It's obvious to me but maybe not to others why this could help someone who is quitting drugs. The ice bath releases adrenaline and Krank said dopamine as well. both of which obviously are anti-depressive. Same reason insulin shock therapy was a common anti-depressive treatment in asylums a long time ago; you induced hypoglycemia with insulin injections to the point of the patient passing out and then poured sugar into them. The stress response releases a ton of adrenaline and it was thought it "rebalanced" neurotransmitters. I used to do this to myself for fun and games Another tactic to make life more colorful is dopamine deprivation to sensitize yourself to stimuli, e.g. no internet like tiktok reels, no music, bland food with no salt or spices, no sex... then when you introduce say spices it's pure heaven LOL.
