It is best to exercise in the early morning or evening, and it is not advisable to do excessive strenuous exercise. Too much sweating will not only hurt the yin, but also hurt the yang.

If you can't sleep in the hot weather, you can open the window to ventilate after getting up in the morning and close the curtains before going to work. Turn on the air conditioner (about 27 degrees) after work at night, and open the door of the room to ventilate each other, so as to keep the temperature difference between the rooms balanced and create a cool environment, which is naturally conducive to falling asleep.
