About

Premenstrual syndrome (PMS) is a common condition among young women, characterized by physical, emotional, and behavioral symptoms that negatively affect quality of life. Laughter yoga, a non-pharmacological mind-body intervention combining breathing techniques, relaxation, and intentional laughter, has been shown to reduce stress, improve mood, and enhance well-being. This randomized controlled trial aims to evaluate the effect of laughter yoga on PMS symptoms and quality of life in young women.

Full description

The menstrual cycle is a physiological process that begins at puberty and continues until menopause. PMS is a recurrent condition that occurs in the luteal phase of the cycle and subsides with menstruation. It is associated with a wide range of psychological, physical, and behavioral symptoms, including irritability, depression, breast tenderness, bloating, sleep disturbances, and decreased academic or social functioning. These symptoms significantly impair daily activities and reduce quality of life, particularly in young women.

The prevalence of PMS varies across populations, but studies consistently indicate that approximately half of young women experience moderate to severe symptoms. In some cases, these symptoms result in absenteeism, reduced productivity, and academic difficulties. The most severe form, premenstrual dysphoric disorder (PMDD), affects a smaller proportion of women but has a profound impact on functioning.

Management of PMS includes both pharmacological and non-pharmacological interventions. Pharmacological treatments such as oral contraceptives, antidepressants, and hormonal therapies may provide relief but often cause side effects and are not always preferred by young women. Non-pharmacological approaches, including relaxation techniques, exercise, yoga, and complementary therapies, are increasingly considered due to their accessibility and fewer side effects.

Laughter yoga is a mind-body practice developed in the 1990s, combining breathing exercises, playful activities, and simulated laughter that soon turns into genuine laughter. The brain does not distinguish between spontaneous and voluntary laughter, and both can induce positive physiological and psychological effects. Research has shown that laughter yoga reduces stress, enhances immune function, increases endorphins, and promotes overall well-being. It is a simple, cost-effective, and sustainable intervention that can be applied individually or in groups.

Although laughter yoga has been studied in relation to stress reduction, mood enhancement, and chronic disease management, there is limited evidence regarding its specific effects on PMS. Preliminary findings suggest potential benefits in reducing PMS-related distress, but no randomized controlled trial has comprehensively examined its impact on both PMS symptoms and quality of life.

This randomized controlled trial is designed to address this gap. The intervention group will participate in structured laughter yoga sessions guided by a certified instructor, while the control group will receive no intervention during the study period. PMS symptom severity and quality of life will be assessed using validated scales at baseline, during the intervention, and at follow-up.

The study aims to provide scientific evidence on the effectiveness of laughter yoga as a non-pharmacological approach in PMS management. By evaluating both short-term and sustained effects, this trial seeks to contribute to women's health literature with an innovative, low-cost, and accessible intervention. The findings are expected to inform clinical practice and support the integration of laughter yoga into nursing and women's health care for improving symptom management and quality of life in young women.

intervention arm

Experimental group

Description:

Intervention arm: Laughter yoga group sessions will be implemented twice a week for 4 weeks (8 sessions in total); the first session will be \~45 min, the subsequent sessions \~30 min. Sessions will be conducted face-to-face in a suitable room within the institution. Following the interim measurement in week 4, the intervention arm will continue structured individual laughter practices daily for 4 weeks.

Treatment:

Behavioral: laughter yoga

control arm

No Intervention group

Description:

No intervention will be applied to the control arm; after the post-tests, the same training will be offered to this group for ethical reasons (delayed intervention).
