What is the optimal temperature for the human body, and what is the minimum temperature of the human

The normal body temperature for humans is degrees. When the body temperature reaches between them, it is a low-grade fever; The state of medium burn is between; , which is a state of high fever. If you have a low-grade fever, it is recommended not to take fever-reducing drugs for the time being, do not take non-steroidal anti-inflammatory drugs such as ibuprofen and aspirin, and it is recommended to give physical cooling methods to reduce fever**.

If the systemic symptoms are more obvious, some Chinese patent medicines can be given for symptomatic treatment**, such as the use of small chai hu granules and other macro liquid residual grains for fever**.

Under normal circumstances, the temperature of the human body is relatively constant, between 36 and 37 degrees, and the fluctuation in 1 day will not exceed 1 degree, if it exceeds the range, it is abnormal, when the body temperature is lower than 36 degrees, it is low body temperature, most of which are caused by a decrease in basal metabolic rate, or because of serious diseases.

The most common disease is hypothyroidism, as far as the environment is concerned, the most comfortable ambient temperature of the human body is between 16 and 25 degrees, if the temperature is lower than 16 degrees, the body will feel very cold, or have uncomfortable symptoms, at this time you need to wear more clothes to keep warm, especially the elderly and frail people, more need to pay attention.

The normal body temperature of a person is generally around 37 degrees, if it exceeds 37 degrees, it is a fever, and the higher the temperature, the more serious the fever will be, and the more dangerous it will be. Generally speaking, the internal temperature of the human body reaches 42 or 43 degrees, which is already a very high temperature, which is also a limit that the human body can bear. However, the highest record of human body temperature in the world is degrees, which is actually beyond the range that people can bear, and people are not because of fever caused by high body temperature, but because of long-term work in a high temperature environment caused by the high body temperature.

Therefore, if it is found that the body temperature of the self-excited ear has reached 42 degrees or 43 degrees, then it must be very dangerous and should be sent to the hospital immediately. The maximum temperature of the human body is about 42 degrees Celsius, but if you touch something with a high temperature such as hot water, you have to divide it according to your feelings. Many people think that a cold causes a fever because the condition is getting worse, but this idea is not entirely correct, although fever is a sign of an aggravation of the disease, but it is also the result of a protective mechanism within the human body that is working.

Because the heat source directly affects the temperature control center of the human body during the fever, it will lead to the disorder of the temperature center of the human body, and the body temperature will rise if the body produces too much heat energy. If it is because the body is infected with bacteria, and the body does not produce new antibodies, it will also cause the person's body temperature to rise. This is because bacteria are detected in the body, so they want to increase the temperature to inhibit the growth of bacteria in the body, so as to improve the body's immune system so that the white blood cells in the body can kill these bacteria.

Therefore, we will find that colds are usually not easy to understand**, but after the fever, the cold will get better very quickly. <>

Fever caused by a cold is relatively common, but there are other conditions that can cause our body to heat up, such as leukemia, heat stroke, burns and connective tissue diseases. If the temperature of the body has been rising, and the temperature inside the body has reached about 42 degrees, it will affect the health and life safety of the human body. We usually read more or less people will also hear that some people burn their brains because they have a high fever and do not get a timely **, even if the fever is reduced, there will be a series of sequelae.

This is because the body's internal temperature regulation and other dysfunctions during the process of fever can lead to brain tissue injury, coma or death.

In a healthy state, if the diet is normal and the clothing is appropriate, the body temperature of the human body is generally relatively constant, that is, it is kept around 37 (roughly between, and does not change due to the change of external environmental temperature.

The average normal body temperature of the human body is between 36 and 37 (armpits), beyond which it is a fever, a low fever, and a high fever.

There are differences in body temperature between men and women in the morning and evening, in all parts of the human body, and between men and women. The normal body temperature of the human body has a relatively stable range, but it is not constant, and can fluctuate with factors such as gender, age, day and night, exercise, and mood changes, but this change is often within the normal range.

Best room temperature for sleeping: 20

If the room temperature is higher than 24, sleep will be lighter and the number of turnovers will increase; The room temperature is below 18, and it is not easy for people to fall asleep.

Suggestion: It is difficult to maintain a constant room temperature, but the room temperature should be as low as possible in winter and 25 to 27 degrees in summer.

The temperature of the gas in the atmosphere is air temperature, which is a common term used in meteorology. It is directly affected by sunlight: the more sunlight, the higher the temperature. China is expressed in Celsius ( ). The surface air temperature referred to by the meteorological department refers to the temperature in the louver box at about the height of the ground.

The optimal temperature for the human body is 19-24.

Comfort temperature refers to the equivalent temperature at which an environment meets the comfort requirements under the conditions of a given amount of human activity, clothing thermal resistance and ambient temperature, that is, the temperature at which the human body feels the most comfortable.

According to experiments at home and abroad, the most comfortable temperature for people is 19-24 in summer and 17-22 in winter. The human body must always keep its body temperature constant. People feel hot when the ambient temperature exceeds the upper limit of the comfortable temperature, and when it exceeds 37, they feel very hot, and the upper limit of the temperature that the average person can tolerate is 52.

On the contrary, when the ambient temperature is below the lower limit of the comfortable temperature, the person feels cold and cold; If it is below 0, it will be cold. For people who are generally well-dressed for outdoor activities, the lower limit of the temperature they can tolerate is about minus 34.

The comfortable temperature is 18 to 25.

When the ambient temperature is between 18 and 25 and the relative humidity is 40 to 70 percent, the human body feels the most comfortable; When the temperature is between 26 and 30 and the humidity is less than 60%, the human body feels hot but not stuffy; When the temperature is higher than 30 and the humidity is greater than 70%, the human body feels stuffy.

In rooms below 18, the human body will feel cold; In rooms above 26, the human body will feel hot. This is also the reason why the minimum indoor temperature of central heating in the north is not less than 18, and it is recommended that the temperature of the air-conditioned room in summer is not less than 26 (the choice of both power saving and human comfort).

The best comfort of the human body is related to altitude and latitude. We usually think that 22 to 23 is the best comfortable temperature for the human body in the middle and low latitude plains, but for Harbin people who have lived in high latitudes for a long time, they will feel that this ambient temperature is a little hotter; Similarly, for Lhasa residents who have lived at high altitudes for a long time, they can also feel a little on the hot side.

In the winter in the north, if the indoor temperature is too high for a long time, it will affect the body's thermoregulation function, causing body temperature to rise, vasodilation, pulse to speed up, heart rate to accelerate, people will be tired, dizzy, slow thinking, poor memory. At the same time, if the temperature difference between indoor and outdoor is too large, the people living in it are also prone to colds and flu.

If the indoor temperature is too low, it will reduce the metabolic function of the human body, constrict the subcutaneous blood vessels, weaken the resistance of the respiratory mucosa, and easily induce respiratory and circulatory diseases. This is best illustrated by the significant increase in respiratory and circulatory diseases among middle-aged and elderly people after the heating is turned off every spring.

Indoor temperature standards and testing.

In fact, since the official implementation of the "Indoor Air Quality Standards" in 2003, indoor temperature has become an important part of indoor air quality. The standard clearly stipulates that the standard value of the indoor temperature of the air-conditioned room in summer is 22 28, and the standard value of the indoor temperature during heating in winter is 16 24. An indoor temperature that reaches this standard is a comfortable indoor temperature.

For the selection of indoor temperature testing and testing institutions, you can find a qualified indoor environment testing unit certified and accredited by the State Quality Supervision Bureau and the Accreditation Commission for testing, and issue a test report stamped with the "CMA" seal, which has legal effect. In the past, people were accustomed to manage and control the indoor ambient temperature through the administrative department, after the release of the national "indoor air quality standards", consumers can use the national standards to maintain their indoor temperature rights, and at present, some areas in northern China have taken the winter indoor temperature as the content of protecting the rights and interests of consumers.

The right indoor temperature is good for human health.

Indoor temperature is an important factor affecting the productivity of personnel, which directly affects the job satisfaction and completion of work.

It is now the summer high temperature season, in order to ensure people's health and work efficiency, and at the same time to maximize energy saving, experts recommend the use of "** temperature", that is, about 27. Because people feel the most comfortable at this temperature, and it is also more energy-efficient, it is called "** temperature". If the air conditioner is turned on very cold, the indoor temperature is too low, which is not only not conducive to people's health, but also wastes a lot of valuable power resources.

In addition, the high relative humidity in the air in summer will also be uncomfortable, when the indoor temperature is higher than 30, the relative humidity is greater than 80%, the ambient temperature is higher than the body surface temperature, the human body temperature rises quickly, and the human body temperature regulation system is in a high load state. It is easy to cause changes in circulation, digestion, urinary and nervous system functions, and then induce heat stroke, ** disease and other fevers; At the same time, the morbidity and mortality of cardiovascular and cerebrovascular and diabetic patients will increase.

Similarly, the indoor temperature should not be too high in winter. In winter, it is very cold outside, and people want to be warmer at home to protect against the cold air. However, heating is not the higher the temperature, the better, the indoor temperature should not be too high, the national standard is 16 24.

Generally, it is advisable to keep the indoor temperature between 20 and 24 degrees, and it is best not to exceed 28 degrees. If you have any questions about indoor temperature, you can also go to the indoor environmental monitoring center for consultation.

Generally speaking, the most comfortable temperature for the human body in the room is 15-18, if the indoor air is not circulated or the relative humidity is less than 35, and the indoor temperature is more than 25, the human body begins to absorb heat from the outside world, you will have a feeling of heat. If the temperature exceeds 35, then the body's sweat glands begin to activate, through a slight sweat to accumulate body temperature, the heartbeat accelerates, blood circulation accelerates, you will feel dizzy, general discomfort and fatigue, drowsiness, and the heat is unbearable. On the contrary, when the temperature drops below 4, you will feel cold.

When the room temperature is between 8 and 18, the human body will dissipate heat to the outside world, and the indoor breeze is blowing, and the indoor relative humidity is between 40 and 60, and you will feel comfortable and healthy. The effect of humidity on the human body is less noticeable in the comfortable temperature range of the room. But when the relative humidity reaches 28 and the relative humidity reaches 90, you will have the feeling of temperature reaching 34.

This is because when the humidity is high, the water vapor content in the air is high, the amount of evaporation is low, and the large amount of sweat excreted by the human body is difficult to evaporate, and the heat in the body cannot be dissipated freely, so you will feel stuffy. Only from the relative humidity, the most suitable air relative humidity for the human body is 40 -50, because in this humidity range the bacteria in the air have the shortest lifespan, the human body will feel comfortable, even and normal breathing. According to the statistics of meteorological experts, when the relative humidity reaches 30, the temperature of heat stroke is 38, when the relative humidity reaches 80 and the temperature is 31, people with weak physique sometimes cause heat stroke, if they encounter low temperature and high humidity in winter, people will feel damp and cold.

A healthy humidity environment is 45% to 65%, and under such humidity conditions, the human body feels the most comfortable, and various germs are not easy to spread. Humidity above 65% will cause discomfort to the human respiratory system and mucous membranes, and reduce immunity. Then you pick 16.

There are differences in body temperature in all parts of the human body, in the morning and evening, and between men and women. There is a relatively stable range of normal body temperature, but it is not constant. In a normal person, the oral temperature (also known as oral temperature) is lower than the axillary temperature and the rectal temperature (also known as anal temperature) is higher than the oral temperature.

During the day, the temperature is lowest at 2 5 a.m. and highest at 5 7 p.m., but the temperature difference should be less than 1 in a day. In addition, women's body temperature is generally higher than that of men. A woman's body temperature also changes slightly during menstruation.

In a healthy state, such as eating normally and dressing appropriately, the body temperature of the human body is generally relatively constant, that is, it is kept around 37 (roughly between, and does not change due to changes in the temperature of the external environment. "**Temperature" - the most comfortable temperature, is about 27.
