The University of Maryland did a very interesting study. They took 2 groups of people and had one group watch a drama, "Saving Private Ryan" and the other, a comedy, "There's Something about Mary". After the movies, the blood vessels of those who watched the comedy behaved normally, expanding and contracting. Those who watched the drama, however, had tense blood vessels, restricting flow.
So, to answer my friends question...YES! Laughter likely does indeed help to keep our hearts healthy. More so than just laughter, it is probably an overall positive attitude and decreased stress levels that allow us to laugh, and this is likely the reason for the healthier heart. (But don't think that you can just go see a comedy instead of going to the gym....it's not THAT closely related!).
Thanks for the great idea for the post! Now, can you tell me what the heck "laughter yoga" is?!
Until next time....keep smiling and laughing!
