Heat-related illness range from dangerous (heat stroke) to common (sunburn). From the Centers for Disease Control and Prevention, here are how to recognize and treat them.
• High body temperature (103 degrees or higher)
• Hot, red, dry or damp skin
• Fast, strong pulse
• Losing consciousness (passing out)
What to do: Call 911 immediately. Once that's done, move the person to a cooler spot, if possible, and apply cool clothes or give them a cool bath. Do not give them anything to drink.
• Heavy sweating
• Cold, pale, and clammy skin
• Fast, weak pulse
• Nausea or vomiting
• Muscle cramps
• Tiredness or weakness
• Fainting (passing out)
What to do: Move to a cooler spot; loosen clothing; apply cool clothes or take a cool bath; sip water.
• Heavy sweating during intense exercise
• Muscle pain or spasms
What to do: Otherwise, stop all physical activity until cramps go away; move to a cooler spot; drink water or a sports drink. If the cramps last more than an hour, you're on a low-sodium diet or you have heart problems, seek medical attention.
• Painful, red, and warm skin
• Blisters on the skin
What to do: Get out of the sun until the burn heals; apply cool clothes or take a cool bath; use lotion on burned areas; don't break blisters.
• Red clusters of small blisters that look like pimples on the skin (usually on the neck, chest, groin, or in elbow creases)
What to do: Stay in a cool, dry place; keep the rash dry; use baby powder to soothe the rash.
