How many degrees is normal body temperature, and is fever serious?

It is normal below 37 degrees, if the body has a fever for a long time, it will cause lung infection, and it will also cause symptoms of severe cold and sore throat.

The body temperature of the human body is about 36 degrees Celsius, if you feel a fever, you should take antipyretic medicine in time, and if it is serious, you should go to the hospital in time.

The normal range is between. The temperature of the rectum is in between, slightly warmer than that of the oral cavity. The fever is not severe.

The normal body temperature of a person is 37 degrees Celsius (Fahrenheit, but the temperature varies from part to part, with the highest temperature in the internal organs, followed by the head, and the lowest in the ** and the ends of the limbs. For example, the temperature of the rectum is on average, the temperature of the oral cavity is lower than that of the rectum, and the temperature of the armpit is lower than that of the oral cavity. The body temperature will also fluctuate to a certain extent within 1 day, such as the lowest body temperature at 2 6 o'clock in the morning, gradually rising at 7 9 o'clock in the morning, the highest at 4 7 o'clock in the afternoon, and then decreasing, and the temperature difference between day and night will not exceed 1.

Body temperature is also slightly different in gender and age, for example, females are slightly higher than males; Newborns are slightly higher than children; Young people are slightly higher than older people, and the body temperature of older people is the lowest. In addition, body temperature is also affected by factors such as activity, climate, spirit, eating, etc. In life activities, the human body constantly carries out oxidative metabolism and constantly produces heat; At the same time, body heat is also dissipated into the external environment through heat dissipation pathways (**, blood vessels, sweat glands), and the balance of heat production and heat dissipation keeps the body temperature relatively constant within 1 day.

Fever refers to a person's body temperature exceeding the normal range, when the oral temperature exceeds or the rectal temperature exceeds, and the day and night fluctuations exceed 1. Fever is a systemic defense response of the human body to the child, Sun Xiao is a symptom to be manifested when sick, the cause may be the result of infection (bacteria, viruses, parasites), or tissue damage, inflammation, transplant rejection, malignant disease, secondary consequences of tumors. Sometimes women also have a low-grade fever during menstruation or ovulation.

In general, a thermometer in the United States is considered a fever if it exceeds Fahrenheit.

The United States uses Fahrenheit (f) as the temperature unit, and China uses Celsius (c) as the temperature unit

1、f=c×

2、c=(f-32)÷

Under normal circumstances, a body temperature of more than 37 degrees Celsius is considered a fever, so 37 degrees Celsius translates to 37 degrees Fahrenheit, which is a wild high Fahrenheit.

Extended information: When you have a fever, the body's metabolism accelerates, the decomposition of protein in the body accelerates, and measures to help ** such as drinking more water, urinating more, sweating more, etc., also greatly increase the excretion of B vitamins and vitamin C.

Fever weakens the activity of digestive enzymes, resulting in a decrease in the ability to digest food, which in turn may cause loss of appetite and poor appetite. At this time, the diet should be light and easy to digest, moderate and nutritious, you can eat cereals rich in carbohydrate spine compounds, some fresh vegetables and fruits, in order to maintain or improve the body's immunity and restore health.

Once the body temperature exceeds 37 degrees Celsius, it is considered a fever.

Medical research has confirmed that the combat ability of immune cells will increase with the increase of body temperature, and at the same time, high body temperature will also reduce the concentration of iron ions in the blood, resulting in insufficient supply of trace iron ions required for the growth of pathogens, and then inhibit the development of pathogens.

Therefore, if you take fever-reducing medicine at the beginning of the fever, it may worsen the condition. When your body temperature does not exceed 38 degrees Celsius, and your spirit and appetite are not affected, you can put ice cubes on your forehead to relieve discomfort, drink plenty of water, supplement vitamins and minerals in moderation, and eat some nutritious and light food.

For example, the temperature of the cavity is divided into fever according to the level of fever:

Low-grade fever: Moderate fever:

High fever: Ultra high fever: 41 or more.

The highest heat tolerance of the human body is 43 and rarely survives. A persistent increase in rectal temperature above 41 can cause permanent brain damage, and a high fever above 42 for 2 to 4 hours often leads to shock and serious complications.

If it exceeds the degree, it is a fever, and low-grade fever should not be treated with antipyretics. If it exceeds 38 degrees, it should be taken for more than 3 consecutive days.

Normal body temperature is 36-37 degrees. If it is exceeded, it is a fever. Among them is low-grade fever. Medium heat. for high fever. A temperature of over 40 degrees Celsius is considered to be ultra-high.

Excerpt from the Medical Certificate).

36 degrees Celsius is considered normal body temperature, and more than 36 degrees Celsius is considered fever.

A person's normal body temperature is generally below 37 degrees Celsius (Celsius), which is considered normal body temperature and is tested under the armpit. Tested from the oral cavity to degrees (Celsius) or less. Celsius) is low-grade fever. Excess is high fever.
