I don't know how anyone could live in the east without air conditioning, especially on the higher floors of apartment buildings.
Your liver is probably grateful. If a Pole ever offers you home made wine, graciously accept then dump it down the drain when they're not looking! My partner is a first generation immigrant from Pierzchnica. She came on a student visa, loved Canada, got her PR then citizenship. That was before we met. She doesn't have the drinking superpowers like other Poles... thank god! She can smoke weed like a champ tho.
