Why does my baby sweat on his head and neck when sleeping?

I believe that every baby is a treasure to the family, who holds the baby in their hands for fear of dropping it or melting it in their mouths. Parents are very concerned about the baby's sleep, diet, etc. Some babies will sweat on their heads and necks when they sleep. In this case, we must not take rash measures to avoid hurting the baby. Here is an introduction to why babies sweat on their heads and necks while sleeping.

Generally speaking, it is normal for babies to sweat a lot 1 to 2 hours after falling asleep, and it is not due to calcium deficiency. Generally speaking, babies sweat more than adults. Sweat is secreted by the sweat glands in the skin. Sweat glands are one of the important structures of the human skin for regulating body temperature. Children have active metabolism and a lot of activities, especially infants and young children, whose skin contains more water and has more microvessels on the surface of the skin, so more water evaporates from the skin. Besides, children have poor self-regulation ability for cold and heat, and they like to sweat even at night, which is normal.

Excessive secretion of sweat glands in babies is called hyperhidrosis. There are two main reasons for baby's excessive sweating: physiological excessive sweating and pathological excessive sweating.

Normal reasons

It is mostly normal for babies to sweat excessively, which is medically called physiological hyperhidrosis. For example, the hot summer weather causes children to sweat a lot; infants and young children sweat on their heads and necks when they just fall asleep, and the sweating decreases after they fall asleep; babies sweat a lot after playing, running and jumping, and generally

The situation is very good; in winter, the baby wears too many clothes, the quilt is too thick at night, and the indoor air-conditioning temperature is too high, which makes the baby overheat and sweat a lot. Some babies sweat only on the head and forehead, commonly known as "steamer head". This is also physiological sweating and parents do not need to worry.

Abnormal reasons

Babies sweat too much due to certain diseases, which manifests as sweating a lot when they are quiet or after falling asleep at night. The sweat can wet the pillow and clothes, which is called "pathological sweating." Such as active rickets in infants and young children, active tuberculosis in children, hypoglycemia in children, excessive dose of antipyretics and mental factors, such as excessive excitement and fear. Some babies have endocrine diseases (such as hyperthyroidism, etc.), which can also cause pathological sweating. In addition to excessive sweating, each disease also has many other disease manifestations. Parents need to take their babies to the hospital for further examinations.
