The correct way is to take a bath 0.5-2 hours after meals. Some people think that taking a bath before going to bed will eliminate the fatigue of the day and make people fall asleep easily. It's actually wrong. It is best to take a bath 2 hours before going to bed. Sleep often comes after the body temperature drops. Taking a hot bath will raise the body temperature and delay the release of "sleep hormones" from the brain. O If you can only take a bath before going to bed in a day, you can use a wet towel to cold compress your forehead for 5 minutes after taking a shower, so that your body temperature can drop to normal level and you can fall asleep as soon as possible. In addition, sleeping with wet hair is easy to catch a cold and headache, and it can also cause hair loss, so pay attention to blow-drying your hair before going to bed! In addition, when blood pressure is too low, after drinking, after work, and when you have a fever, it is not appropriate to take a bath immediately. Drink a little warm water before bathing, and drink a cup of vegetable juice or fruit juice to pad your stomach before bathing. The washing contact temperature is 35-40℃. Bathing time 15-20 minutes, and the sanitary shower is 3-5 minutes. If the skin is not particularly oily, it is best to choose a neutral bath and fragrance to avoid hurting the skin. Wash your feet with hot water first, and then wash other places when the feet farthest from your heart are warm. Wash your hair before taking a shower.
