What to do when suspecting heat exhaustion?
If achievable, move the person out of the sun and into an air-conditioned space. Otherwise, try to provide them with as much shade as possible.
Lay the person down and slightly raise legs.
If you can, remove the person's clothing or loosen.
If possible, carefully cool the person's body by spraying or sponging him or her with cool water.
Give the person cool water or juice.
Fan air onto the person.
Monitor the person carefully because heat exhaustion can easily become heatstroke.
