Increased bodily temperature
Increased bodily temperature or pyrexia can be described as having a body temperature which is above the normal baseline.  While there is no universally agreed upon value at which pyrexia occurs, its diagnoses ranges between 37.5 - 38.3°C (99.5 - 100.9°F).  For comparison, the average temperature of a healthy person is around 37°C (98.6°F). It is worth noting that a bodily temperature which exceeds 41.5°C (106.7°F) is an emergency which requires immediate medical attention and can potentially result in physical injury, long-term side effects, and death.  This effect is capable of manifesting itself in the two different forms which are described below:
- Fever is used to describe the body raising its core temperature due to illness. For example, a fever may be caused by a bacterial infection.
- Hyperthermia is classified as an uncontrollable increase in body temperature that typically originates from an external source. This most frequently involves heat strokes or the use of certain drugs.
