People's body temperature will fluctuate even under normal conditions, so some people will also detect that their body temperature will change. Most of them are women, especially during menstruation. So how much is fever? Let's have a look.
How much is a fever
The normal body temperature will not be fixed at a fixed value. The normal body temperature will fluctuate at different times of the day due to age activity.
Generally speaking, the temperature of different parts of the body will also be different. The temperature of the rectum is closer to the core temperature of the body. The armpit temperature we usually measure is lower. The normal range of Anal temperature is 36.5 to 37.5 , the normal oral temperature is less than 37.5 , and the normal axillary temperature is 36 to 37 . There is a gap of several degrees between the maximum normal temperature and the fever temperature. This gap is the normal fluctuation of body temperature. The American scientific association points out that Anal temperature, ear temperature and oral temperature are greater than or equal to 38 , indicating fever.
Which of the four common thermometers is accurate
1. Mercury in glass thermometer
It is the most traditional material, the most accurate measurement of a thermometer, not only can measure axillary temperature, but also can measure oral and rectal temperature.
2. Electronic thermometer
Usually it is also used to measure axillary temperature. The measuring time is shorter than that of mercury thermometer. It can be read in about 1 minute. The basic body temperature needs to be calibrated frequently. For example, 37 is measured when the thermometer is not heated, which indicates that the basic temperature of the thermometer has risen, and it needs to be adjusted. But it also means that the temperature is normal when the degree is no more than 37 .
3. Infrared ear temperature gun
It is used to measure the temperature of eardrum close to the position of lower colliculus. It is measured by infrared sensing module. Because it is non-contact, rapid measurement, children, the elderly, paralyzed, comatose patients are more suitable.
4. LCD forehead thermometer
It belongs to the chemical punctuation thermometer, which can be used after being pasted on the forehead, and can be fully contacted with the skin for about 3 minutes.
Warm tip: if you don't have time to go to the hospital with a fever, you must also do some simple cooling measures. Any measures have certain effect on the patients who are suffering from fever, such as using ice compress and warm water to wipe, which can cool the body. Alcohol cooling is also a good choice.
