Dr. Tokushima Ishihara, a Japanese natural health expert, proposed a more precise range: the ideal body temperature is 36.5℃ ~ 36.8℃. Body temperature fluctuates slightly within 24 hours, with the lowest at 2-6 am and the highest at 1~6 pm, and the fluctuation generally does not exceed 1℃.

Different people have slightly different body temperatures. Children's body temperature is slightly higher, reaching 36.8℃ ~ 37℃; Babies and the elderly have lower body temperatures. The average body temperature of women is about 0.3℃ higher than that of men, and it will change with the change of menstrual cycle. Anemic women's body temperature is 0.7℃ lower than that of women with normal hemoglobin, and their heat production is less 13%.

normal body temperature

Three parts are commonly used to measure body temperature, namely mouth, armpit and anus:

The normal anus temperature of children is between 36.5℃ and 37.5℃.

Children's oral temperature is between 36.2℃ and 37.3℃;

The temperature under the child's armpit is between 35.9℃ and 37.2℃.

After measurement, when children exceed the normal range by more than 0.5℃, it is called fever. Below 38℃ is called low fever, and above 39℃ is high fever.
