If AC isnt an option, the way Ive gotten through summers without is opening one window on one side of the building, then another one on the opposite side. Then point a box fan facing outward of one window, and do your best to seal the gaps with some cardboard or whatever you have. This will create negative pressure in the building, drawing in a bunch of air from the opposite window.
it's the same reason a breezy summer day feels cooler, the air is still cooler than your body temp and draws away heat better than sitting in still air, plus its more evaporation if you're sweating hot. also indoors without AC during summer is an insulated oven.
would be nice with a test for a sealed fan like I described. the problem with that setup is that the negative pressure will try to pull from both windows, competing with the fan trying to blow out and not getting as much flow
air will be blown over your body either way, all you're changing is the direction the air is coming from. blowing from the ceiling means blowing hotter risen air
People from the "hotter" regions, how do you deal with the heat?
I am from Eastern Europe and this is the hottest summer on my memory. For at least 3 consecutive years the heat is breaking all records....
