The body temperature is controlled by the hypothalamus thermoregulation center. It is like a remote control for our body temperature. Under normal circumstances, it sets the body temperature at about 37°C. When sick, the remote control raises the body temperature and we will have a fever. Up.

Once the body temperature regulation center raises the set temperature, the brain will send a signal to the body to make people feel cold, and then through the regulation of nerves and hormones, the body will chill to produce heat, and at the same time reduce heat dissipation by constricting the blood vessels of the skin. So when the fever starts, there will be chills and cold hands and feet.

When the body temperature reaches the set temperature, we won't feel cold anymore. At this time, the chills are reduced, the blood vessels of the skin do not need to shrink, and the heat production and heat dissipation will maintain a balance.

After fever for a period of time, such as control of the disease or taking antipyretics, the body temperature regulation center may adjust the body temperature back to about 37°C. If the actual temperature of the human body is higher than the set temperature, it will feel hot, and the brain will send a signal to the body. , Stop the shivering, and at the same time, by expanding the blood vessels of the skin and starting sweating, these heat dissipation methods can reduce heat production and increase heat dissipation. As a result, the body temperature will return to normal.

How to wear clothes for children with fever

It is easy to know the answer if you remember that coping with fever is to "make the child as uncomfortable as possible" principle.

When the child feels cold, wear a cover until he does not feel cold. This is actually the process of helping the child's body temperature reach the set temperature of the thermoregulation center as soon as possible. If the parents don't wear a cover for him, he will use more chills to produce heat and consume more physical energy. At this time, cooling the child physically is counterproductive
.
When the child feels hot, it means that the body temperature regulation center has lowered the set temperature. You should reduce the clothing and increase the heat dissipation to help the child cool down. Without reducing the clothing and quilt, the body temperature will not return to normal if the heat cannot be dissipated.

In the process of fever, the body temperature will go through uphill, flat road, and downhill stages, and this process may be repeated. In the uphill stage, the child will feel cold, and then wear a blanket; in the downhill stage, the child will feel hot and sweat, so reduce the quilt.

Remember to wear it when it is cold, and take it off when it is hot, how come your child feels comfortable.

Talking older children are easy to care for. But for a baby who can't talk, parents need to be more careful when taking care of fever, especially when putting on a cover. It is necessary to observe whether the child has chills and whether the hands and feet are cold. If the child's body temperature has reached the central set point and continues to wear the cover, it may not be able to dissipate heat, resulting in heatstroke, muggy syndrome and other problems.

Why do you feel very hot when you have a fever, and then just sweat

Feeling that heat is when the body thermoregulation center has lowered the set temperature, and then the antipyretic mechanisms such as sweating will be activated. Sweating is a way to reduce fever, and the final feeling is just sweating all over. In fact, sweating is only when you get better, not sweating to make you heal.

Why do I sweat after taking antipyretics

Antipyretic drugs can lower the temperature set by the thermoregulatory center. After the drug takes effect, if the actual body temperature of the human body is higher than the temperature set by the thermoregulatory center, you will feel hot, and then activate the heat dissipation mechanism including sweating, and the result is eating After sweating out of the antipyretic medicine, I found that my body temperature was almost back to normal. Antipyretic drugs cause sweating by lowering the set temperature of the thermoregulatory center.
