预防着凉最好的办法就是预防孩子在冬季时过多出汗。由于孩子心脏的收缩能力有限,每次心脏搏动时达到四肢末梢的血液相对较少,造成孩子的手脚偏凉。因此,不要以孩子的手脚温度作为判断孩子的冷暖和穿着是否合适的尺度,应该以颈部温度作为标准,只要颈部温暖就说明孩子并不冷,不用再加衣服和被褥了。 The best way to prevent cold is to prevent your child from sweating excessively in winter. Due to the limited ability of the child’s heart to contract, the blood reaching the extremities of each heart beats relatively little, causing the child’s hands and feet to become colder. Therefore, do not use the child’s hands and feet temperature as a measure of the child’s well-being and wearing the right scale, the neck temperature should be as standard, as long as the neck is warm that the child is not cold, no more clothes and bedding.
