Laughter exercises show promise for COPD patients
In a small randomized trial, eight weeks of laughter therapy improved breathing in people with chronic obstructive pulmonary disease. The therapy involved playful exercises like mimicking a motorcycle start and lion roars, alongside relaxation techniques. The results suggest a low-cost complementary treatment for COPD.
The randomized trial enrolled 63 participants, all continuing standard medications, and split them into three groups. One group practiced pursed-lip breathing, another followed a structured laughter routine involving simulated motorcycle starts and lion roars, and the third served as a control. Sessions lasted 30 minutes, three times weekly over eight weeks.
Beyond improved breathing and overall health, benefits persisted for at least a month after the trial ended. However, the interventions did not reduce daily caregiver dependence. Findings were presented at the European Respiratory Society Congress, with researchers suggesting the therapy may work by exercising respiratory muscles and lowering stress hormones.
This study could offer a low-cost, accessible adjunct to standard COPD care, potentially improving daily breathing and emotional well-being for millions affected by the condition. If larger trials confirm these findings, laughter therapy may become a practical, non-pharmacological option that reduces reliance on intensive medical interventions. However, the small sample size and lack of direct comparison to standard breathing exercises mean its true clinical value remains uncertain, though it could meaningfully enhance patient quality of life.
