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

Hearing laughter: a prescription for anxiety relief

Anxiety can have adverse effects on cognition such as impairing test performance or restricting working memory. One way of reducing anxiety is through humor, and the present research investigated if the perception of laughter, which is often seen as a reaction to humor, could impact self-reported anxiety. Participants completed the STAI battery containing subscales for both state and trait anxiety before and after one of three manipulations: a laughter sounds rating task, a neutral sounds rating task, or a working memory span task. Results showed that perceiving laughter decreased both state and trait anxiety, taking a working memory test increased state anxiety, and perceiving neutral sounds had no effect on either type of anxiety. These findings are interpreted as evidence that the positive emotions induced by hearing laughter help to regulate anxiety by undoing arousal, even when negative emotions are not present.

The relation between humor styles and nurse burnout: a cross-sectional study in China

Background

Nurse burnout is a prevalent issue in healthcare, impacting both nurses' well-being and patient care quality. This cross-sectional study examined the association between humor styles and nurse burnout.

Methods

A total of 244 nurses in China completed an online self-report measure to assess their humor styles and burnout levels using the Humor Styles Questionnaire (HSQ) and the Maslach Burnout Inventory-Human Services Survey (MBI-HSS). Spearman correlation analysis and stepwise regression analysis were conducted.

Results

The results showed that affiliative and self-enhancing humor were moderately used, while aggressive and self-defeating humor were rated low among the nurses. Emotional exhaustion was moderate, depersonalization was severe, and personal accomplishment was low. Correlation analyses uncovered significant relationships between humor styles and burnout dimensions. Self-enhancing humor exhibited negative correlations with emotional exhaustion and depersonalization, while aggressive and self-defeating humor styles displayed positive correlations with these burnout factors. Affiliative humor was also negatively correlated with depersonalization. Additionally, self-enhancing humor was positively correlated with personal accomplishment, whereas aggressive humor showed negative correlations with this dimension of burnout. Stepwise regression analysis revealed that self-defeating humor positively predicted emotional exhaustion while self-enhancing humor negatively predicted it. Aggressive humor positively predicted depersonalization, and affiliative and self-enhancing humor also positively predicted this dimension of burnout. Self-enhancing humor positively predicted personal accomplishment, while aggressive and self-defeating humor negatively predicted this dimension.

Conclusion

The findings highlighted the importance of considering different types of humor in understanding the various dimensions of nurse burnout. The use of self-defeating and aggressive humor appears detrimental, while the use of self-enhancing humor may be beneficial in mitigating burnout among nurses.

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.

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 success elements of humor use in workplace leadership: A proposed framework with cognitive and emotional competencies

This qualitative study aims to investigate the competencies and effectiveness of humor use in workplace leadership. By exploring the elements underlying successful and unsuccessful humor use, this research offers insights into the competencies required for leaders to leverage humor effectively. Adopting a qualitative inductive approach, fifteen individual semi-structured interviews were conducted, generating a dataset of 51 critical incidents of humor use. Reflexive thematic analysis was employed to identify key themes, resulting in the identification of five central elements: Reading the context, Intention and motivation, Judgement and decision, Skillful delivery, and Understanding reactions. These elements provide a comprehensive framework for understanding humor use in the context of workplace leadership, emphasizing the importance of cognitive and emotional intelligence / competencies. The study proposes a theoretical framework based on these findings, providing the foundation of a new paradigm for understanding and measuring humor use. This research contributes to a deeper understanding of the competencies and complexities involved in using humor as a leadership tool and provides practical implications for leaders aiming to enhance their leadership effectiveness through humor.

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.

Recognition of emotions in German laughter across cultures

Laughter conveys a wide range of information relevant for social interaction. In previous research we have shown that laughter can convey information about the sender's emotional state, however other research did not find such an effect. This paper aims to replicate our previous study using participant samples of diverse cultural backgrounds. 161 participants from Poland, the UK, India, Hong Kong, and other countries classified 121 spontaneously emitted German laughter sounds according to the laughter type, i.e., joyful, schadenfreude, and tickling laughter. Results showed that all participant groups classified the laughter sounds above chance level, and that there is a slight ingroup advantage for Western listeners. This suggests that classification of laughter according to the sender's emotional state is possible across different cultures, and that there might be a small advantage for classifying laughter of close cultural proximity.
