1. Method 1: Be sure to keep warm. In summer, you must wear clothes with sleeves, pants and socks in an air-conditioned room. You'd better not walk barefoot at home. Usually you can't sit on the cold ground, or on the stone floor, or on an iron stool. You must not put your arms and feet outside the quilt when you sleep at night, and you'd better wear cotton socks when you sleep in summer.
2. Method 2: Don't eat cold things, fish and shrimp, and don't often eat spicy, greasy and easy-to-get-angry food. Don't eat common foods that can make people diarrhea and comb liver qi, such as radish, hawthorn, betel nut, coriander, perilla leaf, mint, kumquat and so on.
3. Method 3: Wash your face with warm water before going to bed every night, and then soak your feet with warm water. It's good to know that people who soak up sweat a little. After soaking their feet, you can rub your ears, comb your hair and tonify your kidney. Pay attention to going to bed early, don't stay up late, and keep the energy of the day.
