Are the doors and windows closed in hot weather?

In hot weather, if there is someone at home, I suggest you close the window after 10 am and draw all the curtains (preferably dark); If there is no one at home, close the window and close all the curtains (preferably dark) before going out in the morning, so as to keep the indoor temperature from rising (of course, it will definitely rise a little).
