Why is it advisable to ventilate your house every day?
Opening your windows wide to ventilate your home is essential for the health of its occupants.
Why ?
We spend 85% of our day in closed places (transport, office, house), where the air quality is worse than outside.
Indoor air pollution is said to be 5 to 10 times higher than outdoor air (volatile organic compounds known as VOCs, paints, glues, furniture, allergens, dust mites, etc.)
Ventilating the rooms for indoor air circulation therefore makes it possible to evacuate pollutants from the house, to fight against humidity and thus to clean the air.
An essential gesture for children, pregnant women, the elderly, and people with respiratory problems that are significantly more sensitive to indoor pollution.
When to open the windows?
The ideal is to open the windows every day to renew the quality of indoor air and breathe healthier air.
Depending on the season, the ideal opening time may vary:
In summer, it is advisable to open your windows between 9 p.m. and 10 a.m.: the air is cooler and of better quality.
In winter, ventilate rather in the morning between 8 am and 11 am or in the evening after 10 pm.
How long should you ventilate your home?
Opening your windows for 5 to 10 minutes a day is enough to completely renew the air in your living rooms.
A duration that does not cool your walls and furniture, but significantly cleans the ambient air.
Ventilation makes it possible to evacuate stale air, bad smells, humidity, dust, carbon monoxide, etc.
If your home has windows on both sides, don't hesitate to open them at the same time to create effective air currents, which then make it possible to reduce the opening time.
To note
It is better to open a window wide for 10 minutes than to leave it ajar for an hour.
This could cool the wall around the window and create condensation.
Who says condensation, says humidity and potential development of mold.
How to ventilate your home in winter without losing heat?
The first instinct in winter would rather be to leave the windows closed, to avoid the loss of hot air outside, and then increase its energy consumption.
However, domestic pollution is very present, in winter as in summer and for your health, it is important to clean up the indoor air as much as possible.
Of course, it is possible to install, in addition to the ventilation grilles, controlled mechanical ventilation systems (single-flow VMC, double VMC, kitchen hood, air conditioning), an air purifier or to have plants depolluting in your home.
But ventilation is simpler and more effective.
In addition, contrary to popular belief, not ventilating the room precisely contributes to consuming more energy.
Why ?
In winter, the indoor humidity level tends to increase a lot (breathing, humidity in the bathroom, water vapor in the kitchen, etc.) and heating a humid interior requires more energy than a home with a dry air.
A ventilated environment therefore consumes less energy to heat.
To benefit from cold and fresh air without losing heat,
it is therefore necessary to open your windows wide 5 to 10 minutes a day.
It is recommended to turn off the heaters at this time.
Renewing the air in your home daily is good for our health and will allow you to save energy.
