not possible for many people.Just buy a portable AC unit, you can pick one up for about £300
I just purchased a tower fan and it is really good even on the lowest setting so I’m hoping it will be helpful next week. I am worried about it as I don’t cope in the heat, I’ve been feeling nauseous for the past two weeks and it’s not fun. Also worried about the local wildlife and will be putting out lots of water and extra food as the ground is too hard for birds to dig for worms etc.
