Fever reduction generally refers to the lowering of body temperature. Hot hands and feet can be a sign of fever reduction, but they can also indicate a persistent high fever. Typically, they are not a sign of a continuing rise in body temperature.
Fever is relatively common and mainly divides into three stages: the temperature rising stage, the high fever stage, and the temperature falling stage. When the body's temperature is in the rising stage, the blood vessels and muscles may contract, reducing heat dissipation. The pores and blood vessels in the limbs also begin to contract, which can lead to symptoms such as cold hands and feet and white limbs. If it is a persistent high fever stage, the capillaries in the hands and feet are relatively rich, and fever may occur, which can help reduce the fever. During this time, hot hands and feet may be experienced.
In addition, during the temperature falling stage, the body needs to dissipate heat quickly. At this time, the pores are dilated, the blood vessels in the limbs gradually expand, and blood circulation accelerates. This can lead to symptoms such as hot hands and feet and excessive sweating. During fever, it is necessary to regularly monitor changes in body temperature. Warm water can be used to wipe the palms, feet, armpits, and other areas to achieve the effect of physical cooling.
If the underarm temperature exceeds 38.5°C, medication such as ibuprofen suspension, acetaminophen granules, and nimesulide granules can be used under the guidance of a doctor to achieve analgesic and antipyretic effects. If other discomforting symptoms appear, standardized treatment should be sought as soon as possible.
