It might not replace sleep, exercise or a healthy diet, but laughter does more for your health than you think.
Whether it’s just a funny text from a friend or laughing so hard you can barely breathe, those moments can have a real impact on both your mind and body. And when life gets stressful, they matter even more.
“It often flies under the radar, but laughter plays an important role in emotional and physical health,” says Ila Sabino, PhD, psychologist and program manager of the Division of Health Psychology at the Institute of Living. “Laughter helps reduce stress, improves social connection and can even have a positive impact on your body.”
Here’s why laughter deserves a little more credit.

1. Laughter helps lower stress hormones
Stress has a way of building quietly throughout the day. Emails pile up, schedules get packed and before long, your body is stuck in a constant state of tension.
“Chronic stress affects nearly every system in your body,” says Dr. Sabino. “When stress hormones remain elevated for long periods of time, you may experience fatigue, irritability, headaches, poor sleep and difficulty concentrating.”
Enter: Laughter.
Studies have shown that laughing can reduce cortisol and adrenaline levels and help with relaxation. Even a few minutes of genuine laughter can ease muscle tension and improve your mood.
“It’s one of your body’s natural ways of resetting,” Dr. Sabino adds.

2. It can improve your mood
There’s real science behind it. When you laugh, your brain releases chemicals that support mood and emotional well-being.
“Laughter stimulates the release of endorphins, which are chemicals associated with pleasure and positive feelings,” Dr. Sabino says. “That’s why humor can be such a relief during stressful situations.”
That doesn’t mean you should cancel therapy and start watching more comedy. But laughter can be a great tool for emotional resilience. Watching something funny, spending time with people who make you laugh or simply finding moments of humor throughout the day can all help support mental health.
“Humor helps create emotional distance from stress,” Dr. Sabino adds. “Sometimes it just gives you a much needed chance to breathe.”

3. Laughing with other people strengthens connection
The most important thing about laughter has nothing to do with the joke itself. It’s the connection that comes with it.
“Social connection is a major factor in overall health,” says Dr. Sabino. “People tend to feel less isolated and more supported when they share positive experiences with others.”
Think about it: some of the best laughs happen during conversations, family dinners, road trips or random moments with friends. Those shared experiences help strengthen relationships and create a sense of belonging, which can support both emotional and physical health over time.
“Laughter creates an opportunity for bonding,” Dr. Sabino adds.

4. Your heart may benefit, too
Laughter isn’t just good for your soul. Your cardiovascular system benefits from it too.
“When you laugh, there’s often a temporary increase in heart rate and oxygen intake followed by a period of relaxation,” Dr. Sabino says. “That pattern may help with circulation and blood vessel function.”
Some research suggests laughter can also help improve blood flow and reduce physical tension in the body. While it’s not a substitute for healthy habits like exercise or nutrition, it still helps.
“Small stress-relieving habits add up over time,” Dr. Sabino adds. “Laughter is one more tool that may help support heart health indirectly through stress reduction.”

5. It can help you cope during difficult times
Not every laugh is about pure happiness. Sometimes humor is a way to navigate uncertainty or grief.
“Humor can be a valuable coping mechanism,” says Dr. Sabino. “It doesn’t erase difficult situations, but it can make them feel more manageable.”
That’s why people tend to laugh during stressful family gatherings or hard conversations. Humor creates moments of relief when emotions feel too heavy to carry.
“Being able to laugh during hard times doesn’t mean someone isn’t taking things seriously,” Dr. Sabino adds. “Often, it’s a sign of resilience.”

6. Laughter can encourage mindfulness
One unexpected benefit of laughter? It tends to pull people into the present moment.
“When you’re laughing, you aren’t busy thinking about tomorrow’s to-do list or yesterday’s embarrassing moments,” says Dr. Sabino. “For a moment, you’re fully engaged in the present.”
That mental break matters, especially in a world filled with constant distractions. Humor can create a pause from overthinking and offer a mental reset.
“Even short moments of joy and presence can support emotional well-being,” Dr. Sabino adds. “People don’t always realize how valuable those small moments are.”

7. You may need more laughter than you think
Somewhere between adulthood, finances and endless chores, it’s easy for fun to fall to the bottom of the priority list.
“Adults often underestimate how important playfulness and humor still are,” says Dr. Sabino. “People become so focused on productivity that they forget joy is also part of health.”
That means making room for more moments that feel light and enjoyable:
- Watching a funny movie
- Calling a friend who makes you laugh
- Listening to comedy podcasts
- Playing games with family
- Spending time around people who feel uplifting
Laughter won’t solve every health problem. But it can help people feel more connected, less stressed and emotionally healthier along the way.
“Health is about more than lab results and exercise routines,” says Dr. Sabino. “Mental and emotional well-being matter too, and laughter is one piece of that bigger picture.”
