During winter, maintaining good indoor air quality is key to health and comfort. However, it is not recommended to ventilate between 8 and 10 in the morning during severe frosts. This ban is based on several factors related to outside temperature, air pollution and energy efficiency.
Between 8 and 10 in the morning, human activity peaks – people go to work, traffic is heavy and the use of public and individual transport increases. This morning peak causes a significant increase in emissions and pollutants, especially in urban areas. By opening the windows at this time, more polluted outdoor air enters the home, which worsens the indoor air quality.
Morning hours are often the coldest, especially during winter. Ventilating between 8 and 10 o’clock means letting in very cold air, which will quickly lower the internal temperature. This decrease forces the heating system to work more intensively to restore pleasant warmth, which leads to higher energy consumption and, consequently, higher heating costs. A stable temperature in the house is important for energy efficiency.
Ventilating during the coldest hours disrupts the thermal balance, so heating devices must compensate for heat loss. This increased load not only increases energy consumption, but can also shorten the life of heating systems that are exposed to more frequent and intensive work cycles.
To achieve a balance between fresh air and keeping warm, it is recommended to ventilate at a more favorable time of day. The ideal time is around noon, usually between 12 and 2 p.m., when outside temperatures are higher and human activity is lowerwhich also means a lower level of pollution. A short but effective ventilation lasting 5 to 10 minutes is sufficient to freshen the air without significant loss of heat.
- Open the windows fully for 5-10 minutes to create a draft that quickly changes the air without cooling the walls and furniture.
- Prioritize ventilation of rooms with higher humidity, such as the kitchen, bathroom and bedrooms, especially after night.
- If you have mechanical ventilation, check that it is working properly. A well-maintained system ensures continuous air exchange without the need to open windows.
- Adjust ventilation to outside conditions – in case of increased pollution or extreme weather, choose a time when the air is cleanest and temperatures are milder.
Ventilation during the winter is essential to maintain high-quality indoor air. With the right timing and appropriate habits, you can ensure a healthy environment in the home and at the same time save on energy.
