Of the myriad behaviors that humans exhibit, laughter is perhaps the most uncalled-for action, read involuntary. Researchers have proved that laughter is the most primal and innate action of the human mind and is directly linked to the evolution of the human brain.

The big question, however, is why do we laugh? When we flex those facial muscles to chuckle, it helps our brain release all kind of tension and emotion. It's one of the most harmless way to vent any emotion, be it anger, fear, sadness, boredom, etc.

That's why when people feel down, they immediately reach out for something funny to watch or read   so they can laugh off the negative emotions or tensions away. In fact, that's exactly how the thought "laughter is the best medicine" was coined.

The physiological effects of humor on health is countless. Not only does it shoo away stress, but also boosts the immune system, lowers blood pressure, gives your diaphragm and abdominal, respiratory, facial, leg, and back muscles a workout and keeps life-threatening diseases like cardiac ailments at bay.

With so many advantages, it'll surely pay to flex those muscles often for a hearty laugh!
