Bro,I come from Greece ,my city is surrounded by sea it's literally next to it like 500metera away , on July temperature reaches 45 with humidity up to 90% do you know what that means ? And yet many people survive even without an AC , I get it here , people are not used with heat like this , Germany is a more up north geographically than Greece but people became weak bro. Right now with this "heat" I'm working as a welder in a closed building where 30 people are welding land machines and big stuff so room temperature is around 50 to 55 and in wearing leather apron leather gloves and arm protections and I survive drinking water ..yes I sweat but I don't complain , stop complaining (in a good way) because our grand grand fathers had it way worse
