Fever is one of the most effective mechanisms that our body uses for fighting infections. The average body temperature is 98.6° Fahrenheit, but it may vary from person to person. During a fever, the body temperature rises to 100.4° Fahrenheit. Flu may be the most common cause of fever; however, there may be other causes, which include:
- Bacterial and viral infections
- Autoimmune diseases, such as rheumatoid arthritis
- Reactions to drug or vaccine
- Certain types of cancers
The best way to bring down a fever include:
- Get some extra fluids: Getting some extra fluids while having a fever helps the sick person a lot. Body fluids are lost through sweat during fever. It is essential to replenish these lost body fluids. Besides, fluids also help to cool the body temperature.
- Taking sufficient rest
- Removing extra clothing to allow heat loss through the skin
- Getting a sponge bath in lukewarm water (85° to 90° Fahrenheit)
- Eating bland and light foods that are easy to digest
