CANCER, CHRONIC DISEASES
Chemotherapy is associated with a wide range of physical and psychological side effects, so complementary and alternative therapies may be practiced as an independent treatment or combined with the standard ones to improve health-related quality of life of cancer patients. Laughter yoga has predominantly been used as a complementary therapy to enhance health and wellbeing of ordinary people and patients with chronic diseases. However, to date, few studies have evaluated the effects of this modern exercise on cancer patients undergoing chemotherapy in clinical settings, to the best of the authors’ knowledge. the present study aimed to investigate the effects of Laughter Yoga on the health-related quality of life of cancer patients undergoing chemotherapy.
