“Humor is infectious. The sound of roaring laughter is far more contagious than any cough, sniffle, or sneeze. When laughter is shared, it binds people together and increases happiness and intimacy. Laughter also triggers healthy physical changes in the body. Humor and laughter strengthen your immune system, boost your energy, diminish pain, and protect you from the damaging effects of stress. Best of all, this priceless medicine is fun, free, and easy to use.

Laughter is strong medicine for mind and body

Laughter is a powerful antidote to stress, pain, and conflict. Nothing works faster or more dependably to bring your mind and body back into balance than a good laugh. Humor lightens your burdens, inspires hopes, connects you to others, and keeps you grounded, focused, and alert.

With so much power to heal and renew, the ability to laugh easily and frequently is a tremendous resource for surmounting problems, enhancing your relationships, and supporting both physical and emotional health.

Laughter is good for your health

• Laughter relaxes the whole body. A good, hearty laugh relieves physical tension and stress, leaving your muscles relaxed for up to 45 minutes after.
• Laughter boosts the immune system. Laughter decreases stress hormones and increases immune cells and infection-fighting antibodies, thus improving your resistance to disease.
• Laughter triggers the release of endorphins, the body’s natural feel-good chemicals. Endorphins promote an overall sense of well-being and can even temporarily relieve pain.
• Laughter protects the heart. Laughter improves the function of blood vessels and increases blood flow, which can help protect you against a heart attack and other cardiovascular problems.

Laughter and humor help you stay emotionally healthy

Laughter makes you feel good. And the good feeling that you get when you laugh remains with you even after the laughter subsides. Humor helps you keep a positive, optimistic outlook through difficult situations, disappointments, and loss.

More than just a respite from sadness and pain, laughter gives you the courage and strength to find new sources of meaning and hope. Even in the most difficult of times, a laugh–or even simply a smile–can go a long way toward making you feel better. And laughter really is contagious—just hearing laughter primes your brain and readies you to smile and join in the fun.

The link between laughter and mental health

• Laughter dissolves distressing emotions. You can’t feel anxious, angry, or sad when you’re laughing.
• Laughter helps you relax and recharge. It reduces stress and increases energy, enabling you to stay focused and accomplish more.
• Humor shifts perspective, allowing you to see situations in a more realistic, less threatening light. A humorous perspective creates psychological distance, which can help you avoid feeling overwhelmed.

The social benefits of humor and laughter

Humor and playful communication strengthen our relationships by triggering positive feelings and fostering emotional connection. When we laugh with one another, a positive bond is created. This bond acts as a strong buffer against stress, disagreements, and disappointment.

Laughing with others is more powerful than laughing alone

Shared laughter is one of the most effective tools for keeping relationships fresh and exciting. All emotional sharing builds strong and lasting relationship bonds, but sharing laughter and play also adds joy, vitality, and resilience. And humor is a powerful and effective way to heal resentments, disagreements, and hurts. Laughter unites people during difficult times.

Incorporating more humor and play into your daily interactions can improve the quality of your love relationships— as well as your connections with co-workers, family members, and friends. Using humor and laughter in relationships allows you to:

• Be more spontaneous. Humor gets you out of your head and away from your troubles.
• Let go of defensiveness. Laughter helps you forget judgments, criticisms, and doubts.
• Release inhibitions. Your fear of holding back and holding on are set aside.
• Express your true feelings. Deeply felt emotions are allowed to rise to the surface.

Bringing more humor and laughter into your life

Laughter is your birthright, a natural part of life that is innate and inborn. Infants begin smiling during the first weeks of life and laugh out loud within months of being born. Even if you did not grow up in a household where laughter was a common sound, you can learn to laugh at any stage of life.

Begin by setting aside special times to seek out humor and laughter, as you might with working out, and build from there. Eventually, you’ll want to incorporate humor and laughter into the fabric of your life, finding it naturally in everything you do.

Here are some ways to start:

• Smile. Smiling is the beginning of laughter. Like laughter, it’s contagious. Pioneers in “laugh therapy,” find it’s possible to laugh without even experiencing a funny event. The same holds for smiling. When you look at someone or see something even mildly pleasing, practice smiling.
• Count your blessings. Literally make a list. The simple act of considering the good things in your life will distance you from negative thoughts that are a barrier to humor and laughter. When you’re in a state of sadness, you have further to travel to get to humor and laughter.
• When you hear laughter, move toward it. Sometimes humor and laughter are private, a shared joke among a small group, but usually not. More often, people are very happy to share something funny because it gives them an opportunity to laugh again and feed off the humor you find in it. When you hear laughter, seek it out and ask, “What’s funny?”
• Spend time with fun, playful people. These are people who laugh easily–both at themselves and at life’s absurdities–and who routinely find the humor in everyday events. Their playful point of view and laughter are contagious.
• Bring humor into conversations. Ask people, “What’s the funniest thing that happened to you today? This week? In your life?” Helpguide.org, Laughter is the best medicine, Paul E. McGhee, PH.D., author.
