Laughter Yoga, Cortisol, and Menopause: What a Trial Shows

A small randomized trial found that a group program combining self-care education with laughter yoga lowered salivary cortisol, perceived stress, and menopausal symptom scores in postmenopausal women. That objective cortisol result makes the study more interesting than another questionnaire-only wellness claim. It does not, however, show that laughter yoga itself caused the change.

The trial tested a bundle: education about maintaining, monitoring, and managing self-care during menopause, plus laughter yoga delivered in a group setting. Participants may have benefited from any part of that package—or from regular social contact and attention. The result supports structured group stress management. It cannot tell a reader whether laughter yoga, education, or both deserve the credit.

What the menopause trial found

Gülevi et al.'s 2026 randomized controlled trial assigned 64 postmenopausal women to an intervention group (32 participants) or a control group (32 participants). The intervention combined a self-care-based menopause education program with laughter yoga. After the intervention, the published abstract reports statistically significant improvements in salivary cortisol, perceived stress, menopausal symptoms, and coping-related outcomes in the intervention group compared with controls.

That is a meaningful design advantage over an uncontrolled before-and-after program: random assignment helps reduce baseline differences between groups. Cortisol is also a biological measurement rather than a self-reported feeling. Still, cortisol is a stress-related biomarker, not a direct measure of health, and lower is not automatically better in every context. Its meaning depends on when and how it was measured and on the person’s daily cortisol pattern.

The abstract does not report effect sizes, confidence intervals, the cortisol collection schedule, or follow-up after the program ended. It therefore cannot show how large the changes were, how precise the estimates were, whether they were clinically important, or whether they lasted.

The central problem: the study tested a package

Every participant in the intervention group received both self-care education and laughter yoga. There was no laughter-yoga-only group, no education-only group, and no attention-matched group activity without those ingredients. This makes causal attribution impossible.

Self-care education could plausibly reduce stress by giving participants practical ways to recognize symptoms and respond to them. Laughter yoga could affect mood, breathing, physical activation, and social connection. Group attendance itself can change stress biology. Participants may also expect a supportive program to help, which can influence symptom ratings and behavior.

That last possibility is not a trivial footnote. A 2023 observational study of teachers found that social isolation was related to patterns of diurnal salivary cortisol on both workdays and leisure days. Teachers are not menopausal women, and an observational study cannot prove that joining a class changes cortisol. But it supplies a biologically plausible reason to treat social contact as an active ingredient rather than background scenery.

The trial’s practical lesson is therefore broader than "laughter lowers cortisol." A recurring, group-based program that combines education, activity, and social engagement may help women dealing with menopausal symptoms. The specific contribution of laughter yoga remains unknown.

Why laughter yoga remains plausible—but unproven here

Laughter yoga has a prior evidence base outside menopause. A 2021 randomized trial in first-year nursing students found that laughter yoga reduced mental symptoms and salivary cortisol compared with a control condition. That supports the possibility that laughter-yoga sessions can affect stress-related outcomes in stressed adults.

It does not establish the same effect in postmenopausal women. Nursing students face acute academic stress in a much younger population. Menopause involves a different hormonal environment, symptom pattern, and likely pattern of chronic stress. The student trial also does not provide an effect estimate in the available abstract, so it cannot supply a numerical benchmark for the menopause study.

A 2024 systematic review of nurses and nursing students reported directionally favorable results for laughter yoga across health measures, including stress-related outcomes. The review expands the plausibility case, but it does not pool a cortisol effect specific to menopausal women. A separate 2026 pediatric systematic review describes the usual laughter-yoga format: warm-up clapping, deep breathing, play activities, and structured laughter, often in 30- to 40-minute sessions over about eight weeks. That describes the practice; it does not establish an effective dose for menopause.

Cortisol needs more context than one number

Cortisol changes sharply over the day. The cortisol awakening response, later-day decline, recent food intake, posture, and the time since waking can all affect a salivary result. A single sample collected at an unspecified time can reflect the moment of collection rather than a lasting change in hypothalamic-pituitary-adrenal activity.

That issue matters especially in midlife women. A 2024 observational study by Rulu et al. found that fingernail cortisol, which integrates cortisol exposure across several weeks, was associated with midlife symptoms and household stress. This does not invalidate salivary cortisol. It does mean longer-integration measures and multi-sample daily profiles can answer different—and often more useful—questions about chronic stress.

Sex-specific cortisol dynamics add another layer. A 2026 study of daily and chronic psychological stressors reported sex differences in diurnal cortisol responses. The menopause trial enrolled women, but its abstract does not describe sex-specific reference methods or a diurnal sampling design. That omission limits physiological interpretation of the reported cortisol reduction.

Why cortisol is relevant to menopausal symptoms

The rationale for studying stress in menopause is sound. A 2025 observational study of midlife women found that heightened menopausal symptoms mediated the association between stress and depressive symptoms. The finding describes an association and a modeled pathway, not proof that changing cortisol will treat depression or menopausal symptoms. It does show why stress management belongs in the conversation.

Symptoms, stress, sleep, mood, caregiving demands, and social support can move together. A program that helps participants feel more capable, connected, and less distressed may improve several questionnaire outcomes at once. That pattern is valuable to study, but it also raises the chance of false-positive findings if investigators test many outcomes without appropriate adjustment. The available abstract does not report the statistical plan for multiple comparisons.

How to use this evidence

Consider laughter yoga a reasonable optional component of a social stress-management routine, not a proven standalone cortisol treatment for menopausal symptoms. If the group feels enjoyable rather than performative, that is a practical advantage. A practice people attend consistently has more chance of helping than a perfect protocol gathering dust beside the resistance bands.

The trial supports the combined program. It does not identify which component changed cortisol or symptoms, and it does not establish lasting benefit.

For self-trackers, one random salivary cortisol test is a weak scorecard for chronic stress. A diurnal schedule that includes waking, roughly 30 minutes after waking, and late afternoon is more informative than an isolated sample; longer-integration measures such as fingernail cortisol address a different time scale. Even then, hormone data should complement symptom tracking and clinical care, not replace them.

The next useful trial would compare education alone, laughter yoga alone, their combination, and an attention-matched social group; it would also prespecify repeated cortisol sampling and follow participants after the program ends. Until then, the honest conclusion is modest: this bundled group program improved stress-related measures in one 64-person trial, while the distinct role of laughter yoga remains unsettled.
