O.4.4.1.2 Hyperthermia is caused by raised core body temperature due to failure of the body to keep its temperature within acceptable levels. It occurs when the body produces or absorbs more heat than it dissipates. When the body becomes overheated, several reactions are triggered. The body first tries to rid itself of the excess heat by increasing circulation in the blood vessels close to the surface of the skin, which is why the face and hands often turn red. Then, the body attempts to dissipate the excessive heat through cooling via the perspiration (sweat) it creates. Water, in this case sweat, transfers heat from the body 25 times faster than air. As the sweat evaporates, the skin is cooled and large amounts© IRATA International Annex O Page 28 of 45 2017-Aug-01
