Simple actions that can protect you and those around you during a heatwave.
⚠️ Heat can be deadly. During a heatwave, check on elderly neighbours, young children, and people living alone. A phone call can save a life.
Thirst is already a sign of mild dehydration. Drink small amounts regularly — at least 1.5 litres per day, more if you're active or outdoors.
Cucumber, watermelon, tomatoes, and citrus fruits help you stay hydrated. Avoid heavy meals and limit alcohol, which dehydrates.
Use SPF 30 or higher on all exposed skin. Reapply every 2 hours, especially after sweating. Don't forget ears, neck, and the tops of your feet.
Stay indoors or in the shade between 11am and 4pm when UV radiation is strongest. Plan outdoor activities for early morning or evening.
Wear light-coloured, loose-fitting clothing and a hat. Light colours reflect sunlight; tight clothes trap heat.
A parked car in the sun can reach 60°C in minutes. Never leave a child unattended in a vehicle, even briefly — children overheat far faster than adults.
People over 65 are at high risk. Visit or call them at least once a day. Make sure they have access to cool spaces and water.
Animals suffer from heat too. Always provide fresh water and shade. Never leave pets in cars or on hot balconies without shelter.
During heatwaves, many city halls open free air-conditioned rooms for the public. Check your local town hall website or call 3114 (France).
Public libraries, museums, and shopping centres are air-conditioned and free (or low cost). A great place to spend the hottest hours of the day.
