Heat emergencies or illnesses are caused by exposure to extreme heat and sun. Heat illnesses can be prevented by being careful in hot, humid weather.
The first step in preventing heat illnesses is thinking ahead.
- Find out what the temperature will be for the whole day when you will be outdoors.
- Think about how you have dealt with heat in the past.
- Make sure you will have plenty of fluids to drink.
- Find out if there is shade available where you are going.
- Learn the early signs of heat illness.
To help prevent heat illnesses:
- Wear loose-fitting, lightweight and light-coloured clothing in hot weather.
- Rest often and seek shade when possible.
- Avoid exercise or heavy physical activity outdoors during hot or humid weather.
- Drink plenty of fluids every day. Drink more fluids before, during, and after physical activity.
- Be very careful to avoid overheating if you are taking drugs that impair heat regulation, or if you are overweight or elderly.
- Be careful of hot cars in the summer. Allow the car to cool off before getting in.
- NEVER leave a child sitting in a car exposed to the hot sun, even after opening windows.
