Watching a film that makes you laugh is good for your heart, according to a study.
Researchers found watching a movie or programme that produces laughter has a positive effect on vascular function and is opposite to that observed after watching a war or horror film that causes mental stress.
In the study volunteers watched segments of a funny film – such as There’s Something About Mary starring Cameron Diaz – on one day and on another day watched the opening segment of the stressful war film Saving Private Ryan.
Lead investigator Dr Michael Miller from the University of Maryland School of Medicine in the U.S. said that when the volunteers watched the stressful film, their blood vessel lining developed a potentially unhealthy response called vasoconstriction, reducing blood flow.
