Why does my child's head sweat a lot?

Every child grows up under the careful care and attention of his parents. Many situations will arise in the process of growing up. Parents are very worried that their children will get sick or feel unwell. Every symptom of the child will affect the parents. As the child grows, his resistance will increase day by day. Some children often sweat on their heads, which makes their parents feel very worried. They don’t know what causes it. So, what is going on with children’s heads sweating frequently? Let’s find out together.

Sweating is a kind of nerve reflex in the body. Because babies are in the stage of growth and development, their physiological metabolism is vigorous and the regulatory function of the nervous system is not very sound, so they sweat a lot. This is medically called physiological hyperhidrosis. Babies with this kind of physiological hyperhidrosis will sweat more obviously in the following situations, such as in summer, when the baby wears too many or too tight clothes, when the baby is active, when eating hot food, or when the baby is nervous or scared.

In fact, night sweats in children are not necessarily pathological. Most of them are physiological. Because children's skin contains more moisture, has abundant capillaries, has an active metabolism, and their autonomic nervous system regulation function is not yet fully developed, they are prone to sweating when they are active. If children are too active before going to bed, it can increase the body's heat production, or shortly after eating, gastrointestinal motility increases, gastric juice secretion increases, and sweat gland secretion also increases accordingly. These can cause children to sweat more after sleeping, especially within 2 hours after sweating. In fact, sweating is a normal physiological phenomenon of the human body. Sweat can take away excess heat and some metabolic products such as uric acid and fatty acids in the body. Because children grow and develop rapidly, their metabolism is more vigorous than that of adults, and they generate relatively more heat and metabolic products. At the same time, children's autonomic nervous system is not fully developed. When they fall asleep, the sympathetic nerves in charge of the sweat glands will be temporarily excited due to the loss of control by the brain, resulting in excessive sweating. This is completely normal. As long as the child has no other symptoms, such as irritability, crying, easy waking, etc., there is no need to worry about him. This type of sweating often occurs within half an hour after falling asleep, and is mainly on the forehead. It usually stops slowly within 2 hours after falling asleep and gradually disappears with age. Some people call it physiological hyperhidrosis.

However, if the child is usually weak and sweats profusely when falling asleep at night, as if he is being drenched in water, or even sweats all night long, wetting the pillow and clothes, and is accompanied by symptoms such as irritability, crying, and weight loss, then it is pathological hyperhidrosis.

The above is all about why children often sweat on their heads. Every one of us sweats. Sweating is a physiological characteristic. Some parents dress their children in more clothes to keep them warm, and babies will also sweat excessively. Therefore, when this happens, parents don’t have to worry. As the child grows, the sweating will gradually improve.
