A research has raised hope for those battling with psoriasis. The researchers have said that taking part in vigorous exercise may cut the risk of psoriasis by up to 30 percent. Here it is worth noting that psoriasis is a problem of immune system in which systemic inflammation and scaling of the skin takes place.
Physical activity has been linked with a decreased risk of disorders characterized by systemic inflammation, including type 2 diabetes, colon cancer, coronary artery disease and breast cancer, reveals the study.
"Our results suggest that participation in at least 20.9 MET (metabolic equivalent task)-hours per week of vigorous exercise, the equivalent of 105 minutes of running or 180 minutes of swimming or playing tennis, is associated with a 25 percent to 30 percent reduced risk of psoriasis compared with not participating in any vigorous exercise," the authors has been quoted as saying.
Hillary C. Frankel, A.B., of Brigham and Women's Hospital, Boston, and colleagues worked on the data collected from the Nurses' Health Study II. Their study took into account 86,665 women who did not have psoriasis at baseline in 1991 and the women completed physical activity questionnaires in 1991, 1997 and 2001.
Researchers analyzed 1,026 incident cases of psoriasis as they studied the link between physical activity and the disorder.
The study reached at the conclusion that the women who were physically active had a reduced multivariate relative risk of psoriasis (0.72) in contrast to the women who were least active.
The team of researchers also observed that Walking was not linked to decreased risk of psoriasis.
"Among the individual vigorous activities we evaluated, only running and performing aerobic exercise or calisthenics were associated with a reduced risk of psoriasis. Other vigorous activities, including jogging, playing tennis, swimming and bicycling were not associated with psoriasis risk," the author has been quoted as saying.
"The highly variable intensity at which these activities are performed may account for this finding."
The authors have said that further research is needed to establish how physical activity may reduce psoriasis risk deserved further study.
"In addition to providing other health benefits, participation in vigorous exercise may represent a new preventive measure for women at high risk of developing psoriasis. Additional corroborative studies and further investigations into the mechanisms by which physical activity protects against new-onset psoriasis are needed," the researchers have opined.
