Fever is supposed to be the most common symptom in children, but whenever a child has a fever, mom and dad are still anxious. They want to do something for their children, hoping that they will get better faster. However, if parents do not know about fever, they will make the opposite effort and cause the condition to worsen. For example, when a child has a fever, nine out of ten parents will think of using a cold towel to put on the child to lower the temperature. The author tells you that this practice is not necessarily right. When to use cold towels, when to use hot towels, but there are a lot of things to look at. First, let’s talk about why the child will “burn” up. 1, fever is the “external enemy” and the “human immune system” the results of the battle. The human body temperature is regulated by the central nervous system. 2, when the child is sick, it may be a viral infection, bacterial infection or mycoplasma infection, etc., the foreign enemy, the body’s immune system to meet the march. 3, the enemy is like water and fire, it is not like a war between countries, there is no room for negotiation. So when the two sides meet is a white-hot battle of life and death, the human body temperature will rise. 4.When the central nervous system gives the order, the body temperature will rise? Of course not, the central nervous system then ordered, there must be subordinates to carry out the order to do. Parents pay attention, this time the child’s body temperature is in a “rising period”. 5, when the child has a fever, will be cold chills, some parents will be more careful, will find the child’s body goose bumps are out, in fact, this time his body temperature is in the rising period. Second, the child’s body temperature rising period to use hot towels 1, why some parents to the child’s body temperature, will find that the child is still 38 ℃, a dozen or 20 minutes later, it became 39 ℃? The reason is here, because the child is in the “temperature rise period”. 2, then this time, parents must not use cold towels to apply. The body surface would have needed heat, you then use a cold towel to compete for heat, which only allows the central nervous system to give more “severe” orders, the child’s body temperature will certainly rise even higher. 3, so the child is in the fever of the temperature rise period, must use a warm towel, to the child wipe the belly fossa, armpits, leg fossa these large blood vessels distribution area. In this way, the child’s body temperature may still rise, but not too high at once and appear high fever, or even convulsions, seizures. When the child’s temperature is in a stable period, for example, the fever stays at 39℃ for a short period of time, this means that the release of the central medium of fever is finished or has come to an end. 2, at this time, parents can use a cold towel or ice pack to the child’s head, or use a cold towel to wipe the armpits, neck, leg fossa and other large blood vessel distribution areas. This can help the child to cool down the fever, but also to avoid the child’s body temperature to rise again. 3, the other is the period of decreasing body temperature, that is, the body slowly dissipate heat period can use cold towels, this period is characterized by the predominance of heat dissipation process, the role of thermogenic sources in the body gradually disappeared or weakened, heat production began to reduce. Children’s body surface skin blood vessels began to expand, this time will be a lot of sweating. 4, just like when we had a cold and fever as a child, elders would say “sleep under the covers, sweat and you’ll be fine”, that’s the reason, when sweating, most cases indicate that the fever is in remission. This time use a cold towel to help dissipate heat and make the fever go down a little faster.
