Heatstroke and Heat Exhaustion 26 Jun, 2018

Heat Exhaustion

Heat exhaustion is caused by the body’s core temperature rising above 37oC. In an attempt to cool down, excessing sweating occurs. Fluids and vita salts are lost during this process. This condition can be caused through excessive exercise such as extended play, running around or prolonged exposure to hot conditions. Children under the age of two years are particularly at risk.

Heatstroke is a medical emergency.  The hypothalamus (the body’s thermostat) ceases working and the body cannot cool down through normal actions such as sweating.

The core temperature rises to dangerous levels (above 40oC).  Heatstroke is caused by prolonged exposure to hot conditions or as a result of an underlying physical condition such as fever or illness.
