Use water to cool the place down
In summer, water is your best friend. To avoid getting overheated, put a container of water and ice in front of a fan. So, the cool water that evaporates will spread around the entire place.
If you don’t have a fan, you can put the water container on the windowsill and the hot air from the street will cool down.
that's what i was going to say go to Walmart spend 100 bucks and get an ac its like 20 dollar a month to not suffer and for your pets that are literally wearing a fur coat to not suffer.
