Oddly enough, we’ve all had our moments when an awkward or tense situation prompted us to laugh— an unrequited response to a rather serious topic. Are these fits of laughter just nervous reactions or is there a psychological force at work? 

The Science of Nervous Laughter

In general, laughter discharges endorphins throughout our body to relieve stress and relax. Nervous laughter has the same function, allowing individuals to release anxiety and reach a state of peacefulness. In a study done by Yale psychology researcher Dr. Oriana Aragon, suggests nervous laughter may be “a form of self regulation.” Nervous laughter also serves as an incongruous emotion, or an emotion that mismatches one's internal feelings and outward expressions. Aragon lists the benefits of experiencing incongruous emotions in her study, one of which is reaching an equilibrium or balance between positive and negative stimuli. As uncomfortable as it may be, expressing the opposite emotion has a “dampening effect” and the ability to restore the even distribution of both polar opposite emotions. 

Margaret Clark, a professor of psychology at Yale University and co-author of the study “Dimorphous Expressions of Positive Emotion,” suggests that overwhelming emotions of sorrow or uneasiness raise a person’s emotional limit that inhibits mental functions. By laughing, we achieve emotional homeostasis, which allows us to have a better grip on our psychological, social, and cognitive behaviors. Both Aragon’s and Clark’s findings indicate that laughter aids in regulating our emotional state in tense situations . 

Other studies suggest that nervous laughter can embody a defense mechanism against trauma. In the post “Why We Laugh” (2011), Alex Lickerman M.D. suggests nervous laughing can unconsciously protect ourselves from trauma. By confronting past experiences with humor, we are signaling to our bodies that the horrible thing we encountered is not as horrible as it seems and replace the pain with a more positive emotion. Moreover, it can be a social cue to others by indirectly communicating to others that we have survived it and are no longer struggling to move on with our lives. 

Learning to Regulate Emotional Responses

Even though laughter is an integral part of human behavior, it may be seen as inappropriate in some settings. Meditation and mindfulness can help reduce the impact of the impulse to laugh and help gain a deeper understanding of the triggers that onset those reactions. Yoga, breathing exercise, and art or music therapy can help control intense emotions. Licensed therapists specializing in cognitive behavioral therapy can also target severe anxiety and the emotional cues that lead to symptoms like nervous laughter. While the response is completely natural, if it becomes a disruption such resources may be helpful to avoid ill-timed laughing fits.

More Than Just an Awkward Moment

The next time you catch your friend flooded with chuckles for no reason, do not be quick to judge. It is most likely their body’s inherent reaction to coping or handling an emotional situation.
