Laughter may be as good for us as jogging. American researchers found that there was increased blood flow when participants in a new study watched a movie that made them chuckle.
Twenty healthy volunteers in the US took part in the experiment which found that the circulation boost was similar to what results from aerobic exercise.
Professor Michael Miller of Maryland University, led a team of scientists who observed participants before and after they had watched clips from a comedy film, such “ Something about Mary,” and then a distressing film, like “Saving Private Ryan.”
Measurements of the blood flow in the arms brachial artery, revealed blood vessel dilatation was increased with the comedy film more than for the much more serious film. The research results are being published next month.
