Modern parents are very concerned about their children's health. In the cold winter, many parents are afraid that their children will catch cold and are used to preparing hot water for their children to wash. Their original intention is for the good of their children.

However, from the perspective of health care, it is best for teenagers to develop the habit of washing their faces with cold water in winter, which is not only conducive to promoting the healthy development of teenagers' tissues, organs and nervous system, but also to enhancing their adaptability to cold and improving their immunity and resistance.

Cold water stimulation can enhance cold tolerance. Teenagers are in a period of vigorous development of various physiological functions and are very sensitive to the cold and hot changes in the outside world. Wash your face with cold water in winter to exercise your ability to cope with the cold. When your face comes into contact with cold water, your self-instinct will mobilize all the energy to cope with this temperature change, and all the tissues and organs of your body will take active actions to accelerate blood circulation, improve the excitement of your body and generate heat to fight against the cold. So washing your face with cold water is a small gesture, but it is an exercise for your body.

Washing your face with cold water helps to reduce illness. In cold winter, the temperature difference between indoor and outdoor is large. Teenagers will open their pores in hot places and suddenly go outside in the cold. If the pores do not adapt to this change and cannot be closed in time, the cold will invade the human body, and diseases such as colds and respiratory infections are prone to occur.

Washing your face with cold water can exercise your body's rapid response to cold and heat, help you adapt to the rapid changes between cold and heat, and avoid diseases caused by cold. In addition, washing your face with cold water can also exercise your blood vessels and nervous system, which has a good preventive effect on headaches and gastrointestinal diseases.
