This sentence has two meanings. The first thing is not to wash your hair too often, but you can comb your hair often. Because the scalp has many pores, it is easy to be attacked by colds, especially when it is windy, which is not good for health. Comb your hair often, and you can massage it to the nervous system of the brain and the acupoints of the head, which can relieve fatigue, promote scalp health and stimulate hair softness. However, our faces can be cleaned often. From the perspective of health care, the essence of our internal organs is concentrated on the face. We can massage our face more in the process of washing our face, which can enhance blood circulation.

The second layer means that you can't take a bath often, because every time you take a bath, your pores will open and the energy and blood contained in your body will be emitted, so it is best to take a bath every 3-4 days. Moreover, there are also many acupoints on the body, which can be massaged by hand, similar to dry cleaning, which is also conducive to enhancing the blood circulation of our body and achieving the purpose of health preservation. Finally, massage your face after taking a shower every time, which can make the blood in your body smooth.

Third, there are many taboos in bathing. First, it is not advisable to take a bath in a hungry state, because it will make the body weaker. The second is to take a bath in the secret room to avoid cold invasion. The third is to dress quickly and keep warm after taking a shower, especially if the abdomen can't see the wind, just like covering the stomach with a quilt in summer. Once the stomach catches cold, it will cause all kinds of gastrointestinal discomfort or cause a cold. Some people may ignore these points, so taking a bath often will increase the chance of catching a cold.

In addition to the above, there is a little common sense, that is, you can rinse your mouth with cold water and prevent some dental problems. If you get used to it, you won't feel cold in winter, and it won't hurt so much when your teeth fall out. Of course, it is also possible to rinse your mouth with warm water, but it can only remove dirt. The above precautions are put forward by some health experts and drawn from some experiences of people who have experienced them.
