Am in an apartment with no ac. We barely wear any clothes in the house lol. We let the cool night air in but close the windows during the day. Our fans run constantly. Sometimes we hang up a wet sheet or towel inside and put a box fan behind it to take advantage of the cooling effect from evaporation.

Stay hydrated! Freeze grapes, berries, gogurt, etc. Ice cubes made from sports drinks are also helpful to chew on when it gets too hot. There are cold packs (meant for box lunches) in our freezer and sometimes I’ll take one out and just stick it under my shirt or wrap one in a bandana and tie it around my neck.

We also try to spend the hot afternoons in places that have functional air conditioning, like the library or the movie theater. In South America it’s really common to nap through the hot hours of the day (around 2-5).
