What is fever?

Normal human body temperature within a certain range of fluctuation. General axillary temperature is 36-37.4 ° c, so it is often the temperature over 37.5 ℃ as fever. And further divided, 37.5-38 as a low-grade fever, 38.1-39 ° c moderate fever, 39-40.4 ° c for high fever more than 40.5 ° c for super high fever.

Normal fluctuation of temperature easier in children, infection, environment and sport, and many other factors may make changes in body temperature in children. Rise is not necessarily abnormal rise of body temperature in children, which means that increases in body temperature is not necessarily heat. If a transient temperature fluctuations, but the body in good condition, and when no other exception performance, children should not be considered is in heat, may be caused by the following non-disease factors.

Normal human body temperature to rise after exercise. Children crying, nurse after the normal physiological activities, such as body temperature will also rise. Normally, the temperature will not rise too high, mostly between 37.5-38 ℃. Temperature rises due to crying, milk and other normal physiological activity causing muscle generates more heat. These reasons lead to increased body temperature, stop will quickly return to normal levels after exercise. When you encounter these situations, parents are welcome to continue to observe the child\'s temperature change, generally do not need any treatment.

So-called abnormal increase in body temperature refers to the heat not only elevated body temperature, should also exist at other disorder caused by diseases, such as: pale, accelerated respiration, emotional instability, such as nausea, vomiting, diarrhea, skin rash. Diseases due to individual differences in children and for different reasons, fever and there is a big difference. Like with pneumonia, some children fever is not high, some children hyperpyrexia 39-40 ℃, and fever in the sense of sustainable 2-3 on days, lasting several weeks and septicemia. The onset of fever have acute and sustained, and some fever chills followed first; some fever was high but cold limbs and forehead, so hand and forehead fever sometimes subtle touch limbs and touch can feel children with fever of chest and abdomen.

In addition, from a disease of the brain, lesions violation of thermoregulation, nerve conduction system or the central nervous system tissue and organ function associated with the heat production (such as hyperthyroidism) or ambient temperature is too high (such as heat stroke), as well as skin skin thermal dissipation of the serious damage caused under such circumstances, the body\'s temperature is rising, sometimes reached very high levels. This phenomenon is not a fever, but overheating.

Parents should be aware of is when the child\'s body temperature above the normal range, especially when there is a high fever, do not panic. First determine the accuracy of temperature measurement, you should also carefully consider the reason caused temperature rises and, if necessary, should take children to the hospital in a timely manner, so as to avoid delays in diagnosis and treatment of disease.
