From grandmothers’ wisdom to popular culture, the age-old adage “laughter is the best medicine” has echoed through generations. We’ve all experienced the uplifting power of a hearty laugh — the way it can brighten our mood, ease tension and even seem to make pain more bearable. As it turns out, modern research is beginning to catch up with what many have intuitively known for centuries. From reducing stress hormones to improving mental health, laughter is proving to be a powerful tool in our wellness arsenal. Let’s explore how the simple act of laughing can profoundly affect our whole person — body, mind and spirit.
Recent research confirms that laughter has a profound effect on our well-being. A 2023 systematic review and meta-analysis of interventional studies found that laughter interventions significantly reduced cortisol levels, an essential stress hormone, by 31.9% compared to control groups (Kramer & Leitao, 2023). This reduction was even more pronounced when measured through salivary cortisol, showing a 43.9% decrease (Kramer & Leitao, 2023). The study included 315 participants across eight different trials, providing robust evidence for laughter’s stress-reducing effects.
The benefits of laughter extend beyond stress reduction. Studies have shown that laughter can improve several different aspects of health and well-being. A 2022 systematic review found that laughter enhanced mental health and reduced somatic symptoms — physical symptoms that a person notices before the onset of anxiety or emotional distress (Villines, 2022). This suggests that the joy of laughter can have a tangible impact on both our mental and physical well-being.
Interestingly, even a single laughter activity can have significant effects. The meta-analysis by Kramer and Leitao (2023) found that just a single laughter session induced a 36.7% reduction in cortisol levels compared to control groups. This implies that we don’t need to wait for long-term interventions to experience the benefits of laughter — its effects can be immediate and powerful.
The benefits of laughter extend to various clinical settings as well. A 2019 randomized controlled trial of 56 people with cancer found that laughter therapy could improve quality of life, with the 26 participants who engaged in laughter therapy showing better cognitive function and lower pain intensity compared to the 30 individuals in the control group (Villines, 2022). For those dealing with chronic conditions, a good laugh could be a valuable addition to their treatment plan.
In the Bible, the book of Proverbs offers timeless wisdom on the power of a joyful heart. Proverbs 17:22 tells us, “A merry heart does good like medicine, but a broken spirit dries the bones.” This ancient insight into the healing power of a joyful spirit aligns remarkably well with modern scientific research on the whole-person health benefits of laughter and positive emotions.
Remember, while laughter can be a powerful complement to a healthy lifestyle, it’s not a substitute for professional medical care. As Villines (2022) notes, there is no evidence that laughter can cure any medical condition, but it may improve a person’s subjective sense of well-being or quality of life. Always consult with your healthcare provider for any health concerns or before making significant changes to your health regimen.
