Children sweat easily when they just fall asleep.

Sweating is a very normal phenomenon. Normally, sweating can happen to anyone, including children. However, there are many reasons for children to sweat, both physiological and pathological. Parents need to learn to distinguish them. Some babies sweat just after falling asleep. Most parents are often very worried when their babies have this problem.

Why does the child sweat easily when just falling asleep?

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.

What does physiological sweating mean for children?

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.

Reasons why babies sweat a lot when sleeping

Because children grow and develop rapidly, their metabolism is more vigorous than that of adults, and they generate relatively more heat and metabolic products. At the same time, children's autonomic nervous system is not fully developed. When they fall asleep, the sympathetic nerves in charge of the sweat glands will be temporarily excited due to the loss of control by the brain, resulting in excessive sweating. This is completely normal. As long as the child has no other symptoms, such as irritability, crying, easy waking, etc., there is no need to worry about him. This type of sweating often occurs within half an hour after falling asleep, and is mainly on the forehead. It usually stops slowly within 2 hours after falling asleep and gradually disappears with age. Some people call it physiological hyperhidrosis.

However, if the child is usually weak and sweats profusely when falling asleep at night, as if he is being drenched in water, or even sweats all night long, wetting the pillow and clothes, and is accompanied by symptoms such as irritability, crying, and weight loss, then it is pathological hyperhidrosis. A common cause is vitamin D deficiency rickets. In addition to excessive sweating at night, there are also symptoms such as irritability, restless sleep, easy awakening, square head, baldness on the occipital bone, and pigeon chest. Under the guidance of a doctor, you can supplement vitamin D and calcium in appropriate amounts. When eating, you should also pay attention to eating more foods rich in calcium, such as fish, shrimp skin, etc. With active treatment, the symptoms of excessive sweating can generally be relieved.
