Women who exercise vigorously may be reducing their risk of psoriasis. That's according to a new study done at Harvard University. Psoriasis is an immune disorder that causes inflammation and scaly patches on the skin.
Vigorous activity for up to three hours a week can potentially reduce the risk by 25 percent to 30 percent. However, only activities such as running, aerobic exercise or calisthenics were linked to a reduced risk of the condition. Other activities such as jogging, playing tennis, swimming and bicycling were not associated with psoriasis risk.
Researchers say in addition to reducing inflammation, exercise might also reduce stress and depression, which are also associated with psoriasis.
