How to Air Your House in Winter For Good Health.

With the onset of winter's cold and the operation of heaters, airing out your home remains crucial, not only for a pleasant aroma but also for good health. While in summer, leaving windows open for hours is common, in winter, the approach changes.

The question arises: how many minutes are needed to properly ventilate an indoor space, and what other factors influence this?

According to experts at Linternaute, opening windows in winter allows fresh air to circulate, improving indoor air quality by eliminating pollutants, odors, and moisture. It's vital to open windows at regular intervals throughout the day for about 5 to 10 minutes.

5 to 10 minutes

Experts recommend that daily ventilation of 5 to 10 minutes can significantly improve air quality without causing substantial heat loss.

Various factors indicate if a space requires more minutes of ventilation. For instance, the size of the space and activities within it, like cooking or exercising, significantly increase the needed ventilation time.

Weather conditions also play a role. On milder winter days, it's easy to air out your home without significant heat loss. However, during bad weather conditions or very low temperatures, the duration should be reduced to minimize heat loss and prevent the house from cooling down.

In general, prefer to 'open' your house during the day when the outside temperature is not very low. It's not necessary to have windows wide open for effective space ventilation. Even slightly open windows allow air renewal in the room without causing a significant drop in indoor temperature
