”Doctor, my baby’s pillow will be wet when he sleeps”, “My son usually sweats a lot when he moves, what should I do?”. . This is a problem that we usually encounter in the clinic, how to solve this problem? So first we must know why children sweat? Is sweating good or not? Is it normal to not sweat at all? Sweating includes dominant sweating and non-dominant sweating. If the temperature exceeds 30 degrees Celsius, people start to sweat, and the active sweat glands increase, sweating is obvious, and the feeling of sweating is called dominant sweating. When nervousness, fear or eating irritating food, small sweat gland secretion activity obviously increased, sweating increased, also known as dominant sweating, through sweat volatilization can take away heat and play a role in regulating body temperature. The sweating is usually less than the sweating of ordinary people every day, and is generally not felt subjectively, which is called non-dominant sweating in medical terms. Both of these sweating patterns are normal, and they both regulate the distribution of heat, thus keeping the body temperature constant. The reason why a healthy person must have sweating, and this is even more important for children, there is a saying that “in order for a child to be safe, the body sweat often does not dry”, this is a certain scientific basis. So that children usually have to sweat properly, not sweat is not normal. But compared to adults, children sweat more. This is due to the rapid growth and development of children, metabolism is more vigorous than adults, the heat generated and metabolic products are relatively more. Children belong to the pure Yang body, the body is delicate and soft, muscles and skin are very weak, also more likely to sweat. At the same time, children’s plant nerves are not well developed, when sleeping, the sympathetic nerves in charge of sweat glands will lose control of the brain and momentarily excited, sweating phenomenon, if there are no other abnormalities, this is completely normal. However, if the child is usually in poor health, thin and weak, with irritability, crying, poor sleep or occipital baldness, square cranium, funnel chest, tuberculosis, etc. is pathological sweating, you must go to the hospital for examination. The main clinical causes of excessive sweating in children are zinc and calcium deficiency, as well as deficient sweating due to physical weakness. Therefore, trace elements and bone alkaline phosphatase are mandatory tests, and if possible, a full set of immune tests can be done as well. In Chinese medicine, sweating is divided into spontaneous sweating and night sweating, both of which are pathological phenomena. Self-sweating refers to those who sweat naturally without using sweating medicine or excluding other stimulating factors such as hot weather, thick clothing, or strenuous activities, but who move slightly around the clock. Such children mostly have Yang Qi that is not fixed, and the fluids are dipping out. Night sweats are also known as “bed sweats”, sweating while sleeping and stopping immediately after waking up. The reason for the night sweats is usually due to Yin deficiency and heat disturbance, and the heart fluids cannot be collected. The actual sweating should eat more foods that have the effect of strengthening the spleen, such as japonica rice, coic rice, etc. Night sweats should eat more foods that have the effect of nourishing yin and generating fluid, such as millet, wheat flour and a variety of mixed grains and soy products, milk, eggs, lean meat, fish, etc. Fruits and vegetables should also be eaten more often, especially to eat more apples, sugar cane, bananas, grapes, hawthorn, watermelon and other fruits that contain more vitamins. Meanwhile, yam, lentils, lotus seeds, dates, etc., these can both strengthen the spleen and benefit the qi, and can also harmonize the stomach, is also a good diet regimen. For children with low resistance caused by excessive sweating, it is recommended that you can drink water with astragalus.
