First Aid - Key Points

If you think someone may be suffering from heatstroke, seek medical attention for them immediately; take them to a hospital or other medical facility.

First Aid - The 3 Most Important Points

  • Point1

    Move the person to a cool place

    First, move the person who appears to be suffering from heatstroke to an indoor area where the air conditioning is working.
    If you are outdoors and there is no indoor, air-conditioned space nearby, move the person to a shady area with good ventilation so they can rest.

  • Point2

    Loosen or remove the heatstroke sufferer's clothing and cool their body to bring their body temperature down

    Loosen the person's clothing to allow heat to escape from their body. Use ice to cool the person's neck, armpits, groin, etc. You can cool them down by splashing water on their skin, then fanning them with a paper fan or similar object. If you don't have a fan, create a breeze using a towel or a piece of cardboard, etc.

  • Point3

    Give them water and sodium

    If possible, give the person water and sodium together. Try giving them sports drink etc. to drink.
    If the person is vomiting or semi-conscious, there is a danger than the water may enter the respiratory tract, so don't force the person to drink.

While you are waiting for an ambulance, you can prevent the heatstroke victim's symptoms from worsening by performing first aid. Heatstroke is potentially fatal, and must be taken seriously.
