It is also  suggested to eat less raw and cold fruits and iced drinks to avoid diarrhea. To  prevent autumn dryness, you should drink enough water in time. Drinking a glass  of water with honey at night or eating a pear or persimmon can help relieve  dryness. After the hot days, the temperature at night is low, and you may even  feel cold. You should try to avoid staying up late at night. If you feel sleepy  during the day, you can continue the nap habit at noon. It is appropriate to  take a nap for half an hour to an hour.
