In early childhood, due to vigorous metabolism and active children, some children are restless even after sleeping at night, and they can still sweat after falling asleep. The so-called physiological hyperhidrosis means that the child is well developed and healthy, and does not sweat during sleep caused by any disease. Parents are often used to determining the best ambient temperature of their children by their own subjective feelings, and like to cover their babies with more quilts. The development of children's brain nervous system is not perfect, and it is still in the period of growth and development. The metabolism of the body is very strong. Coupled with the stimulation of overheating, only by sweating can the body's heat be evaporated and the normal body temperature be adjusted. In addition, drinking milk or eating too much chocolate before going to bed can also lead to sweating. Some parents give their children milk before going to bed, and so on. After the child falls asleep, the body generates a lot of heat, mainly through sweating on the skin to dissipate heat. In addition, excessive room temperature or warmth is also the cause of children's sleep sweating, which belongs to physiological sweating.

Pathological sweating occurs in children's quiet state, such as rickets sweating, which is manifested as obvious sweating on children's heads half a night after falling asleep. Because the pillow is stimulated by sweat, the baby often shakes his head when sleeping and rubs against the pillow, which causes the hair on the pillow to become thinner and fall off, forming a typical annular alopecia on the pillow, which is medically called "pillow baldness" and is an early manifestation of infantile rickets. As long as vitamin D and calcium are supplemented in time, rickets can be controlled and sweating will stop.

Don't do strenuous exercise with your child before going to bed. Play soft music for your baby to enjoy, or tell him a story or two to calm his mood and help him fall asleep.
