CW: mention of BMI and body weight in a medical study on laughter yoga.
Since yoga took off in North America, teachers and studio owners and social media hopefuls have trotted out every possible variation to make it more attractive to more people. I’m not talking about Kundalini yoga, Iyengar yoga, etc.
No, in this case, I’m talking about yoga with music, yoga with wine or beer or cocktails, goat yoga, bro yoga, naked yoga, yoga dance, etc.
One type of yoga I hadn’t heard of until last week was laughter yoga. Yes, this is a thing. Dr. Madan Kitaria is credited with inventing it, and this site goes into loads of detail about him and about what laughter is alleged to do to us and for us. In short, laughter yoga is supposed to lower stress and anxiety, provide ease from depression, release endorphins, and generally relax us.
If you’re interested in a demonstration of laughter yoga, here is a TED talk (of course there’s a TED talk!) that you can watch.
Okay, I get it: yoga is good for you. Laughing is good for you. So, laughing while doing yoga must be extra-good for you. And yet I maintain a smidge of skepticism. Why?
Lots of scientists and sciency-folks have been speculating about the role of laughter in health and well-being for decades. In this Shape article (an authoritative source if ever there was one), we get this capsule history of laughter as medicine (forgive me, I got lazy while googling):
William Fry, a professor of psychology at Stanford University, helped to pioneer the research on the health benefits of laughter back in the 1960s. Fry found that laughter enhanced the activity of immune system cells through an experiment in which he drew blood at regular intervals while watching comedies. In author Norman Cousins’ 1979 book, Anatomy of an Illness, he described how he battled a fatal disease for years through his practice of mindful laughter. And psychotherapist Annette Goodheart published a book titled Laughter Therapy in 2006 that included 25 ways to help yourself laugh about everyday things.
It makes sense that people hope to leverage laughter to bring down blood pressure, cholesterol, blood sugar, cortisol levels, you name it. So far, the research suggests diffuse and bidirectional effects– laughter may affect well-being, and feeling better influences frequency of laughter. For instance, in a 2021 study of the relationship between oral health and laughter, the researchers found
The participants with 10 or more teeth were significantly more likely to laugh compared with the edentulous participants, after adjusting for all covariates… There was a significant bidirectional association between frequency of laughter and oral health that was independent of socioeconomic and lifestyle factors among older adults.
Which is to say: people with more teeth laugh more, and people who laugh more have more teeth.
I bring up actual laughter research because last week, while perusing the weekly newsletter on body weight and metabolism research, I found this study:
Curious, I read the article. Twice. Here’s what I found:
The researchers tried out a 12-week program of 60-minute laughter yoga classes and 30-minute rakugo performances (a traditional form of Japanese comic storytelling). The participants were mostly women over 60, and they had some standard risk factors like high blood pressure or cholesterol, diabetes, or slightly higher body weights (overweight according to researchers and adjusted BMI scale). The control group just went about their business, with no intervention.
So what did the researchers find?
The intervention group laughed a lot more. Their responses to all sorts of quality-of-life health surveys after the 12 weeks were a bit higher than the control group’s. The laughter yoga and comic performances seemed to do them good.
But laughing a lot didn’t really affect their body weight. The researchers document some teeny-tiny shifts in BMI– shifts which they acknowledge aren’t clinically significant. The men in the intervention group– which were 2% of the group (yes, I wrote that correctly) experienced stronger effects overall, but even their effects were very small. So much for laughter yoga as weight-loss method. This is entirely unsurprising.
However, that doesn’t mean that laughter yoga should be dismissed; far from it. It seems to be a way to introduce some people to both gentle movement and breathing techniques that reduce stress and improve mood and feelings of well-being.
Here are a couple of laughter yoga exercises you can try in the privacy of your own bathroom. I took them from the knowledgeable folks at Shape (obvs):
Smile-Ups: Stand in front of a mirror, or even better, face to face with a friend or family member. Practice breaking into a big smile 10 times. You can also do this when confronted with a stressful situation, such as being stuck in traffic.
Hand Puppet: Struggling with negative self-talk? Get rid of it by acting it out. This exercise, which you can also call the “I love myself” laugh, helps you to recognize the silliness of those thoughts. Lift up one hand and imagine it’s a hand puppet, and start putting those negative thoughts into words using a funny voice and moving your hand puppet accordingly. Then, take your other hand and “squash” the hand puppet with laughter.
Readers, have any of you tried laughing yoga? Did you try the smile-ups or the hand puppet negative self-talk? Let me know.
