The Surprising Science Behind Laughing


Laughing is a universal expression of joy, surprise, and even nervousness. But beyond just being a reflexive reaction, scientists are beginning to uncover the surprising science behind why we laugh.

Humans aren’t the only animals that laugh—both chimpanzees and rats have been found to produce a chuckle-like sound in response to tickling. And it’s not just a matter of copying us—scientists believe that the act of laughing itself serves an evolutionary purpose.

Laughter is a form of social bonding. Studies have found that when we laugh with others, endorphins are released, which can create a feeling of connection and trust between two people. This is why it’s often said that “laughter is the best medicine”—it helps to bring people closer together and reduce stress and anxiety.

This connection between laughter and social bonding is so strong that studies have shown that even just hearing someone else laugh can lead to us feeling more comfortable and trusting with that person.

The science behind why something is funny is less clear. Studies have shown that there’s a certain type of humor that makes us laugh the most—incongruity. This type of humor works by presenting us with something unexpected that goes against our expectations. For example, a joke about a man walking into a bar with a giraffe is funny because it’s unexpected.

It’s also believed that laughter can help us process and understand complex information. Studies have found that when people are presented with a humorous story or joke, they are better able to recall the details of the story even hours later.

The science behind laughter is still a relatively new field of study, but it’s clear that it’s much more than just a reflexive response. Laughing is an important part of our social interactions and helps us process difficult ideas and situations. The next time you find yourself laughing, remember that there’s more to it than just feeling good—it’s helping to strengthen your bonds with others and broaden your understanding of the world around you.
