The Four Minute Mark
In a long Yin hold, something tends to shift around the four-minute mark.
Not always, and with every student. But often enough that I am here writing about it. But also because there is a reason behind that shift I want to tell you about, because maybe, as a teacher, you have seen it or felt it in the yoga space.
As a teacher, you may notice the room gets quieter, not because students have stopped fidgeting and found stillness, but because something in the body’s response to the sustained passive load found in Yin asana begins to settle them.
So what is it?
In the first few minutes of a Yin hold, most students are actually bracing. It is not happening consciously, or at least not entirely consciously, but it is happening. The muscles around the joints contract slightly, the breath tends to be shallower, and there is a heightened vigilance in how the body meets that load. This is the nervous system on guard; it is vigilant. When something unfamiliar arrives, like a long yin asana, the nervous system is assessing, protecting, and holding a little back in reserve, not that this is a problem we need to fix, but it does give us information as teachers and practitioners.
Bracing is not the same as resistance, nor is it the same as pain. It is the body’s way of saying, “Look, I am not sure about this yet.”
And those first minutes of a long Yin hold often involve a little bit of negotiation between the body’s impulse to protect itself and the student’s invitation to stay with it.
Around the four-minute mark, for many students, that negotiation can begin to resolve itself. The parasympathetic branch of the autonomic nervous system has arrived more fully, and things can begin to settle. The breath rate often slows down, tension around the hips may begin to fall away, and those areas that were bracing move towards a depth that feels safe and ok.
This is important in Yin yoga because depth in a Yin hold is not the same as a deeper range of motion. A student can physically move further into a posture but still be bracing. A student can appear to be at a modest depth but be completely relaxed. What you are seeing when you look at a student in a long hold has nothing to do with their range of motion; it is entirely about the quality of the nervous system’s response to that load and whether it consents or is on the fence and still deciding.
As teachers, we cannot instruct depth; we can give a cue that invites it, but it is up to the nervous system whether it goes there or not. And it happens only when the body moves from ‘No, not yet’, to ‘yes, it’s ok, and I am ok here’. As teachers, we can create many conditions to foster that sense of safety in the room, but it often goes way beyond verbal cues and lighting alone.
None of this is predictable; it has to do with whether the student feels safe in their body, whether they are holding something they have yet to find the words for, and whether their four-minute mark looks very different or simply does not come at all. And for us as teachers, how we hold the room in that moment matters more than most of us realise; it is not incidental to the teaching, it is the teaching.
We set the tone for class through co-regulation. Our own autonomic state sets a tone, and when we are genuinely settled, students’ nervous systems read it. When we are performing calm while running mild anxiety underneath, that information travels too. I say this as someone who has taught through some of the most unsettled periods of my own life, often without my students knowing anything was wrong. My performance was good, but the co-regulation was not.
All teachers perform sometimes, and this is not a failure by any means. But understanding the nervous system science is what gives us a way back from performing. Not by demanding that we be settled before every class, but by helping us understand what is actually happening when we are not. That knowledge is what, over time, gives us somewhere to teach from that is more genuinely ours and honest. And I will tell you, it all begins with our own practice, and the best place to start is together.
If you want to come and think about some of this together, I am running a free lecture on 16 June at 19:00 UK. The details and registration are here:
