Fact: According to the US Environmental Protection Agency, indoor air quality is one of the top five environmental health concerns. Given that people spend about 90 percent of their time indoors, it's important to do what you can to reduce indoor air pollution.
Action: One of the simplest things you can do is open a window. Even if it's chilly outside (we should be so lucky!), you should open a window for just five minutes a day to significantly decrease the concentrations of indoor air pollutants in your home. Most home heating and cooling systems, including forced air heating systems, do not mechanically bring fresh air into the house. Open a window and start breathing cleaner air.
And play outside more!
