Professor Michael Miller, a cardiologist at the University of Pennsylvania, believes that regular laughter can provide benefits to the heart and blood vessels comparable to moderate physical activity. This is reported by Medical Xpress.
The expert notes that laughter should be seen as an integral part of a healthy lifestyle, alongside advice to exercise regularly three to five times a week. During laughter, endorphins are actively produced in the body. They trigger the synthesis of nitric oxide, which helps to dilate blood vessels and improve blood flow, reducing the load on the cardiovascular system.
Observations show that its effect is not limited to the heart. Laughter also positively impacts the immune system: the number of protective cells in the blood increases, enhancing the overall resistance of the body.
The cardiologist also emphasizes an important nuance that even intentional artificial laughter can yield similar results. The fact is that it engages the same respiratory and muscular reactions as spontaneous laughter, thereby initiating similar physiological processes.
