When a person sleeps, the body temperature generally drops to a few degrees

Hello: The temperature of the oral cavity (under the tongue) is degrees when the person's body temperature is normal. The underarm temperature is degrees. The temperature inside the rectum (anal temperature) is degrees.

During the day and night, the normal body temperature is the lowest in early morning sleep, rising sharply from 7 to 9 o'clock in the morning, and then slowly rising, reaching the highest value at 17-19 o'clock in the afternoon, and then declining, reaching the lowest stable value at 23-24 o'clock in the evening. The difference between the highest and lowest values, usually between 1 degree.

In general, women's body temperature is slightly higher than that of men of the same age, and women have a higher body temperature before menstruation and menstruation.

The body temperature usually decreases by about a degree, usually by the time of ovulation, and then rises suddenly.

The body temperature of a normal person fluctuates from day to day, and the fluctuation of body temperature in adult women is also related to the menstrual cycle.

Relate. A woman's basal body temperature during the menstrual cycle, before ovulation.

It is usually low, and the normal body temperature before waking up in the morning (i.e., basal body temperature) is below 37 degrees, about about one degree. After ovulation, the average rise is around and continues until the onset of menstruation.

Hello, I think there are two reasons for this. External environmental factors and physical factors.

The lowest temperature of the day is in the early hours of the morning. The weather forecast by the Meteorological Observatory always reports a maximum temperature and a minimum temperature. We all have the experience that on a sunny day in summer, the hottest time is not at noon, but at two or three o'clock in the afternoon.

The lowest temperature is in the early hours of the morning.

The heat and cold of the weather are mainly determined by the air temperature, and the main factor affecting the air temperature is determined by the intensity of solar radiation. However, solar heat is not the main reason for the direct increase in temperature. In total, only about 14 of the heat energy directly absorbed by the air into the sunlight is absorbed by the ground, and about 43 is absorbed by the ground.

After the ground absorbs the radiant heat of the sun, it is transmitted to the air through radiation, convection, etc., which is the main reason for the increase in temperature.

When the sunlight hits the ground, it heats the ground, and the heat absorbed by the ground is released to dry the air, so after the ground is heated, it will take a while to make the temperature rise. At noon. Hello, I think there are two reasons for this. External environmental factors and physical factors.

When the sunlight hits the ground, it heats the ground, and the heat absorbed by the ground is released to dry the air, so after the ground is heated, it will take a while to make the temperature rise. After noon, the heat emitted by the ground is still less than the heat supplied by the sun until the afternoon.

At two or three o'clock, the ground temperature can rise to the highest, and the temperature is the highest.

In the same way, after the sun goes down, it loses the heat of the sun, therefore, it begins to lose heat continuously, and the airflow continues to decrease, and in the early morning, the ground temperature drops to the lowest value, so the temperature is the lowest at this time.

During the day and night, normal body temperature is lowest in early morning sleep. The human body can maintain a certain temperature because the blood flows in the human body, carrying a certain amount of heat, which can ensure that every part of the body can be maintained at a certain temperature. When people sleep, because the human body enters a dormant state, the work speed of some organs slows down, and the speed of blood flow also slows down, and the temperature of the human body will decrease with the slowdown of blood flow and the speed of heat supply, so the body temperature of people when they sleep is lower than when they are awake.

Generally, the temperature difference between day and night (normal body temperature, not abnormal body temperature) does not exceed 1 degree Celsius.

Hope mine is helpful to you.

No. Eliminate tomatoes.

The body temperature of healthy people is relatively constant, and under the action of internal and external factors, the body temperature can change slightly within the normal range, for example: the body temperature in the afternoon is relatively higher than that in the morning, but the difference is generally less than 1;

Body temperature may also rise slightly after eating, labor, or strenuous exercise; Factors such as sudden entry into a hot environment or emotional agitation can also cause a slight increase in body temperature; Women have a slightly higher temperature than normal during ovulation and pregnancy. There are also slight differences in body temperature at different ages, such as children with higher body temperature than adults due to high metabolic rate; Due to the low metabolic rate of the elderly, their body temperature is also slightly lower than that of young adults.

It depends on the weather, if it's a hot day, the temperature on your body will generally remain the same when you sleep, and it will increase unabated. If it's a cold winter, you cover the quilt, the body is a hot body, and the temperature of the body spreads to the quilt, and the temperature of the body will not drop, which is why you have to cover the quilt when it's cold. If your quilt can't be warm or too thin, then the temperature on your body will drop by about 3 or 4 degrees, and the temperature of your feet will be relatively lower!

People often confuse body temperature with hot and cold sensations in their daily lives. Body temperature is an objective indicator of the basic characteristics of the human body, while hot and cold is a feeling of human beings, which is highly subjective. It is often said that the perceived temperature is based on life experience, and the actual temperature is measured by an instrument in a certain way.

In the same temperature environment, some people feel cold and some people feel hot, which is the truth - temperature and hot and cold are two different things. When you feel hot, it doesn't necessarily mean that you have a high body temperature (it could be, for example, a fever, but a fever can sometimes feel cold. This can also be used as an example.

Talking about the problem of human body temperature.

The body temperature of the human body refers to the temperature in the human body, and the fluctuation range is small. The closest temperature to the body can be directly measured is the rectal temperature, which is the anal temperature. The body temperature of the human body fluctuates slightly throughout the day, and the basal body temperature is generally measured, that is, the body temperature of the person when he is quiet, lying still, because it is obvious that the body temperature of the person rises during strenuous exercise.

When a person wakes up in the morning (before getting up to exercise), the basal body temperature at this time is low, not high. When you say high body temperature, it's probably because you feel hot, not really high body temperature.

The body temperature begins to rise slightly during the day after waking up in the morning, with two high peaks, one around 10 a.m. and one at 4-5 p.m., after which the body temperature gradually decreases and is lowest in the early morning. The normal fluctuation of internal temperature is generally not more than 1 degree.

。Because when people sleep, unless they are in deep sleep, their body temperature is higher than normal at other times. In the lying state, the load on the internal organs of the body is relatively large, and the temperature control nerve in the human brain stem will turn into a periodic reflex, so when people first get up in the morning, the body temperature will be about higher than normal.

will fall, and the fluctuation of diurnal body temperature does not exceed 1 degree Celsius!

Hehe, friends, we know that the body temperature of the human body is relatively constant, but it is not immutable, it is within the normal range, affected by a variety of factors, and has a certain normal fluctuation range. Compared with the morning and afternoon temperatures of normal people, the afternoon is generally 0 17 (axillary temperature) and 0 12 (oral temperature) higher than the morning, but there are also people who have a lower body temperature in the afternoon than in the morning.

Another example is the change of day and night, the temperature of day and night can have periodic changes, between a day and night, the lowest in the early morning at 0 4 o'clock, from 7 to 9 o'clock sharply, and then slowly rise, to 17 19 o'clock to reach the highest value, and then decrease, to 23 24 is to reach a stable value. There can be three peaks in body temperature during the day.

The first and second peaks occurred about one hour after breakfast and lunch, respectively, and the third peak occurred after 5 p.m. Among them, the third high peak is the highest, and the difference between the highest value and the lowest value is often within 1.

Human body temperature is controlled by the hypothalamic thermoregulatory center. Cellular metabolism produces heat, and during the day, in addition to maintaining basic metabolism such as heartbeat and blood circulation, it is also necessary to maintain the needs of eating and other activities, so it needs more energy during the day, and the body produces more heat, and the body temperature will be higher.

At night, when the body's activities are almost complete, and while sleeping, the body's metabolism slows down, the number and intensity of heartbeat and breathing decrease, and the body temperature drops.

It is generally believed that this cyclical change depends mainly on the internal causes of the organism, which is determined by the internal regularity formed by the lifestyle and habits of generations. Its changes may be related to cyclical changes in the body's diurnal activity and quiet rhythmic, metabolic, blood circulation, and respiratory function. In addition, external conditions also have an impact on the cyclical temperature of day and night, for example, people who work night shifts for a long time may have a different periodic fluctuation of body temperature than the general population, and may have a nocturnal increase in body temperature and a decrease in daytime body temperature.

Therefore, the body temperature does not rise when sleeping, but it is not ventilated in the quilt at night, and the heat gathers together, creating the illusion of an increase in body temperature. During the day, the heat is dissipated through the gas, and it feels as if the body temperature is a little lower, but in fact the normal body temperature does not change. It is only in the early stages of pregnancy that a woman's basal body temperature rises a little.

From what I know, a person's body temperature is lowest around 2 a.m., so after falling asleep, a person's body temperature decreases first and then rises. This is what I learned about biology (o).

Skin temperature should be lowered.

When people sleep, because the human body enters a dormant state, the work speed of some organs slows down, and the speed of blood flow also slows down, and the temperature of the human body will decrease with the slowdown of blood flow and the speed of heat supply, so the body temperature of people when they sleep is lower than when they are awake.
