Here’s some advice we’ve provided before: Crack open your windows when it’s cold outside! Even though we’ve offered this piece of advice in the past, it’s worth repeating considering that much colder days are ahead. At first glance, the tip may seem like a strange one. Isn’t the whole point of keeping the windows shut when it’s cold outside to prevent it from being cold inside the home? Yes, of course. But keeping the windows shut also prevents pollutants from escaping your living space.

Open windows allow pollutants to escape.

As Mike Holmes explains in a special to National Post, there are numerous toxins inside your home. They build up over time and require open windows in order to escape. He lists volatile organic compounds (VOCs), mould spores, dust, smoke, radon, viruses and bacteria as some of the most prevalent pollutants in the home.

“Breathing these in over an extended period of time isn’t good for your health,” asserts Holmes, “It can make you feel sick, tired and drowsy, it can cause headaches, dizziness and nausea, and can irritate your eyes, nose and throat. It can even lead to building-related illness, or BRI. Symptoms of BRI include fevers, coughing, muscle aches and tightness in your chest.”

You don’t need to keep the windows open all day.

Don’t assume that you need to freeze yourself in order to freshen up the air in your home. Naturally, you’ll be inclined to keep your home as warm as possible during the coldest days of the year. No one is recommending that you slide your windows open during a blizzard. However, it needs to be reiterated that keeping windows shut 24/7 isn’t a healthy practice.

“15 to 20 minutes is enough to make a difference,” informs Holmes, “It’s also a good solution for homes that don’t have forced air. Yes, you will be losing some energy, but the health benefits you get from bringing fresh air into your home can offset this energy loss.”

MindBodyGreen.com agrees that throwing open a window is the simplest way to better indoor air quality during the colder months of the year. “Even when it’s chilly outside, you should open a window for at least five minutes a day to significantly decrease the concentrations of indoor air pollutants in your home,” the site advises, “Most home heating and cooling systems, including forced air heating systems, do not mechanically bring fresh air into the house. Manual is the way to go.”

Closed windows cause condensation.

Holmes also points out that keeping windows shut causes condensation inside the house. Condensation occurs when warm air hits cool surfaces. The problem with condensation in the home is that it appears as small droplets of water and this moisture is known for causing mould development. Mould spores in the air create major irritants for our respiratory systems.
