What is the reason why a person s normal body temperature varies throughout the day?

It is true that people's body temperature will vary from time to day of day, and the main reason for this is the metabolic status and the environment in which they are located, and the temperature is also related to certain factors. The temperature will be different in different seasons throughout the year, and the body temperature will be different in different seasons, so the environment in which a person is located also affects the change of a person's body temperature. For example, in a hot temperature, a person's body temperature may rise slightly, and in a cooler area, a person's body temperature may drop, but a person's normal body temperature is mostly maintained between 36 and 37 degrees, and the temperature change will not be particularly large.

The hotter the weather, the more vigorous the metabolism, the energy will be consumed a lot, the natural body temperature will also rise, the weather is cold, the person's metabolism will be slower, and the body temperature will also decrease. <>

Usually when we play basketball and do intense exercise, then it is easy to sweat, and the body temperature is easy to rise at this time. Whether it's playing basketball or running, it will increase our metabolism and put our body in a state of heat, in which case, the body temperature will rise. When we stop exercising and sweat a lot, the pores will open, and the body temperature will drop, which is also a normal phenomenon.

A person's body temperature tends to drop to its lowest while sleeping。Because the various functions and cells and organs of the human body have to enter a semi-resting state when sleeping, whether it is metabolism or energy consumption, they have reached the lowest value of the day, so the temperature at this moment is often low. Sometimes a person doesn't feel cold when he sits, but once he falls asleep, he feels cold is such a reason, after all, all organs of the human body need to rest when sleeping.

Generally speaking, the body temperature in the morning is not particularly high, because after a night's rest, when you wake up on the second day, the rate of metabolism is relatively slow, and it takes a while to return to normal, so the body temperature in the morning is often low。There will be different changes in body temperature at different times, and we should increase or decrease clothing according to the body temperature condition.

The reason for the difference is that the surrounding temperature is also different within a day, so people's body temperature will be adjusted according to the surrounding links, so it will be different.

It is because a normal person will do different things in a day, from the time he gets up in the morning to the time he falls asleep at night, he will carry out different activities and go to different environments, so the body temperature is also different.

Because the body surface temperature of the human body changes with the influence of the outside temperature, as long as the body temperature is within the normal value, there is no need to worry about it being a normal phenomenon.

A person's normal body temperature changes with the ambient temperature. The internal organs of the human body will regulate, through various ways such as sweating, exhalation, etc., to regulate the internal and external environmental temperature, the body temperature is kept at about a degree, and there is a little change up and down in a day, but the change is not much.

In the morning or early morning, the human body gradually becomes active from static to dynamic, waking up from sleep. In the fasting state, the body temperature is lowest when not exercising.

In the afternoon, after lunch, the body temperature is at its highest at about 4-5 o'clock. Nonetheless, body temperature fluctuations range within 1, which is a physiological change in body temperature normal.

The changes in body temperature in a day are related to the peaks and troughs of hormone secretion in the human body and the normal physiological activities of the human body, and the hormones that can regulate the body temperature of the human body are common thyroxine and adrenocortical hormones. The secretion level of the two hormones is lowest in the early morning and highest in the afternoon, which is not the basis for the low body temperature in the morning and high in the afternoon.

A person's normal body temperature will be different throughout the day, and it is also related to the amount of exercise and food eaten in a day. Eating, moving, whether physical or mental, will raise the body temperature, so the human body temperature is not constant, but slightly fluctuating.

The temperature of the human body also undergoes periodic changes throughout the day, and the main reason for the change is that the rate of metabolism, blood circulation and breathing intensity will change periodically throughout the day, so that the production and release of energy will also change regularly, which is manifested in the periodic nuances of body temperature.

For example, from early morning to 4 o'clock is the time for human sleep, especially deep sleep, metabolism, blood circulation and breathing speed are the lowest, and the body temperature is also the lowest, and the temperature of the human body reaches its peak before and after dinner, at this time the human body activity is relatively high, and the heat accumulation also reaches its peak, but the difference between the highest temperature and the lowest temperature of the human body in a day generally does not exceed 1 degree. At the same time, the temperature of different parts of the human body is also different. For example, the temperature of the head is the highest, followed by the chest and waist, and the limbs again, and the temperature of the hands and feet is the lowest.

Whereas, among the internal organs, the temperature is highest in the liver and the lowest in the rectum. Our body's ** temperature regulation is the strongest, and its temperature range can span a large range of 20 to 40 degrees, allowing us to better adapt to changes in our surroundings.

The body's temperature fluctuates throughout the day, and the body constantly tries to heat or cool itself to ensure that the temperature stays around 37. The human body works most efficiently at the left and right temperatures. The process of metabolism is used to produce heat in the body.

Thermogenic is actually *** of the metabolic process itself. This heat is then transferred around the body in the bloodstream, which is also used as a thermoregulator. When the body needs to dissipate heat, the blood vessels dilate and blood flows to the limbs of the body, from where the heat is dissipated.

The body temperature of normal people fluctuates at 36-37 degrees Celsius, and the fluctuation of body temperature is slightly higher in the morning, and generally higher in the morning than in the afternoon and evening; If you exercise vigorously or after eating, your body temperature can also rise; Pregnancy or premenstruation, elderly women or patients with hyperthyroidism generally have higher temperatures; The basal metabolic rate of the elderly is relatively low, and the general body temperature is relatively low. In addition, if the weather is relatively warm, the body temperature rises slightly; If the temperature is relatively low in the cold winter, the body temperature can change slightly.

During the day and night, the body temperature is lowest between 2 and 6 in the morning and highest in the afternoon between 1 and 6 o'clock. This circadian cyclical fluctuation in body temperature is called a circadian rhythm or diurnal cycle. In addition, emotional agitation, nervousness, eating and other conditions will have an impact on body temperature; Changes in ambient temperature also have an effect on body temperature.

Therefore, the body temperature measured at different times of the day will vary.

Human body temperature does fluctuate several times in a day, which is related to factors such as metabolic status, temperature and environment at different times of the day.

A person's normal body temperature is generally maintained at around 36-37, and unless there is a high fever, it will reach 38 or even higher.

After a night's sleep, the whole human body is resting, the metabolism is relatively slow, and after getting up, it takes a while to return to normal, so the body temperature in the morning is the lowest time of the day.

Some people who like to stay up late wake up late in the morning, and when it's time to eat, they don't have any appetite at all, and that's the reason. The body has not yet moved, and the human tissues and organs are still in a state of slackness, so they naturally have no appetite.

After a morning of study, work and activities, all the cells and tissues of the human body have been fully mobilized and entered a relatively active state, and the body temperature is also relatively high during the day.

When a person has a fever, it is also more obvious at night.

At night, after the person goes to sleep, the body temperature reaches its lowest value.

During sleep, the human body is in a resting metabolic state, cells, tissues, and organs are in a semi-resting state, the metabolism slows down, less energy is consumed, and the body temperature reaches the lowest value of the day.

Body temperature is greatly affected by the intensity of work and the degree of physical labor, when people are engaged in physical labor, they need to consume more energy, and these consumed energy is converted into heat energy and released, and the body temperature will be relatively high.

Most of the mental workers are sedentary at their desks, their consumption is small, and the change in body temperature is not as large as that during physical labor, and the temperature is relatively low.

Body temperature can also change due to environmental factors.

In winter, the weather is cold, the temperature is low, the metabolism of the human body is slow, and the body temperature of the person is also low; In summer, the weather is hot, the temperature is high, the metabolism of the human body is vigorous, the energy is consumed a lot, and the body temperature is relatively high when it is serious.

A person's normal body temperature varies throughout the day. ......A person's body temperature will vary depending on the time period.

Specifically, the body's body temperature varies from time to time of day.

Specifically: around six o'clock in the morning, the body's body temperature is at its lowest.

Around two o'clock in the afternoon, the body temperature of the human body is at its highest.

Such a state of body temperature corresponds to the state of the human body.

Specifically, there are the following correspondences between the two:

1. When we are at rest, our body temperature drops.

2. When we are in a state of exercise, the body temperature rises.

This illustrates a problem: our body temperature corresponds to the state of our body.

In addition, there is another correspondence between our body temperature and our physical state:

1. When our body temperature drops, we are in a state of rest.

2. When our body temperature rises, we are in motion.

This correspondence shows that changes in our body temperature are required for the state of our body.

It is precisely because of the above reasons that our body temperature has different body temperature values at different times of the day.

And it is precisely because our body has this ability to regulate that we will have the ability to adapt to various environments, allowing us to survive and thrive better.

It should be noted that although our body temperature will change constantly throughout the day, the specific change value is not very large. ......The value of the change in our daily body temperature, the difference between the highest and the lowest value does not exceed the degree Celsius.

The body temperature of a normal person changes in a day, 6 o'clock in the morning is the lowest point of body temperature, 4-6 o'clock in the afternoon is the highest point of body temperature, and the difference between the highest point and the lowest point of body temperature is generally not exceeded. If it is exceeded, it can be considered a fever, and it is necessary to clarify the ** of the fever.

In addition to the time of change, the body temperature changes after exercise, after eating, and after taking a hot bath. This change can also be more than 1, so for a normal person, the body temperature of a day can change with the change of the external environment, the amount of exercise, and the time. In addition, for women's special periods such as ovulation and pregnancy, the body temperature during this period is also higher than the usual body temperature, and the body temperature can also be above 37.

Therefore, the body temperature of a normal person actually fluctuates, but this fluctuation range cannot be exceeded.

For example, in the morning, our body temperature is relatively low, because the body function is still inactive in the morning, and the blood circulation is relatively slow, at this time, the body temperature is relatively low, when the body begins to participate in work or work during the day, the body function is active, the blood circulation is accelerated, and all cells are working, and the body temperature will naturally rise, so through these two points, There are some temperature differences in body temperature according to the activity of the human body, which means that the body temperature of the human body will be different in different times of the day and in different states.

Normally, the fluctuation of body temperature in a 24-hour period does not exceed 1, with the lowest temperature at 2 6 in the morning and the highest at 1 6 in the afternoon.

There are slight differences in body temperature in different physiological states, and children can have a slightly higher body temperature than normal people due to their high metabolic rate. Older people have a lower body temperature than younger adults because of their metabolism slowing down. Women's menstrual body temperature is lower than usual, and slightly higher during ovulation and pregnancy.

In addition, factors such as eating, strenuous exercise, sudden entry into a hot environment, and emotional agitation can also cause a slight increase in body temperature.

Normal human body temperature is regulated by the body temperature regulation center through nervous and humoral factors to regulate the process of heat production and heat dissipation, and maintain dynamic balance, so the human body maintains a relatively constant body temperature.

The main reason why people's body temperature varies from day to day is that there are some changes in temperature throughout the day, and there will be some changes in the metabolic cycle within the body, so there are certain differences in body temperature, but the difference between their values is not particularly large. As long as the body remains stationary for more than 5 minutes, the measured body temperature value is relatively accurate. The body temperature measured after exercise is not particularly accurate, so it is necessary to look at the current physical condition when measuring the body temperature.

The normal person's body temperature is between 36 and 37, which generally refers to the temperature under the armpits, the body temperature will be slightly lower in the morning, the body temperature will be slightly higher in the afternoon, the body temperature will be lower when it is quiet, and the body temperature will be higher after strenuous activities or emotional excitement. At the same time, the body temperature of the elderly will be relatively low, but the temperature will not differ by about one degree Celsius a day, women in the ovulation period or in the early stage of pregnancy, sometimes lead to an increase in body temperature, but generally not more than about one, usually to monitor the body temperature at any time, if the body temperature exceeds, this situation is an abnormal situation, you can go to the hospital for examination and **.
