I’m going to be a little blunt today—
A horse yawning during your session does not mean you “released” anything.
I don’t know when this became the standard, but somewhere along the way we decided:
Horse yawns = good bodywork.
And now it’s everywhere.
Videos. Reels. Marketing.
People pointing to a yawn like it’s proof something meaningful happened.
It’s not.
Yawning is a neurologically driven behavior, regulated by the brain—not the muscle, not the fascia, not the joint (Baenninger, 1997; Walusinski, 2006).
Yes, you might see a shift in state—a nervous system shift from sympathetic (fight or flight) to parasympathetic (rest and digest). So yes, the horse might drop into a more parasympathetic moment.
But let’s not confuse that with actual change.
Because a horse can yawn and still:
• move the same
• compensate the same
• load the same
• feel exactly the same on palpation
So what, exactly, did we “release”?
Horses also yawn with fatigue, transitions, anticipation, arousal, and discomfort. It’s not a clean or specific signal—and it’s definitely not a measurement tool (Fureix et al., 2011).
And this is where I’m going to push a little—
Using a yawn as proof your work was effective isn’t clinical reasoning.
That’s not assessment—that’s filling in the gaps with what you want to believe happened.
We’ve leaned into it because it’s visible.
Because clients recognize it.
Because it feels like something happened.
But visible does not equal meaningful—even if it feels good to witness and seems more “tangible.”
And don’t get me wrong—nervous system shifts matter. They shouldn’t be dismissed.
But they also shouldn’t be used as standalone proof of tissue change.
If you actually want to know if your work did something, you have to look deeper:
• tissue quality
• range of motion
• posture and load
• movement
• and what that horse looks like 24–72
hours later
If a horse yawns—fine. Note it.
But building your entire interpretation around it?
That’s storytelling.
Back it up by feeling real changes—and then seeing how the horse holds those changes over time.
In a nutshell, not everything that looks like a release… is one.
I’ll follow this up with what I actually consider a “release” and how to recognize it in a way that holds up clinically.
What are you using to actually measure change in your sessions—beyond visible reactions?
