Can Laughing More Improve Your Health? Here’s What to Know

Most adults are not scheduling more time to laugh. Between work, bills, family obligations, and other responsibilities, joy tends to slip toward the bottom of the to-do list, somewhere below the dentist appointment you’ve been rescheduling, and above the home project you’ll get to eventually. That ranking may be worth reconsidering.

Recent health explainers from Mayo Clinic and St. Vincent’s Institute of Living suggest that laughter may offer something people routinely underestimate: a genuine, low-cost physiological reset that can ease physical tension, lift mood, and strengthen connections between people.

For anyone already carrying work stress, digital fatigue, or the general weight of adult life, the case for making more room for laughter is more substantive than it probably sounds.

This Is What a Real Laugh Does to You

The physical effects kick in fast, and they’re more interesting than most people realize.

When you laugh hard enough to mean it, your body takes in a rush of oxygen-rich air. Mayo Clinic explains that this stimulates the heart, lungs, and muscles and prompts the brain to release endorphins, chemicals tied to pleasure and relief. From there, the stress response activates briefly, then cools: heart rate and blood pressure tick up, then settle back down, leaving the body mildly relaxed.

Along the way, laughter may aid circulation and help ease muscle tension, chipping away at some of the physical strain stress tends to leave behind. In addition, laughter may lower cortisol, the hormone most associated with prolonged stress.

“Laughter stimulates the release of endorphins, which are chemicals associated with pleasure and positive feelings,” says Ila Sabino, PhD, a psychologist in the Division of Health Psychology at the Institute of Living at St. Vincent’s. “That’s why humor can be such a relief during stressful situations.”

The Part That Involves Other People

Laughter rarely happens in isolation, and some of its most meaningful effects may depend on who’s in the room.

Real laughter, the kind that passes between people without trying, creates something that more deliberate forms of social effort can struggle to manufacture. Mayo Clinic notes that laughter can help people connect with others. Dr. Sabino adds that shared positive experiences tend to make people feel less isolated and more supported.

There’s also a mindfulness dimension that doesn’t get talked about much. Laughter pulls people out of their own heads in a way that’s hard to replicate. “When you’re laughing, you aren’t busy thinking about tomorrow’s to-do list or yesterday’s embarrassing moments,” Dr. Sabino adds. “For a moment, you’re fully engaged in the present.”

Even brief moments of that kind of presence, she adds, can support emotional well-being in ways most people don’t fully register.

Adults May Be Undervaluing Joy

There’s a real cost to treating humor as optional, and a psychologist who studies this says people do it all the time.

Between professional obligations, household management, and adulthood, humor and playfulness can stop feeling like priorities. Most people don’t reject laughter; they stop making room for it and wait for a window that rarely opens on its own.

Both Mayo Clinic and Dr. Sabino describe humor as a coping tool rather than a way of avoiding difficult experiences. They note that humor can help make challenging situations feel more manageable.

Being able to laugh during stressful or painful periods is not a sign that someone is ignoring what is happening; instead, it can reflect resilience and an ability to adapt.

Small Ways to Make Room for It

Neither source is asking for a lifestyle overhaul. Most of their suggestions are straightforward enough to put into practice this week.

Researchers recommend keeping funny material within easy reach: humorous texts or saved photos, a comedy show you actually look forward to, or even a podcast that reliably makes you laugh during a commute.

The idea is to make access easy enough that humor stops requiring special effort. Spending time with people who genuinely make you laugh is near the top of the list as well. For those who prefer something more structured, laughter yoga offers a class-based option.

What Laughter Won’t Fix

Both studies are clear: laughter complements a healthy life, not a shortcut past one.

Researchers advise anyone dealing with mental health concerns to reach out to a licensed mental health professional.

Laughter does not replace sleep, exercise, or a healthy diet, and it is not a substitute for the habits and supports that actually hold a person together over time.

It is, though, one more accessible tool: low-effort, often social, and available to most people in some form most days.

When stress piles up, do you reach for humor or pull away from it, and has one approach served you better than the other?
