“Laughter is the best medicine” — who hasn’t heard this popular adage? But recent discoveries in medicine show that there is some fact to this old saying. Laughter is not a cure for cancer or other degenerative diseases, but doctors and other medical professionals have found that it increases treatment receptiveness in patients. Scientists researching psychoneuroimmunology are discovering that there is a crucial connection between a person’s mind and body. This is particularly manifested by the body’s ability to heal through mental stimulation. Laughter appears to change brain chemistry and boosts the body’s immune system.  Humour therapy aids in healing by promoting good feeling, laughter, and smiles. Sometimes called therapeutic humour, this type of therapy is fast gaining popularity among medical institutions worldwide.
