The room is just warm and not too hot, mom and dad are very comfortable, a look back at the baby, ah, the little one how to sleep drenched in sweat? Immediately startled out of a sweat: baby is sick, or calcium deficiency? Calcium knows that every time a little bit of the situation and have to be the back burner. Therefore, it is as eager as parents to know why the baby is sweating a lot? When should we go to the hospital? The baby sweats a lot is sick? First of all, parents need to understand the differences between the little ones and us adults. Babies are not well-developed neurologically and their cerebral cortex is poorly regulated by the vegetative nerves, so they are usually more prone to sweating than us adults in terms of their physiological development progress bar. Especially in the 0-3 years old babies, the skin water content is large, the skin surface microvascular distribution is more, the water evaporated by the skin is more. In addition, the regulation function itself is poor, metabolism still comes to be vigorous, and active, a little movement, or after the night sleep, sweat will come in a constant stream. However, although sweat, generally in the baby just fall asleep that will “surge”, because at this time the baby, the body is quiet, but the heat generated by the activities before bedtime has not been completely dissipated. So what to do? Sweating, in this way the body excess heat off. So parents startled, and then carefully observe the observation, generally baby just sleep the first one or two hours, forehead will still have a trickle of “sweat”, after not much sweating. In this case, of course, not sick.
