Heat Exhaustion and Heat Stroke – The Big Two (And How to Stay Out of the ER)

Alright, friends. We’ve talked about the small stuff: wobbly standing, cranky muscles, puffy ankles, itchy rashes, and sunburns that make you look like a tomato. Now we need to talk about the two villains that actually deserve your fear. Not panic, fear is useful. Panic is not.

Heat exhaustion and heat stroke are the heavy hitters of the Dog Days. One is a serious warning. The other is a life-threatening emergency. Knowing the difference, and what to do about each, could save your life or your neighbor’s.

Heat Exhaustion (The Warning Shot)

Heat exhaustion is your body screaming, “I am NOT okay!” It’s the stage right before things get really bad. The symptoms are hard to ignore, but we’re stubborn creatures, aren’t we? We tell ourselves, “I just need to finish this one thing.” Don’t.

Signs of heat exhaustion:

• Heavy sweating (but the skin may feel cool and clammy)
• Weakness or fatigue that feels extreme
• Dizziness or feeling like you might faint
• Nausea or an upset stomach
• Headache that won’t quit
• Fast, weak pulse
• Muscle cramps (hello, old friend)
• Dark urine (you’re dehydrated)

What to do immediately (and I mean immediately):

1. Get out of the heat. Go inside. Find air conditioning. If you can’t get inside, find deep shade, under a tree or a covered porch.
2. Lie down and put your feet up slightly.
3. Drink cool water or a sports drink. Sip, don’t chug. Chugging can upset your stomach more.
4. Apply cool cloths to your neck, armpits, and groin. That’s where large blood vessels live, so cooling those spots cools your whole body faster.
5. Take off any extra clothing (do this in private or don’t, I’m not here to judge).

Here’s the crucial part: You should start feeling better within 30 minutes. If you don’t, or if you start vomiting, call your doctor or go to urgent care. Heat exhaustion that doesn’t resolve can slip into heat stroke, and that’s where we stop messing around.

Heat Stroke (The 911 Emergency)

Heat stroke is not a joke. It is not a “tough it out” situation. It is your body’s cooling system failing completely. You stop sweating. Your internal temperature climbs above 103°F or 104°F. And your brain starts to get cooked, literally.

Signs of heat stroke:

• Hot, dry, red skin (no sweating, even though you’re burning up)
• Confusion, slurred speech, or agitation (person seems drunk or not making sense)
• Throbbing headache that’s worse than any migraine
• Loss of consciousness (passing out and not waking up quickly)
• Rapid, strong pulse (feels like your heart is trying to escape)
• Seizures (this is very, very bad)

What to do if you suspect heat stroke (in yourself or someone else):

1. Call 911 immediately. Do not wait. Do not “see if it gets better.” Do not drive yourself to the hospital unless there is literally no other option. Call an ambulance.
2. Move the person to a cooler place while waiting.
3. Cool them by any means possible. Ice packs on the neck, armpits, and groin. Cool water sprayed on the skin with fans blowing. If they’re alert enough to drink, give cool water, but if they’re confused or unconscious, do NOT give anything by mouth, they could choke.
4. Do not give fever medication like Tylenol or ibuprofen. This isn’t a fever; it’s environmental overheating. Those pills won’t work and can hurt the kidneys.

The best news? Heat stroke is almost entirely preventable. And prevention looks exactly like everything we’ve talked about all week:

• Hydrate before, during, and after being outside.
• Take breaks in the shade or air conditioning every 20-30 minutes.
• Wear light-colored, loose clothing.
• Avoid the hottest part of the day (10 AM to 4 PM).
• Check on neighbors, especially if they live alone and don’t have good AC.
• Know your limits. The person you were at 40 is not the person you are at 75. That’s not a failure. That’s wisdom.

A final Dog Days blessing:

May your water glass always be full. May your air conditioner hum like a happy bee. May you remember to put your feet up, wear your silly wide-brimmed hat, and laugh at Sirius from the comfort of your shaded porch. The ancient Romans thought the dog star would drive them mad. You know better. You’ll drink your pickle juice, wiggle your toes, and come inside before the world starts spinning.

And if you forget? If you overdo it? Call for help. That’s not weakness. That’s surviving the Dog Days like the seasoned, clever, wonderfully weathered human you are.

Stay cool, friends. The dog star will move on. And so will you.
