A paper (Laughter and MIRTH (Methodical Investigation of Risibility, Therapeutic and Harmful)) in the British Medical Journal reviewed the literature on harms arising from laughter and produced a wide-ranging list of laughing-related dangers, from asthma attacks to cerebral tumors. The authors concluded “Laughter is not purely beneficial. The harms it can cause are immediate and dose related, the risks being highest for Homeric (uncontrollable) laughter.”
