A body temperature of 37°C after a meal is within the normal range. The internal temperature of the human body is also called body temperature, which is relatively constant under normal circumstances. Because body temperature is affected by many factors (including eating), so it is not a fixed constant value, but a range, fluctuations within a day within 1 ℃. Normal values for oral temperature range from 36.2°C to 37.2°C, axillary temperature from 36.0°C to 37.0°C, and anal temperature from about 36.7 to 37.7°C. When body temperature exceeds normal, it is called flare-up. When the body temperature is above normal, it is called fever, and when it is below normal, it is called hypothermia. Measuring the body temperature at 37℃ after eating suggests that the body temperature is within the normal range.
