Why do I feel cold when I have a fever, and do I feel hot or cold when I have a fever?

High fever is usually caused by an infectious disease. Before a high fever, you always feel cold first, which is due to the decrease in heat dissipation. Because the small blood vessels constrict, the blood flow decreases, there is no sweating, and the erector pili muscle contracts, so we feel chills.

Chills are accompanied by frequent shivering, which is mainly due to increased muscle activity to increase heat production. Heat production is more, less divergence, soon after, the body heat accumulation exceeds usual, the body temperature will rise, and wait until the heat production and heat dissipation are slowly balanced, the heat accumulated in the body through the expansion of blood vessels, the relaxation of the muscles of the whole body and a lot of sweating and fever, the heat will subside, so that the body temperature will return to normal.

Hypothalamic thermoregulatory center--- thermoreceptor - >

> cryoreceptors.

> thermoreceptors.

**Blood flow – > heat dissipation.

As well as some appearances, blood vessels, and erector pili muscles.

When it comes to glucagon and adrenaline, two hormones, both of which can make the body produce heat, not only shivering, shivering, etc., many are related to this, hehe.

Fever reduction is mainly divided into two major methods, one is the physical cooling we are talking about, using the principles of physics to reduce the body temperature to normal. We have also said before that the increase in body temperature is due to the imbalance between heat production and heat dissipation, and then it causes the setting point of the body temperature center to rise, and at this time, a body temperature increase, if we help the body to dissipate as soon as possible, more heat, so that his body temperature can return to normal.

The most common method is to drink plenty of plain water to help him sweat, and at this time the body temperature will be carried away from the sweat. Again, you can use some warm water, or warm water mixed with alcohol to try, rub **, especially this part of the large blood vessels, such as our neck, armpits, elbow fossa, groin, fossa and other positions, which can help the body better heat dissipation, and then make the heat dissipation more than heat production, so that you can achieve a, the effect of cooling...

Fever feels hot and burns until you are confused, have convulsions, and sometimes feel cold.

A person's normal body temperature is about 36 8, and a body temperature of more than 38 5 (adults) or 39 (children) is considered a high fever. The symptoms are: hot forehead, dizziness, and in severe cases, pain all over the body.

In fact, a high fever is not a disease in itself, but a symptom that alerts your body that there may be a disease. In fact, heat dissipation is good for the body, and this internal defense has the function of destroying foreign germs. If the temperature doesn't rise too high, let it dissipate heat naturally, which will help eliminate toxins.

Hello! Feel the cold. The body temperature rises when the body has a fever. The body surface emits a lot of heat, so the patient feels cold and even shivering. Shivering is the body's instinct when it feels cold, and muscle contractions can produce heat.

Cold and fever are divided into low-grade fever, dizziness, but not drowsiness, feeling sweaty on the body, but not serious, not so hot that it can't stand it, at most it is dizzy and uncomfortable, the head feels uncomfortable High fever, especially tired, throat fire, headache, fever, sweating, always want to sleep, dizziness is terrible, the whole body is like a stove, in the early stage of high fever, there will also be cold, especially cold, when you make yourself want to jump into the stove, you will suddenly have a fever, hot to death, I want to keep yourself in the refrigerator People have different physiques, The symptoms of cold and fever are also different, some people have a high cold, some people first cold and then hot, and a small number of people have a low fever.

I suddenly got cold this afternoon, it's summer, I know I'm having a fever, and now it's worse after work.

Normally, I have a fever and I feel cold. When I felt this way myself, I knew I might have a fever.

It's hot, it's hot, I'm now.

The body feels hot, but the feet are cold, cold.

It's cold under normal circumstances... So take some medicine as soon as possible and sweat. If it's not good, go get an injection during the day

It's mostly hot bars, especially the heads.

I think so.

It's going to be cold, drink some ginger syrup.

The forehead is hot, but the body is cold.

Of course it's cold!

I have experienced it firsthand.

I feel cold, and I have a fever right now

You eat more sugar and I was the same ten years ago.

Wind-heat cold is mainly used to dispel wind and cold, and the commonly used drugs are cold and heat clearing powder, wind and detoxification capsules, cold capsules, etc.; Wind-heat cold is mainly a medicine for spicy and cool detoxification, which can effectively reduce the degree of fever, and the commonly used drugs are Yinqiaosan, Qinghe Jiedu Oral Liquid, Shuanghuanglian Oral Liquid, etc.

Why does a fever get chills and a rough open pick? It's so uncomfortable.

Hello, when a person is sick, the body temperature will be much higher than the normal body temperature, which is a fever. If a person has an infectious disease, he will also have a high fever. The fever of infectious diseases is due to the release of toxins in the human body by microorganisms such as bacteria and viruses, which are the thermoregulatory centers of the brain.

Of course, there are many reasons for high fever due to abnormal changes in the regulation of the body temperature center.

The beginning of the change is a decrease in heat dissipation on the surface of the body and an increase in heat in the production field. People always feel chills all over their bodies before they have a high fever, which is the result of reduced heat dissipation. Due to the constriction of the medium and micro blood vessels, the blood flow is reduced, there is no sweating, and the temperature is reduced, so we feel cold.

I hope the above inner rock Changrong will be helpful to you!

Why does a fever feel cold.

Why does the body feel cold with a cold fever.

When a person is sick, the body temperature will be much higher than the normal body temperature, which is called fever. If a person has an infectious disease, he will also have a high fever. The fever of infectious diseases is due to the release of toxins in the human body by microorganisms such as bacteria and viruses, which are the thermoregulatory centers of the brain.

Of course, there are many reasons for high fever due to abnormal changes in the regulation of the body temperature center.

Question 1: Does the fever feel hot or cold? Cold and fever are divided into low-grade fever, dizziness, but do not sleep, feel sweaty, but not serious, not so hot that you can't stand it, at most it is dizzy and uncomfortable, the head feels uncomfortable High fever, especially tired, throat fire, headache, fever, sweating, always want to sleep, dizziness, like a stove, high fever in the early stage, there will also be cold, especially cold, when you make yourself want to jump into the stove, you will suddenly have a fever, hot to death, I want to keep yourself in the refrigerator People have different physiques, The symptoms of cold and fever are also different, some people have a high cold, some people first cold and then hot, and a small number of people have a low fever.

Question 2: Why do people feel cold when they have a fever There are two kinds of fever, one is the fever of chills, the other is the fever of heat intolerance, the fever of chills is generally epidermal capillary constriction, and the heat in the body cannot be dissipated, which is manifested as high fever and chills, **Pale and no sweating; Fever is epidermal telangiectasia, which causes a large amount of heat in the body to be dissipated to the body surface, which is manifested as heat and sweating, and flushing. Of course, most people with high fever have chills and fever in the early stage, but in the later stage, it can be transformed into a fever of heat intolerance.

The manifestation of fever due to chills is epidermal capillary constriction, similar to the epidermal capillary constriction phenomenon when normal people are cold (in order to reduce heat loss), this physiological change gives people the feeling of nerves** is to feel cold or even shivering, so people with high fever will also have this feeling. Of course, because the body temperature is higher than that of a normal person, the outside world will feel colder than a normal person. There are also certain factors, but they are not the main ones.

Otherwise, it is difficult to explain why everyone else is dying of heat on a hot day in the summer, and they will feel cold even if they have a high fever.

Question 3: Do you feel very hot or cold when you have a fever In the early stage of fever, that is, when the body temperature rises, you may have chills and even chills, but after the body temperature is stable, you can feel fever and headache. Suggestions:

During the period of body temperature drop, it may be accompanied by sweating, and fever should be checked in detail to be clear, active, such as the use of penicillin, erythromycin, etc.

Question 4: Cold and fever, the body is hot but still feels cold, clothes Fever is the body temperature is elevated, which is equal to the external temperature is low, people will feel very cold, fever will accelerate the reproduction of pathogenic bacteria, fever symptoms need to be used in time to reduce fever with antipyretics, in addition to antibacterial anti-inflammatory.

1. There are pathogenic bacteria in the nasal cavity and throat of people all the time, when the body is cold, the body can not resist the reproduction of these pathogenic bacteria in the body, and these pathogenic bacteria will quickly multiply to the onset of the disease, first of all, causing upper respiratory tract infection, that is, runny nose and cough and other symptoms, if the ** is not appropriate, it will be infected into tracheitis pneumonia, which is a cold that everyone is easy to get.

2. According to the above situation, the cold must be treated with effective antibacterial drugs roxithromycin, penicillin, cephalosporin, azithromycin, etc., and acetaminophen tablets "antipyretic tablets" are used when there is a fever and headache, so that the cold is the safest and most effective.
