very hot day in Padova

Chicco told me today in Padova, it was the hottest day ever. What am I going to do? a/c is not readly used in Italy. I am so used to the N.American way of cooling system, so I know it will be hard to adjust. Anyone else find adjusting difficult? how do you deal with it? Is a/c expensive to have in Italy? I guess time will tell.
