Self-administered laughter therapy improves breathing in some COPD patients

A recent pilot study examined whether an eight‑week program of self‑administered laughter therapy could improve respiratory function in individuals with chronic obstructive pulmonary disease (COPD). Participants were instructed to engage in daily laughter exercises—such as watching comedic videos and practicing forced giggling—without direct supervision. Over the course of the intervention, a modest subset of the cohort demonstrated measurable improvements in lung capacity and reported reduced shortness of breath, as assessed by standard spirometric tests and patient‑reported outcome questionnaires.

The findings suggest that laughter‑based interventions may offer a low‑cost, non‑pharmacologic adjunct for managing COPD symptoms, although the small sample size and lack of a control group limit the generalizability of the results. Researchers recommend larger, randomized trials to confirm efficacy and to explore the mechanisms by which laughter influences airway dynamics. If validated, self‑administered laughter therapy could become a complementary option for patients seeking to enhance their breathing comfort alongside conventional treatments.
