is it normal to get teary during breathwork? bit caught off guard

did a longer breathwork session (the faster connected-breathing kind) and about halfway through i just started tearing up for no reason i could point to. wasn't sad exactly, it just kind of came up and out.

talked to the facilitator after and she said it's pretty common, something about the breathing moving stuff that's been sitting in the body. felt a bit raw but honestly lighter after.

how common is this for people? and does it get less intense the more you do it, or not really?
