Why does my baby's hair get wet when he sweats while sleeping?

I believe that mothers who often take care of children, as long as they are careful, will find that their babies often sweat on the back of their heads, especially now in the hot summer, this situation happens more frequently to babies. What is the reason for the baby's sweating? Why does the baby's hair get wet when he sweats while sleeping? Is it caused by other diseases? These problems often bother parents. Now let the experts give you a brief introduction.

Night sweats can be divided into physiological and pathological types. The incidence of physiological night sweats is especially high in children, which sometimes makes parents very nervous. Therefore, it is necessary to master how to distinguish between physiological and pathological night sweats.

(1) Physiological night sweats: In childhood, the skin is very tender, contains more water, has abundant capillaries, has active metabolism, and the autonomic nervous system regulation function is not yet perfect, so children are prone to sweating during activities. If children are too active before going to bed, the metabolism of various organs in the body will be active, which can increase the body's heat production. During sleep, the blood vessels in the skin will dilate, the sweat glands will secrete more, and the child will sweat profusely to help dissipate heat. Secondly, eating before going to bed can enhance gastrointestinal motility, increase gastric juice secretion, and increase sweat gland secretion, which can cause children to sweat more after falling asleep, especially within the first 2 hours of falling asleep. In addition, if the indoor temperature is too high, or the quilt is too thick, or electric blanket is used, it can cause profuse sweating during sleep.

(2) Pathological night sweats: Some children sweat mainly in the first half of the night after falling asleep, which is often caused by low blood calcium. Low calcium can easily increase the excitability of the sympathetic nerves, just like turning on the "faucet" of the sweat glands. This situation is particularly common in children with rickets. However, night sweats are not a unique symptom of rickets. A comprehensive analysis should be conducted based on the child's feeding conditions, outdoor activities, etc. Blood calcium, blood phosphorus and wrist bone X-rays should also be checked to determine whether the child has active rickets.

I believe that through the above introduction, moms and dads have a comprehensive understanding of the reasons why babies sweat and their hair gets wet when they sleep. In fact, baby sweating is what we commonly call night sweats, especially newborns. As long as they sleep, they will have this phenomenon. However, although this is a relatively common phenomenon, for the health of the baby, moms must find the cause to avoid other conditions.
