Body temperature 36.8℃
Under normal circumstances, a body temperature of 36.8°C is considered within the normal range and does not indicate fever. Normal body temperature varies slightly depending on the measurement method, but whether measured under the armpit (axillary), in the mouth (oral), or rectally, a temperature of 36.8°C falls within the normal range. The details are as follows:
Typically, the normal oral temperature ranges from 36.3°C to 37.2°C, axillary temperature from 36.0°C to 37.0°C, and rectal temperature from 36.5°C to 37.7°C. Since 36.8°C does not exceed these normal values, it is not considered fever. Human body temperature is relatively stable, regulated by the body's thermoregulatory center and neurohumoral mechanisms to maintain a dynamic balance between heat production and heat dissipation.
In clinical practice, a body temperature of 37.3°C or higher measured under the armpit is defined as fever. Fever is further classified into low-grade, moderate, high, and hyperpyrexia based on severity. Low-grade fever refers to a temperature between 37.3°C and 38°C; moderate fever between 38.1°C and 39°C; high fever between 39.1°C and 41°C; and hyperpyrexia refers to a temperature exceeding 41°C.
If a patient develops symptoms of fever, it is recommended to seek timely medical evaluation at a hospital to avoid delaying diagnosis and treatment.
