What is the difference between heat exhaustion and heat stroke?
Heat stroke is a more severe condition and requires immediate medical attention, as it can be life-threatening. If you suspect someone is experiencing heat stroke, call emergency services and try to cool them down while waiting for help to arrive.
On the other hand, the Centers for Disease Control and Prevention says heat exhaustion can often be treated by moving to a cooler place, drinking water, and resting. However, if symptoms worsen or do not improve within an hour, seek medical help, as heat exhaustion can progress to heat stroke if not properly managed.

What to do
If you or someone you know is experiencing heat stroke, the CDC says you should call 911 immediately, move the person to a cooler place and use cool cloths or a cool bath to help lower their body temperature. However, the CDC says if someone is experiencing heat stroke, you should not give them anything to drink while they wait for medical help.
If you are experiencing heat exhaustion, the CDC says you should move to a cooler place loosen your clothes, put cool cloths on your body or take a cool bath, and sip on water. If you are throwing up, or if your symptoms get worse or last longer than an hour, the CDC says you should seek medical help.
