Is washing hands with cold water healthier than hot water? Of course, cold water is healthier than hot water. Can improve their tolerance. As you can see, many people who swim in winter are in good health. They won't catch a cold in summer or winter. Swimming in winter is not sick all year round, and people will be very healthy at once. It can stimulate people's nerves and improve their immunity. Personally, I wash my face with cold water all the year round and never use hot water. Good skin, good figure and comfortable feeling. It is uncomfortable to wash your face with hot water.
