When the temperature rises, so does the risk of heat-related illnesses. Two of the most common - and potentially dangerous - are heat exhaustion and heat stroke. While they might sound similar, there are important differences between them. Knowing how to spot the signs and take action can make all the difference, especially during hot summer days.
IWe will break down the key differences between heat exhaustion and heat stroke, how to recognize each one, and what to do if it happens to you or someone nearby.
Heat exhaustion happens when your body gets too hot and starts to struggle to cool itself down. It’s usually caused by spending too much time in the heat - especially if you're being active or not drinking enough water.
While heat exhaustion isn’t immediately life-threatening, it can turn into heat stroke if it’s not treated quickly. So if you or someone else shows these signs, it’s important to act fast.
Heat stroke is much more serious - in fact, it’s a medical emergency. It happens when the body can no longer control its temperature, and it shoots up to 104°F (40°C) or higher. When this happens, the brain, heart, and other organs are at serious risk.
If you suspect someone has heat stroke, don’t wait - call emergency services right away.
| Heat Exhaustion | Heat Stroke | |
|---|---|---|
| Body Temperature | Below 104°F (40°C) | 104°F (40°C) or higher |
| Skin | Cool, pale, sweaty | Hot, red, and dry or damp |
| Mental State | Tired, dizzy, nauseous | Confused, unconscious, or seizures |
| Sweating | Yes - a lot | Often stops sweating |
| Treatment | Cool down and hydrate | Call emergency services immediately |
The best way to handle heat exhaustion or heat stroke? Avoid them altogether. Here are a few simple but powerful tips:
When it comes to heat exhaustion vs. heat stroke, the difference really matters. Heat exhaustion can usually be reversed if you catch it early. But heat stroke is a medical emergency that needs fast treatment.
By staying aware of the signs and taking a few simple precautions, you can enjoy the summer safely - without putting your health at risk.
Stay cool, stay safe.
