How does it count as a fever? 5 common senses you must know about body temperature!

In this year's special period with the epidemic as the theme, temperature measurement tends to be normal. Whether it is a community, school, office building, entertainment venue or public transportation, it is required to wear a mask and measure body temperature. If you find that you have a fever, then you will have a hard time moving.



How much is a fever?


The definition of fever is judged according to human body temperature. As long as the measured body temperature exceeds the normal body temperature range of the human body, it may be a fever.


The general temperature measurement methods are oral cavity, armpit and rectum, among which the temperature of rectum is closest to the real temperature of the body. If the rectal temperature is around 36.5℃-37.7℃, the oral sublingual temperature is around 36.3℃-37.2℃, and the axillary temperature is around 36℃-37℃, it belongs to the normal body temperature range of the human body. Once it exceeds this temperature range, it is usually considered to have a fever.


Take the underarm temperature as an example, the normal temperature is 36°C-37°C. Then 37.3℃-38℃ is considered a low fever, and 38.1℃-40℃ is considered a high fever.



What are the factors that affect body temperature?


Body temperature is not fixed, it fluctuates with changes in factors such as age, gender, day and night, exercise, and mood.


From the point of view of female body temperature, it will fluctuate greatly in the progesterone secretion cycle. Generally, the body temperature will rise slightly in the premenstrual period and early pregnancy, while the ovulation period will slightly decrease.


In other populations, children’s body temperature is a little higher than that of adults, while the elderly’s body temperature is relatively lower. In addition, the body temperature of newborn children is easily affected by changes in the outside world, because the development of the central nervous system of newborns is not perfect, and the development of skin sweat glands is not complete, so the body temperature regulation ability is poor and easy to fluctuate. The basal metabolic rate of the elderly is low, and the body temperature is relatively low.


For ordinary people, the body temperature is generally low from 2 am to 5 am, and the body temperature is higher from 5 am to 7 pm in the evening. At around 8 o'clock in the morning, around 3 o'clock in the afternoon, and around 8 o'clock in the evening, the body temperature is relatively normal.


In addition, the body temperature is relatively high after exercise and when emotionally excited, and being in a low temperature environment will also affect the change of body temperature, and the body temperature is relatively low.


How to measure body temperature more accurately?


For underarm temperature measurement, make sure that the underarm is dry before the temperature measurement, and there is no overheating or overcold thing placed under the underarm.


For oral temperature measurement, ensure that the thermometer is clean and safe. Pay attention to the use of disinfectants. Do not drink hot water or ice beverages ten minutes before the temperature measurement. Pay attention to the safety of children and avoid biting.


For rectal temperature measurement, it is necessary to ensure that the thermometer is clean and sanitary before and after use, clean and disinfected, and grasp the strength and insertion position when inserted into the body, and ensure the gentle movement.


The clinical thermometer is so dangerous, so what can replace the temperature measurement?


Traditional glass mercury thermometers have the characteristics of accurate measurement results, high stability, and low price. However, mercury is harmful to human health. Once the mercury vapor is destroyed and inhaled, it will reach the various organs of the body through blood circulation, and it can also pass through The blood-brain barrier damages the human central nervous system. There is a greater danger to babies and fetuses that are still growing. Considering the harm of mercury in clinical thermometers, many foreign countries have banned the use.


With the development of modern technology, traditional glass mercury thermometers are gradually being replaced by infrared forehead thermometers and ear thermometers. The latter is more convenient, safer and more hygienic to use. At the same time, the operation is simple, and the body temperature can be measured quickly.



How to use the forehead temperature gun, which of the forehead temperature guns on the market is worth buying?


As a basic family medical device product, forehead thermometers need to pay attention to the brand and certification standards when purchasing, so that the quality of the purchased products can be guaranteed.


With the advancement of technology, people have more and more diverse requirements for the performance of objects, and they want more functions while measuring body temperature. For example, temperature measurement can immediately display the degree, according to the height of the body temperature can be distinguished, can query the change of body temperature, can measure the temperature of other items at the same time, and can read clearly at night, etc.


Lepu launched the Jiagan Ⅲ infrared forehead thermometer

The product uses a German sensor and a pure copper condensing cup, which can gather more infrared rays while measuring the temperature in 1 second to ensure the stability and accuracy of the temperature measurement.


Use Lepu small blue spot focusing lamp, 0-5cm temperature measurement example operation specification, fully guarantee the accuracy of temperature measurement.


There is also a three-color backlight display, 99 sets of data memory, can read clearly at night, know the change of body temperature, and can record body temperature at will, which is convenient for later query.


At the same time, it also supports dual-mode switching of human temperature and material temperature, and automatically shuts down when not in use, which is more suitable for use needs.


It can be measured at a low temperature of 5℃-40℃, and the power consumption is small. It can measure more than 200,000 times continuously. Fully meet your needs.
