Arthritis risk is linked to lesser sunshine exposure!


Sunlight is linked to lesser risk for rheumatoid arthritis says a latest study. Is this not contradicting to the view that the UV radiation is hazardous to skin?

The finding indicates that the older women who have had greater exposure to sunlight may have a lesser risk to rheumatoid arthritis; the reason being the Ultraviolet B or the UV- B present in sunlight. The younger women, however, would mos t probably limit their sun exposure by sun screen and other protective things due to the fear of skin problems including cancer.

What was the study? Nearly 235,000 women participated in this two-phase U.S. Nurses’ Health Study. In the first phase, nurses aged 30 to 55 years were studied from 1976 through 2008. In the second phase nurses aged 25 to 42 were studied from 1989 through 2009.

The current online edition of the journal “Annals of the Rheumatic Diseases” says that about 1314 women developed rheumatoid arthritis at the end of the two phases and concluded that in the first phase of the study, those with the highest exposure to UV-B were 21% less likely to develop rheumatoid arthritis compared to the lowest exposed ones.

The exposure of UV-B was calculated based on their respective place of living as well as the exposure at birth and by their age 15. However, no association could be made between sun exposure and rheumatoid arthritis in the second phase consisting of younger women because they avoided excess sun exposure. So, findings did not prove any cause-and effect relationship.

"Our study adds to the growing evidence that exposure to UV-B light is associated with decreased risk of rheumatoid arthritis," concluded Dr. Elizabeth Arkema of the department of epidemiology at Harvard School of Public Health.

So, we don’t know how UV-B exposure can reduce the risk of rheumatoid arthritis, but it could be by all means due to the skin’s ability to produce vitamin D in response to sunlight,
