Heat exhaustion is not usually serious if you can cool down within 30 minutes. If it turns into a heatstroke, it needs to be treated as an emergency.
Check for signs of heat exhaustion
The signs of heat exhaustion include:
- a headache
- dizziness and confusion
- loss of appetite and feeling sick
- excessive sweating and pale, clammy skin
- cramps in the arms, legs and stomach
- fast breathing or pulse
- a high temperature of 38C or above
- being very thirsty
The symptoms are often the same in adults and children, although children may become floppy and sleepy.
If someone is showing signs of heat exhaustion, they need to be cooled down.
Things you can do to cool someone down
If someone has heat exhaustion, follow these 4 steps:
- Move them to a cool place.
- Get them to lie down and raise their feet slightly.
- Get them to drink plenty of water. Sports or rehydration drinks are OK.
- Cool their skin – spray or sponge them with cool water and fan them. Cold packs around the armpits or neck are good, too.
Stay with them until they're better.
They should start to cool down and feel better within 30 minutes.
