It seems the benefits of laughter has no end.
Due to the movement of the diaphragm when we laugh heartily there is an increase in blood flow around the body – perfect for stimulating healing.
“It appears that laughter has other beneficial effects that could stimulate healing of venous ulcers and other types of chronic wounds. Michael Miller, MD, FACC, FAHA, professor at the University of Maryland School of Medicine in Baltimore, reported that laughter results in vasodilatation of arteries. He showed that arterial vasodilatation was significantly higher in patients who had seen a funny movie and experienced laughter compared to patients in a control group and those who had seen an anxiety-producing movie.3He proposed that laughter stimulates the hypothalamus and pituitary gland in the brain causing release of ß-endorphins. These activate the µ-3 receptor in the vascular endothelium, resulting in nitric oxide production. Nitric oxide causes vessel dilatation, reduced platelet aggregation, and decreased inflammation.4 All of these end results would be beneficial for anyone with a chronic wound, especially a venous ulcer.”
