Overview
A fever is classified as an increase in the body temperature that is above the normal body temperature. In most cases, a fever is caused by some sort of infection. Most people have a normal body temperature of 37’C. The normal temperature can fluctuate by a degree or two based on the individual, and changes throughout the day or night. Most people believe that the higher the fever the more dangerous their illness, but this is not the case. In fact, a mild fever, classified as up to 39’C can actually help the immune system to rid the body of an infection. For children, a fever can trigger convulsions, and a fever that is 42.4’C in anyone can cause permanent brain damage.

Treating Fever on your Own
If you develop a fever, there are treatments that you can do:
- Take over the counter fever reducers as stated on the bottle such as paracetamol or ibuprofen
- Drink lots of water
- Avoid anything that can cause dehydration like tea or coffee
