If an infant has a hot head, it is mainly due to the following two conditions: firstly, it is due to the physiological characteristics of children, because the circulation of blood and Qi in infants is very smooth, and the metabolic rate of infants is relatively fast, for example, the heartbeat and breathing times of children are significantly faster than those of adults. In this case, due to the rich blood and blood vessels in the head of the child, the temperature of the head is relatively hot, and it is within the normal range to take the temperature of the child, but due to the rich blood circulation in the head, the head feels hot. In this case, the child’s mental state and feeding condition are relatively good and no special treatment is needed. Secondly, head fever is caused by fever in infants. In this case, children not only have head fever, but also have generalized fever, and the axillary temperature is often higher than 37.5℃.
