In his play Feeling Afraid As If Something Terrible Is Going To Happen, playwright Marcelo Dos Santos gives his audience plenty of laughs as they consider what their lives would be without laughter. In a world increasingly mediated by data and diagnostics, the idiom “laughter is the best medicine” seems quaint and naive, nothing more than a pop-psychology platitude. Ever-expanding discoveries in mental health care and pharmaceutical remedies seem to dwarf the notion that simple, ordinary, and free laughter holds genuine medicinal power. Yet science is circling back to what philosophers, playwrights, and jesters have known for centuries: laughter heals.
Laughter activates multiple regions of the brain: the prefrontal cortex (which processes social understanding), the limbic system (emotional processing), and the motor areas (which coordinate the physical act of laughing). When we laugh, our bodies release a cocktail of chemicals—dopamine, endorphins, and serotonin—that collectively reduce stress, relieve pain, and improve mood.
Dr. Lee Berk, a preventive care specialist at Loma Linda University, has conducted several studies over the past two decades exploring the biochemistry of laughter. His studies show that laughter can reduce the body’s inflammatory response, lower blood pressure, and even improve memory. In one experiment, subjects who watched a humorous video showed measurable improvements in learning ability, memory retention, and stress hormone levels. Cortisol levels drop, easing stress and relaxing the body. Blood vessels dilate, improving circulation. Even the immune system responds; his research shows that after bouts of genuine and spontaneous laughter (scientifically coined “mirthful laughter”), there are increased levels of “killer” cells (specialized white blood cells) and enhanced activity of T-cells. In other words, a good laugh doesn’t just make someone feel better—it biologically strengthens a person's ability to fend off illness.
However, not all laughter is therapeutic. There is the nervous laugh, the mocking laugh, the forced chuckle. Not all humor aims to heal: Some wounds are too fresh, some jokes too sharp. Healing, mirthful laughter—what some researchers distinguish as “Duchenne laughter,” named after the 19th-century neurologist Guillaume Duchenne—is spontaneous, involuntary, and often social. It’s this kind of laughter that heals the body, deepens relationships, enhances empathy, and rewires a person's perception of adversity. But in the hands of a skillful comedian—an artist who understands the weight of what they carry—laughter becomes a method of survival and communion.
Some comedians are artisans of Duchenne laughter, carefully crafting moments of collective catharsis and relief. Often seen as jesters, provocateurs, or misfits, their position as healers is frequently overlooked. Yet there is something undeniably medicinal in what they do. Beyond the physical, laughter holds psychological power. It disrupts patterns of anxiety and grief. It reframes trauma, if only for a moment.
Viktor Frankl, a Holocaust survivor and psychiatrist, once wrote of the necessity of humor even in concentration camps—it was, he said, one of the “soul’s weapons in the fight for self-preservation.” Psychologically, laughter offers perspective. It momentarily lifts people above their suffering. It is not a denial of pain, but an acknowledgement of it—wrapped in the disarming clothes of comedy. Neuroscientific research supports the idea that humor enables cognitive reframing—the ability to reinterpret a situation in a way that changes its emotional impact. When a comedian jokes about depression, divorce, or dysfunction, they don’t necessarily trivialize the pain—they reframe it. This mechanism can be deeply therapeutic not only for the performer but also for the audience, who might see their own experiences mirrored in a more manageable, even laughable, light.
Comedy takes the raw material of human suffering— failure, injustice, despair—and fights against it through laughter. Not because the pain isn’t real, but because naming it and laughing at it empowers and inspires resilience. Unlike spontaneous laughter—slipping on a banana peel or being tickled—humor crafted by comedians in this mode is a social prescription, specifically constructed and timed to speak to the suffering they, and their audiences, experience. They serve as emotional cartographers, mapping out the absurdity and struggle within daily life, and guiding their audience through the thicket of suffering with wit as their compass.
Comedians have long known that there is a symbiotic relationship between pain and laughter. Behind many comedians lies a complex personal landscape—depression, trauma, addiction. Their laughter is often hard-won. And perhaps that is why it resonates so deeply. Robin Williams, a performer who wrestled with personal demons throughout his life, said, “Comedy is acting out optimism.” Hannah Gadsby, in her groundbreaking special Nanette, blurred the line between comedy and confession, showing how humor can both mask pain and liberate us from it. Richard Pryor, performing after his recovery from setting himself on fire during a drug binge, transformed personal devastation into raw, cathartic truth. These are not just performances—they are vulnerable, surgical procedures which expose and soothe the soul.
In hospitals and hospices, professional clowns and humor therapists use laughter to ease pain and fear. “Laughter therapy” is now an established practice in many care settings, including cancer wards, dementia units, and psychiatric hospitals. According to the NIH, clinical studies have shown that patients undergoing cancer treatment, for example, report decreased pain perception and improved mood after participating in laughter sessions. Institutions like UCLA and the Mayo Clinic discovered that patients who engage in regular laughter therapy report lower pain levels, improved mood, and greater resilience in treatment.
Still, the role of professional comedians goes beyond structured interventions. Comedy clubs, late-night specials, even stand-up clips on TikTok—all act as decentralized clinics of relief. The digital age has turned comedians into on-demand healers, offering doses of laughter in timelines thick with tragedy and uncertainty. In 2020, during the height of the COVID-19 pandemic, online comedy skyrocketed in popularity, serving as a collective coping mechanism. In a time of physical distancing, humor kept us emotionally tethered.
So, while laughter cannot replace antibiotics or surgery, its benefits are not merely metaphorical. In the alchemy of healing, joy is not a luxury—it is an essential force. And comedians, with their brave vulnerability and razor-sharp observation, are among its most reliable deliverers. Laughter doesn’t just feel good—it does good. And while researchers chart neurotransmitters and hormonal shifts, comedians continue their sacred work, walking into darkness, bearing the torch of laughter, lighting the way for the rest of us.
