The average normal body temperature is between 36℃ and 37℃ (underarm). If it exceeds this range, it is fever, 37.3_38℃ is low heat, and 38. 1_4 1℃ is high heat.
There are differences in body temperature in the morning and evening, in all parts of the human body and between men and women. The normal body temperature has a relatively stable range, but it is not constant. It can fluctuate with gender, age, day and night, sports, emotional changes and other factors, but this change is often within the normal range.
Extended data:
Body temperature is the lowest at 2-6 am and the highest at 4-8 pm, and its range is about 0.5-65438 0℃. This regular fluctuation of day and night is due to the corresponding periodic changes in people's long-term lifestyles such as activity, metabolism and blood circulation.
However, people who have been engaged in night work for a long time have periodic fluctuations in body temperature, which rises at night and drops during the day.
Women are slightly higher than men, slightly higher in premenstrual period and early pregnancy, and the ovulation period is lower. This fluctuation is mainly related to the progesterone secretion cycle, and the higher body fat of women than that of men should also be a reason.
