A new study conducted by researchers from the University of Maryland suggests that watching a comedy movie is good for health since laughter has a positive effect on the cardiovascular function.
Researchers led by Dr Michael Miller conducted a study where in volunteers were made to watch a funny clip from the film "There's Something About Mary" while they also watched a serious clip from another film "Saving Private Ryan".
The researchers scanned the blood flow in the volunteers while watching the clips and found that watching a serious movie increased the mental stress and thereby caused a condition known as vasoconstriction wherein the muscular walls of the veins contracted and reduced the blood flow.
"The take-home message here is that laughter is great for your heart. The magnitude of change we saw in the endothelium after laughing was consistent and similar to the benefit we might see with aerobic exercise of statin use", Dr Miller said.
