Assessment of Medical Clowning in Influencing the Anxiety and Behavior Scores of Children Undergoing Various Dental Treatments and the Stress Levels of the Operator.

Aim: To investigate the potential effectiveness of "medical clowns" on preoperative, intraoperative, and postoperative anxiety of children undergoing various dental treatments and also its effect on the operator's stress levels in a dental setup. Materials and methods: A total of 170 pediatric patients, aged 4-8 years, indicated for preventive therapy, extractions, restorative, and endodontics were included and divided into two groups [group I-audiovisual (A-V) aids; group II-medical clowns], group of 85 patients each after recording Modified yale preoperative scale. Both pre- and postoperatively, Frankl's behavior score was recorded for each patient. During treatment, the face, legs, activity, cry, consolability (FLACC) pain scale, and dental operator's stress level were recorded. Results: Intervention of medical clowns positively influenced children during dental treatment by increasing their pain threshold. The majority of children showed positive Frankl rating scales after dental treatment. Also, the operator's stress was significantly reduced, which led to enhanced treatment outcomes. Conclusion: Humor yields the power of healing, distracts pediatric patients, reduces their anxiety, and alleviates their pain, conferring the patients with a sense of laughter, creativity, and care.Therefore, medical clowns in pediatric dentistry can prove to be serviceable and valuable as a nonpharmacological approach to behavior management.

Impact of Laughter Yoga on Test Anxiety and Education Stress of 8th Grade Students: An Experimental Study.

Objective: In an exam-based education system, it is of utmost importance to identify levels of test anxiety and educational stress that directly affect success, and to reduce anxiety. A study was conducted to examine the effects of laughter yoga on test anxiety and educational stress in 8th grade students in Turkey. Methods: A cluster sampling, parallel-group randomized controlled trial with pre-test/post-test design studied 64 students (32 in the intervention group and 32 in the control group). The intervention group received laughter yoga sessions twice a week for 6 weeks. The control group received no intervention. Data were collected by a demographic questionnaire, the Westside Test Anxiety Scale, and the Educational Stress Scale. Results: After laughter yoga, the intervention group showed a significant decrease in test anxiety (d = 0.859; p < 0.005) and educational stress scores (d = 0.52875; p < 0.001) compared to the control group. Conclusion: Laughter yoga was associated with decreased test anxiety and educational stress. Laughter yoga activities in schools are recommended to decrease educational stress and test anxiety of students.

Evolution of laughter from play.

In this hypothesis, I discuss how laughter from physical play could have evolved to being induced via visual or even verbal stimuli, and serves as a signal to highlight incongruity that could potentially pose a threat to survival. I suggest how laughter's induction could have negated the need for physical contact in play, evolving from its use in tickling, to tickle-misses, and to taunting, and I discuss how the application of deep learning neural networks trained on images of spectra of a variety of laughter types from a variety of individuals or even species, could be used to determine such evolutionary pathways via the use of latent space exploration.

The Effects of Laughter Yoga on Happiness and Stress in Nursing Students Going into Clinical Practice for the First Time.

Background: There are numerous difficulties that nursing students must overcome in the nursing practice environment. This circumstance mainly impacts the happiness and stress levels of nursing students who lack clinical practice. Aim: In this study aimed to examine the effect of laughter yoga (LY) on nursing students' happiness and stress levels attending to clinical practice for the first-time. Method: In this randomized controlled trial, a totally 50 nursing students were included from a nursing school in Turkey. Data were collected between December 2022-January 2023 via The Happiness Scale and the Perceived Stress Scale for Nursing Students. A total of eight LY lessons for 4 weeks were practiced to the laughter group (LG). Result: The Happiness Scale's means were compared between the groups before and after the intervention, and the results revealed a significant increase (p < 0.05). There was not a significant difference in the stress scale scores between both the groups following LG and clinical practice (t: -1.780; p = 0.081). However, the stress scores of the LG decreased significantly after the LY sessions were completed (b: 3.595; p = 0.001). Conclusion: LY can be an effective method to be used to help increase happiness and reduce the stress of nursing students for first-time entering clinical practice.

Development of a novel tool to investigate human laughter behaviour and experience.

We present a questionnaire exploring everyday laughter experience. We developed a 30-item questionnaire in English and collected data on an English-speaking sample (N = 823). Based on Principal Component Analysis (PCA), we identified four dimensions which accounted for variations in people's experiences of laughter: laughter frequency ('Frequency'), social usage of laughter ('Usage'), understanding of other people's laughter ('Understanding'), and feelings towards laughter ('Liking'). Reliability and validity of the LPPQ were assessed. To explore potential similarities and differences based on culture and language, we collected data with Mandarin Chinese-speaking population (N = 574). A PCA suggested the extraction of the same four dimensions, with some item differences between English and Chinese versions. The Laughter Production and Perception Questionnaire (LPPQ) will advance research into the experience of human laughter, which has a potentially crucial role in everyday life.

A structured laughter yoga therapy program on patients with chemotherapy-induced nausea and vomiting: A randomized clinical trial.

Objetive: Chemotherapy is a prevalent cancer treatment, often accompanied by debilitating side effects such as nausea and vomiting. This study explores the potential effectiveness of laughter yoga, a combination of exercise and voluntary laughter, in alleviating chemotherapy-induced nausea and vomiting. Methods: This two-group randomized clinical trial was conducted on 69 cancer patients undergoing chemotherapy at the Reza Chemotherapy and Oncology Center, Mashhad, Iran, in 2018. Patients were randomly divided into intervention and control groups. Both groups received routine self-care training, with the addition of four 20-min to 30-min laughter yoga sessions held immediately before one of their chemotherapy appointments for the intervention group only. Nausea and vomiting were assessed using the Morrow Assessment of Nausea and Emesis questionnaire at two stages, before and after the intervention. Data were analyzed with Chi-square, Independent-t, Mann-Whitney, Wilcoxon, and McNemar tests using Statistical Package for the Social Sciences (SPSS). Results: The mean age of patients in the intervention group was 49.0 ± 9.6 years, while in the control group, it was 45.2 ± 12.6 years. The intragroup comparison showed a statistically significant decrease in the severity and duration of nausea in the intervention group and a statistically significant increase in the severity and duration of nausea in the control group from pre-test to post-test (P < 0.05). The intergroup comparison showed no statistically significant difference between the two groups in terms of vomiting conditions. Conclusions: Laughter yoga demonstrates promise in improving chemotherapy-induced nausea, suggesting its potential recommendation for managing this distressing side effect. Further research is warranted to explore its broader application in cancer care. Trial registration: This study (No. IRCT20180429039463N1) was registered in the Iranian Registry of Clinical Trials on 21/08/2018.

Association between laughter, frailty, and depression in rheumatoid arthritis patients.

OBJECTIVE: This study aimed to determine whether there are associations between laughter, disease activity, frailty, and depression in rheumatoid arthritis (RA) patients. METHODS: A total of 240 patients were included in this prospective cohort study on frailty in RA patients between March 2021 and June 2022. Patients were divided into the following four groups according to the frequency of laughter: "almost every day," "1-5 days per week," "1-3 days per month," and "never or almost never." Patient characteristics were compared among the four groups by analysis of variance. Factors associated with laughter were identified by multivariable logistic analysis. RESULTS: The mean 28-joint Disease Activity Score using CRP was 1.91, with 70.7% of patients in remission and 12.6% in low disease activity. For the "almost every day" (42.5% of patients), "1-5 days per week" (40.0%), "1-3 days per month" (11.3%), and "never or almost never" (6.3%) groups, scores of the Kihon Checklist (KCL) for assessing frailty status were 3.5, 4.6, 7.3, and 8.1 (p < .001), respectively, and scores of the Beck Depression Inventory (BDI-II) were 8.4, 10.7, 15.1, and 16.5 (p < .001), respectively. Multivariable analysis revealed that KCL (OR: 0.81, 95% CI: 0.73-0.90) and BDI-II (OR: 0.91, 95% CI: 0.86-0.95) scores were independently associated with the frequency of laughter. CONCLUSION: Frailty and depression were associated with laughter in RA patients with controlled disease activity. Interventions aimed at not only disease activity control but also frailty prevention may lead to a life filled with laughter.

Mini-review: Wild laughs: Ontogenesis and phylogenesis of humour.

This mini-review discusses the existing evidence on various forms of humour and humour-like behaviour in non-human animals, combining ontogenetic and phylogenetic perspectives. The first section describes humour-like behaviours, from the simplest to the most complex form (from laughing, tickling, joking, and chasing to ToM humour). In the second section, we propose the SPeCies (Social, Physiological, and Cognitive) Perspective, which frames the various types of humour based on Social motivation, Physiological state, and Cognitive skills. Finally, in the third section, we discuss future directions for further development.

'Should we laugh?' Acoustic features of (in)voluntary laughters in spontaneous conversations.

Laughter is one of the most common non-verbal features; however, contrary to the previous assumptions, it may also act as signals of bonding, affection, emotional regulation agreement or empathy (Scott et al. Trends Cogn Sci 18:618-620, 2014). Although previous research agrees that laughter does not form a uniform group in many respects, different types of laughter have been defined differently by individual research. Due to the various definitions of laughter, as well as their different methodologies, the results of the previous examinations were often contradictory. The analysed laughs were often recorded in controlled, artificial situations; however, less is known about laughs from social conversations. Thus, the aim of the present study is to examine the acoustic realisation, as well as the automatic classification of laughter that appear in human interactions according to whether listeners consider them to be voluntary or involuntary. The study consists of three parts using a multi-method approach. Firstly, in the perception task, participants had to decide whether the given laughter seemed to be rather involuntary or voluntary. In the second part of the experiment, those sound samples of laughter were analysed that were considered to be voluntary or involuntary by at least 66.6% of listeners. In the third part, all the sound samples were grouped into the two categories by an automatic classifier. The results showed that listeners were able to distinguish laughter extracted from spontaneous conversation into two different types, as well as the distinction was possible on the basis of the automatic classification. In addition, there were significant differences in acoustic parameters between the two groups of laughter. The results of the research showed that, although the distinction between voluntary and involuntary laughter categories appears based on the analysis of everyday, spontaneous conversations in terms of the perception and acoustic features, there is often an overlap in the acoustic features of voluntary and involuntary laughter. The results will enrich our previous knowledge of laughter and help to describe and explore the diversity of non-verbal vocalisations.

Mind-Body Therapies in the Management of Otolaryngologic Disease: A State-of-the-Art Review of Randomized Controlled Trials.

OBJECTIVE: To review and assess the peer-reviewed literature on the utility of mind-body therapy (MBT) as an adjunct treatment in the management of otolaryngologic disease. DATA SOURCES: PubMed, Embase, and Cochrane. REVIEW METHODS: Randomized control trials (RCTs) of MBTs in the management of otolaryngologic disease from 2002 to 2022 were identified and included according to predefined criteria. Interventions requiring expensive equipment were excluded because the goal of MBT is to be cost-conscious. All studies were subjected to a two-stage blinded screening, extraction, and appraisal process. The outcomes of the intervention and control groups were compared. CONCLUSION: RCTs of MBTs, including breathing exercises (4), aromatherapy (2), biofeedback (2), meditation, (2), and yoga (2), have been studied in several otolaryngologic conditions, including septoplasty/rhinoplasty (3), head and neck cancer (2), facial palsy (2), and tinnitus (2). Most studies were of moderate risk of bias on appraisal, and each MBT studied was found to significantly reduce subjective and objective distress associated with the otolaryngologic condition in question. IMPLICATIONS FOR PRACTICE: Despite a paucity of strong evidence supporting the universal use of MBTs, our review suggests that MBTs are cost-effective and easily deployable complementary tools in the management of otolaryngologic disease. Future large, methodologically rigorous RCTs are needed to address the limitations of the included studies, such as improper blinding and inappropriate statistical analysis. As MBTs are studied further, a case for their current use can be made because of their low cost and minimal risk to patients.

The Effects of Laughter Yoga on Perceived Stress, Positive Psychological Capital, and Exercise Capacity in Lung Cancer Chemotherapy Patients: A Pilot Randomized Trial.

BACKGROUND: Lung cancer is the malignant tumor with the highest morbidity and mortality rate in China. Although chemotherapy is effective in improving clinical symptoms, it causes a variety of acute and chronic side effects, seriously aggravating the psychological stress of patients. Laughter Yoga as a new type of aerobic exercise can effectively reduce stress levels and increase positive mood in patients. This study aimed to examine the effects of laughter yoga on perceived stress, positive psychological capital, and exercise capacity in lung cancer patients. METHODS: This study was a randomized, single-blind, parallel-group trial. The study enrolled 84 lung cancer chemotherapy patients from a general hospital in central China. These patients were randomly allocated to control and intervention groups (n = 42 per group) after baseline assessments. Patients in the control group received routine care and those in the intervention group received laughter yoga intervention. Perceived stress, positive psychological capital, and exercise capacity were assessed at baseline, immediately post-intervention. RESULTS: During the implementation of the study, there were 2 dropouts in each of the intervention and control groups. Ultimately, 80 patients in the control and intervention groups completed the trial. Patients who received laughter yoga intervention had significantly higher scores in positive psychological capital (P < .01, Cohen's d = 0.692) and exercise capacity (P < .01, Cohen's d = 0.659). Discernible differences were also observed in perceived stress (P < .01, Cohen's d = 1.087) between the 2 groups. CONCLUSIONS: The results of this study suggest that laughter yoga is an effective way and may produce beneficial effects on perceived stress, positive psychological capital and exercise capacity.

[Beneficios de la terapia de la risa en los niveles de depresión en niños diagnosticados con cáncer: estudio de caso.] / Benefits of laughing therapy on depression levels in children diagnosed with cancer: a case study.

OBJECTIVE: Pediatric cancer emotionally affects infants causing depression which must be intervened in a timely manner as an essential part of the treatment. Therefore, the present study sought to identify the benefits of laughter therapy on the levels of depression in children diagnosed with cancer in a foundation in Cali, Colombia. METHODS: The sample consisted of six children undergoing cancer treatment, aged between eight and twelve years. The Children's Depression Inventory (CDI) and three laughter therapy workshops were applied. A descriptive analysis was performed, with measures of central tendency for quantitative variables and absolute and relative frequencies for categorical variables. RESULTS: The results indicated that 83% of the children presented an emotional problem due to the disease; favorable changes were evidenced in the depression scores after the laughter therapy interventions. CONCLUSIONS: It is concluded that laughter therapy is an effective non-pharmacological treatment when combined with workshops aimed at strengthening the expression of emotions, self-esteem and life project, which not only improves the health of children, but also prevents and reduces the appearance of emotional disorders.

Does online communication mitigate the association between a decrease in face-to-face communication and laughter during the COVID-19 pandemic? A cross-sectional study from JACSIS study.

Laughter has a protective effect on human health. The spread of coronavirus disease 2019 (COVID-19) has changed opportunities for face-to-face communication and might decrease opportunities for laughter. This cross-sectional study aimed to investigate whether the decrease in face-to-face communication during the COVID-19 pandemic is associated with a decrease in laughter. Additionally, we investigated whether an increase in online communication mitigates this association. Data from the "Japan COVID-19 and Society Internet Survey (JACSIS)," conducted between August and September 2020, were used. Participants aged 15-79 years were included in this study. The outcome was a decrease in laughter before the onset of the COVID-19 pandemic. The explanatory variables were decreased face-to-face communication with friends and increased online communication (text message, telephone, and video contact). Causal mediation analysis was used to calculate prevalence ratios (PRs) and 95 % confidence intervals (CIs) of the controlled direct effects of increased online communication. Furthermore, the proportions eliminated (PEs) by an increase in online communication were calculated. Among the 25,482 participants, 40.4 % had decreased face-to-face communication and 21.4 % had a decreased frequency of laughter. After adjusting for confounders, a decrease in face-to-face communication was significantly associated with a decrease in laughter (PR = 1.62, 95 %CI = 1.55-1.70). PEs for decrease in laughter were 27.2 % (95 %CI = -2.0 to 56.4) for text-based communication, 36.1 % (95 %CI = 12.3-59.8) for telephone-based communication, and 28.6 % (95 %CI = 0.6-56.6) for video-based communication. Although a decrease in face-to-face communication was associated with a decrease in laughter during the COVID-19 pandemic, online communication, particularly telephone-based communication, mitigated this association.

Understanding mixed emotions in organized helping through emotionography.

Introduction: Emotionography studies emotion: (a) as it occurs naturally in display, reception, attribution, and avowal; (b) within and across diverse stretches of interaction and varied institutional contexts; (c) grounded purposefully in the perspectives of the interactants as those perspectives are displayed in real-time through unfolding talk; (d) using materials that are recorded and transcribed in sufficient precision to capture the granularity consequential for the interactants. We overview contemporary research on "mixed emotion" highlighting theoretical and methodological issues and explore the potential of emotionography as a generative alternative. Methods: The analysis will use contemporary conversation analysis and discursive psychology to illuminate the workings of organized helping using a collection of recordings from a child protection helpline all of which include laughter alongside crying. Results: Analysis shows, on the one hand, how crying and upset display the caller's stance on the trouble being reported, and mark its action-relevant severity; on the other, how laughter manages ongoing parallel issues such as advice resistance. We show that the "mixture" is public and pragmatic, displaying different concerns and stances, and dealing with different issues; all is in the service of action. Discussion: When analyzing the specifics of interaction, the concept of "mixed emotion" loses clarity, and it is more accurate to observe competing pragmatic endeavors being pursued in an intricately coordinated fashion. These practices would not be captured by conventional emotion measurement tools such as scales, vignettes, or retrospective interviews. Broader implications for theories of emotion and methods of emotion research are discussed.

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.

Reduced number of teeth with and without dental prostheses and low frequency of laughter in older adults: Mediation by poor oral function.

PURPOSE: Laughter is expected to have health-protective effects, but the potential link between tooth loss and laughter remains unclear. Therefore, this study aimed to examine the association between tooth loss and a low frequency of laughter among older adults in Japan, to elucidate whether this association could be mitigated by dental prostheses, and to evaluate the magnitude of the association mediated by poor oral function. METHODS: We used cross-sectional data from 157,708 functionally independent participants aged ≥65 years (46.3% male) from the Japan Gerontological Evaluation Study. A modified Poisson regression model was applied to examine the association between the number of remaining teeth (≥20/10-19/0-9), dental prostheses use, and infrequent laughter (i.e., laughing never or almost never). Causal mediation analysis was performed to assess whether the association was mediated by difficulties in eating hard foods, choking, or dry mouth. RESULTS: Among the participants, 9,129 reported infrequent laughter. Participants with ≤9 and 10-19 teeth who did not use dental prostheses had a 1.29 and 1.14 times higher likelihood of infrequent laughter than those with ≥20 teeth, respectively. Furthermore, difficulty eating hard foods, choking, and dry mouth mediated 22.8%, 0.4%, and 4.3% of the association between fewer remaining teeth and infrequent laughter, respectively. Meanwhile, we did not find evidence for the differences in infrequent laughter between participants with ≤19 teeth using dental prostheses and those with ≥20 teeth. CONCLUSIONS: Tooth loss among individuals without dental prostheses was associated with infrequent laughter, and this association was mediated by poor oral function.

Is laughter the best marketing? Why this is the wrong question.

Humor is often described as a miracle pill for marketers, yet the effects of humor on advertising, content marketing, service, and other marketing functions are wildly inconsistent. Before scholars can know whether a pun, prank, meme, or laugh will attract sales, clicks, or five-star reviews, they need to understand why the effects of humor appear to vary. Humor has different effects because scholars have treated humor as different constructs while studying how it influences different marketing outcomes with different types of stimuli in different of situations on different types of people. Only by recognizing these differences can scholars begin to understand when, why, and how humor can benefit marketers. To navigate this complexity, researchers need to develop a theory of humor that can help explain how different attempts to be humorous influence different consumers in different situations.

Humor, hypnosis and kids.

Bertrand Russell, philosopher and Nobel prize winner said "Laughter is the most inexpensive and most effective wonder drug. Laughter is a universal medicine." Humor as medicine may be just what the doctor ordered to keep us emotionally, mentally and physically fit. Children are not only wonderful hypnotic subjects, they love laughter and silliness. The therapeutic effectiveness of hypnotherapy with children and adolescents can be enhanced when humor is incorporated into the session. Laughter is fun and free and can be used to strengthen rapport and the therapeutic alliance between the clinician and the child. The neuro-psychological development in children necessary for the appreciation and development of humor will be discussed along with how and why humor and hypnosis can be combined to increase therapeutic effectiveness.

The Levels of Auditory Processing during Emotional Perception in Children with Autism.

BACKGROUND: The perception of basic emotional sounds, such as crying and laughter is associated with effective interpersonal communication. Difficulties with the perception and analysis of sounds that complicate understanding emotions at an early development age may contribute to communication deficits. METHODS: This study focused on auditory nonverbal emotional perception including emotional vocalizations with opposite valences (crying and laughter) and neutral sound (phoneme "Pᴂ"). We conducted event-related potential analysis and compared peak alpha frequencies (PAFs) for different conditions in children with autism spectrum disorder (ASD) and typically developing (TD) children aged 4 to 6 years old (N = 25 for each group). RESULTS: Children with ASD had a higher amplitude of P100 and lower amplitude of N200 for all types of sounds and higher P270 in response to neutral phoneme. During the perception of emotional sounds, children with ASD demonstrated a single P270 electroencephalography (EEG) component instead of a P200-P300 complex specific to TD children. However, the most significant differences were associated with a response to emotional valences of stimuli. The EEG differences between crying and laughter were expressed as a lower amplitude of N400 and higher PAF for crying compared to laughter and were found only in TD children. CONCLUSIONS: Children with ASD have shown not just abnormal acoustical perception but altered emotional analysis of affective sounds as well.
