- 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.
