What is the cause of cold hands and feet and hot hair Mobile phone love asked

In general, fever and cold hands and feet may be caused by severe fever symptoms or endocrine and metabolic system diseases.

1. The symptoms of fever are more serious: fever is generally caused by the increase of heat production and the decrease of heat dissipation in the patient's body, if the fever symptoms are more serious, the patient's body temperature regulation center will adjust the peripheral circulation, resulting in the constriction of the blood vessels in the patient's hands and feet, thereby reducing blood circulation, resulting in the patient's fever and cold hands and feet.

2. Endocrine and metabolic system diseases: due to fever, the human body is in a state of high consumption, if you suffer from endocrine and metabolic system diseases, such as hyperthyroidism, etc., it will lead to the patient's peripheral circulatory insufficiency of the hands and feet, so that the patient will have fever and cold hands and feet. There are several reasons for cold hands and feet during fever:

1. There are common infectious factors, usually bacteria, viruses or pathogenic microorganisms, such as mycoplasma and chlamydia, invade the human body, and the body will produce an immune response, which will produce an immune complex of antigens and antibodies. The body will excrete the toxic substances that enter the body, which will shift the temperature setting point of the hypothalamic central nervous system upward, so it will cause fever, but at this time, the hands and feet will be cold due to the reaction of bacteria and viruses.

2. Common endocrine and metabolic system diseases will also have clinical symptoms of cold hands and feet, usually hyperthyroidism, when the body is in a state of high consumption, but the hands and feet will also be cold due to peripheral circulatory insufficiency.

3. During shock, there will also be a situation where the body is hot but the limbs are clammy and cold, such as septic shock and septic shock.

Because the temperature of the body is too high.

5. Generally, when the fever is severe, the hands and feet are cold, not necessarily wind chill or wind-heat cold, it may be a viral cold, or infectious diseases, various inflammations, etc., you should go to the hospital to do the corresponding examination to clarify, in order to treat the symptoms**.

61. We can't wrap our bodies with thick clothes, we must wear loose clothes, which is conducive to exuding excessive body temperature.

2. Drink more water, drinking water has the effect of regulating body temperature. Due to the high body temperature of the fever, the body should evaporate a lot of water, and drinking plenty of water can help reduce the fever.

3. At home, you can use 35-38 water to do a warm water scrub bath, which is conducive to reducing fever.

4. After diluting the alcohol with warm water, wipe the soles of the feet and palms of the children to dissipate heat volatile through alcohol.

5. If the fever is above, we should send it to the hospital in time**, and before or on the way to the hospital, we can also use physical cooling.

1. The body temperature of the human body is controlled by the body temperature center of the hypothalamus, and if there is inflammation in the body, the body temperature center will jump higher than the body temperature set point, with the purpose of improving immunity and inhibiting pathogenic bacteria. To achieve a higher body temperature, the body needs muscle tremors to generate heat, and at the same time constricts the blood vessels on the surface of the body to reduce heat loss, so when you have a fever, your hands and feet feel cold to the touch.

2. When there is a high fever, the blood vessels in the terminals of the body are constricted, and the blood circulation is relatively slow, so the hands and feet are cold; It is also possible that when there is a fever, the body's body temperature is damaged by the two-way feedback of the regulating center, which causes the body's blood to flow to the heart and brain, ensuring the blood supply to the heart and brain and other important organs.

3. Cold hands and feet during fever are more common in children, which is related to the fact that children's physical functions have not yet developed. Because the development of the pediatric nervous system is not yet perfect, the autonomic nerve, which is responsible for managing vasodilation and contraction, is prone to disorders.

4. In the case of fever, the peripheral blood circulation of the limbs is relatively not as good as before, and the blood supply to the limbs is also reduced, and if the temperature of the surrounding environment is low and the hands are exposed to the outside for a long time, the hands and feet will be cold.
