What causes calf sweating?

Some people may be surprised to see sweat in their calves, because they feel that they sweat easily and worry that there is something wrong with their body. It is actually normal for your calves to sweat when the weather is hot, because the human body has sweat glands all over the body.

Generally speaking, babies sweat more than adults.

Sweat is secreted by the sweat glands in the skin, which are one of the important structures of the human skin for regulating body temperature. Children have active metabolism and a lot of activity, 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.

My baby sweats a lot, is this normal or abnormal?

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 weather in summer causes children to sweat excessively; infants and young children sweat on their heads and necks when they just fall asleep, but the sweat decreases after they fall asleep; babies sweat a lot after playing, running and jumping, but are generally in good condition; in winter, babies wear too many clothes, the quilts are too thick at night, and the indoor air-conditioning temperature is too high, causing babies to 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 baby to the hospital for further examinations.
