A systematic review of the effect of laughter yoga on physical function and psychosocial outcomes in older adults

The effect of laughter yoga on well-being, perceived stress, and academic self-efficacy in nursing students: A randomized controlled trial

Despite rigorous theoretical and clinical training, nursing students face emotional and academic challenges that can harm their well-being. Nonetheless, there is a dearth of research investigating the impact of laughter yoga (LY) on nursing students' well-being, perceived stress, and self-efficacy. The aim of this single-blinded, two-armed randomized controlled trial is to evaluate the effect of LY on nursing students' well-being, perceived stress, and academic self-efficacy (ASE). A total of five sessions of LY were applied to the intervention group. The analysis included a total of 83 nursing students (intervention group n = 41 and control group n = 42). Repeated-measures multivariate analysis of variance (MANOVA) and paired-samples t-test were used for data analysis. Results revealed that the intervention group showed a significant increase in well-being (p < .001) and a decrease in perceived stress after LY (p < .01). However, statistically significant differences between the intervention and control groups were not found in well-being, perceived stress, and ASE (p > .05). These results indicate the potential effects of LY on the students' well-being and perceived stress. Community mental health nurses and educators can use LY to improve well-being in universities.

The effect of laughter yoga and music intervention on depression, anxiety, and stress in the Rafsanjan-Iran aged: a randomized clinical trial study

OBJECTIVES

This study aimed to compare the effects of laughter yoga and music intervention on depression, anxiety, and stress in aged individuals referred to Rafsanjan health centers.

METHOD

In this 3-arm randomized clinical trial, 91 depressed aged participants aged 60-75 years, referred to Rafsanjan health centers, were randomly assigned to intervention and control groups. The study followed a parallel group design with an allocation ratio of 1:1. The laughter yoga intervention was conducted twice a week for eight weeks, and music intervention consisted of 30-min sessions twice a week for eight weeks. The control group received no intervention ('No treatment' concurrent control). Assessments for depressive symptoms (primary outcome), anxiety, and stress were conducted at baseline, post-intervention, and one month after the intervention.

RESULTS

A total of 84 patients were analyzed in three groups included the laughter yoga intervention (n = 31), music intervention (n = 25), or control group (n = 28). Repeated measures ANOVA revealed a significant decrease in depressive and anxiety symptoms (p < 0.001) from pre-test to post-test and one-month follow-ups. The greatest impact of the intervention programs on stress was observed immediately after the intervention, but stress increased one month after the intervention programs (p = 0.125).

CONCLUSION

Both laughter yoga and music interventions proved effective in improving depression, anxiety, and stress in aged individuals. However, laughter yoga intervention demonstrated a superior effect and better acceptance among elders.

A Pilot Study Investigating the Feasibility, Reach-Out, Acceptability, Fidelity, and Efficacy of a Group Laughie Prescription on the Well-Being of Earthquake Survivors in Türkiye

Mental health and quality of life may be negatively impacted among earthquake survivors. This pilot study evaluates the use of and reports on the preliminary effects of participating in a 1-minute Laughie (Laugh Intentionally Everyday) Laughter Prescription on well-being in earthquake survivors in Türkiye. A Group Laughie intervention was delivered using a within-subject (n = 20; M age = 34.78 ± 6.65; 14 female) pretest-posttest design. Group Laughies were delivered once a day over 2 weeks with participants prescribed to further laugh with the Group Laughie recording twice a day, resulting in 3 minutes of intentional laughter daily. Data were collected using a range of questionnaires to track feasibility, reach-out, acceptability, fidelity, and efficacy, including Laughie Checklists, a Post-Intervention Perceived Impact Measure (PIPIM) in the form of the Positive Psychology One-off Post-intervention measure (PPOP), and the World Health Organization (WHO-5) well-being index. Results indicated high intervention fidelity using Laughie Checklists and positive post-intervention perceived impact using the 11-point Likert-scaled PPOP (x = 7.62 ± 1.44). After the intervention, a statistically significant difference (p < 0.001) was found between WHO-5 well-being index pretest scores (x = 2.16 ± 1.00) and post-test (x = 4.08 ± 0.24). This study demonstrated beneficial effects of the Laughie prescription on earthquake survivors. This is the first intervention to explore an online Group Laughie intervention. Health professionals and especially nurses can use the 1-minute Laughie prescription in the form of a Group Laughie intervention to increase the well-being of individuals and improve perceived mental health.

The Effects of Laughter Therapy on Perceived Stress and Quality of Life in Women With Breast Cancer Receiving Chemotherapy: A Parallel-Group Randomized Controlled Pilot Trial

BACKGROUND

Women with breast cancer experience various symptoms secondary to chemotherapy that reduce their quality of life and increase their stress levels.

OBJECTIVE

To evaluate the effects of laughter therapy on perceived stress levels and quality of life in women with breast cancer receiving chemotherapy using a parallel-group randomized controlled pilot trial.

METHODS

Forty-two women were randomly assigned to intervention and control groups. The intervention group received 40 minutes of laughter therapy twice a week for 8 weeks. The control group received routine treatment. The women in both groups completed the Perceived Stress Scale and SF-12 Health Survey at baseline, week 5, and week 9 after randomization.

RESULTS

There was a significant decrease in the mean Perceived Stress Scale scores in the intervention group compared with those in the control group at weeks 5 and 9 compared with baseline, and the difference between groups by measurement week was significant (P < .001). Women in the intervention group had higher Physical Component Summary-12 and Mental Component Summary-12 scores in weeks 5 and 9 compared with those in the control group, and there was a significant difference between groups in terms of change in the Physical Component Summary-12 and Mental Component Summary-12 mean scores over time (P < .001).

CONCLUSION

Laughter therapy is possible to use as a nursing intervention to reduce the perceived stress levels and increase the quality of life of women receiving chemotherapy for breast cancer.

IMPLICATIONS FOR PRACTICE

Nurses can apply laughter therapy in the symptom management of women receiving chemotherapy.

Effects of Laughter Therapy on Improving Negative Emotions Associated with Cancer: A Systematic Review and Meta-Analysis

INTRODUCTION

With aging and growth of the population, the risk of cancer incidence and mortality is rapidly increasing. However, psychosocial treatment has been seriously neglected in many healthcare settings. Laughter therapy is a therapeutic program to improve emotional wellbeing and health which has been applied as a complementary treatment. We aim to explore effects of laughter therapy for patients with cancer on their negative emotions such as depression, anxiety, stress, pain, and fatigue.

METHODS

We searched the Cochrane Library, Embase, PubMed, Scopus, Web of Science, WANFANG data, Weipu (VIP), Chinese National Knowledge Infrastructure (CNKI) and independently rated the risk of bias in every article using the Cochrane Collaboration's Risk of Bias Assessment Tool. Review Manager and STATA software were used to pool the individually included studies.

RESULTS

Seven studies were found eligible to be included in the present review. Overall, study quality was relatively high. Our findings suggest that laughter therapy might have a positive effect on improving emotional response in cancer patients. Arguably, laughter therapy, whether humor or laughter, has a positive effect on anxiety, stress, pain feeling, fatigue, and depression in cancer patients.

CONCLUSIONS

Laughter therapy is a convenient, multi-modality, flexible-duration therapy to improve negative emotions in cancer patients, regardless of their gender, age, and type of cancer.

Effects of laughter yoga on health-related quality of life in cancer patients undergoing chemotherapy: a randomized clinical trial

BACKGROUND

Chemotherapy is associated with a wide range of physical and psychological side effects, so complementary and alternative therapies may be practiced as an independent treatment or combined with the standard ones to improve health-related quality of life of cancer patients. Laughter yoga has predominantly been used as a complementary therapy to enhance health and wellbeing of ordinary people and patients with chronic diseases. However, to date, few studies have evaluated the effects of this modern exercise on cancer patients undergoing chemotherapy in clinical settings, to the best of the authors' knowledge. the present study aimed to investigate the effects of Laughter Yoga on the health-related quality of life of cancer patients undergoing chemotherapy.

METHODS

This study was a two-group randomized clinical trial on 69 cancer patients undergoing chemotherapy at Reza Radiotherapy and Oncology Center, Iran in 2018. Patients were randomly divided into intervention and control groups. The intervention group received laughter yoga for four sessions at one-week intervals. Each session consists of one part and lasts for 20-30 min. Patients' health-related quality of life was assessed before and after the laughter yoga sessions using Quality of Life Questionnaire European Organization for Research and Treatment of Cancer (EORTC QLQ-C30) version 3.0. SPSS Statistics (v.20 software was used to conduct Chi-square, independent t-test, Mann-Whitney, Wilcoxon and paired t-tests analyses of the data.

RESULTS

The number of participants in intervention and control groups were 34 and 35, there was no significant difference of demographic and disease related characteristics and pre-intervention HRQOL between two groups. In the intervention group, there is significant difference between pre- and post-intervention scores (Mean ± Standard Deviation) of emotional functioning (12.99 ± 10.49), physical functioning (0.78 ± 6.08), role functioning (3.43 ± 7.97), fatigue (-8.82 ± 22.01), pain (-8.33 ± 11.78), sleep disturbance (-15.68 ± 18.77), and global health and quality of life (6.37 ± 5.04) (p < 0.05). There was no significant change in the control group. Participants reported no adverse events.

CONCLUSIONS

A structured laughter yoga intervention in a hospital setting effectively improved health-related quality of life for cancer patients undergoing chemotherapy. Benefits to many patients could be expected if this would become a part of routine care.

Laughter as medicine: A systematic review and meta-analysis of interventional studies evaluating the impact of spontaneous laughter on cortisol levels

OBJECTIVES

Laughter as an expression of humor has been recognized as good medicine for centuries. The health benefits of humor-induced well-being remain unclear and thus we conducted a systematic review and meta-analysis of interventional studies to evaluate the impact of spontaneous laughter on stress response as measured by cortisol levels.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

MEDLINE/PubMed, EMBASE, PsycINFO, Scopus, and Clinicaltrials.gov.

ELIGIBILITY CRITERIA

Interventional studies, which could be either randomized placebo-controlled trials (RCTs) or quasi-experimental studies, conducted in adults that compared any spontaneous laughter intervention to a controlled setting and reported changes in cortisol levels were selected.

DATA EXTRACTION AND SYNTHESIS

We examined the impact of laughter on percentage change in cortisol levels by calculating pooled estimates of the absolute differences between arithmetic means before and after interventions as compared to control using random-effects model.

RESULTS

Eight studies (315 participants; mean age 38.6) met our inclusion criteria; four were RCTs and four were quasi-experiment studies. Five studies evaluated the impact of watching a humor/comedy video, two studies evaluating laughter sessions administered by a trained laughter therapist, and one study evaluating a self-administered laughter program. Pooling these data showed a significant reduction in cortisol levels by 31.9% (95%CI -47.7% to -16.3%) induced by laughter intervention compared to control group with no evidence of publication bias (P = 0.66). Sensitivity analyses demonstrated that even a single laughter session induced a significant reduction of 36.7% in cortisol (95%CI -52.5% to -20.8%). In addition, analyses including the four RCTs reinforced these results by demonstrating a significant reduction in cortisol levels promoted by laughter as compared to the placebo arm [-37.2% (95%CI -56.3% to -18.1%)].

CONCLUSIONS

Current evidence demonstrates that spontaneous laughter is associated with greater reduction in cortisol levels as compared with usual activities, suggesting laughter as a potential adjunctive medical therapy to improve well-being.

Perceived benefit of yoga among adults who have practiced yoga for a long time: a qualitative study

BACKGROUND

Previous quantitative studies have shown many of the perceived benefits of yoga practice on the mind and body. Although there are many quantitative studies in the international literature on yoga, the number of qualitative studies showing the experience of yoga practice is insufficient. An accurate demonstration of yoga participents experiences, opinions, and judgments on this subject requires a qualitative, rather than a quantitative approach.

PURPOSE

This study was to explore the benefit perceived by adults who have practiced yoga for a long time.

DESIGN AND METHOD

This qualitative study is based on a hermeneutic-phenomenological approach. The research sample consisted of 18 adults who volunteered to participate in the research and regularly joined yoga practice. The study data were collected through individual and focus group interviews with the participants who practise yoga and analyzed by content analysis method.

RESULTS

We created five themes. Themes coded by researchers: meaning of the concept of yoga (theme 1), physical, mental, and social state before starting yoga (theme 2), reasons for practising yoga (theme 3), the participants' experiences related to their physical and mental health and social relationships (theme 4), and difficulties of doing yoga (theme 5). In addition, individuals in the study reported their perceptions of the concept of "yoga" through the creation of metaphors that completed the following sentence "yoga is like ……". These metaphors were used to give insight into the participants deep feelings about yoga.

CONCLUSIONS

Both in their individual and focus group interviews, almost all of the participants described that doing yoga has positive benefits on the mind and body. The positive experiences of the participants in the study included decrease in pain and flexibility, increase in sleep quality, development of positive personality traits, increase in self-esteem, and coping with anxiety and stress more effectively. Because the study was qualitative and long-term, it was able to evaluate the beliefs, attitudes and behaviors of individuals in a realistic, systematic, and detailed manner.

Effects of a 'social activity program that encourages interaction' on rural older people's psychosocial health: Mixed-methods research

BACKGROUND

We developed a program that encourages interaction among older people living at home by combining face-to-face and online activities and examined its effects on older adults' psychosocial health.

METHODS

In this mixed-methods study, we recruited 11 women and 6 men (Mage = 79.5 ± 6.4 years), who lived in a rural community and participated in a senior citizen club. The intervention was conducted for 13 months, comprising monthly face-to-face group and social media activities. For the program process evaluation, we collected focus-group interview data on participants' perceptions of their personal lives, club membership, and community post-intervention. For the outcome evaluation, we collected six outcome measures pre- and post-intervention: loneliness, subjective health, subjective well-being, self-esteem, social support and social activity satisfaction. Finally, through the integration of the process-outcome evaluation, we inferred what effects the program had on participants' psychosocial health.

RESULTS

In the process evaluation, we identified four themes: 'Stimulation brought about by relationships with peers,' 'Realization as to where they feel they belong,' 'Rethinking of oneself in the community,' and 'Awareness of attachment to and coexistence with the community.' In the outcome evaluation, the outcome measures were maintained without significant decline post-intervention.

CONCLUSION

Through the integration of the process-outcome evaluation, we deduced three effects of the program on psychosocial health: (1) fulfilment of subjective health, (2) maintenance and assurance of moderate distance connectedness and (3) orientation toward aging in place.

IMPLICATIONS FOR PRACTICE

This study offers a promising opportunity for further development and research into community-based preventive nursing care intervention strategies to maintain the psychosocial health of homebound older people in communities with social activity groups.

Laughter yoga as an enjoyable therapeutic approach for glycemic control in individuals with type 2 diabetes: A randomized controlled trial

BACKGROUND

Laughter has been reported to have various health benefits. However, data on the long-term effects of laughter interventions on diabetes are limited. This study aimed to investigate whether laughter yoga can improve glycemic control among individuals with type 2 diabetes.

METHODS

In a single-center, randomized controlled trial, 42 participants with type 2 diabetes were randomly assigned to either the intervention or the control group. The intervention consisted of a 12-week laughter yoga program. Hemoglobin A1c (HbA1c), body weight, waist circumference, psychological factors, and sleep duration were evaluated at baseline and week 12.

RESULTS

Intention-to-treat analysis showed that participants in the laughter yoga group experienced significant improvements in HbA1c levels (between-group difference: -0.31%; 95% CI -0.54, -0.09) and positive affect scores (between-group difference: 0.62 points; 95% CI 0.003, 1.23). Sleep duration tended to increase in the laughter yoga group with a between-group difference of 0.4 hours (95% CI -0.05, 0.86; P = 0.080). The mean attendance rate for laughter yoga program was high (92.9%).

CONCLUSIONS

A 12-week laughter yoga program is feasible for individuals with type 2 diabetes and improves glycemic control. These findings suggest that having fun could be a self-care intervention. Further studies with larger numbers of participants are warranted to better evaluate the effects of laughter yoga.

Effects of Exercise on Sleep in Older Adults: An Overview of Systematic Reviews and Meta-Analyses

We aimed to systematically analyze reviews of randomized clinical trials that investigate the overall effect of exercise and of different types of exercise on sleep in older adults. Meta-analysis was performed to obtain the standardized mean difference of the effect of the different types of exercise. Twenty systematic reviews published between 2012 and 2020 met the inclusion criteria of this overview. Moderate significant effects of exercise were observed on overall sleep quality and its subjective components (quality, duration, latency, habitual efficiency, medication use, and daytime dysfunction). Among the types of exercise, sensitivity analysis revealed significant effects of Pilates, Tai Chi, and Baduanjin Qigong on sleep quality. Exercise has a positive effect on sleep quality in older people. Our findings are extremely important, especially for decision makers in the health area, permitting the planning of actions and evidence-based decision making.

Salutogenic Model-Based Frailty Prevention Program for Pre-Frail Women Aged 55 Years and Over (SAFRAPP): A Study Protocol for a Randomized Controlled Trial

Background: Frailty is a geriatric syndrome which is more higher among women. Limited evidence suggests a model-based intervention for preventing worsening frailty for women. Purpose: This protocol describes a single-blinded, two-armed randomized controlled study purposing to examine the effectiveness of Salutogenic Model-Based Frailty Prevention Program (SAFRAPP) for pre-frail women. Methods: Eighty-four eligible participants from vocational institutions of a municipality in Turkey is randomly allocated to either the SAFRAPP intervention or the control group. The SAFRAPP is a 6-week online nurse-led intervention program comprising of laughter yoga, health education and case management. The intervention is rooted in the Salutogenic Model, which focuses on strengthening individuals' coping capacity to deal with stressors. The primary outcomes are the frailty and sence of coherence scores and the secondary outcomes are the well-being, quality of life and fear of fall scores, and number of falls and emergency admissions in the past three months. The study data for intervention and control group is obtained at four times: At baseline and at the 3-month, 6-month and 9-month follow-ups. Results: The protocol was registered at ClinicalTrials.gov (identifier number NCT04787432, registration date: 08/03/2021). Eligibility, baseline measurements, randomization, and intervention are completed. The follow-ups are ongoing. Implications for Practice: There is unsufficient evidence regarding the effectiveness of a model-based health promotion interventions for prevention of frailty. The SAFRAPP will provide evidence on prevention of frailty and improving sense of coherence of pre-frail women.

Meta-Analysis of the Effect of Yoga Practice on Physical Fitness in the Elderly

The purpose of this study was to meta-analyze the effects of yoga intervention on physical fitness in the elderly. The following databases were systematically searched in 25 March 2021: Cochrane, PubMed and Embase. A total of 656 papers was identified through key word combinations, finally, 12 studies were included in the meta-analysis. The main conclusions are as follows. First, yoga practice showed moderately positive effects on muscle strength, balance, mobility, and lower body flexibility, but had no significant effect on cardiorespiratory endurance and upper body flexibility. Second, sub-group analysis showed that subjects in their 60s and 70s and yoga practice for 9–12 weeks had a large positive effect on physical fitness. Yoga is a multimodal activity that improves muscle strength, balance, and flexibility in the elderly, and physical activity policies should continue to promote yoga as an activity that enhances physical and mental wellbeing in this population.
