Why is the body temperature of a person 37 degrees 90

The body temperature of a healthy person is around 37 degrees Celsius, and the temperature of the day and night is slightly different, but the difference is not more than 1 degree.

Human activity consumes energy, just as an electric fan consumes electricity to turn. The energy produced by the human body is mainly converted from food. Rice, fish, vegetables, etc., which are eaten during meals, are digested and broken down into various nutrients.

Energy is produced by the continuous chemical reactions of nutrients in the human body. These chemical reactions must rely on the help of various enzymes in the human body that are very sensitive to temperature. The most suitable temperature for the activity of the gelatinous enzyme is 37 degrees Celsius.

When the body temperature drops, the activity of enzymes decreases, the chemical reactions in the body slow down, and the body produces less energy. If the body temperature is below 30 degrees Celsius, brain activity will be affected; Below 22 degrees Celsius, the heart stops beating. If the body temperature is high, it is not okay, as high as 41 degrees Celsius, the child will have convulsions; Above 43 degrees Celsius, it can cause death.

The normal body temperature of the human body is uniformly controlled and regulated by the brain, and usually, the brain maintains a normal body temperature through the heat production system in the human body, such as muscles, liver, heart, brain, etc., as well as through the heat dissipation system in the human body, such as sweat glands, **, etc.

The body temperature of the human body is relatively constant, and does not change due to the difference in external temperature, and remains at about 37. Temporary, slight fluctuations in body temperature may occur due to diet, exercise, environment, mood, and gender, but this is not clinically significant, while fever refers to a pathologic increase in body temperature. Extrinsic fever refers to the pathological increase in body temperature caused by extrinsic factors.

Externally induced fever accounts for a high proportion of the incidence of internal diseases, affecting work and life, and in severe cases, dizziness, convulsions, and even life-threatening may occur. Traditional Chinese medicine has a systematic theory and rich clinical experience in external fever, and has a relatively ideal effect.

It is the optimal temperature for various enzymes in the human body.

In fact, the human body temperature is not just 37 degrees, it changes every day.

The temperature generally rises in the order of armpits, mouth, and colon.

The general 37 degrees is the armpit temperature.

This is a biological problem, very simple - human beings are homeothermic animals, and the activity of various enzymes in the human body can reach the highest state at 37 degrees, which is most conducive to the human body to adapt to the natural environment.

This is Darwin's theory of evolution – survival of the fittest.

Humans set their body temperature at 37 as an evolutionary choice.

It is precisely because the constant body temperature is 37 degrees Celsius that the complex chemical reactions can be fixed in the optimal state, so that humans and other homeothermic animals can adapt to various complex activities in daily life. It is also the result of the endurance contest between predators and ** in the biological chain in the process of biological evolution.

To maintain a constant body temperature, it is necessary to choose a point where heat production and heat dissipation are most easily balanced. At this temperature, the heat generated by the body's activities is most likely to balance with the heat lost by the body in the environment, and it is easiest to maintain a constant body temperature.

A human body temperature of 37 is set for the same reason as a room at 27. When humans appeared in Africa more than 2 million years ago, the average daytime temperature was below 25.

In this climate, when the human body temperature exceeds 35, the heat generated by activities such as hunting through metabolic processes is most likely to be dissipated.

Introduction: The human body basically maintains a constant body temperature ---36 37, in this range, one degree higher or one degree lower will make people feel uncomfortable, the normal body temperature of a person is 37 degrees, what is the reason?

1. What is the reason why 37 degrees is the normal body temperature of the human body?

The human body in the environment of 37 can be conducive to the metabolism of the human body, so as to maintain the normal health of the human body. The normal body temperature of the human body can be different, which is due to the fact that the body's metabolism is affected at different times and in different environments, resulting in different basal metabolic rates of the human body, causing fluctuations in body temperature. Normal body temperature fluctuates within 1 per day, if the body temperature fluctuates more than 2, it means that the patient's body temperature is abnormal, and this situation needs to be checked in time to clarify**.

Second, the temperature is too high or too low to the human body.

Too high or too low temperature will cause changes or even loss of enzyme activity, resulting in physiological dysfunction and serious consequences. Therefore, it is of great physiological significance to keep the body temperature relatively stable, and the human body temperature can be maintained within the precise range of 1 difference, because the human body has a very complete body temperature regulation system, under the effect of regulation, the body's heat production and heat dissipation can be maintained in balance. Therefore, if the temperature of the human body is too high or too low, people will feel uncomfortable.

It is necessary to go to the hospital for a check-up in time to determine**.

3. How does the human body regulate body temperature?

There is a set of systems and organs in the human body that regulate body temperature, just like the air conditioner we install at home, which constitutes the body's "thermoregulator", and the complex brain controls the body precisely, and this regulatory mechanism is called "hypothalamus". If the body is cold, in order to be able to save heat, the blood vessels will contract, and if the body feels too warm, the blood vessels will dilate, and at the same time, hormone information will go to the sweat glands, which secrete sweat through the pores of **. That is, putting on or taking off clothes, always with the aim of maintaining a fixed body temperature.

Because all kinds of active enzymes in the human body are reacting in time, and humans are homeothermic animals, in order to better contact with the outside world, so they will be kept at about 37 degrees.

Because people need to promote the body's metabolism in a certain environment and temperature, so as to maintain a healthy state, this is the normal temperature difference of the human body.
