An increase in body temperature can improve the body s immunity, why haven t humans evolved in the d

Because the situation of global warming is very serious now. One of the most mentioned points is that it has an extremely high metabolic rate, maintaining body temperature at about 40 degrees Celsius, as a way to inhibit the replication of the virus. Humans and bats react differently to the invasion of the virus, and the human immune system tries to kill it all, resulting in a strong inflammatory response.

There are white blood cells in the human body, and when the body is infected, the number of white blood cells will increase dramatically to control bacteria, so the person's body temperature will also rise.

I don't know if you have heard of such a sentence, an increase in body temperature can improve immunity, you must know that this sentence is true, an increase in body temperature will indeed affect our immunity, but this effect may be good, or it may be bad, so let's introduce it to you.

First of all, we must know that the normal temperature of our human body temperature should be 36 degrees 5 to 37 degrees 2, as long as our body temperature is maintained in this range, it is normal, but we must know that for babies, their immunity will be relatively low, so they will get some diseases, so many parents want to improve their children's immunity, so they will give their children a lot of vegetables and fruits in life, let children exercise more, drink more milk, but these ways will indeed be able to improve children's immunity. Secondly, we must know that once our physical strength is raised, the function of some immune cells in our body can be continuously improved, and some pathogenic microorganisms in the body can even be killed by high temperature, so the increase in body temperature can improve our immunity. Finally, if the body temperature rises, although we will have some discomfort in the body, and even the occurrence of fever, it will accelerate the metabolism in our body, and it will also accelerate the metabolism of substances, interfering with the normal physiological functions of the digestive system and nervous system.

It can be seen that the increase in body temperature can improve immunity, but it is not recommended to take such a method for urinating, if you want to increase immunity for children or yourself, you still have to exercise more, pay more attention to diet, eat more fresh vegetables and fruits, so that the increased immunity is not only very healthy, but also will not have a certain harm to our body.

You can also improve your own immunity by maintaining a happy mood and basking in the sun, because if you spend more time in the sun, it can promote the development and growth of our bones, and it can also help us enhance our own immunity, so it is very reliable to improve immunity through these physical **.

It is true that an increase in body temperature can affect immunity, but its effects can be mixed. Benefits of high body temperature: The higher the body temperature, more immune cells in the human body will be activated, the function of certain immune cells will be enhanced, and even through high temperature, the invading pathogenic microorganisms will be annihilated to maintain human health.

Disadvantages of increased body temperature: Rising body temperature accelerates the metabolism of substances, interferes with the normal physiological functions of the digestive system and nervous system, causes symptoms such as water loss, irritability, decreased appetite, and sometimes reduces the body's ability to fight infection.

There is no scientific basis, after the body temperature rises, it is very likely that there will be a fever, which may affect breathing, may affect physical fitness, and may affect the body's immunity.

Yes, a proper rise in body temperature will improve the body's resistance, because there will be microorganisms, bacteria, and fungi in the human body, which are unbearable to high temperatures, so they will be properly sterilized.

Some people are skeptical, because an increase in temperature helps to improve immunity, why can't humans evolve a higher body temperature? Any biological organism that can survive will achieve maximum environmental levels based on its own biological characteristics. As the saying goes, there is a disadvantage.

Adaptation, in essence, is a balance of profits and disadvantages. The body temperature of the organism is also "maximized" for adaptation. Exceptions are the body temperature and immunoreactivity involved in this issue.

Increasing temperatures do improve immune responsiveness, which is supported by increasing evidence. Fever is an animal that is used to deal with the physiological response of a microbial infection. The study found that core body temperature (hyperthermia) caused by fever increased survival in the event of infection; In contrast, the risk of death is increased.

For example, in studies of infected influenza, it has been found that the use of degenerative agents lowers body temperature, which may lead to an increase in mortality from influenza5 and an increase in the proportion of severe hospitalizations. Similar findings have been made in animal experiments. For example, rabbits infected with the viral virus use aspirin have a mortality rate of 70.

It accounted for only 16 percent of the mortality rate in its natural fever group. The study also found that a variety of warm-blooded animals that may cause fever when infected can activate fever, a war mobilization mechanism, to increase body temperature. Even in cold-blooded animals, it has been observed that the infection will change – the sun – in an attempt to increase body temperature, even if this behavior may greatly increase the risk of hunting.

As for the protective mechanisms against an increase in body temperature, there are two types:

One is the reactivity that mobilizes the immune system. This has been a testament to a large number of experiments. The other is that fever can directly resist the invasion of pathogens.

The truth is simple, pathogens are also a biology, and they also have their own optimal adaptation environment. In terms of temperature, microorganisms are usually cold and diluted, inactive in relatively hot environments, and less infectious. The flu is easy in the winter, which is a good example.

Constant animals and plants do not hesitate to maintain the "motivation" (to improve adaptability) of parasitism and infection, which is reduced by microbial parasitism and infection. This is most prominent in the prevention of fungi. Just check for a fungal infection or infection of the crawler.

There are far fewer fungi that carry or infect homeothermic arteries.

When further fever is further developed from the original temperature, it will further enhance the ability to fight infection. For example, studies have found that high temperatures of 40-41°C will reduce the replication rate of polio in mammalian cells in mammalian cells. Keeping the heat hot, fever fever, requires a huge **.

There is no morning, noon, dinner in the world. Constant temperature for animals and plants to maintain high temperatures itself requires a high **. One of the costs is the consumption of a lot of heat, which means that a lot of energy is required.

With the exception of highly developed humans, with modern technology, it is not easy for any animal to obtain - life activities ——, most importantly to keep the temperature of food stable.

Because the higher the body temperature, the various organs in the body cannot bear it at all, and the brain cannot adapt to such an environment, so there is no change in this aspect.

Because we can't evolve, the evolution of human beings is not something we can control.

If the body temperature is too high, it will also cause some damage to the body. The body temperature rises only when humans are sick.

An increase in body temperature can enhance the body's immunity, so why didn't human evolution develop in this direction?

Before the advent of medical drugs, people had thick hair, and less hair can be seen as a more thoroughly evolved person. When there is thick hair, the virus is not less than today, humans are frequently infected, the body temperature is higher, more than the degree, the metabolism is fast, but it is not beneficial for the brain and lifespan. When clothes appear, hair decreases, the brain develops favorably, metabolism slows down, life expectancy increases, drugs and other means are used to fight viruses and bacteria.

Slightly higher body temperature, although it will be able to kill the virus and improve immunity, but it will also consume a lot of energy, and these energies need more food, water and minerals to maintain the normal operation of the body, and at the same time, it also needs a more effective body temperature constant mechanism to avoid the loss of heat in the body, and a large increase in body temperature, many beneficial bacteria will also be killed in large quantities, which is not conducive to physical health, so through long-term evolution, we have found an optimal body temperature relative to the human body.

Although high body temperature will improve human immunity and inhibit bacteria from entering the human body, prolonged high temperatures will harm human healthOtherwise, we will not go to the doctor because of fever, when the temperature of human beings is too high, it may burn out other systems of the body, which has great disadvantages. People belong to homeothermic animals, and for homeothermic animals, the most important thing is to put themselves in a suitable environment, to be able to maximize the use of their physical skills in this environment, that is, to be able to cooperate with each other in all aspectsIt can release the most energy while saving the most, so it is not the most suitable choice to say that the body temperature rises.

High body temperature also requires a greater cost, and every time the body temperature rises by one degree, the basal metabolism needs to continue to increase, and the cost of doing so is greaterImproving basal metabolism requires more energy, and these energies need to be obtained from natural life, natural resources are not endless, in the face of such a large population base, if people really have a high body temperature, the demand for natural resources will be great, and it is naturally difficult to attack human life.

We all know that when we exercise a lot, the body temperature will also rise, which also shows from the side that if there is a steady stream of exercise, the body temperature of human beings will also rise, and the body temperature of birds will be kept above 40 degreesCompared with birds, humans exercise less and do not evolve towards high body temperature, which is the most suitable for human life. So,The higher the body temperature, the better, if there is a good thing, then there will be a disadvantageWhat we should do is the best solution.

Because the human body temperature is maintained at the current temperature, it may be the most suitable for human development, and it is also the most suitable for human survival, so there is no development in the direction of body temperature increase.

Fever occurs when a person has a viral infection because the body's immune system is working to raise its body temperature to kill the virus. This is the natural law of human development.

Because the body temperature of the human body is too high, it will damage the brain and also affect the life expectancy of the person, so it will not develop in this direction.

The main reason is that Lingqin's current global warming situation is very serious, and we human beings are also in order to adapt to the entire environment, so we will shout towards purification in the direction of high body temperature.

Because the body temperature is slightly higher, although it will be able to kill the virus and improve immunity, it will also consume a lot of energy, and these energies need more food, water and minerals to maintain the normal operation of the body, and at the same time, it also needs a more effective body temperature splitting and concealing hand constant mechanism to avoid the loss of heat in the body, and a large increase in body temperature, many beneficial bacteria will also be killed in large quantities, which is not conducive to physical health, so through long-term evolution, we have found an optimal body temperature relative to the human body.

Because humans can't adapt to high temperatures, if the temperature is beyond the range of the human body, then the human body will die.

It's related to the living environment, it's related to the physical condition, and it's related to the virus, so we haven't evolved in this way.

To maintain a higher body temperature, you need a higher metabolic capacity, which means you need to eat and digest all day long.

Because if the body temperature rises and it comes immediately, it will cause a lot of trouble, and naturally it is impossible to evolve in this direction all the time.

This is because the higher the temperature, the organs in the body will not be able to withstand it, so it is necessary to maintain a constant temperature to function normally.

The main reason is that humans have to adapt to the environment on the earth, and if the body temperature is too high, they will not be able to survive on the earth.

Because if the person's body temperature is too high, it will cause the activation of cells to increase, which means that it will decrease.

Because the direction of human evolution is determined by the environment, we will not evolve towards high body temperature just to improve immunity.

Because many enzymes in the body cannot function properly after high body temperature, enzymes are mainly made up of proteins, and when the temperature is too high, the proteins will denature and lose their effect.

According to the data, for every 1 drop in human body temperature, immunity decreases by about 30. When the body's body temperature rises1, immunity increases by a factor of 5-6. In short, the higher the body temperature, the stronger the immunity.

Why does an increase in body temperature improve immunity? This is because, when the body temperature rises, it will activate more immune cells in the body, which can better destroy the invading pathogenic microorganisms and maintain good health.

Human immunity depends primarily on white blood cells, most of which are found in the body's blood and lymphatic vessels. Only a small fraction is found in tissues other than blood vessels and lymphatic vessels. When bacteria invade the body, the white blood cells will be deformed and pass through the capillaries, the walls of the blood vessels to the point where the bacteria invade and envelop the bacteria.

An increase in body temperature can speed up blood flow, so the rate of production of white blood cells will also increase, so bacteria can be eliminated more quickly.

At the same time, due to the increase in body temperature, the activity of enzymes in the human body also increases. As we all know, enzymes are very important catalysts in the human body, which govern the metabolism, nutrition and energy conversion of the human body, and temperature affects the activity of enzymes. The activity of the enzyme decreases at low temperatures and may even lose its activity.

Therefore, within a certain range, the higher the temperature, the higher the enzyme activity, so the stronger our metabolic capacity and the higher the immunity.

That being the case, why haven't humans evolved towards high body temperature?

Body temperature can be divided into two parts: surface temperature and core temperature. Surface temperature is greatly influenced by the environment.

For example, we have cold winters and hot summers, and although the core temperature is relatively stable, it can also fluctuate due to age, day and night, and exercise, but the fluctuation range usually does not exceed 1°C.

When we usually measure body temperature, we are actually measuring core temperature. When we use the armpit to measure body temperature, the upper arm is close to the chest and then a closed cavity is formed. As the temperature in the body continues to diffuse, it takes about 5 to 10 minutes, and then the temperature in the cavity is already close to the core temperature, usually between 36 degrees Celsius and Celsius.

Therefore, the body temperature cannot be increased casually.
