During the epidemic, the temperature was measured every day. Do you know what the normal temperature is?

In 2020, a sudden epidemic disrupted everything. China went all out to successfully control the epidemic!

Although there were few new cases in China, the epidemic situation abroad began to get out of control and imported cases began to appear in various places.

All these remind us that the current epidemic prevention and control can't be relaxed, so we can take the means of transportation, enter office buildings, residential areas, street shops, parking lots, and get off the expressway, and we can all see staff taking temperature tests.

Although everyone's temperature is measured by forehead temperature measuring gun every day, how much do you know about body temperature? Let's study together!

mercury thermometer

The measurement error of mercury thermometer is small, but the number displayed by mercury thermometer is small and the measurement time is long, which is inconvenient for active children and people with unstable emotions.

Moreover, the mercury thermometer was accidentally broken, and the mercury in it may cause pollution or affect health.

Electronic clinical thermometer

Electronic thermometers are relatively safer without mercury. It can directly display the temperature, and the measurement speed is short, but its accuracy is not as good as that of mercury thermometer, and it is easily influenced by external factors, so it takes many measurements to get the median value.

Infrared forehead temperature gun

The forehead temperature measuring gun is simple to use, and the measuring time of the thermometer is short, so there is no need to directly contact the skin surface. At present, it is widely used in prevention and control work in novel coronavirus, but the accuracy of forehead temperature gun is low (the exposed forehead skin temperature is unstable).

Infrared ear thermometer

Infrared ear thermometer can measure body temperature by measuring the radiation brightness of eardrum in just a few seconds, but it is more difficult than other thermometers at the initial stage of operation and requires skilled operation.

In fact, people's body temperature fluctuates at different time periods.

Generally speaking, the body temperature will be slightly lower in the morning and slightly higher in the afternoon, but the fluctuation range will not exceed 65438 0℃ within 24 hours.

In addition, the body temperature will be slightly higher after exercise and eating, and the body temperature of women or pregnant women before menstruation will be slightly higher.

Axillary temperature

36~37℃

This is the most commonly used method to measure body temperature.

Oral temperature

36.3~37.2℃

The result of oral measurement is better than that of axillary measurement.

Closer to the real temperature of the human body.

Anal temperature

36.5~37.7℃

Anal measurement is stable.

Closest to the real temperature of the human body.

But it is mainly used for babies and the unconscious.

If it exceeds 37℃, it can be considered as fever, and the specific degree of fever can be judged according to the oral temperature. The fever can be divided into:

?

Under normal circumstances, our body's heat production and heat dissipation are in dynamic balance.

Body temperature will not rise for no reason. If you find that your body temperature is higher than normal, you still need to pay attention to whether the measurement is accurate and take multiple averages.

If many measurements are still higher than normal, you need to see a doctor as soon as possible according to your physical condition.
