Low fever

Low fever: normal human body temperature, oral temperature is generally 35.8 ~ 37.4 ℃. In a normal state, the body temperature of a normal person should not be higher than 37.5 ° C. If it is often higher than 37.50 ° C, it is low heat. Normal people's body temperature is not exactly the same, generally lower in the morning, higher in the afternoon, lower in winter, and higher in summer; women's body temperature is also slightly higher before menstruation and during pregnancy. But these are not in the low heat range, but normal physiological changes.
