Study reveals effectiveness of laughter therapy against depression and anxiety and indicates ideal period for treatment
Recent international research has confirmed the effectiveness of laughter therapy as a practical and beneficial approach to treating psychological problems such as depression and anxiety. The work, which also established an ideal period for intervention, offers new perspectives for those looking for alternatives to alleviate mental suffering.
The study was led by Chia-Yu Liu and his team at Asia University in Taiwan. The results were published in the online edition of the *Journal of Psychiatric Research* on April 16, 2026.
How Researchers Evaluated the Effectiveness of Laughter as Therapy
To deeply investigate the effects of laughter therapy, researchers employed advanced methodologies. They integrated clinical trial sequential analyzes (TSAs), a technique that strengthens the robustness of evidence by examining data from multiple studies. Furthermore, they used dose-response meta-analysis to precisely define the most appropriate duration for treatment.
The systematic review behind the research involved consulting large academic databases. Among them were PubMed, EMBASE, PsycINFO and the Cochrane Library, ensuring broad coverage of existing scientific literature on the topic.
Proven benefits of laughter for depression and anxiety
The scientific validation of laughter therapy marks an important advance in the field of mental health. The technique is recognized for promoting the release of endorphins, neurotransmitters that generate a feeling of well-being and act as natural painkillers. This physiological action directly contributes to reducing stress and anxiety, as well as improving mood in cases of depression.
Acceptance of therapy as a non-pharmacological method offers a valuable option. Many patients seek complementary treatments that minimize the side effects of medications or that integrate with more holistic approaches to health care.
What is the most effective intervention time for therapy?
One of the crucial findings of the research was the determination of the ideal period of laughter therapy intervention. Knowing this duration optimizes treatment results, offering a practical guide for therapists and patients. This allows the formulation of more assertive protocols, avoiding treatments that are too short to produce an effect or prolonged unnecessarily.

Laughter Therapy in the Context of Global Mental Health
The search for effective solutions for depression and anxiety is a global priority, given the worrying rise in mental disorders around the world. Laughter therapy emerges in this scenario as an accessible and low-cost option that can be easily incorporated into different contexts and cultures. By providing robust scientific support, this study elevates laughter therapy from a popular practice to a clinically validated tool.
The simplicity of the technique, which does not require complex equipment or specialized environments, makes it replicable in different communities and groups, enhancing its reach.
Future perspectives for the application and study of laughter therapy
With the new data, the expectation is that laughter therapy will gain more recognition and be integrated into treatment plans more broadly. The study paves the way for future research to explore the detailed neurobiological mechanisms behind therapeutic laughter and its interaction with other treatment modalities.
Researchers can focus on personalizing therapy for different patient profiles and investigating its long-term effects. This could further solidify laughter’s position as an essential pillar in supporting mental health.
