When Body Temperature Increases?

A fever is a temporary increase in your body temperature, and it's often caused by illness, according to the Mayo Clinic. A rectal, ear, or temporal artery (forehead) temperature of 100.4 degrees or higher generally indicates a fever.

What can cause your temperature to rise?

Fever or elevated body temperature might be caused by:
  • A virus.
  • A bacterial infection.
  • Heat exhaustion.
  • Certain inflammatory conditions such as rheumatoid arthritis — inflammation of the lining of your joints (synovium)
  • A malignant tumor.

What happens when body temperature rise up?

When temperatures rise, the body reacts by increasing blood flow to the skin's surface, taking the heat from within the body to the surface. This means sweat. As the sweat evaporates, the body cools down.
