An American study has revealed that women who exercise for exercise for at least two hours a week are partially protected against psoriasis.

While it's long been known that people who are overweight are at higher risk of chronic skin disease this is the first study to establish that exercise is directly linked to likelihood of psoriasis regardless of other lifestyle habits.

Dr. Abrar Qureshi from Brigham and Women's Hospital in Boston and his colleagues looked at the exercise habits of 87,000 women over 14 years and found that women who reported the most vigorous physical activity each week were 27 percent less likely to get psoriasis than the least-active women.

"People who are looking for another reason to exercise, here's a good one," he said. "It's certainly plausible that in women who exercise more vigorously, there might be a lowering of inflammation [a key feature of psoriasis] in the body in general."

Though he did warn that: "One of the potential concerns is, the women who are exercising vigorously, are they just healthy in general, and do they have other healthy lifestyle factors that are contributing to a lower risk of psoriasis?"

In his report in the Archives of Dermatology, he added that findings only apply to women in the U.S., and further research is needed to see if there's any link between physical activity and psoriasis risk in men.

However, based on the results two hours of weekly running or four hours other aerobic exercise was tied to a 25 to 30 percent lower chance of getting psoriasis.
