Why Laughter is the Best Medicine

Explore the healing benefits of laughter

You’ve probably heard the saying, "Laughter is the best medicine." And it’s true! Studies show laughter has lots of health benefits — with no side effects. Understanding the positive impacts of laughter can deepen your appreciation for this natural remedy.

"There’s no downside to laughter,” says Michael James Sass Jr., DO, a primary care physician at Geisinger Lewisburg. And a few minutes of mirth every day has a definite upside, he adds: “You may see many health benefits.”

The health benefits of laughter

As well as being enjoyable, laughter is beneficial for your well-being.

"This 'medicine' is quick, free and accessible anywhere, with no negative side effects," says Dr. Sass. "Besides, it's fun."

Here are some reasons why laughter is the best medicine.

Releases endorphins and decreases pain

Ever wondered why laughter feels so good? When you laugh, your body produces endorphins, which are chemicals that promote feelings of happiness and well-being.

Dr. Sass explains, "The release of endorphins can heighten the body’s natural pain-relief mechanisms, which can be especially helpful for managing chronic discomfort and enhancing overall mood."

In fact, studies have found funny movies could increase your pain tolerance and decrease anxiety.

Stress reduction

The surge of endorphins not only elevates mood but helps alleviate stress. "Laughter serves as an effective coping strategy when facing stress," says Dr. Sass. "A hearty laugh can set a positive tone at the start of your day and help you unwind by day's end."

This is true for all ages. Nursing home patients showed 20% less agitation after “humor therapy” — a benefit equal to that of medication — without any side effects.

Immune system support

When you laugh, you lower the production of stress hormones like cortisol. "This can activate infection-fighting cells, helping your body combat stress-induced reactions and promote overall health," Dr. Sass says.

Natural killer cells — a specialized type of white blood cell that attacks abnormalities like infection and cancer cells — become more active after we laugh.

Enhanced blood circulation and breathing

Ever laughed so hard it took you a while to catch your breath? That’s because laughter encourages deeper breathing, which increases oxygen intake and improves blood circulation. Better oxygen flow supports healthy cell and organ function. Your heart pumps more blood and your blood vessels dilate.

Cracking up is almost like a small, low-impact workout. People who laugh regularly have fewer heart arrhythmias and a lower risk of heart attack. It may even help those with asthma and breathing problems.

Muscle relaxation

Having a good laugh eases tension. Just a few minutes of hearty laughter can promote relaxation throughout your body.

Helps regulate blood sugar

At mealtime, watch a funny show or talk with someone who makes you laugh. Your glucose levels won’t tend to spike as high after you eat.

“A good comedy won’t treat diabetes, but it can slightly dampen the crazy sugar spike after you eat birthday cake,” says Dr Sass.

Improved mood and brainpower

It’s not surprising laughter can lighten your mood, but it’s also found to improve self-esteem and the state of mind of people with cancer. Plus, research has shown that laughter can help older adults learn better and remember things longer.

Fake laughter can be as healthy as the real thing

A good belly laugh sends messages on a different path in your nervous system than the fake giggle you give after your boss tells a joke. But surprisingly, both can have benefits.

“Both exercise and fake laughter have been found to decrease depression symptoms by about the same amount,” says Dr. Sass.

Incorporating more laughter into your day

The health benefits of laughter are so well documented, some doctors even prescribe a good giggle to their patients. You can:

1. Watch something funny

Whether it’s your favorite sitcom, a stand-up comedy routine or silly animal videos, set aside time for something that brings you joy. You could even turn this into a weekly ritual: Make a snack and settle into your favorite spot for some lighthearted entertainment.

2. Share a joke

Spread some cheer by sharing a classic dad joke or a few good (or bad) puns. In need of a laugh? Chat with a friend and rehash some favorite humorous memories.

3. Spend time with pets

Animals have an innate ability to make us laugh. So play with your pet, whether it's a game of chase or a laser pointer session — or just enjoy watching their antics.

4. Host a dance party

There’s nothing quite like an unplanned dance party to spark joy. Play your favorite tunes and let loose, encouraging family members to join in and dance with abandon.

5. Connect with friends

When you’re in need of a good laugh, reach out to a friend who tickles your funny bone. Whether through a video call or lighthearted text messages, reminiscing about funny moments can boost your spirits.

Embrace optimism

"Instead of dwelling on stressful situations or minor mishaps, cultivate the habit of finding humor in these instances,” says Dr. Sass. “Viewing life through a humorous lens can transform your perspective and alleviate stress. And if you’re facing challenges or chronic health issues, it’s especially important to seek laughter."
