Laughter is an incredibly powerful tool for improving both mental and physical health. When we laugh, our bodies release endorphins, which are natural painkillers that can also improve mood. In addition to reducing stress, laughter can also improve circulation, boost the immune system, and promote overall well-being.

The Physical Benefits of Laughter

Laughter has a number of physical benefits. For example, it can help reduce stress hormones, such as cortisol and adrenaline, which can contribute to a range of health problems over time. Laughter can also improve circulation, which can have positive effects on cardiovascular health. Additionally, research has shown that laughter can stimulate the production of antibodies, which can help boost the immune system and improve overall health.

This study published in Complementary Therapies in Medicine aimed to compare the cardiovascular effects of spontaneous and simulated laughter. 72 participants were randomly assigned to one of three interventions – simulated laughter, spontaneous laughter, or a control condition. Heart rate and heart rate variability were monitored continuously throughout the experiment. The study found that simulated laughter resulted in a significantly higher heart rate and lower heart rate variability compared to spontaneous laughter and the control condition. The difference in heart rate was due to the fact that the simulated condition produced more laughter. Laughter leads to increased heart rate and reduced heart rate variability, similar to the effects of exercise.

The Mental Benefits of Laughter

In addition to its physical benefits, laughter also has a number of mental health benefits. Laughter can help reduce anxiety and depression by increasing the production of feel-good chemicals in the brain, such as dopamine and serotonin. Laughter can also help improve mood, increase resilience to stress, and promote a sense of well-being.

This research published in The Tohoku Journal of Experimental Medicine highlights the impact of laughter therapy on mental health, stress, and the immune system. Laughter therapy is a non-pharmacological, alternative treatment that can improve physical, psychological, and social relationships, ultimately enhancing the quality of life. Laughter reduces stress hormones in the blood, decreasing cortisol, epinephrine, growth hormone, and dopamine catabolite levels. It can also alter dopamine and serotonin activity in the brain, which are neurotransmitters involved in mood regulation. Additionally, endorphins secreted by laughter can help alleviate discomfort or depressive moods. As a noninvasive and accessible treatment, laughter therapy is an effective and scientifically supported method to use alone or as an adjuvant therapy for improving mental health.

Social Benefits of Laughter

Laughter is also an important social tool that can help strengthen social bonds and improve relationships. Laughing with others can create a sense of connection and help build trust and rapport. This can be particularly helpful for individuals who may be feeling isolated or lonely.

This research published in the journal Social and Personality Psychology Compass proposes a social functional account of laughter, focusing on the behavioral intentions it conveys and the responses it elicits in recipients. Laughter’s general function is to signal harmless intentions, and within this, three distinct social tasks are identified. First, laughter rewards others’ behavior and reinforces interactions. Second, it eases social tension, signals affiliation, and conveys nonthreat. Third, laughter enforces social norms, negotiates status, and corrects undesirable behavior by conveying dominance or superiority. The study suggests that the acoustic modulations in laughter communicating these intentions follow principles common to both human and nonhuman vocal signaling.

How to Incorporate More Laughter Into Your Life

Incorporating more laughter into your daily routine is easier than you might think. Watching a funny movie or TV show, reading a humorous book or comic, or attending a comedy show are all great ways to promote laughter. Additionally, spending time with friends and loved ones who have a good sense of humor can help increase opportunities for laughter.

  1. Watch or listen to comedy: Find comedians, shows, movies, or podcasts that make you laugh and incorporate them into your daily routine. You can watch a funny movie or sitcom in the evening, listen to a comedy podcast during your commute, or attend live comedy shows for a more interactive experience.
  2. Spend time with funny people: Surround yourself with people who have a good sense of humor and share your taste in comedy. Engage in playful conversations, share jokes or funny stories, and be open to humor in everyday situations.
  3. Practice laughter yoga or join a laughter club: Laughter yoga is a practice that combines laughter exercises with deep breathing techniques to stimulate laughter, even without humor. Join a laughter yoga class or participate in a local laughter club to connect with like-minded individuals and engage in group laughter activities.
  4. Embrace your inner child: Take part in activities that you enjoyed as a child, such as playing games, making silly faces, or engaging in light-hearted fun. Encourage a playful mindset that allows you to laugh at yourself and find humor in mundane situations.
  5. Use humor as a coping mechanism: When faced with stress or challenging situations, try to find humor in them. Laughter can help diffuse tension and provide a fresh perspective. Look for the absurdity in challenging situations or use self-deprecating humor to lighten the mood.
  6. Incorporate humor into your daily routine: Find ways to add laughter to your daily activities, such as reading a funny comic strip, watching a short comedy sketch, or using a humorous screensaver on your computer. These small doses of humor can help brighten your day and foster a more positive outlook.
  7. Participate in improv or comedy classes: Take an improv or comedy class to learn how to think on your feet, create funny situations, and be more spontaneous. These classes can help you develop your sense of humor and improve your ability to find laughter in everyday life.
  8. Use technology to access humor: Utilize social media, websites, and apps to find funny content, such as memes, videos, or jokes. Share them with friends and engage in online humor communities to increase your exposure to laughter-inducing content.
  9. Play with pets: Pets, particularly dogs, can be a great source of laughter with their playful and often humorous antics. Spend time playing with your pet, or visit a dog park to observe other animals and their amusing behaviors.
  10. Cultivate a positive mindset: Develop an attitude of gratitude and focus on the positive aspects of life. When you maintain a positive outlook, you are more likely to find humor and reasons to laugh in your daily experiences.


Laughter is a powerful tool for improving both mental and physical health. By reducing stress hormones, improving circulation, boosting the immune system, and promoting feelings of well-being, laughter can have a range of positive effects on overall health. So take some time to laugh each day and reap the many benefits that laughter has to offer.
