Have lived in Ohio, Florida AND Texas. Heat and humidity in Ohio can be very uncomfortable. In Florida, it can be smothering and depressing. In Texas, on the Gulf Coast, its just plain crushing and unbearable.
In high summer, you plan each day based on the spending the shortest amount time running between air conditioned environments. You go from air conditioned house to air conditioned car to air conditioned store and then back again. When finished you feel like you've completed a full EVA mission in a hostile environment... and you have!
I mean people have fully airconditioned homes, INCLUDING their garages, just so they don't keel over getting into the car before its air conditioning kicks in.
