Psoriasis and Exercise: A Review

Psoriasis is a prevalent inflammatory skin disorder that is associated with a number of comorbidities including cardiovascular disease and metabolic syndrome. Exercise can influence the outcomes of chronic inflammatory diseases, and the presence of these diseases can also influence physical activity in afflicted patients. We reviewed the available literature published on exercise in psoriasis patients and aimed to explore physical activity levels, barriers to exercise, physical fitness, exercise as a prevention strategy as well as a treatment modality. Overall, patients with moderate to severe psoriasis are more sedentary than the general population and experience barriers to exercise secondary to their skin disease. Moderate to vigorous exercise may be an independent preventative factor in reducing the incident risk of developing psoriasis and the utilization of exercise as a weight loss strategy may improve disease severity especially in overweight patients. Expert panels agree that exercise can be beneficial as an adjunct treatment in patients with psoriasis who are overweight; however, more randomized clinical trials are needed to establish these links.
