Is what feverish?
Fever, which is called fever in medicine, refers to the human oral cavity temperature (oral temperature) greater than 37.3 ℃, axillary temperature (axillary temperature) greater than 37 ℃, or rectal temperature (anal temperature) greater than 37.6 ℃. So, how should adults correctly measure body temperature? Measurement conditions: Before taking your temperature, Can’t eat, You can’t walk and other sports, Stay quietly indoors for more than half an hour. The body temperature measured in this way is the real body temperature. Measurement position: Compared with axillary temperature, which is affected by sweating, The temperature obtained by measuring the mouth temperature is more accurate. Measurement posture: Throw the mercury surface of the sterilized thermometer below 35 degrees, Then the head of the thermometer is placed under the tongue, Close your lips tightly, After 5 minutes, see how much mercury rises. Measure frequency: Because normal people’s body temperature will also have high and low changes at different times every day, you can take it several times more, or when you think your body temperature is the highest. Measurement records: the highest body temperature every day is the most valuable for judging the disease. Generally speaking, after correctly measuring the body temperature, the highest temperature is 37.3 ~ 38 ℃, which is called low fever. And above 39 ℃, is high fever. Some people will ask, doctor, my usual body temperature is only 35.9 ℃, now there is 36.8 ℃, is it a fever? If the temperature difference within a day is greater than 1 ~ 1.2 ℃, it is also considered a fever. You don’t count. What? You said you burned above 41 ℃? Oh, that’s super-hot. 42 ℃? The bird is just like this (40 ± 2 ℃). I can only congratulate you on your sober mind. It is said that the highest body temperature recorded by human beings is 49 ℃. If you can still live, you really want to thank God. Why do people have a fever? The human body’s body temperature regulation system the human skeletal muscle and liver are the main heat-producing organs. 1. The human body’s skeletal muscle and liver are the main heat-producing organs. The skin is the main radiator. The human brain has a thermoregulatory center, which continuously issues instructions to coordinate the heat generation and heat dissipation of the two organs, keeping the body temperature within a narrow range of 36.2 ~ 37.2 ℃, which is conducive to maintaining human health: what if it is cold? -[heating basically depends on shaking], the brain said, skeletal muscle you to produce heat, shaking is hot. What if it is hot? -[On the afternoon of the weeding day, sweat drips down the soil], the brain said, the skin you open pores, if you don’t have time to remove heat, sweat! 2. Is what causing the fever? [How can a man not get sick when he eats grains? —————————– The human body is indeed affected by various diseases. Viruses, Bacteria, Often like to drill into the human body, Complete their task of carrying on their families. They will produce something before or after death. We call it exogenous pyrogen, They are foreign [bad guys] who cause fever. After they invade, The human body has to resist. White blood cells produce a pile of cytokines to attack them. Unfortunately, many of these cytokines can also cause fever, called [endogenous pyrogen]. Tumors and other diseases can also produce these endogenous pyrogen themselves. After the brain is stimulated by these pyrogen, it is like a stimulant. Hi! Just raise the body temperature. 3. How does the body temperature rise? Heat production increases and heat dissipation decreases. The liver is a big factory of the human body. After taking stimulants, the workers work overtime, metabolism is vigorous, and heat production increases greatly. At this time, skeletal muscle produces relatively little heat, unless you are [shivering] (shivering); Then, the skin can’t keep up with the heat dissipation speed, and even closes pores (it thinks it is very cold when shivering). In this way, a fever occurs. Is fever really a good thing? There are rumors on the Internet that fever is a good thing and should be allowed to occur. Is this really the case? Benefits: It shows that the body is removing pathogenic bacteria and is stimulated by heat sources. The body is like a stimulant, Not only does it raise your temperature, At the same time, it also mobilizes the immune system in the body, The whole body’s cells, body fluids and defense forces have been mobilized. Eat what foreign pathogens should eat, Kill what should be killed, What cannot be killed also makes you grow poorly (the appropriate temperature for bacteria to grow is generally 35 ~ 37 ℃). Therefore, Fever is beneficial to some extent, Can not rely on the action of foreign drugs, You can get rid of the pathogens in your body, In a short time, the problem will be cured. Disadvantages: If you have a fever for too long, Too much physical consumption, It’s dangerous, but, You can’t keep your body feverish, It’s like stimulants can’t be used too much and too long. It consumes a lot of logistical supplies, There is also a lot of garbage that cannot be removed. At this time, the combat capability of the defense forces gradually decreases. The high heat lasts too long, Not only did the brain not command the troops, but it also screamed at the top of its voice for half a day. It also failed to do so. Eventually, it entered a state of suppression coma. However, children could even suffer from febrile convulsions due to imperfect brain function. These situations are very dangerous. They must seek medical treatment in time and seek medical help. The how correctly handled the fever? First of all, the body temperature should be measured correctly and the daily body temperature changes should be recorded, especially the highest body temperature. This record will be a good helper for doctors when seeing a doctor. How to deal with fever correctly? 1. Take medicine for the disease. If you have just started to have a fever, you can use some antipyretic. If you still have runny nose, nasal obstruction, sneezing and other symptoms, The body temperature is very high, You can also use some cold medicine appropriately. Just take it when you feel uncomfortable. You don’t need to take it regularly. Also don’t take too much. These suggestions are all aimed at adults. Due to space constraints, Pediatric medication is not discussed in this article. 2. Drink more water. If it is only an acute fever (less than 2 weeks), Not accompanied by other symptoms (such as severe cough, purulent sputum, headache, etc.-these are often signals that the body cannot process by itself), Mental state is good, You can wait and see, Drink more water (to help the defense forces work). However, it is still recommended to see a doctor as soon as possible. 3. See a doctor as soon as possible. If your fever lasts for more than 3 weeks, The body temperature exceeds 38.3 ℃ many times, After at least one week’s preliminary examination by doctors, If we can’t tell you it’s what’s diagnosis, Then I can only regret to tell you that this is called [fever to be checked], which is a very challenging category of diseases in medicine. It requires an experienced doctor to give you a symptomatic examination (it is not the right medicine at this time), and even it may not be clear in the end. All you can do is cooperate with the doctor. Responsible editor: Zhang Qing Photo Source: Shutterstock.com
