It's very hot in summer. How to cool down?
You can also wipe the mat with toilet water. The specific operation is to pour a pot of cold water first, then add a proper amount of toilet water, and then wipe the mat with a rag, but it should be noted that the rag must be wrung out before wiping, so that the mat will become very cold!
Put the wet towel in the refrigerator to cool down. Of course, if you use this method, the damage to the towel will be very great, so you should choose a cheap towel, put it in water, wring it out properly, and then put it in the freezer in the refrigerator, but be careful not to take too long, about an hour or two, and then wipe your body with a cold towel, which will also have a cooling effect!
You can also install thermal insulation curtains to block heat from entering the room. If you go out in the morning, you should pay attention to closing the windows first, then closing the thermal insulation curtains, and then opening the curtains when you come back from work at night, so that the sun can't shine in all day and the room will be very cool.
