KEY Hyperthermia – Elevated body temperature. Conductive heat exchange – Physical contact with other objects resulting in heat loss or gain. Convective heat exchange – Heat lost or gained through a circulating medium, cool or hot air. Radiant heat exchange – Heat from sunshine increasing the body’s temperature, body sends blood to the surface of the skin to be cooled. Evaporative heat loss – Process by which sweat glands in the skin allow water to be transported to the surface, where it then evaporates, taking large quantities of heat with it. Wet Bulb Globe Temperature - WBGT Syncope – Heat collapse, fainting. Heat Rash – Prickly heat, red raised bumps accompanied by prickling and tingling during sweating. Heat Cramps – Extremely painful muscle spasms, commonly in the calf and abdomen.

KEY Heat Exhaustion – Inadequate fluid replacement of fluids lost through sweating. Profuse sweating, pale skin, temp. <102, dizziness, rapid pulse. Heat Stroke – Serious life-threatening emergency. Sudden collapse with loss of consciousness, flushed, hot skin, shallow breathing, temp. < 104. Chilblains – Prolonged constant exposure to cold. Skin redness, tingling, swelling, pain in toes and fingers. Superficial frostbite – Involves only the skin and subcutaneous layer. Skin is pale, cold, hard, and waxy. Deep frostbite – Serious injury in which tissues are frozen. Acclimatization – The process of becoming accustomed to a new environment. Acute Mountain Sickness – Going from low altitude to high altitude, ft. Headache, nausea, vomiting, sleep disturbance, dyspnea. Pulmonary Edema – Accumulation of fluid within the alveolar walls. Cough, headache, dyspnea. SPF – Sun Protection Factor. Circadian Dysrhythmia – Jet lag. De-synchronization of the athletes biological and biophysical time clock
