It is common for babies to develop fever and generalized fever, which is often caused by bacterial or viral infections. When infected by bacteria or viruses, the bacteria and viruses in the body will multiply and produce a lot of toxins, which will stimulate the baby’s thermoregulatory center in the body, causing the temperature adjustment point to move up, and the body will have fever symptoms. Fever is often caused by increased heat production and decreased heat dissipation, so the phenomenon of generalized fever may also occur, and it is necessary to treat the fever at this time. However, the phenomenon of generalized fever is much better than the phenomenon of cold hands and feet, which often proves that the function of heat dissipation is still intact, so you can use ibuprofen suspension or acetaminophen suspension to reduce fever at this time. In general, the use of antipyretics is only recommended when the body temperature is greater than 38.5°C or 39°C.
