In Norway, airing out homes during winter is crucial, even in freezing temperatures. Residents follow a simple rule of opening windows three times a day for ten minutes to refresh indoor air and reduce humidity. This practice helps prevent condensation, which is common in colder months due to temperature differences. Experts recommend creating a draft by opening multiple windows simultaneously to replace stale air without losing significant heat. Special attention should be given to areas like bedrooms and bathrooms where humidity is higher. Maintaining a relative humidity of 40-45% and a stable indoor temperature of around 20-21 degrees Celsius is essential for a healthy living environment. Regular airing can help prevent mold growth.
