Laughter Linked to Better Heart Health, Studies Show

Laughter can help protect the heart by stimulating blood vessel health and reducing stress hormones, according to cardiologists. Recent research highlights that joy and laughter may play a key role in preventing cardiovascular disease, countering the well-known risks of chronic stress.

How Laughter Affects the Heart

• Laughter triggers the release of endorphins, which stimulate the inner lining of blood vessels (endothelium), leading to the production of nitric oxide that relaxes arteries Source: Listín Diario.
• It also reduces stress hormones like cortisol and epinephrine, which can constrict blood vessels and raise blood pressure Source: Diario Libre.
• Dr. Brett Carroll, director of Vascular Medicine at Beth Israel Deaconess Medical Center, states: "Laughter can have a beneficial effect that promotes the health of blood vessels" Source: Listín Diario.

Preventable Risk Factors

While some risk factors (age, gender, genetics) are non-modifiable, a large proportion of heart attack risk is linked to lifestyle. According to Columbia University Irving Medical Center, 90% of heart attack risk in men and 94% in women can be attributed to controllable factors such as high blood pressure, high cholesterol, diabetes, smoking, obesity, sedentary lifestyle, and stress Source: Diario Libre. This underscores the importance of interventions like diet, exercise, and stress management—including laughter.

Both articles agree that incorporating laughter into daily life is a simple, enjoyable way to support cardiovascular health.
