"Why should one track their body temperature?"


Is it a good idea to track your body temperature? I've read somewhere online that keeping a close eye on your body temperature is actually a pretty good way to watch your general health and watch for problems, but I don't understand how or why that would be true.


The body is very capable of maintaining its temperature within a narrow range that is most compatible with health. One exception to this is fever, which is a raising of the body temperature in response to an infection. The fever rises in this setting because many of the bacteria and viruses that cause infections to not tolerate the increased temperature well, meaning that fever is an important part of the body's defense mechanisms.

In other words, temperature can be monitored when you feel that you are ill, because it can be one sign among others that your body is fighting off an infection. However, this is little utility to monitoring your temperature when you are feeling well. As always the diagnosis and the management of any particular condition will require a physical examination by your personal physician. Any time that you are concerned that you are ill, the best idea is to schedule a visit with your primary care doctor.
