heat exhaustion vs heat stroke vs stroke
the symptoms can be v similar, but the treatment is v different.
Heat exhaustion symptoms include heavy sweating, clammy pale skin, and muscle cramps. Typically the person is dizzy, incoherent, or faint. Get the person to shade/cool air, and help them drink water (only if fully alert). Use cold compresses, and only shower if the person is fully conscience, otherwise there is a risk of fainting/drowning.
Heat stroke is most easily noticed due to the lack of sweat combined with hot dry skin. for heat stroke, getting to a hospital for intravenous fluids is extremely important. DO NOT force liquids, as the patient can vomit or choke. get the person to shade/ac as fast as you can & use cool damp cloths to cool temp until help arrives. call 911 immediately once you notice the hot, dry skin (or whatever the emergency service number is where you live)
