Heat & Cold
Exposure to excessive heat can cause heat stress, heat exhaustion, and heat stroke. Painful muscle spasms, usually in the legs and abdomen, are the first signs of heat stress.
Heat exhaustion symptoms include skin that is pale, cool, moist, or flushed, as well as headaches, nausea, dizziness, weakness, or exhaustion. Heat stroke is an emergency condition characterized by hot, dry, red skin; unconsciousness; rapid weak pulse; and shallow breathing.
For all types of heat stress, get the victim to a cool location and give them small amounts of water or sport drink. DO NOT give salt tablets or salt water. Loosen tight clothing and apply cool wet cloths to the skin. Get emergency medical care as soon as possible if the victim refuses water, vomits, or loses consciousness.
Hypothermia is a dangerous drop in body temperature. Shivering, numbness, and unconsciousness are all symptoms. Getting the victim to a warm place and out of wet clothes as soon as possible is critical. Contact emergency services immediately.
