Hypothermia and Hyperthermia
There are only a few signs of hypothermia; shivering violently, disoriented, and unstable on his or her feet. To treat, immediately make shelter and place the victim inside. Strip off the victim’s cold wet clothing and place him or her in their sleeping bag, bedroll or any other form of insulation to assist with warming the victim. It is often necessary for another person to also remove their clothes and get into the victims bedroll too, the body contact will raise the victim’s core temperature. If the victim’s body is still cold to the touch and they stop shivering take emergency action immediately, they are on the verge of death.
The signs of hyperthermia, also known as heat stroke, are shallow breathing, nausea or vomiting, dilated pupils, and dizziness. Also the victim’s face may become pale and they may break into a cold sweat. To treat heatstroke you need to loosen the victim’s clothing, begin fanning them, and place them in a shady area. They also need to begin drinking sips of water to rehydrate. In serious cases you can poor cool water over the victim or place ice packs in the arm pits, the groin and on the sides of the neck. Placing ice packs on primary arteries will speed up the cooling process.
