Very interesting.

How quickly can you trigger it?

I've experienced something similar but it takes long time to arrive, at least 5-10 minutes, I wonder if with practice you found exactly the state that triggers it and you can do it instantly.

Also, have you felt it as in waves going up and down? or just located in same place ?

And lastly, does it have any health utility?

- How quickly can you trigger it?

Immediately with a breath (as in start inhaling, it happens). Without a breath, maybe 5 seconds or so?

- Also, have you felt it as in waves going up and down? or just located in same place ?

It's all over the body, although I can focus on just one part of the body and do it there, but that takes me a little longer. (We're still talking about seconds here though. Maybe 20?)

- And lastly, does it have any health utility?

Maybe? Haha, hard to say. If anything probably indirectly, since this has come from a meditation practice, and meditation itself has numerous documented/studied health benefits.

I've been able to do it since I was a young child. One method is by activating the tensor tympani muscles and tensing the front of my neck from my jaw (while making a frowning type facial expression - aka make yourself look like a cardassian) - that's the best way I can describe it. There's another way that involves tensing the base of my skull. I can also move my ears, so I wonder if being able to move that muscle plays into this.

I've been able to do this since I was young. For me, I can trigger it instantly. It's mostly very relaxing. Triggers a yawning response if I do it repeatedly. I think I actually learned it by forcing myself to yawn back then. Feels mind clearing too.

I experience the same, just did it in fact! My ears popped (without yawning) and I didn't realize they needed to equalize but damn if I don't feel more alert now that that's done.
