Consistantly 100 degrees daily

My last house had a pool. It was great to work on the cars and then jump in the pool for a quickie cool-off.
Here now, I have a bigger place and a shop.....but no pool.
I sweat and drip when it gets hot. Forearms and calves with streams of sweat....OOOf.
Being in construction, I'm used to it. It has been a problem when painting cars though. Sweat on wet paint is trouble!
