Why does body temperature fluctuate throughout the day? How much volatility is normal?

Again, 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 ability is the strongest, its temperature range can span 20 40 degrees this large range, so that we are better people are homeothermic animals, body temperature in a day in different parts of the temperature is also different, normal people's oral body temperature is generally degrees, average degrees, armpit temperature is generally 36 ° degrees, average degrees, so the temperature of people is between degrees, are basically normal, sleep at night due to slow blood circulation, usually one degree higher than during the day.

point), the body temperature may be a little lower in the afternoon and evening.

<> (5 to 7 p.m.), the body temperature will be a little higher. While a woman's body temperature may be slightly higher than that of a man, while a woman of childbearing age may have a higher body temperature during ovulation. However, it will not exceed the person's body temperature, and there will indeed be several fluctuations in the time of day, which is related to the metabolic status, temperature and environment of the person at different times of the day.

Age Body temperature varies from age to age due to different levels of basal metabolism. The body temperature of children and adolescents is higher than that of adults, the body temperature of the elderly is lower than that of young adults, and the body temperature of newborns and premature infants is easily affected by the influence of environmental temperature due to the imperfect thermoregulation function.

Because the body's own life activities, as well as day and night, movement is still, sunny and cloudy days have an impact on body temperature, so the body temperature fluctuates within the normal rangeDiurnal variationHumans are homeothermic animals, and the temperature of the body is always constant between degrees Celsius. As long as the body temperature fluctuates within the normal range, there is no problem.

The temperature of the human body fluctuates throughout the day because the body temperature varies depending on the environment in which the body is located and the amount of exercise. Normal fluctuations in human body temperature within a day should be within the range of 1, which is a normal phenomenon. If the temperature fluctuates too much, you should seek medical attention promptly.

Because the body's thermoregulatory center can maintain the body's body temperature fluctuating at a normal level according to changes and changes in the environment, rather than statically. Fluctuations in body temperature in the range of 36 to 37 degrees Celsius are normal.

The body's own body temperature will fluctuate due to environmental or physiological factors, such as eating, emotional agitation, exercise, nervousness, anxiety, etc. In addition, it is also related to the distribution of endocrine hormones, the body temperature is relatively low in the early morning, and the body temperature is relatively high at 4-5 o'clock in the afternoon, but whether the body temperature is low or high, the difference is within 1, and will not exceed 1.

According to relevant studies, the optimal survival temperature of many bioactive enzymes in the human body is about 37 degrees Celsius, and high or too low body temperature will affect the normal activity of these enzymesAs a result, the metabolism is disordered, and the human body will produce diseases, so in the long-term evolutionary processThe temperature of the human body gradually remained in the stable range of 36-37 degrees Celsius (armpit temperature).

The temperature of the human body also undergoes small changes throughout the day, and the reason for the changeThe main reason 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 regularlychemical, manifested in the body temperature has periodic nuances.

The process of metabolism is used to produce heat in the body. Thermogenic is actually *** of the metabolic process itself. These calories are then transferred around the body in the blood, bloodThe liquid 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.

If we are in a high temperature environment, for example, after we exercise,Or our armpits are wrapped very thickly, and the body temperature will be slightly higher than 37 degrees Celsius when we measure our body temperature. As long as we get out of the low or high temperature environment for a while, our body temperature will return to normal body temperature.

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.

Generally, women will have a higher temperature during pregnancy or premenstruation; The basal metabolic rate of older people is relatively low, generally relatively low body temperature. In addition, if the weather is warmer, the body temperature will rise slightly; If the temperature is relatively low in the cold winter, the body temperature can change slightly.

Because the human body is a constant temperature, if there are usual exercises, diets and mood fluctuations, these will easily lead to fluctuations in body temperature, which is a normal physiological phenomenon, and it will be within the normal range of 36 37.

Sometimes, if you can sit quietly, your body temperature will be low, and when you run, your body temperature will rise sharply.

Because people exercise or rest at different times, or the temperature around them changes, the temperature of the human body will also be adjusted, so it will naturally change.

It's normal for your body temperature to fluctuate a little during the day.

If you're measuring armpit temperature.

36 to all are normal.

This is called the circadian rhythm of body temperature.

Temperature is lowest between 2 and 6 a.m.

It is highest between 1 and 6 p.m.

This is determined by the body's internal biological rhythms.

Controlled by the suprachiasmatic nucleus of the hypothalamus.

You didn't say your gender.

Women are taller than men on average.

As for runny nose and dry cough, these symptoms should be caused by the change of seasons.

Pay attention to your diet and keep warm.

Drinking hot water or doing activities that cause a caloric increase will definitely cause the body to cool down.

For example, sweating. A person's body temperature is controlled by a body temperature setting point.

To maintain normal body temperature.

Some heat-generating or heat-dissipating reactions of the body are necessary.

The above data are from the seventh edition of Physiology. Hand hit.

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.

Both humans and higher animals have a certain body temperature. The production of body temperature is the result of the body's constant metabolism. At the same time, body temperature is an important condition for the normal functioning of the body.

With the evolution of animals, the thermoregulation function has become more and more perfect. The body temperature of lower animals changes with the change of ambient temperature and cannot maintain a relatively constant body temperature, so they are called ectotherms. Human and higher animals can maintain the relative stability of the internal environmental temperature and improve the adaptability to changes in the ambient temperature by adjusting the heat production and heat dissipation process in the body under the condition of different ambient temperatures, so they are called homeothermic animals.

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. However, the normal body temperature of the human body does not refer to a specific temperature, but a temperature range. For example, for most normal people, the oral temperature range is between (but only an average), the axillary temperature range, and the rectal temperature range.

Although the body temperature of the human body is relatively constant, there is a certain difference in body temperature between human individuals, and the standard body temperature of a few people can be lower or higher. Even the body temperature of the same person is not exactly the same in a day, and the temperature can fluctuate up to about 1 day and night. Hope.
