Here in Paraguay is almost every day so damn hot. I just work outside at the morning, late evening and in the night. At the middle of the day i often have a short nap and i try to keep the house fresh - i don*t like
air conditioner (we don't need all this stuff to fill our planet with garbage)... So i close windows, doors, etc. to keep the "fresh" temperature from the night. And of course long cool showers to "suck out" all the heat from the body, especially before sleeping.
