Researchers are learning more and more about humor’s effects on our physical health and overall well-being.

In particular, there is a strong connection between amusement, cheerfulness, and resilience. It’s easy to strengthen your sense of humor; laughter is contagious.


If you have to explain it…it probably isn’t funny. Some scientists have taken on the unfunny task of researching and explaining humor and are learning the reasons behind what we already knew: laughing makes us feel better. Humor is a whole mind-body and social experience; it’s a cognitive ability that gets our emotions and our bodies involved in the act, and it also connects us to other people.

Cognitively, to find things funny we need to be able to shift perspective, perceive incongruities and paradoxes, and be surprised and delighted by the unexpected—the punch line. This causes us to switch into a playful, rather than a serious, frame of mind. When we are amused, we are in a state of observation, which gives us a bit of psychological space or distance from our circumstances.

, the unique positive emotion associated with humor is called mirth. Mirth can range in intensity from mild amusement to side-splitting hilarity. Like other emotions, mirth produces changes in the biochemistry of our brain and hormone system. Laughter is the nonverbal behavior that communicates to others that we are experiencing the emotion of mirth. The unique sounds of laughter also arouse feelings of mirth in listeners, causing them to begin laughing as well.

Physiologically, when we’re experiencing the emotion of mirth, there is an increase in dopamine activity in the pleasure center in the limbic system of the brain. This is the “reward center” of the brain that is activated by other positive emotions and activities. During times of mirth, the brain also produces endorphins, which raise our pain threshold and can reduce pain we may already be feeling. Mirth also triggers a relaxation response, causing our legs and arms to become weak. Have you ever laughed so hard that you couldn’t keep standing and fell to the floor?

Socially, humor is usually shared with others—we laugh most often when we’re with other people, and laughter is just as contagious as yawning. Other people are also the focus of most humor – we laugh at the funny things people say and do. Sharing laughs can help us bond with family and friends. And it can make us more attractive. Studies have shown that men who produce humor are more attractive to women—and men are more attracted to women who laugh at their jokes.

Humor is beneficial to us when it is what researchers call “affiliative” or “self-enhancing.” Affiliative humor is amusing and being amused by others. Self-enhancing humor is maintaining an amused outlook on life; being able to laugh at yourself (self-deprecating humor) and see the humor in your circumstances.

The dark side of humor
Aggressive humor is contemptuous, hostile, and manipulative. It is used to display a lack of respect and to hurt others. Self-defeating humor is the use of humor to amuse others at one’s own expense in a self-disparaging way. This can be a defense mechanism for low self-esteem, depression, and anxiety. Humor can also be used to mask or avoid something that is wrong and needs attention. Forms of “humor” such as sarcasm, schadenfreude (delighting in another’s misfortune), hurtful teasing, and attacks based on race, sex, ethnicity, religion, or other aspects of people’s identity tear apart the social fabric and lead to reduced well-being among individuals and communities.

Common misconceptions

Some people just don’t have a sense of humor.
Humor is a cognitive ability, and there are conditions that can interfere with people’s ability to “get” jokes. Humor is also extremely dependent on context and culture. It can be hard to get the humor when you are in an unfamiliar place or group. Humor also depends on feeling comfortable and safe enough to “let down your guard” and delight in the absurd. People who seem to not have a sense of humor may simply not be in the right setting to let loose. Most people can cultivate a sense of humor, especially when they are with other people with whom they feel comfortable.

Laughter is the best medicine; it cures disease.
There is very little evidence that laughter itself cures disease, and it certainly shouldn’t replace medical care. However, there is evidence that laughter promotes social connections and resilience, and that it reduces stress, anxiety, and pain. All of this can promote well-being and recovery.

The pun is the lowest form of humor.
This is not a question that science is able to answer, but it has been hotly debated by funny people for centuries. Samuel Johnson defined puns as the lowest form of humor. But the list of funny people who can’t resist them is long: Shakespeare (about 3,000 of them), Queen Elizabeth I, Milton, John Donne, Jonathan Swift, Charles Lamb, James Joyce, Groucho Marx, Ogden Nash, Oscar Wilde, Dorothy Parker, S. J. Perelman, James Thurber, T. S. Eliot, and George Carlin, to name just a few. American humorist Fred Allen weighed in with a verdict: “Hanging is too good for a man who makes puns; he should be drawn and quoted.”
