and Barr virus could reduce cases of MS possible treatments or vaccines for the Epstein."
Dr. Doug Brown, head of biomedical research at the MS Society, said: "this work deals to weight caused existing evidence by a number of factors working in combination."
"Vitamin D has been studied closely in recent years and is probably an important factor in the development of MS, we are happy to see us, dedicated to more research in this important area."
PAM MacFarlane, Chief Executive of sclerosis trust, said: "more research is necessary, but just able to predict the risk of getting to determine MS and preventive measures would be a further step forward."
