Laughter is a universal language that transcends barriers, connecting us in moments of joy and lightness. Beyond its ability to uplift our spirits, laughter holds profound healing potential that can enhance our vitality across multiple dimensions – body, mind, and spirit. This week to celebrate International Happiness Week, as well as “National Laughter Day”, this article, we delve into the science-backed benefits of laughter, exploring its effects on various organ systems, and uncovering its transformative impact on holistic well-being. 

The Physiological Benefits of Laughter: 

Cardiovascular System: 

   Laughter acts as a natural cardiovascular workout, stimulating blood flow and promoting heart health. Dr. Michael Miller, a cardiologist at the University of Maryland Medical Center, conducted a study revealing that laughter causes the inner lining of blood vessels to dilate, increasing blood flow and improving circulation. This dilation helps reduce the risk of heart attacks and other cardiovascular issues. As Dr. Miller eloquently puts it, “Laughter, along with an active sense of humor, may help protect you against a heart attack.” 

Respiratory System: 

   Laughter engages the respiratory system, facilitating deeper breathing and oxygenating the body. It strengthens respiratory muscles and clears airways, promoting better lung function. Research conducted by Dr. Lee Berk at Loma Linda University found that laughter enhances the body’s ability to expel residual air and secretions from the lungs, thereby reducing the risk of respiratory infections. 

Immune System: 

   Laughter stimulates the production of immune cells, such as T cells and antibodies, bolstering the body’s defense mechanisms against pathogens. A study published in the Journal of Psychosomatic Research demonstrated that laughter increases the activity of natural killer cells, which play a crucial role in combating viral infections and cancerous cells. 

Endocrine System: 

   Laughter triggers the release of endorphins, neurotransmitters that promote feelings of happiness and alleviate pain. Additionally, it reduces levels of stress hormones such as cortisol and adrenaline, fostering a state of relaxation and well-being. Dr. William Fry, a pioneer in gelotology (the study of laughter), highlights the profound impact of laughter on hormonal balance, stating, “Laughter turns on the endorphins, the body’s natural painkillers, and it also reduces the level of stress hormones.” 

The Psychological Benefits of Laughter: 

Stress Reduction: 

   Laughter serves as a powerful antidote to stress, diffusing tension and promoting relaxation. Dr. Robert Provine, a neuroscientist and laughter researcher, notes that laughter triggers the release of tension-relieving hormones, leading to a state of calmness and emotional balance. He states, “Laughter serves as a reset button, interrupting the cycle of stress and promoting a sense of well-being.”  

Cognitive Function: 

   Engaging in laughter enhances cognitive function by stimulating mental processes and improving memory retention. A study published in the journal Aging demonstrated that adults who engaged in regular laughter exercises experienced significant improvements in cognitive performance, including enhanced memory recall and problem-solving abilities. 

Emotional Well-being: 

   Laughter fosters emotional resilience, enabling individuals to cope with adversity and maintain a positive outlook on life. Dr. Steven Sultanoff, a psychologist specializing in humor therapy, emphasizes the role of laughter in promoting emotional well-being, stating, “Laughter serves as a buffer against stress and helps us navigate life’s challenges with grace and humor.” 

The Spiritual Benefits of Laughter: 

Connection and Unity: 

   Laughter transcends cultural and linguistic barriers, fostering a sense of connection and unity among individuals. It brings people together in moments of shared joy, promoting empathy and understanding across diverse backgrounds. As author Anne Wilson Schaef beautifully articulates, “Laughter is the language of the soul. It knows no boundaries and unites us in our humanity.” 

Inner Healing and Renewal: 

   Laughter serves as a catalyst for inner healing and renewal, revitalizing the spirit and nourishing the soul. Through laughter, individuals can tap into their innate resilience and find solace amidst life’s challenges. Spiritual teacher Eckhart Tolle reflects on the transformative power of laughter, stating, “Laughter dissolves the ego and brings us back to our true essence – a state of pure presence and joy.” 

A Personal Story

About 6 weeks ago I was introduced to a new Reality TV series called Relative Race on BYU-TV Now, I have not watched TV for 34 years, so this was a big stretch for me to take some time for a TV show. However, I downloaded the app and began to watch the series, episode after episode. Here’s what amazed me – I quickly noticed that my HRV (Heart Rate Variability) was increasing during my sleep. Why is this significant? HRV measures your Sympathetic (SNS or survival) nervous system (think of being scared) and Parasympathetic (Pretty Safe) nervous system. The calmer and more relaxed you are (Pretty safe) the higher your HRV. This TV show has me laughing my head off in the 1st half of the show, then shedding tears during the 2nd half. It stimulates those fun happy neurotransmitters and I get totally relaxed before bed. This little experiment has impacted my physiology and my psychology!  

An exercise to try

Years ago, in a personal growth workshop, the instructor asked us to laugh. Ah, have you ever just tried to laugh on the spot? Well, she demonstrated. She just began to laugh as loud as she could. It didn’t take long for all of us to be busting up laughing. Yes, you may have to manufacture the laughter to start, but once you do, I promise you will not be able to stop. Additionally, the laughter you generate from everyone else in the group will bring a huge smile to your heart! Try it and report back on how the laughter has impacted you!  


In essence, laughter emerges as a potent elixir for vitality, nurturing holistic well-being in body, mind, and spirit. From its profound physiological effects on organ systems to its transformative impact on psychological and spiritual dimensions, laughter transcends mere amusement to become a catalyst for healing and growth. As we embrace the gift of laughter in our lives, may we cultivate a deeper appreciation for its profound capacity to uplift, inspire, and nourish our entire being. 

So, this week, do something to make yourself, and perhaps everyone around you, laugh!!
