5 Reasons to Laugh More (According to Science)

Do you find rhythmic, involuntary openings of the diaphragm and vibrations of the vocal cords useless? If you do, science disagrees with you. Here are five reasons you should be laughing more, especially today, National Tell-A-Joke Day:

1) More sex
Scientist theorize that women perceive funny men as more intelligent and ultimately better providers, which explains why women are always looking for a sense of humor in their dating profiles.

2) It makes you happy
The physical act of laughing makes you happy. Muscle contractions during laughter release endorphins. Endorphins are the magical brain chemicals that cause runner's high during exercise. It's actually suggested that laughing 100 times is equivalent to 15 minutes on an exercise bike.

3) Laughter helps you poop
The benefits don't stop at rock hard abs. Laughter also helps you poop. Research shows laughter balances blood pressure and improves circulation, which in turn, improves digestion. Kinda puts a whole new spin on poop jokes doesn't it... but let's cut the crap.

4) It boosts your immune system
Do you know laughter can help prevent the common cold? By lowering the amount of cortisol epinephrine in the body, laughter can rejuvenate a tired immune system, meaning you'll have a lower chance of getting sick.

5) Laughter prevents infections.
Laughter kickstarts macrophages, a type of white blood cell that targets invaders like viruses and bacteria.

So please, feel free to continue National Tell-A-Joke day with your involuntary rhythmic convulsions... your body will thank you.
