The mercury will rise across the country this week. From now on, we no longer speak of a heat wave but of an early heat wave. The temperatures announced should be higher than the seasonal averages of around 5°C to 15°C, specifies La Chaîne Météo. They should be between “20°C at night and more than 35°C during the day”.

For the time being, 20 departments are placed on alert from Tuesday June 14 at 3 p.m. until Friday June 17 at 6 p.m.

To protect yourself from high heat, it is necessary to apply the right gestures. Here is the advice of Public Health France:

To follow this last advice, you must know when you should ventilate your house or not. Here’s what to do.

This is one of the big questions we ask ourselves when the hot weather returns: how to keep your home cool? To do this, simply keep your windows, shutters and curtains closed all day. Thus, the hot air from outside does not enter your home.

Also remember to close the doors of your house, especially those of the kitchen and the bathroom. This way, you will keep the fresh air in each of your rooms.

As soon as the outside temperature drops and the sun goes down, you can ventilate your house by opening your doors, windows, shutters and curtains again. In this way, you will enjoy a lighter atmosphere and the coolness of the night.

Attention ! Remember to close your entire house well early in the morning, before the temperatures rise.
