Heat Exhaustion: When Cooling Down Cannot Wait
Too hot? Know when to act.
Dizziness, heavy sweating and nausea on a hot day deserve attention. Heat exhaustion can progress to heatstroke, a medical emergency.
Start cooling straight away
Move into shade or air conditioning, remove unnecessary clothing and cool the skin with water and a fan. Offer cool water if the person is fully alert and swallowing safely. Stay with them.
Know when it is an emergency
Get emergency help immediately for confusion, poor coordination, a seizure, unconsciousness or serious breathing difficulty. Do not wait 30 minutes when these signs appear. Also get emergency help if the person is still unwell after 30 minutes of cooling, rest and fluids. Keep cooling while help is coming.
Plan your next outdoor day
Take cooling breaks, wear loose clothing and avoid strenuous activity during the hottest hours.
