It's getting hot. Children over two years old sweat a lot at night and their hair is wet. What happened?

Generally speaking, babies are older than adults, love sweating.

Sweat is secreted by sweat glands of the skin, which is one of the important structures of human skin to regulate body temperature. In childhood, due to vigorous metabolism and high activity, especially in infants and young children, the skin contains a lot of water and there are many capillaries on the skin surface, so a lot of water evaporates from the skin. Besides, it is normal for children to have poor self-regulation ability in cold and heat, and even in the evening, they are love sweating.

The baby is particularly sweaty, is it normal or abnormal?

Any baby with excessive secretion of sweat glands is called hyperhidrosis. There are two main reasons for baby hyperhidrosis: physiological hyperhidrosis and pathological hyperhidrosis.

Normal cause

Baby hyperhidrosis is mostly normal, which is medically called physiological hyperhidrosis. For example, the hot climate in summer causes children to sweat; When infants and young children just fall asleep, they sweat on their heads and necks, and sweat decreases after falling asleep. The baby sweats a lot after playing games and running, and the general situation is very good; The baby wears too many clothes in winter, the quilt is too thick at night, the indoor air conditioning temperature is too high, and the baby is overheated and sweaty. Some babies only sweat on the head and forehead, commonly known as "steamer head", which is also physiological sweating, so parents don't have to worry.

Abnormal cause

Because of some diseases, the baby sweats too much, which is manifested by sweating a lot when he is quiet or asleep at night. Sweating can wet pillows and clothes, which is called "pathological sweating". Such as children's active rickets, children's active tuberculosis, children's hypoglycemia, excessive use of antipyretics and mental factors such as excessive excitement and fear. Some babies have endocrine diseases (such as hyperthyroidism). ), it can also cause pathological sweating. Besides sweating, every disease has many other symptoms. Parents need to take their baby to the hospital for further examination.
