When I lived in a top floor apartment in Melbourne, where it regularly hit 40°C without any air-conditioning (still unsure how that was and is legal to rent out), I would use a spray bottle of water and a fan to evaporatively cool myself, cold showers to lower my body heat and trips to an air-conditioned space like the cinema or shopping centre during the worst of it.
People from the "hotter" regions, how do you deal with the heat?
I am from Eastern Europe and this is the hottest summer on my memory. For at least 3 consecutive years the heat is breaking all records....
