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,
