Paris, but also Lyon and Grenoble have experienced several pollution peaks in recent days. Some people tend to snuggle up at home in these cases, but is it a good idea?
Interiors more polluted than outside
The lack of rain and wind in recent weeks has made the air unbreathable in some cities. Faced with these pollution peaks, some of us have had the reflex to lock ourselves in our homes. An unfortunate reflex, according to a number of specialists. Because if your interior is not well ventilated, it will not be healthier than your car interior. It may even be 5 to 10 times more polluted than the pollution cloud that overhangs our cities.
” The indoor air is often too little renewed, CO2 and humidity accumulate there if we do not ventilate », Explains Pierre Guitton, founder of Teqoya, expert in air quality. ” It is therefore important to continue to ventilate, for example by opening the windows twice a day. ” To ventilate your home, however, it is recommended to avoid the most polluted hours. So open your windows early in the morning or early at night.
30% of outdoor pollution in our interiors
Mites multiply in confined and overheated interiors. Add to that the humidity and indoor pollution is at its worst. After the morning shower, it is therefore important to ventilate to avoid molds, which are known allergens.. ” The figures are clear: around 30% of outdoor pollution is found indoors », Adds Pierre Guitton.
If we add to this cocktail the chemical gas residues from furniture, paints and household products, the air in our interiors can become toxic, without even realizing it. ” Caulking at home is therefore not recommended, except for people with a particular pathological situation. », Complete pulmonologist Jean-Philippe Santoni, in the columns of Release. There is only one solution: ventilation!
