What is Fever?

Fever is also known as hyperthermia is elevated or body temperature. Normal body temperature varies from person to person, but it is usually around 98.6 F. It is really dangerous if it goes beyond 105 degrees Fahrenheit. However, the fever will stop at around 103 degrees or rarely goes over 104 degrees. A fever is simply an immune system response to an infection or toxicity in the blood.

Fever is not hazardous because it is your body’s primary defence mechanism that fights the infection. It stimulates the immune system present in your body and escalates the heat to where the organisms cannot survive. Fever is actually a health and wellness sign that can benefit you in many ways, including:

  • Creating more antibodies
  • Produces more white blood cells which can invade microbes
  • Produces interferon which prevents the spreading of viruses to healthy cells
