 do you want it to be like a sudden cool or, you know, try to stage that out? Because I would think the shock of it could be, you do not want to shock them. I use tepid water. Um, so room temperature to slightly warmer than room temperature water. If it feels room temperature to you, like to the slightly, like, not like you've got a water bottle that you've left on the counter and it's slightly cool room temperature, but like you put your hand in and it feels like nothing, um, because that's going to be slightly cooler than their body temperature.
