Climate change is expected to increase the frequency, intensity, and duration of heat waves. This may increase the risk of heat-related illnesses, especially for those at risk.
How To Prevent Heat Illnesses
Be aware and prepared to handle an extreme heat event. If you have any symptoms during extreme heat (for example, feeling dizzy, weak, or overheated), you should:
- immediately move to a cool place (that is, indoor environments <26°C)
- rest by sitting or lying down
- drink water
Remember to take it easy after feeling better from cooling off, as you may still be at risk afterwards.
Stay Cool
- Dress in light-coloured, loose-fitting clothing, wear a hat and apply sunscreen.
- If feasible, open your windows at night and create a cross-breeze. Close awnings, curtains, or blinds during the day to reduce heat indoors.
- If you have an air conditioner, set it to a comfortable temperature. For those at risk during extreme heat events, sustained exposure to indoor environments over 26°C can pose a risk to health.
- Reschedule activities as needed to avoid being out when it’s hottest.
- Avoid using the oven or other appliances that will add heat to your home.
- If you must do physical activity in the heat, take extra breaks, remove excess clothing, and keep hydrated.
