Fevers have a purpose
No one likes having a fever. Even thought your body has an elevated temperature, you will probably feel chilled, achy, and downright awful. However, the body is so smart that a fever is typically happening to help you overcome whatever it is that is trying to make you sick. The purpose of a fever is primarily related to its role in immune response and fighting off infections. Here are a few ways that fevers can be helpful:
1. Enhanced Immune Function: Fever is an essential part of the body's defense mechanism against infections. It triggers an increase in the production and activity of white blood cells, which are integral to the immune system's response to pathogens. This is known as leukocytosis.

2. Inhibition of Pathogen Growth: Fever elevates the body's temperature, making it less favorable for the growth and replication of many pathogens, including bacteria and viruses. This can limit the spread and severity of an infection.

3. Stimulation of Immune Responses: Elevated body temperature during a fever promotes the production of various immune chemicals and proteins, such as interferons, that help the immune system target and combat infectious agents.

4. Enhanced Healing: A fever can facilitate tissue repair and recovery by increasing the rate of metabolic and enzymatic processes. This is important for repairing damage caused by infections and injuries.
