Knowledge of body temperature
The temperature of human body belongs in a range and the range may vary among people. Temperature if individuals may also vary from time to time. The following table 1 indicates the temperature range of the majority people for your reference.
Human body temperature varies with time within a day, and is also affected by other external conditions, such as age, gender, skin color, skin thickness, etc. Refer to table 2 below for changes in body temperature with age.
Place | Normal Temp Range Reference |
Ear | 35.8~38.0℃/96.44~100.4℉ |
Oral | 35.5~37.5℃/95.9~99.5℉ |
Armpit | 34.7~37.3℃/94.46~99.14℉ |
Anus | 36.6~38.0℃/97.88~100.4℉ |
Table 1
Age | Normal Temp Range Reference |
0-2 years | 36.4~38.0℃/97.52~100.4℉ |
3- 10 years | 36.1~37.8℃/96.98~100.04℉ |
11-65 years | 35.9~37.6℃/96.62~99.68℉ |
>65 years | 35.8~37.5℃/96.44~99.5℉ |
Table 2
Women's body temperature is different from men's, generally about 0.3℃/32.54℉ higher than men's, body temperature during ovulation will rise by 0.3℃~ 0.5℃/32.54℉~ 32.9℉ than usual, so use this to know whether women are in ovulation period, which is conducive to fertility or contraception.
The usual method is to use a thermometer to measure the basal body temperature of a female individual every day, and then draw a graph of the basal body temperature change. The ovulation period can be clearly seen from the figure.
