Baby sweats a lot when sleeping

The baby's sleep conditions have a great impact on growth and development, because if the baby gets enough sleep, the body will have more time to grow. However, many babies will show abnormal physical manifestations during sleep. For example, excessive sweating is a common problem that will cause babies to toss and turn during sleep, affecting their physical development. Let’s take a look at why babies sweat 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. The so-called physiological hyperhidrosis refers to sweating during sleep when the child is well-developed, healthy, and has no disease. 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.

In addition, drinking milk, malted milk or eating chocolate before going to bed can also cause sweating in children. Some parents give their children milk, malted milk, etc. before they go to sleep. After the child falls asleep, the body produces a large amount of heat, which is mainly dissipated through sweating through the skin. In addition, too high room temperature or excessive warmth can also cause children to sweat while sleeping, which are all physiological sweating.
