At this stage, people are very sensitive to fever. Before the winter of 2019, fever was just a cold. After that, it would be normal. Even if some people have fever in their lives, they would not be particularly worried.

At this stage, people are very sensitive to fever. Before the winter of 2019, fever was just a cold. After that, it would be normal. Even if some people have fever in their daily life, they would not be particularly worried.

However, with the arrival of the new coronavirus epidemic, one of the most common symptoms after being infected with the virus is fever. Therefore, if some people have fever at this stage, they will also feel very worried and worried.

Under the premise of good health, why are the measured temperature data similar?

In daily life, some people are very concerned about their health. When they feel slightly uncomfortable, they may take out their thermometer to measure their body temperature to see if they have a fever.

Most of the time, people are very healthy and generally do not have fever, so the measured body temperature is almost between 36 degrees and 37 degrees.

People find it very difficult to understand this situation. For example, a person's body temperature is 36.5 degrees, but it is measured as 36.5 degrees in winter and still 36.5 degrees in summer.

This will inevitably cause people to think deeply. The temperature difference between winter and summer is relatively large. Why does human body temperature remain constant?

The main reason why this is the case is that humans are endothermic animals. That is to say, when we are in any temperature environment, the temperature of the body is generally constant, and the reason for keeping the body constant is the thermal energy system in the body.

Just imagine, if the temperature of the human body changes with the external environment, the body temperature of people living in high latitudes is very low, while the body temperature of people living in low latitudes is very high. Then when people from high latitudes arrive in low latitudes, the extreme changes in body temperature may cause serious harm to the body.

What is the normal body temperature of a person ?

Faced with this problem, many people may agree that the answer is 37 degrees. Take out a thermometer and observe it. You will find that 37 degrees in a row of numbers is often marked with a special symbol.

The purpose of the mark is to remind people that this is a normal temperature. If it exceeds 37 degrees, it means that the human body has a higher temperature.

Strictly speaking, the normal human temperature is 36 to 37 degrees, but exceeding 37 degrees is not considered a fever. Authoritative data shows that it is called a fever only when the body temperature is greater than or equal to 37.3 degrees.

Different degrees of fever are as follows:

Low fever: 37.3℃~38℃

Moderate fever: 38.1℃~39℃

High fever: 39.1℃~41℃

Ultra-high fever: ≥41℃

Because people don’t know enough about this aspect, many people think that a fever of 38 degrees is already very serious. In fact, 38 degrees is just a low-grade fever.

After recent real experience, I believe people have also learned that doctors do not recommend taking medicine when the fever reaches 38 degrees Celsius.

Because you can completely rely on physical cooling to control the temperature below 38 degrees 5, there is no need to take drugs. If the temperature is above 38 degrees 5, if the temperature is still not under control, it is likely to cause abnormalities in certain systems and states of the body, so you need to take drugs at this time.

What will happen if the fever exceeds 40℃? Hope everyone knows

Many people may have experienced fever. If the fever temperature is very high, people will feel cold. This situation also makes people a little confused. It is obvious that the body temperature rises when fever occurs, why do they feel cold?

This is mainly because when a person's temperature reaches 40 degrees, they will reduce heat to ensure the contraction of the skin and blood vessels. At this time, skeletal muscles also begin to tremble, and the body's heat is reduced, which inevitably makes people feel cold.

Many people often say that they feel pain in the seams of their bones when they have a high fever. This is because muscles contract during the fever process to maintain heat, and the main function of muscles is to protect bones, so it is likely to affect the state of the bones. At the same time, fat in the body is also burned during the fever process (never lose weight through fever).

If the human body's fever exceeds 40 degrees, it will destroy the body's temperature-regulating system. If things go on like this, it may also lead to massive necrosis of proteins and cell membrane , eventually leading to organ failure and life-threatening consequences.

Under normal circumstances, if the body's fever temperature is around 39 degrees, and you feel headache, muscle soreness and no other abnormalities at the same time, this is likely to be related to viral infection.

In addition to infection with new crown , what other diseases can cause fever?

. Infectious diseases

The so-called infectious diseases mainly refer to viruses and bacterial infections, such as tonsillitis , otitis media , tuberculosis urinary tract infection, skin infection, etc. These diseases may cause fever when they appear, so I hope you can view this issue correctly.

. Blood system diseases

such as acute leukemia, chronic leukemia, lymphoma, etc. are all blood system diseases. When these diseases occur, they may also cause fever reactions.

, rheumatic immune diseases

such as systemic lupus erythematosus , rheumatoid arthritis, rheumatoid arthritis , dermatomyositis , etc. are all rheumatic immune diseases. The occurrence of these diseases will also cause fever reactions.

In summary, if you have a fever for a period of time, don’t panic too much, because there are many causes of fever. I hope you can find the real cause, prescribe the right medicine, and get corresponding treatment and conditioning.
