What is the upper limit for increasing body temperature? Fever limit

Apparently, there is an upper limit of fever, above which the temperature of the “set point” cannot be shifted. Untreated fever is almost never higher than 42.2 ° C for rectal measurement and very rarely exceeds 41.1 ° C.

The fact that this is true even with severe bacterial infections is confirmed by materials collected even before antibiotics and other antibacterial drugs were used. It seems that there is some kind of protective mechanism that prevents the development of an excessively high temperature of the “core”. The existence of an upper limit confirms once again that fever is a controlled and regulated phenomenon.

When the temperature of the “set point” returns to the normal level, the body temperature begins to be perceived as excessive and the fever “retreats”. Muscle tone and heat production are reduced. The trembling disappears. Normalized skin blood flow and sweating. The skin temperature rises, the patient feels heat or heat, sweats profusely.

The picture of a decrease in body temperature is of the same type, regardless of whether the temperature of the “set point” is restored to the norm by the body itself or under the influence of antipyretic drugs.
