Why does my 2-year-old baby sweat a lot when sleeping?

After the baby is born, parents will always pay attention to the child's growth. However, when the baby is two years old, he will sweat a lot when sleeping. At this time, parents will worry whether it is because the baby is weak and sweating, or the weather is too hot that causes the baby to sweat so much. As a result, they take measures such as supplementing the baby's nutrition or taking off the baby's clothes to deal with it, but it often backfires. So what is going on? Next, I will explain to you in detail why a two-year-old baby sweats a lot when sleeping.

It is common for babies to sweat during sleep, and it is not always a symptom of weakness or illness. Many parents believe that their children’s constant sweating is due to their weak constitution. In fact, a considerable number of children suffer from physiological hyperhidrosis. Physiological hyperhidrosis is more common in the head and neck, often occurring within half an hour after falling asleep, and sweating stops in about an hour.

Infants and young children have an active metabolism and are active and lively. Some of them cannot rest even after going to bed at night, so they may sweat on their heads after falling asleep. Parents are often accustomed to deciding the best environmental temperature for their children based on their own subjective feelings, and like to cover their babies with more blankets and keep them tightly covered. Because children's brain and nervous system are not yet fully developed and they are in the growth and development period, their body metabolism is very active. Coupled with the stimulation of overheating, they can only regulate normal body temperature by sweating to evaporate the heat in the body.

Some active children exercise a lot during the day and generate a lot of heat. The body is unable to dissipate the excess heat through sweating, so the heat accumulates in the baby's body, and the baby's body temperature can reach around 38°C at night. After the baby falls asleep, the heat generated decreases, the sensitivity of the sympathetic nerves decreases, and the body dissipates excess heat through sweating to maintain normal body temperature.

The weather is hot and stuffy in summer and the bedroom is poorly ventilated, so babies are more likely to sweat. This type of sweating is called "physiological sweating" in medicine. It usually occurs in the first half of the night when you just fall asleep, and the sweat gradually disappears after deep sleep. Parents do not need to worry too much about physiological sweating. This is just a physiological phenomenon during the baby's growth process. As the baby grows older, this phenomenon will gradually decrease.

The above is a detailed explanation of the reasons why two-year-old babies sweat a lot when sleeping. At this point, all parents should be relieved, because this situation is mostly physiological sweating of the baby. As long as you pay attention not to catch a cold, there will be no problem. Of course, what is introduced here is only most of the physiological sweating. In daily life, if the baby has a fever, it will also cause sweating. Therefore, everyone still needs to analyze specific problems specifically, so that the baby can grow up more healthily.
