Heat stroke is a condition arising from extremely high body temperature, which leads to nervous system abnormalities (such as lethargy, weakness, collapse or coma). Abnormally high body temperature (also called hyperthermia) develops after increased muscular activity with impaired ability to give off heat due to high heat and humidity or respiratory obstruction. Heat-related illnesses, including heat stroke, heat exhaustion and heat cramps can occur after exposure to extremely high environmental temperatures. These illnesses occur in all mammals and can be prevented by taking proper precautions. |
