I am a pansy when it comes to heat. In my house it is always at most 72 degrees Fahrenheit. Studio is in the basement of my house so it is even cooler.
Currently rebuilding my live room and I'm running new duct work so the air has been off all week. Its a 112 year old building with horrible insulation, (the original interrior walls were cardboard) and it hit 105 in there yesterday with all the power tools going. So I can feel your pain.
