Laughter yoga

Laughter yoga is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Laughter yoga rather than just read about it. In short: Laughter yoga (Hasya yoga) is a laughter exercise program which emphasizes three elements: laughter & playfulness, yogic breath-work, and mindfulness meditation. Laughter Yoga was introduced in Mumbai, India in 1995 by family physician Madan Kataria and his wife Madhuri.

Key takeaways

Laughter yoga belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Laughter yoga to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Laughter yoga from memory before moving on to harder problems.

Reference excerpt

Laughter yoga (Hasya yoga) is a laughter exercise program which emphasizes three elements: laughter & playfulness, yogic breath-work, and mindfulness meditation. Laughter Yoga was introduced in Mumbai, India in 1995 by family physician Madan Kataria and his wife Madhuri. Kataria modernized some of the work of earlier laughter pioneers, who taught very similar concepts starting in the 1960s, in a more structured and a unique manner. Kataria, his wife Madhuri and three of their best friends started the first laughter social club at a local park. To keep the laughter flowing (after they ran out of jokes), Kataria created the 40 Foundation exercises, which are based on everyday situations, rather than on jokes or comedy. Kataria wrote about his experience in his 2002 book Laugh For No Reason. Additional scientific data and updated information can be found in Kataria's 2021 book, Laughter Yoga: Daily Laughter Practices for Health and Happiness. Laughter yoga is found in 120+ countries. There are thousands of Laughter Yoga clubs worldwide, in-person and virtual.

Method Practitioners choose to laugh for their health. Laughter Yoga is performed without any humorous reason to laugh, with one practitioner observing that "the body does not know that we're faking it." Breathing exercises are used to connect to the diaphragm and to prepare the lungs for laughter. What follows are a series of 'laughter exercises' that combine gentle improvisational movements and playful visualization techniques. Laughter exercises are interspersed with breathing exercises.

Benefits A 2018 review concludes that group interventions based on laughter Yoga improved depressive symptoms over the short term, but there is no good quality evidence to assess that laughter yoga is more effective than other group-based intervention. A 2019 review and meta-analysis in the field of laughter-inducing therapies suggests that they are more effective than humorous laughter and can improve depression. However, the quality of the evidence was low. A meta-analysis published in 2020 concludes that laughter yoga has no adverse effect and could have benefit for older adults in terms of physical function (blood pressure, cortisol level, sleep quality) and psychosocial health (life satisfaction, quality of life, loneliness, death anxiety, depression, mood, happiness).

Worked examples

Example 1 — a first encounter with Laughter yoga

Start with the simplest possible case. Write down what Laughter yoga claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Laughter yoga before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Laughter yoga ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Laughter yoga

In research: Laughter yoga appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Laughter yoga in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Laughter yoga is common in secondary-school and first-year university syllabi. It links to neighbouring topics Laughter, Yoga styles, so understanding it makes those chapters shorter.
In everyday life: Look for Laughter yoga outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
