Psoriatic arthritis is a chronic autoimmune disease that affects the joints and skin, bringing significant challenges to the sick people. This final paper investigates the key role of non-pharmacological treatment in the context of improving quality of life and slowing disease progression. Although pharmacological treatments exist, non-pharmacological approaches are essential for complementary management of this disease. This paper analyses various aspects of the non-pharmacological treatment of psoriatic arthritis. Lifestyle changes, including nutrition and physical activity, play a key role in reducing symptoms and improving the overall health of patients. Physical therapy and rehabilitation are also being investigated, providing insight into their benefit in relieving symptoms and maintaining joint functionality. Emphasis should also be placed on a multidisciplinary approach in the treatment of psoriatic arthritis and how different non-pharmacological strategies can synergistically contribute to improving quality of life. The study of available literature and clinical experience provides a comprehensive overview and understanding of the non-pharmacological treatment of psoriatic arthritis and encourages further research in this important area. This paper highlights the importance of a holistic approach in PsA management and provides useful guidance for therapeutic options that do not include medication. .
