Background and Purpose
Depression is a widespread mental health disorder that differs significantly from normal mood changes and affects various aspects of life, including relationships and social interactions. Globally, approximately 4% of the population experiences depression, with higher prevalence in women (6%) compared to men (4%), and among those over 60 years old (5.7%) (Woodi et al. 2017). Depression is more common in women, with about a 50% higher prevalence, and is a major contributor to suicide, causing over 700,000 deaths annually worldwide, making it the fourth leading cause of death. In Iran, depression rates range between 5.7% and 7.3% across different populations (Montazeri et al., 2013). The disorder manifests differently in men and women, with symptoms like loss of interest, excessive crying, indecisiveness, and low energy being common. Women are more prone to depression due to factors like violence, economic hardship, workplace challenges, and sexual abuse. Additionally, people with mental health disorders, including depression, face significant challenges, such as reduced life expectancy—living 10 to 20 years less than the general population—underscoring the need for targeted interventions (Metrics, & Evaluation, 2021).
Research indicates that both laughter and physical activity have significant benefits for physical and mental health. Laughter, particularly through practices like laughter yoga—which combines yoga stretches and breathing exercises with laughter—has been shown to positively impact various bodily systems. It promotes muscle relaxation, boosts immune response, balances hormones, and enhances mental well-being. Laughter yoga also improves physiological functions such as respiration, digestion, and blood pressure, while reducing stress hormones and stimulating endorphin release, leading to a greater sense of well-being.
Similarly, physical activity is recommended as a low-cost, low-risk strategy for preventing and treating depression, which often results in economic burdens and deteriorating physical health. Regular exercise helps manage weight, improve cardiovascular health, and reduce the risk of chronic diseases like diabetes and hypertension. Importantly, physical activity, and laughter yoga in particular, are effective ways to improve mental health, offering a natural and accessible means to enhance overall well-being.
Research indicates that laughter can boost catecholamine levels and improve cognitive function. While laughter does not reverse aging, it helps maintain alertness and memory, especially in older adults. In stressful situations, laughter reduces stress hormones in the blood, promoting relaxation and health. Recent studies have shown that laughter yoga can significantly enhance mental and physical health, particularly by increasing life expectancy. Given the lack of sufficient research in Iran on the effects of laughter yoga on depression symptoms and life expectancy in women, this study aims to explore this important issue further.
Material and Methods
This study utilized a quasi-experimental design with a pre-test and post-test control group to investigate the effects of laughter yoga on depression and hope levels among women. The research sample consisted of women attending classes at Red Crescent centers in Isfahan. A multistage random sampling method was used to select one center and a specific class within that center. From this class, 30 women who scored highest on the Beck Depression Inventory-II (BDI-II) and lowest on the Adult Hope Scale (AHS) were chosen and randomly assigned to either the experimental group (15 participants) or the control group (15 participants).
The BDI-II, a widely used self-report instrument, assessed depression levels, while the AHS measured participants' levels of hope based on Snyder’s cognitive model, focusing on agency (motivation) and pathways (planning to achieve goals). Both instruments have demonstrated strong reliability in previous studies.
The intervention involved 24 laughter yoga sessions over eight weeks, with three sessions per week, each lasting 45 minutes. The experimental group participated in these sessions, which included clapping with rhythmic chants, stretching exercises, and playful activities designed to induce laughter. Each session concluded with positive affirmations and meditation to enhance participants' mood and overall sense of well-being. The control group did not engage in any physical activities during this period.
Results
Results showed that the post-test scores for hope in life were significantly different between the experimental and control groups after controlling for pre-test scores (P= 0.001). The laughter yoga training effectively increased the level of hope in life among women in the post-test phase. The impact of this training on improving hope in life was quantified at 0.546, indicating that approximately 54.6% of the variance in hope in life can be attributed to group membership or the effect of the training.
Conclusion
This study demonstrates that an eight-week laughter yoga program can significantly reduce symptoms of mild to moderate depression in women. The findings revealed a significant difference between pre-test and post-test depression scores (P=0.002), aligning with previous research that supports laughter yoga as an effective complementary therapy for depression. Studies such as those by Keykha-Hosseinpour (2013) and Eshgh et al. (2011) have similarly shown that physical activity plays a crucial role in improving mental health disorders. Moreover, laughter yoga has been linked to increased levels of mood-enhancing hormones like endorphins and serotonin, which help alleviate depression symptoms.
In addition to mood improvement, laughter yoga can reduce stress hormone levels, particularly cortisol, leading to better sleep quality and decreased anxiety symptoms. Research also suggests that enhancing the immune system through practices like laughter yoga can reduce the risk of depression, as a weakened immune system is often associated with mental health issues. Studies, including those by Tellhed et al. (2019) and Liu et al. (2022), confirm that yoga and related techniques effectively lower stress and anxiety, improving overall quality of life, especially in individuals with chronic conditions.
The study also found that laughter yoga significantly increased hope scores in the experimental group (P=0.001), indicating its positive impact on life satisfaction and mental well-being. Physical activities and exercise have similarly been shown to enhance life expectancy and mental health by fostering social connections and a sense of belonging, which contribute to increased hope. Laughter yoga's stress-reducing and relaxation-inducing effects further enhance hope and life satisfaction.
Physiologically, laughter affects various bodily systems, including the nervous, muscular, respiratory, circulatory, endocrine, and immune systems. It reduces stress hormones like cortisol while increasing happiness-related hormones such as endorphins and serotonin, thus improving mood and reducing depression. Psychologically, laughter directly combats depression by reducing stress, anxiety, and tension while enhancing mood, self-esteem, energy, and vitality. These combined benefits suggest that laughter yoga is a safe, effective, and accessible intervention for improving mental health and quality of life, particularly in women.
Given its efficacy, laughter yoga is recommended as a complementary therapeutic tool in mental health programs, particularly for women. Future research should explore its effects on other populations, such as men, adolescents, students, and patients, using longer intervention periods and multiple control groups to provide more robust evidence. Overall, laughter yoga presents a cost-effective, non-pharmacological approach to enhancing mental health and could be widely promoted to improve public awareness of mental wellness strategies. The study suggests that laughter yoga not only serves as an effective intervention for reducing depression and enhancing hope but also as a comprehensive tool for improving overall mental and social well-being in various communities. Further research will help better understand its mechanisms and optimize its use.
