Symptoms of high fever in babies

Body temperature represents numbers: Fever means when the body's central temperature is greater than or equal to 38 degrees, the disease and inflammation produced in the body will change the body temperature positioning point, thus causing a fever.

Increased temperature positioning: When a child first develops a fever, he or she will feel chills all over and cold limbs. This is because the body temperature positioning point is raised, and this period can be called the chill period.

Fever and antipyretic period: When the body temperature rises to the fixed point, the body will warm up and you will feel feverish and have a headache. This is called the fever period. After using medicine to reduce fever, or after a while, the body temperature fixed point will drop, making the body feel warm and sweating to reduce fever. This is called the antipyretic period.

Rectal temperature: Rectal temperature is the closest to the body's core temperature. However, for infants under three months old or newborns who are too light, rectal and ear temperature measurements are not suitable. It is recommended to use axillary and back temperatures instead.

Common causes of fever in babies

Acute gastrointestinal inflammation: This disease is often accompanied by high fever, nausea, vomiting, diarrhea and abdominal pain.

Acute bronchitis: This disease is often accompanied by fever, cough, chest tightness and pain, and even shortness of breath; the above conditions can also occur when the lungs are inflamed.

Can a fever damage your brain?

Control over inflammation: The human body has undergone a long period of intelligent evolution, so the human body has a very precise regulatory control mechanism for the fever caused by the inflammatory response, and will not keep the body temperature in an infinitely rising state. Therefore, the fever is usually not higher than 41 degrees.

Fever protection function: In fact, fever has a protective effect on the body. When the body temperature rises, the body environment will be unfavorable for the growth of bacteria in the body, and fever will cause the release of inflammatory hormones, which can enhance the effectiveness of the immune system to fight against bacterial infection.

Does not weaken brain function: Therefore, fever itself does not actually affect brain performance, unless it is some special serious diseases such as meningitis, it will cause sequelae of brain lesions.
