True or false?
If you answered true to any of these, think again.
San Jacinto College’s Kristine Kern, emergency medical services program instructor, busts myths about preventing and responding to the top three heat-related illnesses.
Heat cramps are muscle pain/spasms with heavy sweating that follow intense activity. These can progress to heat exhaustion, when you still sweat but also experience headache, dizziness, nausea, vomiting, clammy skin, and more. With life-threatening heat stroke, your body can no longer sweat to cool off. Your temperature climbs to 103 degrees or higher, and you may pass out.
Do you know how to beat the heat?
Myth 1: I don’t have to worry until Texas heat reaches triple digits.
Kern: Anybody who has temperature regulation problems already, works outside and gets dehydrated, or works in a high-heat, high-humidity environment is at risk. It can happen when you’re dehydrated or don’t have the right balance of electrolytes. If you have diabetes and your sugar is too high, you’ll also get dehydrated.
If you fall and are lying on the asphalt, that can be 20-30 degrees hotter than the ambient air. The inside of parked cars is even warmer — about 40 degrees hotter than the outside temperature. Both of those scenarios can be dangerous when it’s 80 degrees outside.
But we should stay especially vigilant in Texas summers. In high heat and humidity, our bodies don’t manage temperature as well.
Myth 2: I won’t suffer heat exhaustion if I’m swimming.
Kern: We breathe water out of our body. When you’re thirsty, you’re probably dehydrated and already behind the ball.
From the beach to the pool, you should remain hydrated, stay covered, and don’t do things that cause sunburn.
Myth 3: I should pour cold water on someone who is experiencing heat exhaustion/stroke.
Kern: No, they will shiver to produce heat, and their body will get hotter. Remove them from the heat. Use tepid water on the groin, chest, nape of neck, and armpits to slowly bring their temperature down.
Have them sit down, drink cool water, and eat fruit like grapes and oranges for electrolytes. Don’t let them resume activities. Don’t give any drink to someone who is unconscious.
Call 911 if someone is suffering heat stroke, and call if you’re alone and already suffering heat exhaustion.
Myth 4: Heat stroke won’t happen to me.
Kern: It can happen to anyone. The key to heat-related is to be proactive:
Start every day ahead — drink water all the time in Texas. Don’t go over your limits and try to be Superman. It’s hot here. Get out of the heat when you need to, not when it’s too late.
