Why are children prone to fever? Can a fever really burn out the brain?

Children are prone to fever and colds at the turn of the seasons if their parents do not take proper care of them. If you don't see it for a long time, you will definitely burn out your brain.

We will find such a phenomenon, when the season changes, many children and the elderly are prone to colds, because the immune system of this group of people is relatively low. Newborn babies can also get immune proteins from breast milk, and after weaning, the immune proteins will gradually disappear, coupled with the imperfect development of their own immune system. Then it is easy to be invaded by viruses, and this cold is often recurring.

Some children will lack some trace elements, some are deficient in calcium, some are anemia, maybe the child is a picky eater, and the nutritional intake is not balanced, so this phenomenon will occur. There are also some grandparents who are bringing, and they wear a lot for their children all day long, and they are always afraid that the child will be cold, and once this dress is taken off, it is easy to cause a cold. Some children are reluctant to drink water, have less metabolism, and have more natural problems.

I don't think a normal fever will burn out the brain. However, if the temperature of the fever exceeds the limit of the person's tolerance and lasts for a relatively long time, then there is still a possibility of brain damage. There are also some viral infections that can also affect brain development when there is a fever.

My son once had a high fever, and after giving him antipyretics, the fever still didn't go away. Because it was the first time I was a mother, I didn't understand a lot of things, and I covered him with a quilt very firmly, but what I didn't expect was that the temperature not only did not drop, but there were convulsions, and later, I went to the hospital to see. After hanging the saline for a few days, the temperature dropped and the child developed a rash, which the doctor said was a toddler emergency.

I think that once a child has a fever, it is important to be vigilant. There is a child in our village, who is more than 6 years old, and has had a high fever for several days, but the child's parents have not paid attention to it, so they did not go to the hospital to see him, and then left.

Children's immune system is not fully developed, and the immunity is lower than that of adults, so it is easy to cause fever when encountering a change of seasons or alternating hot and cold, and if the fever exceeds the maximum extent that the human body can present, and if it is not processed for a long time, some viruses will affect the brain cells, resulting in various problems in the development process.

Because the child's body has not grown well in all aspects, and the resistance is low. Fever above 40 degrees can burn the brain, usually children have a fever generally not so high, more than the degree to drink antipyretics, will also be sent to the hospital quickly, so will not let the child's brain burn out.

Children are prone to fever, but also because children are relatively small, their resistance is relatively weak, and they are easily disturbed by some bacteria and viruses.

1. A child's high fever will burn out the brain, and many parents are convinced of this. Experts say this is a misconception that fever itself does not cause damage to the brain, which is often caused by other diseases, such as meningitis, which damage brain nerve cells. It is extremely unscientific to judge whether the body temperature will cause damage to the brain, but should be determined comprehensively according to the child's age, physical and mental condition at the time of fever.

2. There are usually two types of fever, one is the active fever of the body, and the other is the passive fever of the body.

Active fever is the most common form of fever in children, such as when children are infected with inflammation (the most common is a cold), when the purpose of active fever is to defeat inflammation. The hypothalamus of the human brain controls and regulates body temperature, and the body temperature generally does not exceed when active fever occurs.

Passive fever is caused by heat stroke, poisoning, traumatic brain injury, tumors and other external reasons that cause problems in the regulatory center of the brain, and the temperature is easy to reach more than 40 at this time. In fact, the pathological basis of brain damage is the denaturation of proteins around the brain, and only a high temperature of 50 or 60 can denature the proteins and form brain damage, which is impossible for the average fever of children to reach this temperature in reality.

3 In real life, we find that often as soon as a child has a fever, parents are very anxious, and they do everything possible to reduce their child's body temperature quickly, and some even worry that the child will burn out his brain. In fact, fever burns the bad brain before the sail limbs, many times it is not simply caused by the fever itself, the vast majority of pediatric infections are ordinary endogenous ** infection, the fever it causes, the body temperature rarely exceeds 41 degrees Celsius, this kind of fever will not cause damage to brain cells, resulting in brain burning.

As for the possible damage to the brain, it is more common in encephalitis, meningitis, sepsis and other conditions; Or the ultra-high fever of heat stroke (body temperature is often close to 42 degrees Celsius), which causes the brain cell proteins to irreversibly become hungry and dry.

4 Although fever is not the same as brain injury, it does not mean that fever does not need to be paid attention to, because persistent high fever can easily cause repeated febrile convulsions, which has a greater impact on children.

1. When the body temperature is between degrees Celsius, it is low fever, 38 to 39 degrees Celsius is moderate fever, more than 39 degrees Celsius is high fever, and more than 41 degrees Celsius is super high fever.

2. Generally speaking, when the body temperature does not exceed 38 degrees Celsius, there is no need to rush to reduce fever, especially before a clear diagnosis, blind use of antipyretics may cover up the condition and interfere with the diagnosis; When the body temperature reaches above Celsius, consider reducing fever under the guidance of a pediatrician.

3. If the body temperature is below Celsius, it is best to use physical cooling. If you drink more water, let it wear as little clothes as possible, so that it can radiate heat through conduction, convection, and radiation with air, so as to achieve the purpose of cooling. Cool down with a warm water scrub bath.

4. When the axillary temperature is higher than Celsius, antipyretic drugs can be selected under the guidance of doctors.

Does fever "burn out" the brain Fever is a common symptom of illness in little Si Min's children.

When a child has a fever, many parents are afraid of "burning out" the child's brain and affecting the child's intelligence, so they are often eager to give the child antipyretics. So, does a fever "burn out" a child's brain?

To answer this question, let's first understand the effects of fever on the human body.

The effects of fever on the human body have both positive and negative sides. Fever is an important physiological defense response of the human body against disease. In case of fever, the number of white blood cells in the blood, the production of antibodies is active, the detoxification function of the liver is enhanced, and the metabolism of substances is accelerated, which can improve the patient's resistance; Fever can inhibit the growth and reproduction of certain pathogenic microorganisms in the body.

These changes are conducive to the elimination of the most advanced hormone and the improvement of the disease.

On the other hand, fever, especially high fever, can also bring some harm to the body. For example, fever increases the excitability of the nervous system, especially when the fever is high (40 41), and the patient may experience irritability, slurring, and hallucinations. Some patients have headaches.

In children, because the central nervous system is not yet mature, a high fever is more likely to cause convulsions (febrile seizures). Fever can make the heart beat faster, the average adult body temperature rises 1, the heart rate increases by 15 times per minute, children can increase more, the heart rate can be too fast can increase the heart burden of heart disease or anemia patients, and even cause heart failure. In addition, when you have a fever, you will consume a lot of your own substances and energy, which are not good for the human body.

It can be seen that in addition to the possibility of causing convulsions in children, fever will not "burn out" the child's brain and affect the child's intelligence. When a child has a high fever and convulsions, if it is handled properly, it will not cause brain damage to the child, and only a small number of children have hypoxia due to convulsions for too long, which may cause brain damage and affect intelligence in the future. In addition, because there are many causes of fever, some diseases themselves may invade the brain, such as encephalitis, meningitis, etc., and directly cause brain lesions.

But this is not due to the excessive fever that "burns out" the brain, but because the brain is affected by the disease, so the fever does not go away.

Therefore, for children with general fever, it is not advisable to rush to relieve fever, and sufficient nutrients, vitamins and water should be supplemented mainly for the strengthening of substance metabolism and sweating and dehydration. If you rush to blindly relieve fever, you may mask the condition and delay the diagnosis of the underlying disease.
