Cold sweats in baby’s sleep at night need to be analyzed from two angles: first, the problem exists that the baby is prone to sweating at night. Sweating should consider whether the intake of vitamin D and calcium intake is appropriate, when the intake of vitamin D is not enough, calcium malabsorption is easy to sweat, especially in the second half of the night sweating will be more obvious; secondly, if the covers are too thick or some babies sleep in clothes while covered with a thicker blanket, is easy to sweat. Second, the baby sweats, but sweat or cold sweat, this time to consider should be more sweat, when not in time to dry the skin sweat processing, this time sweat in the process of evaporation took away a lot of heat from the body surface, so that the body surface temperature is low, the same reason, sweat touch is also low temperature, that is, the performance of cold sweat. So when there is a cold sweat at night in bed, first from these two angles to observe and adjust. To ensure a reasonable intake of vitamin D, ensure milk intake to provide adequate calcium, if necessary, appropriate calcium supplements; at the same time, pay attention to adjust the thickness of the quilt; if there is sweating, timely sweat drying treatment.
