(HealthDayNews) -- Here's one for all you couch potatoes.
Lying around can actually help improve the air quality in your house.
The National Research Council's Board on Environmental Studies and Toxicology in Washington, D.C., says that particles of dust and other stuff in the air are bad for your lungs. So when researchers studied the sources of indoor air particles in Boston, they came up with a list of activities that endangered air quality.
The main culprits of bad air in most homes are cooking, cleaning and people moving around. Baking, broiling and toasting were major sources of small particles, while vacuuming, dusting and people moving around filled the house with large particles. And frying produced particles of all sizes.
