Heatwaves are periods of intense heat that affect an area for several days, during which temperature variations (between low and high temperatures) are very small.
Heatwaves are a danger to public health, especially for people at risk.
Follow the prevention tips and safety rules.
To reduce risks during a heatwave, avoid excess heat, which puts a strain on the body. Here are some recommendations:
- When you are outdoors, take shelter under a parasol or wear a wide-brimmed, well-ventilated hat;
- Apply sunscreen to limit your exposure to ultraviolet rays;
- Limit physical activity, especially in the middle of the day, when it is the hottest;
- Drink plenty of water;
- Close the curtains and blinds to keep your house cool;
- Open wide all windows in the evening, if it is cooler outside; and
- Use the air conditioning to more quickly lower the temperature in your home.
You can offer to help your neighbours, above all if they live alone.
Your pets can also suffer from the heat. Avoid leaving them in the sun and give them water to keep them hydrated.
