What does the rise in body temperature have to do with it? Under what circumstances does the body temperature rise?

We all know that the new coronavirus is a new virus that broke out at the end of last year. Its infection symptoms are very similar to cold and flu. Fever is one of the most obvious symptoms. Many people will pass their body temperature to conduct inspection and troubleshooting. So under what circumstances will the body temperature rise? Let’s take a closer look below! Under what circumstances will body temperature rise?

Weather, diet, and even menstrual periods, many factors can affect body temperature and make it exceed the normal range.

So if your body temperature is high, don’t panic. Check to see if there are any of the following conditions: 1. If the temperature is high, the body temperature is high, and if the temperature is low, the body temperature is low

Body temperature It will change with the temperature. In a high-temperature environment (such as a heated car), your body temperature may rise slightly. In a low-temperature environment (such as outdoors in winter), your body temperature may rise slightly. reduce.

In these cases, there may be errors in temperature measurement. It will be more accurate to wait in a room temperature environment for a while and then measure again. 2. The body temperature is low in the morning and high in the afternoon

Human body temperature will also change slightly throughout the day.

When you get up in the morning, the body temperature is at a low point. In the afternoon and towards evening, the body temperature is at a high point. The peak difference between the two points is about 0.5℃. 3. High body temperature after exercise and meals

After strenuous exercise, labor or meals, the body temperature may also rise slightly, but the general fluctuation range does not exceed 1 ℃. 4. Infants and young children have high body temperature, while the elderly have low body temperature

Infants and young children usually have a higher body temperature than older children and adults due to their high metabolic rate; elderly people have a lower body temperature than young adults due to their low metabolic rate, so When the elderly are seriously infected, they may only have a low-grade fever. 5. Women’s body temperature is high during ovulation and pregnancy

A woman’s body temperature will rise by approximately 0.6°C during ovulation, and this body temperature level will be maintained until menstruation (so some people also monitor body temperature to predict ovulation).

In addition, changes in hormone levels in the body during pregnancy will also increase body temperature. How to measure body temperature accurately

The correct way to measure body temperature is to first take out the thermometer, gently shake the thermometer twice, and swing the mercury needle inside to the starting position. Then put the mercury thermometer under your armpit, wait five minutes, take out the thermometer, and take the indicated value of the mercury needle. Although the method of measuring body temperature with a mercury needle is simple, you should pay attention to the following details when measuring, otherwise the measurement results will be biased.

First of all, when measuring the temperature, you must not move around and stay calm. When measuring body temperature, if you do not keep calm and keep moving, the probe of the thermometer will easily deviate, causing errors in the measurement results and inaccurate measurement results.

Secondly, measuring body temperature requires multiple measurements. Throughout the day, the body temperature of the human body is constantly fluctuating. The body temperature is the lowest between 2 a.m. and 5 a.m., and the body temperature is the highest between 5 p.m. and 7 p.m. The body temperature will be relatively low when at rest, and will rise slightly after exercise, eating, and mood swings. If your body temperature measured during exercise or other periods is a bit high, exceeding 37.3 degrees, don’t panic. Wait until it calms down for half an hour before taking another test. The thermometer itself may have errors, and the human body's temperature is constantly fluctuating, so the results obtained from multiple measurements will be more accurate. What body temperature is considered a fever?

Generally speaking, according to the level of fever (based on oral measurement), it can be divided into:

Low fever: 37.3-38℃,

Moderate fever is 38.1-39℃,

High fever is 39.1-41℃,

Ultra-high fever is above 41℃.

The normal body temperature of the human body (based on oral measurement) is 36.2-37.2℃. The body temperature in the afternoon will be slightly higher than the body temperature in the morning. The body temperature will also be slightly higher after eating and exercising, but not will exceed 1℃.

For the same person, the temperatures in the mouth, armpits and rectum are different, with the rectal temperature being higher.

Young children: Young children are more likely to have fever because their neurological development is not as complete as adults, and the range of body temperature fluctuations will be larger.

The elderly: The body temperature of the elderly is generally low because their metabolism is relatively slow.

Your body temperature may be slightly higher after eating and exercising. Please rest for at least 30 minutes after eating and exercising before measuring again.

The temperature difference in the environment may also affect the body temperature. It is recommended to stay indoors for 15 minutes before measuring the temperature. Which part of the body is most accurately measured by a handheld infrared body temperature monitor?

In this regard, Feng Luzhao, a researcher at the Chinese Center for Disease Control and Prevention, said that in winter and spring, the temperature is relatively low, and handheld infrared body temperature monitors need to be calibrated before use. Especially when measuring people who enter the room from outside, or when using a measuring instrument outdoors, it is recommended to measure the skin parts covered by clothes or scarves, such as wrists and necks, so that the numbers obtained can be more accurate.
