Will the body temperature drop in the afternoon? Why does the body temperature rise in the afternoon

When a person's body temperature is normal, the temperature in the mouth (under the tongue) is degrees. 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, the body temperature of women is slightly higher than that of men of the same age, and the body temperature of women is higher before menstruation, and the body temperature drops about a degree at the onset of menstruation, and then decreases again when ovulation occurs, 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. During the menstrual cycle, the basal body temperature before ovulation is often low, and the normal body temperature before waking up every morning (i.e., basal body temperature) is below 37 degrees, about about a degree. After ovulation, the average rise is around and continues until the onset of menstruation.

Yes, a person's body temperature changes slightly throughout the day, but it can vary greatly for people who are sick, for example, they have a normal body temperature in the morning and a terrible fever in the middle of the day.

In the afternoon, people's body temperature is supposed to rise, because the highest temperature in the day is between 12 and 2 o'clock, the outside temperature rises and the person's thermoregulation center will of course have to make a certain response, and the temperature of the external environment will rise accordingly, and our body temperature will rise accordingly in summer

Under normal circumstances, a person's body temperature shows a certain diurnal variation, that is, the body temperature will fluctuate many times throughout the day. In general, the body temperature of the human body temperature will rise slightly in the morning and afternoon, and drop slightly in the evening.

The reasons for the increase in body temperature in the afternoon are multifaceted, including:

The impact of digesting food: Afternoon is the time when people usually eat, and digesting food also requires a certain amount of energy, which produces heat and causes body temperature to rise.

It should be noted that an increase in body temperature in the afternoon can also be a manifestation of certain diseases or pathological states. If the body temperature continues to rise, accompanied by other symptoms such as headache, cough, sore throat, etc., it may be a sign of infection or other illness and requires prompt medical attention.

During the day, the temperature is lowest at 2 to 5 in the morning and highest at 5 to 7 in the afternoon, but the temperature difference should be less than during the day.

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. 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 to 5 in the morning and highest at 5 to 7 in the afternoon, but the temperature difference should be less than during the 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. The average normal body temperature of the human body is between 36 and 37 (armpits), beyond this range is fever, below 38 is a low fever, and above 39 is a high fever.

Hello! Basal body temperature, also known as resting body temperature, refers to the body temperature measured after 6-8 hours of sleep, such as waking up from a deep sleep in the morning, and the body temperature has not been affected by exercise, diet or emotional changes. Basal body temperature is usually the lowest body temperature in a human body during the day and night.

This is the reason for the low body temperature in the morning.

The body temperature of the human body is relatively constant, but it is not static, 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.

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.

The normal oral temperature of the human body is, but the body temperature is not constant throughout the day. In general, the body temperature is higher in the afternoon than in the morning, and gradually decreases after 8 p.m., reaching its lowest at 0 4 p.m. And the body temperature varies depending on the season.

For example, the average axillary temperature of children varies with the season, and in spring, autumn and winter, it is in the morning and in the afternoon. In summer, the body temperature is 37 in the morning and 37 in the afternoon. In the afternoon, the body temperature rises above normal body temperature, and this condition is first thought to be caused by a tuberculosis infectious disease.

Because the typical manifestation of tuberculosis is low-grade fever in the afternoon.

So it is advisable to check it out.

This is the case, because the sun just rises in the morning, the temperature cannot rise immediately, and in the afternoon, after the sun shines for a long time, the temperature will naturally rise, so the temperature in the afternoon is higher than in the morning.

It is normal for the metabolism to be more vigorous in the afternoon than in the morning.

Analysis: Implantation body temperature can cause a decrease.

Suggestions: Under normal circumstances, the fertilized egg implants on the 6th-7th day, and the small gestational sac can be seen with B-ultrasound about 20-30 days after implantation. 3-4 days after implantation of the fertilized egg (i.e. after the 10th day after ovulation), a weak positive test can be detected with an early pregnancy test strip.

Women's reproductive hormones are complex and constantly changing, and the basal body temperature fluctuates. The basal body temperature of a normal woman is based on the day of ovulation, showing a state of low before and high at the back, which is the so-called biphasic body temperature. However, there are also many women who have never been able to detect regular changes in body temperature.
