The heat wave can put your health at risk

As every year from the first days of the heat wave, the Directorate of Health Action sets up a system of information and prevention of risks associated with hot weather.

Exposure to high temperatures is not good for the body. The most serious complications are the risk of dehydration and heat stroke.

1. What are the risks associated with extreme heat?

High heat can affect your health.


Depending on age, the body reacts differently to high temperatures.

When one is old, the body sweats little, and therefore, has difficulty. As a result, the body temperature can then increase: there is a risk of heat stroke (hyperthermia – temperature above 40 ° with impaired consciousness).

As for the child and the adult, the body sweats a lot to stay at the right temperature. But as a result, we lose water, and we risk dehydration.

Also, during pregnancy, several diseases and the use of certain medications can, with high heat, lead to harmful consequences on your health. These problems should be discussed with your doctor and pharmacist.

Simple actions help prevent accidents. It is necessary to prepare oneself before the first signs of corporal suffering, even if these signs appear insignificant.

2. What to do in case of hot weather?

– Avoid outdoor activities that require excessive energy (gardening, DIY …) as well as physical efforts

– Wear a hat, light clothing (cotton), loose and light in colour

– Keep your accommodation cool (close the windows and shutters/blinds during the day, open them at night and in the evening if it is cooler)

– Hang a damp cloth in front of an open window

– If the temperature inside exceeds 32°C, the fan does not act against the oppressive heat because it brews the air without cooling it and accelerates the dehydration

– Water, if possible, in the evening after sunset, your terrace, balcony, especially those facing west
