In the world of chronic obstructive pulmonary disease (COPD) management, treatments tend to fall into familiar categories: inhalers, pulmonary rehabilitation, breathing exercises, and medications. But a new clinical trial presented at the European Respiratory Society (ERS) Congress in Barcelona suggests an unconventional addition to the therapeutic arsenal – laughter therapy.<\/p>\n
Researchers at Ankara Bilkent City Hospital in T\u00fcrkiye conducted a randomized trial involving 63 people with COPD. Participants were divided into three groups: one-third received laughter therapy, one-third practiced traditional pursed-lip breathing exercises, and one-third served as a control group with no breathing exercises.<\/p>\n
Both intervention groups were taught their assigned techniques face-to-face, then asked to practice for 30 minutes, three times per week for eight weeks. Researchers supported them with video calls and text messages to encourage adherence.<\/p>\n
The results, presented by Dr. Goncagul Aldan, a lecturer and nurse from Hacettepe University Faculty of Nursing, showed that both laughter therapy and pursed-lip breathing significantly reduced breathing difficulties compared to the control group\u2014and the effect persisted even one month after the program ended.<\/p>\n
Laughter therapy is a structured intervention designed to evoke the physiological effects of genuine laughter in the body. In this trial, patients learned a series of specific exercises:<\/p>\n
Rhythmic clapping with vocal sounds<\/p>\n
Playful laughter exercises, such as mimicking a motorcycle starting or a lion’s roar<\/p>\n
Laughter meditation with spontaneous, unforced laughter<\/p>\n
Relaxation with calm breathing and smiling<\/p>\n
The approach is based on the principle that the body cannot distinguish between simulated and genuine laughter\u2014both produce similar physiological responses.<\/p>\n
The mechanism isn’t fully understood, but Dr. Aldan offered several hypotheses. In COPD, airways tend to collapse during exhalation, trapping stale air inside the lungs. Pursed-lip breathing\u2014the established comparator in this trial\u2014creates gentle back pressure that allows trapped air to escape, slows the breathing rate, and helps patients feel more in control.<\/p>\n
Laughter therapy may work through different but complementary pathways:<\/p>\n
Exercising the breathing muscles through the physical act of laughing<\/p>\n
Promoting deeper exhalation, potentially helping clear trapped air<\/p>\n
Triggering endorphin release, offering both physical and emotional relief<\/p>\n
Reducing stress and anxiety, which can worsen breathlessness perception<\/p>\n
After the eight-week intervention period:<\/p>\n
Breathlessness: Both laughter therapy and pursed-lip breathing groups had significantly less difficulty breathing compared to the control group<\/p>\n
Overall health: Both treatment groups showed better overall health scores<\/p>\n
Care needs: No difference between groups in how much day-to-day care patients required<\/p>\n
The sustained effect\u2014one month post-program\u2014is particularly noteworthy, suggesting patients continued practicing or retained benefits beyond the formal intervention period.<\/p>\n
“Managing COPD requires more than medication alone,” Dr. Aldan said. “Patients need a holistic approach to help them cope with their symptoms, the physical burden of the disease, and its emotional and psychological impact.”<\/em><\/span><\/p>\n The study was also positively assessed by Dr.<\/span> Marc Miravitlles, Vice President of the European Respiratory Society.<\/span> According to his assessment, despite its small scale, this is a well-organized study with promising results.<\/span> The expert emphasized that laughter therapy is a simple, inexpensive, and universally accessible method that helps patients with COPD improve their breathing and alleviate their overall condition.<\/span><\/p>\n The researchers are careful not to overstate the findings:<\/p>\n Small sample size: 63 patients is relatively modest for a clinical trial<\/p>\n Mechanism unclear: How exactly laughter therapy reduces breathlessness needs further investigation<\/p>\n Not a replacement: This is positioned as complementary to existing care, not a substitute for standard treatment<\/p>\n More research needed: The team hopes to study laughter therapy on a larger scale with more patients and collaborate internationally across different clinical settings<\/p>\n The researchers plan to expand their work with larger-scale studies and international collaborations. Understanding the mechanisms\u2014whether through respiratory muscle training, improved exhalation dynamics, endorphin-mediated symptom modulation, or stress reduction\u2014will be crucial for optimizing the intervention.<\/p>\n Sometimes, the old adage that “laughter is the best medicine” might have more truth to it than we realized\u2014at least when it comes to breathing easier with COPD.<\/p>\nImportant Caveats<\/strong><\/h5>\n
