The main reason for the change is that this make cryox intentionally really good in deep crit and makes it basically impossible for you to die, if cryox didnt heat you up it just seems really tedious for antags trying to deal with someone who just popped a cryopill trying to kill them with the oxy healing and reduced death chance.
