Why Do We laugh
Laughter is part of the universal human vocabulary. All members of the human species understand it. Unlike English or French or Swahili, we don’t have to learn to speak it. We’re born with the capacity to laugh.
Very little is known about the specific brain mechanisms responsible for laughter. But we do know that laughter is triggered by many sensations and thoughts, and that it activates many parts of the body.
Philosopher John Morreall believes that the first human laughter may have begun as a gesture of shared relief at the passing of danger. And since the relaxation that results from a bout of laughter inhibits the biological fight-or-flight response, laughter may indicate trust in one’s companions.
Many researchers believe that the purpose of laughter is related to making and strengthening human connections. “Laughter occurs when people are comfortable with one another, when they feel open and free. And the more laughter [there is], the more bonding [occurs] within the group,” says cultural anthropologist Mahadev Apte. This feedback “loop” of bonding-laughter-more bonding, combined with the common desire not to be singled out from the group, may be another reason why laughter is often contagious.

Why is that funny (or not funny, as the case may be)? Human beings love to laugh, and the average adult laughs 17 times a day. Humans love to laugh so much that there are actually industries built around laughter. Jokes, sitcoms and comedians are all designed to get us laughing, because laughing feels good. For us it seems so natural, but the funny thing is that humans are one of the only species that laughs. Laughter is actually a complex response that involves many of the same skills used in solving problems.
Laughter is a great thing — that’s why we’ve all heard the saying, “Laughter is the best medicine.” There is strong evidence that laughter can actually improve health and help fight disease. In this article, we’ll look at laughter — what it is, what happens in our brains when we laugh, what makes us laugh and how it can make us healthier and happier. You’ll also learn that there’s a tremendous amount that no one understands yet.

Most agree that we laugh when we find something to be humorous, yet different reasons exist for what we find to be humorous. Additionally, different things are humorous to us at different stages of life.
The first is a set of gestures, and the second is the production of sound. The brain forces to conduct both responses simultaneously. From a physiological standpoint, a “sensor” in the brain responds to laughter by triggering other neural circuits in the brain, which, in turn, generate more laughter.

The answer may seem obvious: We laugh when we perceive something funny. But the obvious answer is not correct, at least most of the time.
“Most laughter is not in response to jokes or humor,” says Robert R. Provine, a professor of psychology and neuroscience at the University of Maryland Baltimore County. Provine should know. He has conducted a number of studies of laughter and authored the book Laughter: a Scientific Investigation. One of his central arguments is that humor and laughter are not inseparable.

But laughter has power — the power to energize the hum-drum, add levity to the everyday blah-blah-blah. Laughter carries such a social connection that it’s a mating ritual, a way to bond. Studies suggest that laughter may boost our health.
Our all-too-human laughter sets us — and our close cousins, the primates — apart from all other species that roam our planet, says Robert R. Provine, PhD, a behavioral neurobiologist at the University of Maryland in Baltimore.
