We replaced our AC central unit a couple of years ago and went 1 ton up on it’s capacity. The upright fans cool it off enough out there where it is tolerable to sit out there for a bit. “What happens is that dilates the blood vessels in your skin, which helps the body dissipate heat, which allows your body to cool off, to fall asleep..Hydrate….Hydrate...Hydrate. I suggest if you do not have AC in your house… You can buy a small portable ( not window) AC and place it in a room and it helps a lot. I know my grandmother and Mother used a pressure cooker a lot in the summer and did not fire up the oven.
