Heat exhaustion vs heat stroke – do you know the difference?
Heat exhaustion is the body’s response to an excessive loss of water and/or salt contained in sweat. It can be treated by cooling down the body’s temperature by resting in a cool place, taking a cool shower, or drinking water.
When left untreated, heat exhaustion can turn into heat stroke, which is a life-threatening emergency. If you notice yourself or someone displaying symptoms, call Triple Zero (000) immediately.
If you are experiencing heatstroke, here’s what to do while waiting for help to arrive.
If the person is unconscious:
• Lay them on their side in the recovery position and check they can breathe properly.
• Perform CPR if needed.
If the person is conscious:
• Do not give them aspirin or paracetamol.
• Move them to a cool area and keep them still.
• Give them small sips of fluid.
• Cool them down with cold water or cool packs.
