Assessing the Impacts of Yoga Asana – Survey Summary

What’s happening in yoga?

I am really excited to share the information obtained from our yoga asana injury survey. First, I want to create the context for why I decided to do the survey in the first place. What is the intention here? What efforts did we take to gather the information? Where are we going next?

Before going further, a special thanks to everyone on my side of the screen who helped me make this a survey that contributed real data in a scientific way. A really big thanks to those of you who participated and shared the survey on social media or in other ways.

The idea for this project

When the idea of the survey came about (through a conversation with a good friend), it was just after the William Broad article hit the New York Times. Remember that one? I was appalled by the article as were many other people. I wasn’t appalled so much because there was a suggestion that people could get injured while doing yoga. No, not at all. I’ve been around long enough to observe injuries from doing asana. No, it was the use of obscure and dramatic examples of injuries that seemed (intentionally or not) to imply that on any given day, in any given pose, you might die! Okay, I’m exaggerating. But it left many people with the feeling that serious injuries happened on a daily basis.


I run around the world teaching anatomy to yoga teachers and practitioners. Can you imagine the kinds of questions I got after that article came out? You can read my initial response to the Broad article here (By the way, the book was great). Of course, questioning whether and/or how we are getting injured is totally appropriate, hence the yoga asana survey. What I did not feel was appropriate was the continued use of the article to lead practitioners, unintentionally or not, to believe that dramatic injuries happened on a regular basis!

Injuries do happen

Let me be clear about my position. I have always known that you could get injured while doing asana. I have never lived in an alternate universe where asana can only cure. For years I have described asana as neutral. In fact, I go further and say that the asanas don’t even exist until we do them. Note that WE are attempting, performing, achieving, failing, or injuring ourselves! We may or may not be ready to do them. The full expression of the posture may not be appropriate for us at all given our constitution and structure! There are many reasons, but in the end, it is we who decide to do it. In the end, I am happy that the conversation continues and believe that the data from this survey will help with the very real concerns of yoga practitioners around the world.

Contextualizing injuries

The fact that the conversation continues shows that there is a strong interest among yoga practitioners to better understand the body that we use as a tool for our “spiritual practice” and the impacts that the practice has. Now, let’s see what the numbers say.

In laying out the survey of yoga asana practitioners, I wanted context, particularly around the subject of injuries. In my mind, I was immediately asking questions such as:

  • Was there a prior injury in that area?
  • Was it hot or cold, both inside the room and outside?
  • How old was the practitioner?
  • What other activities did the practitioner do?

There are many other questions we could be asking as well. My point here is that context matters! Just because something happens while doing an asana does not necessarily mean that there aren’t other factors that, if removed completely, would mean that you would not be injured while doing that posture. In addition, I also wanted there to be some sense of what benefits people perceive from performing their practice. So we also asked questions about healing of injuries, as well as changes in habits of lifestyle.

What we hope to do with this project is provide some answers to these questions, and more importantly, add context to the conversation. Yoga asana practice does not occur in a vacuum. Our past health and movement histories, as well as the activities we do concurrently with yoga, impact our physical, mental, and emotional experiences.


Hours were spent on the experimental design for this yoga asana survey. When we launched it, we also wanted to do so in the most unbiased way possible. We painstakingly chose the words that went with the image and title. This was on purpose. To begin distributing the survey, I reached out to Yoga International. They were willing to write a brief article and share it across their social media. Their audience provided a good cross-section of the diverse international yoga community. I also reached out to the broader yoga community via the Yoga Alliance directory, my Facebook page, my personal page, and my newsletter list.



We had 2,628 people take the self-administered survey! The self-reporting nature of the survey and its data should always be taken into account as we describe relationships in the data and extrapolate to discuss what people are experiencing in yoga.

The total sample size was large enough (> 400 completed surveys) to control for the necessarily opportunistic nature of the survey distribution and voluntary completion. Our resulting sample size allows for statistical analysis of relationships in the data at α=.05 (95% confidence level).

Although the initial intention of the survey was related to the topic of injuries we also wanted some space for positive outcomes of practice. We had five primary questions related to injuries. Of those five,  participants could choose either one, two, or three injuries. Each of those had eighteen sub-questions related to that injury. We asked four primary questions related to positive outcomes of asana practice. One of those four had two sub-questions. We asked additional questions about the general health and activities of participants.

What this means to you

We now have actual data that speak to the impacts of asana practice. This is completely different than putting a message out on Facebook and saying something like: “If you’ve ever been injured while doing asana, I’d like to hear about it.” While that might encourage people to come forward to tell their story, it says little about overall trends in the impacts of asana practice, positive or negative.

We’ve now published a series of posts related to the yoga asana injury survey data on In addition, we published two peer-reviewed journal articles that share the project results at a greater level of detail than covered in the articles here. We published one on injuries in yoga and another on yoga’s benefits.

Let’s get to the data!

Who responded to our yoga asana survey?

A total of 2,628 respondents answered some portion of our survey!

Our respondents live in 67 different countries! The greatest number (n = 2628) were from the United States (40.4%), followed by the UK (16.7%), followed by Canada (4.5%).

yoga asana survey age

Respondents identified themselves as primarily female (n = 2625, 84.5%) and between the ages of 31 and 55 (n = 2625, 70%).

yoga asana survey gender

Their primary reason for starting a yoga practice (n = 2483) was physical (54.5%), although mental and emotional reasons for starting practice also resonated (25.1%).

A large percentage of respondents also do other yoga practices in addition to asana (n = 2615), like pranayama (72.5%) and seated meditation (67.8%).

Respondents to our yoga asana survey tended to be long-term practitioners of yoga asana (n = 2624). Forty-five percent stated that they had been practicing for more than 10 years. An additional 36.2% stated they had been practicing for 4-10 years. More than half of respondents (60.1%) reported that they also teach yoga (n = 2620).

Among styles of practice (n = 2624), Ashtanga practitioners (in the style of Pattabhi Jois) were heavily represented in our survey (60.1%). The second-largest group reported that they practiced hatha (34%) and the third-largest group practiced vinyasa or power yoga (29.3%). We recognize that the number of respondents who reported practicing Ashtanga is likely an artifact of the outlets that we used to contact potential survey participants. We adjusted for this potential bias when we examined relationships in the data set.

Where can you see the results?

**A Note on Statistics: For each descriptive statistic we included in our summary post, we also included a number “n” in parentheses (n=). This indicates the number of people who responded to each individual question reported in our summary statistics. We calculated percentages for an individual question based on the number of people who answered that question. This varied from question to question as not everyone answered every question.
