Stage 1 (initial cold shock) occurs in the first 3-5 minutes of immersion in cold water. what can happen during stage 1 of cold water immersion?

i can't answer your question in very sad situation.

but if your situation is very bad, then you can find happiness by thinking about your past that has full of happiness.

or you should do meditation for some time to get rid off from that bad situation.

when you rub, you also apply pressure, that pressure can urge the poop to come out. i think that when your rubbing, you also might be slightly breaking it up and that can further fill the stomach.
