A lot of babies are prone to sweating and pillow baldness at night, and parents are anxious to know if this is a symptom of calcium deficiency in their children. In fact, sweating and pillow baldness is not necessarily a calcium deficiency, take a look at it together! Many mothers will encounter such a situation when caring for their babies: sleeping at night, not to my baby cover things, a touch of her head is full of sweat. And I don’t even feel very hot. Is sweating a lot because of calcium deficiency? There are five situations in which children are physiologically sweaty It is common for small children to sweat during sleep, not all of which are symptoms of weakness or physical illness. Many parents believe that their children are weak and therefore sweating constantly. In fact, a significant number of children have physiological hyperhidrosis. Physiological hyperhidrosis refers to sweating during sleep when the child is well developed and healthy, without any disease. Physiological hyperhidrosis is usually found on the head and neck, and usually occurs in the first half of the night when the child first goes to sleep, and the sweating subsides after a deep sleep. It is often caused by the following five reasons: 1, infancy and early childhood because of the high metabolism, coupled with children active and active, some even after going to bed at night can not be restful, so the head can also sweat after going to sleep. 2, parents are often accustomed to their own subjective feelings to determine the best environmental temperature for children, like to give the baby more covered, covered tightly. Children because the neurological development of the brain is not yet perfect, and in the period of growth and development, the metabolism of the body is very vigorous, coupled with the stimulation of overheating, only through sweating, to evaporate the body’s heat to regulate the normal body temperature. 3, some active children, a lot of exercise during the day, more heat generated, the body does not have the ability to disperse the excess heat through sweating, heat accumulation in the baby’s body, the baby’s body temperature at night up to about 38 ℃. After the baby falls asleep, the heat generated is reduced and the sympathetic nerve sensitivity is weakened, so the body emits excess heat through sweating to maintain the normal body temperature. 4, in addition, children drinking milk, cream of wheat or eating chocolate before going to sleep will also cause sweating. Some parents give their children milk, cream of wheat, etc. before they go to sleep, and the children’s bodies produce a lot of heat after they fall asleep, mainly through skin sweating to dissipate heat. 5, the summer weather is hot and muggy, the bedroom ventilation is poor, the baby is more likely to sweat. For physiological sweating, parents need not worry too much, this is just a physiological phenomenon in the growth process of the baby, as the baby grows older, this phenomenon will gradually reduce.
