What Do Extreme Heat Warnings Mean? The main difference between a heat advisory and an extreme heat warning is the severity of its possible impact on people. That impact is not just a function of the high temperature, but also relates to how long it continues. Heat stress can be cumulative. A Heat Warning is issued when the combination of hot temperatures and high humidity combine to create a dangerous situation in which heat illnesses are considered likely among those receiving prolonged exposure, even individuals who are otherwise in generally good health. Drink plenty of fluids... stay in an air-conditioned room and out of the sun as much as possible... and check up on relatives and neighbors. Take extra precautions if you must work or spend time outside. When possible, reschedule strenuous activities to early morning or evening. Wear light weight and loose fitting clothing when possible and drink plenty of water. To reduce risk during outdoor work... the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Young children and pets should never be left unattended in vehicles under any circumstances! This is especially true during warm or hot weather when car interiors can reach lethal temperatures in a matter of minutes. Know the signs and symptoms of heat exhaustion and heat stroke. Both can cause weakness, dizziness, nausea, and muscle cramps, but heat stroke is a serious medical emergency. How can you tell the difference? Heat exhaustion is characterized by extreme sweating, clammy skin, and weak pulse. It can be treated by moving the patient to a cool, shady area, rehydrating him or her, and observing until the victim has recovered. But any one or more of the following symptoms can mean heat exhaustion has progressed to heat stroke: sweating stops, throbbing headache, reddening of skin, fever, confusion, unconsciousness, and/or rapid pounding pulse. Immediate professional help is needed.
