How did people get through without air conditioning before?

Set up tents outside in summer and sit around to keep warm in winter. This is how everyone gets through the days without air conditioning.

My mother told me that they didn't have air conditioning at home when they were young, and it was very hot in summer, in order to lower their body temperature. The old man just holds a fan. Although the wind is light, it can at least make his body feel a little comfortable. Most young people jumped into the river to take a bath. Generally speaking, after a cold shower, they can make themselves comfortable for an afternoon. The night is the hardest. Not only is the weather hot, but there are also many mosquitoes. Staying indoors is particularly uncomfortable, so everyone will set up tents in their own yards to enjoy the cool.

Winter is relatively more tolerable than summer. In the past, the countryside cooked by burning wood. When it's time to cook, children scramble to make a fire, because this MengMeng keeps them warm. In fact, after dinner, most people will go outside in groups of three or five, raise bonfires and sit around baking sweet potatoes, which will make them feel particularly warm.
