Chills with high fever must be covered with a quilt. Chills with high fever are the result of a weak body and chills, which require a quilt and sweating in order to evaporate heat and lower the body temperature. A high fever and chills are usually due to the release of endotoxins from endogenous pyrogens in the body, for example, the body is infected by bacteria, viruses, mycoplasma, fungi and other atypical microorganisms, so there is an inflammatory response, when the body releases endotoxins such as bradykinin, leukotrienes, tumor necrosis factor, interleukins and other substances, which will cause the central temperature regulating point to move up and fever will occur. If the infection is serious, there will be coldness around the body and chills, so it is necessary to cover the quilt, cover the sweat and drink a lot of warm water, but also through physical cooling methods to dissipate heat so that the body temperature drops.
