Why do I put my feet in the firebox by the fire, and sleep on the couch, and there are many covers?

Hello! There are many causes of fever:

Fever is due to the action of fever activators on the body, which in turn leads to the production of endogenous pyrogens (EP) and the action of the brain.

Schematic diagram of thermoregulatory feedback.

The thermoregulatory center, which in turn leads to the release of the mediator of the fever center, which in turn causes a change in the setting point, and finally causes fever. Common pyretic activators include exopyrogens from in vitro: bacteria, viruses, fungi, spirochetes, malaria parasites, etc.; From the body:

antigen-antibody complexes, steroids, etc. Endogenous pyrogens (EPs) come from EP-producing cells in the body, and their main types are: interleukin-1 (IL-1), tumor necrosis factor (TNF), interferon (IFN), interleukin-6 (IL-6), etc.

EP acts on the thermoregulatory center located at the POAH, resulting in the production of positive and negative regulatory mediators. The latter can cause changes in the setting point and eventually lead to the development of fever.

Fever is not a disease in itself, but a symptom. In fact, it is one of the mechanisms in the body to fight infection. Fever may even have its uses:

Shortens the duration of illness, enhances the effectiveness of antibiotics, and makes infections less contagious. These abilities should be able to counteract the discomfort experienced in the event of a fever.

The diagnosis of the etiology of fever of unknown origin (FUO) is a worldwide problem, and the cause of FUO is still unclear in nearly 10% of cases. Fever itself can be caused by a variety of diseases, such as infections, tumors, autoimmune diseases, and blood disorders, and cannot be clearly classified. In the past, such patients were usually seen by internal medicine physicians, but in most hospitals with more specialized specialties were mainly seen by respiratory physicians.

At present, many hospitals have opened infectious disease departments and classified FUO as infectious disease departments for diagnosis and treatment, which is a kind of progress and can improve the level of diagnosis and treatment. FUO has a precise definition and consists of 3 main points: the duration of the fever lasts for 3 weeks; body temperature many times"; The diagnosis is not confirmed after a 1-week complete history, physical examination, and routine laboratory tests.

It can be seen that although FUO itself is a symptom diagnosis, not a disease diagnosis, the diagnostic requirements are very strict.

Cold and fever? Sleeping on the sofa will not take off your clothes, and covering the quilt will not cause you to catch a cold and fever, but when you get up in the morning and take off the quilt, the surrounding body will suddenly cool down, so you are prone to cold and fever.

There are many kinds of colds, wind chill, wind heat, stomach, etc., and the one that sweats is good is wind chill, otherwise it is invalid.
