New research suggests that laughter therapy might offer benefits similar to traditional breathing exercises for individuals living with chronic obstructive pulmonary disease (COPD), a long-term lung condition that makes breathing difficult. In the UK, around 1.7 million people have COPD, but approximately 600,000 are not yet diagnosed. This condition often results from long-term exposure to irritants like cigarette smoke, leading to symptoms such as breathlessness and coughing. A clinical trial involving 63 COPD patients at Ankara Bilkent City Hospital in Turkey explored the effects of laughter therapy compared to standard breathing techniques. Participants were split into three groups: one engaged in laughter therapy, another practiced pursed-lip breathing—a common method used to help control breathing—while the third received no specific exercises. Each group participated in 30-minute sessions three times a week for eight weeks. Researchers measured changes in their respiratory function before, during, and after the program. The results showed that both laughter therapy and pursed-lip breathing led to improvements in breathing and overall wellbeing compared to the group that received no intervention. These positive effects were still noticeable a month after the program ended. Dr. Goncagul Aldan, a nurse and lecturer at Hacettepe University, explained that the study highlights the potential of simple, low-cost techniques that can be done at home to reduce breathlessness and improve daily life for COPD patients. Laughter therapy may help by exercising the breathing muscles, encouraging deeper exhalation, and releasing endorphins, which can provide both physical and emotional relief. While the findings are promising, the exact mechanisms by which laughter therapy benefits COPD patients are not yet fully understood. More research is needed to confirm these results, particularly with larger groups of patients. The study will be presented at the European Respiratory Society (ERS) Congress in Barcelona. Emma Rubach, from Asthma + Lung UK, noted that the research adds to the growing evidence that alternative therapies, like laughter, can play a role in managing lung conditions. Although more studies are required, laughter therapy appears to be a fun and accessible method for people with COPD to help manage their symptoms.
