The shortcut to reducing fever is not from drugs (antipyretics, antibiotics, etc.), but from increasing body fluid and appropriate physical cooling. Effective physical cooling in fever? Fever is not a disease per se, but a phenomenon that increases heat production and decreases heat dissipation in the body due to the stimulation of the thermoregulatory center by thermogenic sources in the body. Therefore, the starting point for reducing fever is to increase heat dissipation and reduce heat production. Antipyretic medicine is to change the condition of the thermoregulatory center and reduce heat production, which is only a prerequisite for reducing fever. The real effect of reducing fever needs to be achieved by physical cooling and increasing heat dissipation in the body. Effective physical cooling in fever? There are four ways to dissipate heat from the human body, that is, to reduce fever: 1, evaporation of water through the skin is the most important way to dissipate heat, accounting for more than 90%. So do not overdress your child when you have a fever, you should wear less cover. 2, heat dissipation by breathing. Breathing will increase and deepen when you have a fever. 3. Heat dissipation through the process of urination. Drink more water and urinate more often. 4. Through the process of defecation. So, when your child has a fever, you should help your child physically reduce the fever from these four aspects. How to do effective physical cooling when fever? First of all, ensure that the infant fluid intake as much as possible. The fever reduction process is mainly achieved by evaporation of water from the skin. If there is not enough water in the body, the effect of fever reduction is limited. In addition, in the premise of raising the room temperature, as far as possible to reduce the cover to facilitate skin heat dissipation. Also, a warm bath, warm towel wet compress is also a good physical cooling method. Ice bags or ice patches will also have a certain effect. There are two major forms of physical cooling: cold cooling and warm cooling. Through the ice patch or ice pack, resulting in local skin cooling for cold cooling, fever reduction effect is limited. Although the skin can feel cooler, the body temperature may not be reduced. The cooled skin vasoconstriction, but will prevent the body heat dissipation. Warm cooling is to raise the ambient temperature, use warm towels on the body, take a warm bath, etc. to cause skin vasodilation, which facilitates the dissipation of body heat. The correct view of physical cooling is that maintaining body temperature requires a balance between heat production and heat dissipation in the body. Fever is the result of increased heat production and/or decreased heat dissipation. To reduce fever, it is important to increase heat dissipation. Increased blood flow through the skin is the main route of heat dissipation. Under the premise of drinking more water, raising the room temperature and reducing the cover; warm baths are good methods; while ice packs and alcohol baths only take away local skin heat and have limited effect on reducing fever. The main reason for the poor effect of fever reduction is the lack of water in the body. Infants and young children do not like to drink water or milk when they are sick, parents must be patient to feed a small number of times to increase the body’s moisture, to help reduce fever, or take antipyretic drugs can not achieve the desired effect. In addition, the process of urination and stool can be conducive to cooling. In short, the shortcut to reduce fever is not from drugs (antipyretics, antibiotics, etc.), but to increase body moisture and appropriate physical cooling.
