Residents should also know the signs of heat-related illnesses like heat exhaustion, cramps, or heat stroke.
Heat stroke is considered a medical emergency justifying a 911 call or hospital visit. Signs of heat stroke are a throbbing headache, confusion, nausea, dizziness, body temperature above 103 degrees, hot, red, dry or damp skin, rapid and strong pulse, fainting, loss of consciousness. A person experiencing heat stroke should be moved to a cooler space, given cool clothes or bath, and not be given fluids.
Heat exhaustion is possible with symptoms of heavy sweating, weakness or tiredness, cool, pale and clammy skin, fast and weak pulse, muscle cramps, dizziness, nausea or vomiting, headache or fainting. A person experiencing heat exhaustion should be moved to a cooler environment, have clothing loosened, given cool and wet cloths, sips of water or a cool bath. Medical attention may be needed if symptoms worsen or last longer than an hour or if vomiting occurs.
Heat cramps can be the first sign of heat illness and could lead to heat exhaustion or heat stroke. Symptoms include heavy sweating as well as painful muscle cramps and spasms, typically in the legs and abdomen. To help someone with heat cramps, apply firm pressure on cramping muscles or lightly massage. The person should be given sips of water unless they feel sick.
