Commonly used silver thermometers
What is normal body temperature?This question is difficult to answer than you think.In fact, there is no exact "normal" body temperature.The body temperature is constantly fluctuating within a day of daily life, and everyone has "their own normal body temperature".
The normal body temperature of the human body usually refers to the heat generated by the internal metabolic rate of the human body under a quiet state and the temperature in the balance of in vitro heat, generally between 36.5-37.5 ° C.The normal body temperature of this range is different due to the influence of many factors such as age, gender, body structure, work rest time, and environment.
The normal body temperature of the human body is determined by the control of the body temperature center of the hypothalamus. It is a very precise physiological regulatory system.When the body temperature is too high, the central nervous system can be emitted through the skin by regulating blood vessel dilation and sweating to achieve the effect of cooling; when the body temperature is too low, it will increase the blood vessels and muscle tremor to increase it.The occurrence of heat, thereby increased body temperature.
In some special cases, the normal body temperature of the human body may change.For example, women will increase slightly in the ovulation and menstrual period; in the late pregnancy and lactation period, women’s body temperature will also increase.In addition, diseases and infections can also affect the body temperature of the human body. Some infectious diseases, such as influenza, pneumonia, etc., can cause the body temperature to rise, and certain diseases such as hyperthyroidism can cause increased or decreased body temperature.Newborn (0-28 days): The average body temperature is 36.5-38.0 ° C. Infant (1 month to 1 year): the average body temperature is 36.4-38.0 ° C. Children (1 year old to 3): the average body temperature is 36.1-37.8.8℃. Primary school students (4 to 12 years old): The average body temperature is 36.1-37.8 ° C. Youth (13 to 18 years old): the average body temperature is 36.1-37.5 ° C. Adults (19 to 65): The average body temperature is 36.1 is 36.1 is 36.1-37.2 ℃. Elderly (over 65 years old): The average body temperature is 35.8-36.8 ℃.
The influence of gender on normal body temperature is very small, and the average body temperature of men and women generally differs less than 0.5 ° C.
Oral measuring body temperature
There are many ways to measure normal body temperature. Commonly include oral measurement, anal measurement, underarms, and forehead measurement.Among them, oral measurement is the most commonly used method.Generally speaking, within an hour after getting up in the morning, the body temperature will be slightly lower than the normal level, and the maximum temperature in the afternoon reaches its peak.At the same time, factors such as diet, exercise, and diseases will also affect the measurement results of normal body temperature, so it is necessary to pay attention to the effects of these factors on body temperature measurement.
There are many ways to measure body temperature. The following are the most common methods:
Oral temperature measurement: Put the thermometer (mercury) into the mouth, keep the lips closed and bite the thermometer, and wait a few minutes to read the body temperature.This is one of the most common methods, but it is not applicable for people with bad breath or oral problems in children.
Axillary temperature measurement: Put the thermometer (mercury) under the armpits so that it is tightly put on the skin and wait for a few minutes to read the body temperature.This method is easier to operate more than the temperature measurement of the oral cavity, and the measuring body temperature is more accurate.
Ear canal temperature: Put the thermometer (electronic) into the ear canal and wait for a few seconds to read the body temperature.This method is faster and non -contact than the oral and armpits, and it may not be accurate.
Prefilleration Temperature measurement: Put the thermometer (electronic) at the forehead, no need to close the skin, wait a few seconds to read the body temperature.But because this method may not be exposed to the skin, it may be relatively not accurate.
For adults, the temperature measurement of mild oral measurement is the most commonly used method, and for children, anal temperature measurement may be the most accurate method.In fact, no matter which method is adopted, accurate and reliable thermometers should be used and operated in accordance with the instructions of the use.
It should be noted that if you feel fever or abnormal body temperature, it is recommended to rest for 10-15 minutes before measurement to avoid factors that may affect body temperature.In addition, it is recommended to choose the same time and the same formula for measurement to more accurately track changes in body temperature.
When you are sick, your body temperature will rise and accompany a headache
The rise in human body temperature is a physiological reaction of the body’s factors such as external stimuli, internal metabolism and disease.Here are some reasons that may lead to increased body temperature:
Infection: When the human body is infected with germs, the immune system will resist the germs by generating inflammation and high body temperature.Infectious diseases such as flu, pneumonia, and urinary tract infection usually cause body temperature to rise.
Physical exercise: During physical exercise, muscle metabolism can generate heat and cause body temperature to rise.In exercise, it will also increase physiological reactions such as heartbeat, breathing and metabolism, and promote the increase in body temperature.
Heat environment: Under high temperature environment, the difficulty of heat dissipation in the human body increases, resulting in an increase in body temperature.In addition, high temperature environments may also cause problems such as dehydration and electrolyte imbalance.
Drugs or toxins: Some drugs or toxins can interfere with the metabolic and calorie regulation mechanism in the body, causing the body temperature to rise.For example, some antibiotics, antiepileptic drugs, and anesthesia may lead to increased body temperature.
Hypertrophy of thyroidism: Hypertrophy of thyroid function is an excessive secretion of thyroid gland, which can cause increased body temperature and increase metabolic rate.
In general, rising body temperature is a normal physiological reaction of the body to factors such as external stimuli and internal metabolism.However, if you continue to be high or other symptoms, you should seek medical treatment in time.
Low body temperature is not always good, which may indicate a problem with the body.The normal body temperature range is 36.1-37.2 ° C. If the body temperature is lower than 36 ° C, the following problems may occur:
Decrease in immunity: Human immunity is usually the best operation at normal body temperature. If the body temperature is too low, it may cause immunity to decrease, thereby increasing the risk of infection.
Slow metabolism: Low body temperature may lead to slow metabolism, which may cause symptoms such as indigestion, fatigue, palpitations, dizziness and other symptoms.
Frozen: If the body is exposed to a cold environment, the low body temperature may cause skin damage to the skin and tissue, and may even cause severe frostbite.
Nutrition: Low body temperature may be caused by malnutrition, and malnutrition may lead to decreased immunity, anemia, and other health problems.
Diseases: certain diseases may also cause lower body temperature, such as hypothyroidism, liver disease, infection and anemia.
However, some people have low body temperature, but their bodies operate normally, and they do not have any diseases or discomfort.If your body temperature is always low, but your body has no other symptoms, you may not need to worry about it.But if the body temperature is lower than the normal range and is accompanied by other symptoms, go to the hospital immediately.
Determine that the body’s fever is not caused by the need to perform corresponding testing and diagnosis caused by the new crown virus, because the symptoms of the new coronal virus infection are similar to other virus infections, including fever, cough, fatigue, and shortness of breath.Essence
Here are some conventional measures to help determine whether the body’s fever is related to the new crown virus:
Observation symptoms: In addition to fever, new coronal virus infections are often accompanied by symptoms such as cough, fatigue, shortness of breath, headache, muscle or joint pain.If you have one of the above symptoms, you should consider testing the new coronal virus.
History of contact: If you have the history of contact with patients with confirmation or suspected new coronal virus, you should consider testing the new coronal virus.
Confirm diagnosis: If you have symptoms such as fever, it is recommended to seek medical treatment in time, accept professional medical examinations and diagnosis, and confirm whether it is a new coronal virus infection or other diseases.
Prevention measures: For public health considerations, during the epidemic period, everyone should abide by the prevention measures of the local public health department, such as diligently wash hands, wearing masks, and maintaining social distances to reduce the spread of new crown viruses.
In short, if you have symptoms such as fever, you should seek medical treatment in time and receive professional medical examinations and diagnosis to determine whether you have infected the new crown virus.At the same time, everyone should also take preventive measures to reduce the spread of new coronal viruses.
In general, the normal body temperature of the human body is a very complicated physiological indicator, which is affected by many factors.Pay attention to the measurement method and environmental factors when performing body temperature measurement, and comprehensively evaluate combined with other body indicators and symptoms to understand the health of the body.If you feel abnormal body temperature or other health problems, please seek medical treatment in time.
