General Discussion

Hyperthermia occurs when a person's body temperature rises and remains above the normal; 98.6°F Most frequently, this occurs during the heat of summer and among the elderly. However, it may also be triggered by other medical conditions or certain medications.

Hyperthermia is sometimes induced as a palliative measure in the treatment of certain cancerous conditions.
