Laughter has long been regarded as an effective form of medicine. Now, research suggests that having a good laugh can alleviate symptoms of heart disease.
A trial conducted in Brazil aimed to determine if “laughter therapy” could improve cardiovascular symptoms. The study involved 26 adults with an average age of 64, all of whom had been diagnosed with coronary artery disease.
Half of the participants were shown comedy programs every week for three months, while the other half watched serious documentaries.
The group exposed to comedy experienced a 10% improvement in their heart’s ability to pump oxygen throughout the body. Additionally, their arteries’ ability to expand also improved.

Furthermore, the laughter group experienced significant reductions in inflammatory biomarkers, indicating a decrease in plaque build-up in blood vessels and a lower risk of heart attack or stroke.
Professor Marco Saffi, the lead author of the study from the Hospital de Clinicas de Porto Alegre in Brazil, stated, “This study found that laughter therapy could help reduce inflammation and decrease the risk of heart attack and stroke. Laugh therapy could be implemented in institutions and health systems, such as the NHS, for patients at risk of heart problems.”
Experts believe that laughter benefits the heart by releasing endorphins, which reduce inflammation and promote relaxation in the heart and blood vessels. It also lowers levels of stress hormones, which can strain the heart.
