Heat Exhaustion: Symptoms, Signs, Treatment, and Recovery

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.

What Is Heat Exhaustion?

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.

Signs of Heat Exhaustion:

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.

What to Do:

What Is Heat Stroke?

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.

Warning Signs of Heat Stroke:

If you suspect someone has heat stroke, don’t wait - call emergency services right away.
