Psoriasis is a skin disease of immunological origin that causes a great deal of misery. It presents as swelling, itchiness, redness and flaky skin and it is difficult to cure. A recent study has demonstrated that psoriasis incidence is lower among people who exercise vigorously.
The research was conducted, only on women, in the USA. The fact that the study included no fewer than 86,665 volunteers indicates its thoroughness. For years doctors monitored the subjects’ lifestyles and kept tabs on their health. A total of 1,026 women in the study developed psoriasis. The conclusion was that people who exercise vigorously have almost a 30% lower risk of being affected by psoriasis. We now need equivalent studies in men to verify these data. Note that the authors define vigorous exercise as running at least two hours or swimming at least three hours a week at competition standard. In other words, leisurely walks in the countryside do not count.
