The child’s sweat glands and nervous system are not well developed, the plant nerve function is not stable, and in the growth period metabolism is strong, sweating is often more than adults, this is a normal physiological phenomenon, medical called physiological sweating. Children often sweat significantly on the head and neck when they fall asleep, but after they fall asleep, it can also be seen when the temperature rises, when they wear too many clothes and covers, when they are scared and frightened, etc. This is all physiological sweating, which can be reduced by using appropriate methods according to different reasons. If the child sweats a lot even after sleeping or in a quiet environment with appropriate insulation, it may be pathological sweating, which needs to be analyzed together with other symptoms and finally the cause of sweating is clear.
