Extreme temperatures can cause serious, potentially fatal health problems
Early warning signs of heat exhaustion include decreased energy, slight loss of appetite, faintness, light–headedness and nausea. People with these symptoms should seek a cool place, drink fluids, remove excess clothing and rest. Signs that require immediate medical attention include unconsciousness, rapid heartbeat, throbbing headache, dry skin, chest pain, confusion, irritability, vomiting, diarrhea, cramps, staggering and difficulty breathing. Dial 911, move the person to a cool area, remove excess clothing, then spray the person with water and fan the person until help arrives.
