If you witness someone experiencing heatstroke, you can try the following means to cool them down immediately.
• Wet skin with a sponge while fanning air over the person.
• Apply ice packs to the person’s groin, neck, back and armpits.
• Give the person a cold shower or ice bath.
Stay Hydrated
Dehydration is one of the main risk factors for heatstroke. So nothing is more important than making sure that you drink plenty of fluids throughout the course of the day. Water replenishes the body and helps to cool the body’s core temperature. During summer heat waves, it’s even more important to make sure that you drink ample amounts of water throughout the day.
Drink water, vegetable and fruit juice. These are all good sources of essential vitamins and minerals that will keep your organs functioning at tip top shape, even in the hottest temperatures. Drink green coconut juice, coriander juice, boiled mango that’s been cooled and added to water, or juice from basil leaves. All of these are excellent at cooling the body and acclimating the body to the heat.
Drink a sports beverage to replenish salt levels in the body. Heatstroke often stems not only from dehydration, but also from salt depletion. Sports drinks that are high in electrolytes will keep your body’s salt levels at a premium level when you are outside.
