HOW HOT IS TOO HOT?

Your body's temperature is a balance between heat production and heat loss. This balance is controlled by the hypothalamus in your brain, which acts as your body's thermostat to maintain a set body temperature. Fever occurs when the body's thermostat is reset to a higher degree. A variety of conditions can cause a fever, such as infection (either viral or bacterial), serious injuries (referred to as trauma), certain cancers, some drugs, and a few other disorders (seizures, arthritis, etc.).

When is a temperature considered a fever? Since each individual is unique there is no one specific number for normal or abnormal. Generally speaking, however, 98.6?F, plus or minus one degree, is considered a normal body temperature with a value of 101?F or greater being a fever. To check your temperature you need a thermometer. There are many different kinds of thermometers with a wide range in price and convenience. Disposable strips, glass, digital, tympanic (ear), even pacifiers for infants, are all good choices depending on your needs. If you don't have a thermometer, a good indicator that your temperature may be on the way up is if you are experiencing chills (that is, others around you seem comfortable in t-shirts and you have three sweatshirts on!) That's because chills result from the need for muscle activity to raise heat production and increase body temperature.

What should you do if you have a fever? Fever itself is not harmful, but it can be uncomfortable--Tylenol or Ibuprofen - two tablets every four hours - can be taken. Dressing lightly (multiple layers of blankets and clothing can trap heat and keep your temperature up), and/or a tepid bath may also be helpful in lowering a fever. 

If you have a fever, when should you see your health care provider? Most fevers resolve within 48 hours. An elevated temperature for more than 4-5 days should be evaluated. Also, if you experience any of the following symptoms with a fever contact your health care provider: burning with urination, discharge from the vagina or penis, severe abdominal pain, severe headache, rash, sore throat or ear pain.
