If you can stand it, cold therapy can really condition your body to tolerate it a lot more. You don't even need to go full ice bath, just stand in the shower with the water as cold as you can take it for at least 2 - 4 minutes. You'll learn to control your breath to generate heat and with practice will become much more cold tolerant, especially acutely for the hour or so following the session. Not fun but there's some evidence for modest health benefits as well...might be worth a try.
