How come when we have a fever, we feel cold? That's like a paradox.??
Answers: A body temperature above the normal range is produced by chemicals called pyrogens. One of their effects is to alter the body's normal temperature set point , around which body temperature fluctuates over the course of the day. This action occurs in part of the brain called the hypothalamus, which is responsible for maintaining many of the normal conditions of the body. Since the temperature set point in the hypothalamus has been altered substantially upward with the onset of fever, even a body temperature above the normal range will cause you to feel cold, even shake with chills, as long as the temperature is still below the altered set point . If your temperature continues to rise to approach the altered set point , you will gradually feel warmer, even hot.
If the cause of the production of pyrogens is eliminated, as in the process of recovery from an infection such as influenza, the hypothalamus will return the body's temperature set point to what is was originally. When this happens you may feel very hot and even sweat profusely as your body attempts to brint its temperature back to within the normal range. This is what's meant by breaking a fever. All of this represents a normal response of the body to changing conditions. The problem, of course, is that a fever makes us feel lousy, on top of whatever symptoms we may have, so most of us will use an antipy-
retic medication such as aspirin or acetominophen to bring our temperatures down while we endure the rest of our illness. As parents we give these medications to our children, too, because we want them to feel better. Note that the Food and Drug Administration recommends that aspirin should not be given to children or teenagers with symptoms of chickenpox or influenza because of a likely increase in risk of a rare but serious condition called Reye Syndrome. Tylenol is therefore usually the drug of choice for children with a fever due to a cold or the flu, unless your doctor specifically recommends aspirin. (American children are now protected against chickenpox by a vaccine). Also note that in most cases a fever will break and the body's temperature will return to normal without any help during recovery from typical infectious diseases. Most of us probably choose not to tough it out, however.
because your white blood cells are working on the part of you body that has the infection so theyre arent as many going through your body at the same time to keep you warm
