Indoor air is often three times more polluted than outdoor air. A major contributor to poor indoor air quality is the use of paints, stains, and finishes in homes. Oil-based paints are particularly dangerous, as they contain VOCs. Many VOCs have been shown to cause cancer, nervous system damage, and allergic reactions. While water-based paints are generally taken to be safer, they may also pose health risks, particularly to children. Many water-based paints contain propylene glycol and glycol ethers, which have been shown to increase asthma and other respiratory problems in children. To learn more, check out these articles on the health impacts of oil-based paints and water-based paints.

To reduce negative health effects, choose low-VOC paint and use caution while painting; ventilate by opening windows, use protective gear specified by the label, keep pregnant women and young children away from freshly painted rooms, close paint cans tightly when not in use, and eliminate all sources of flame when using solvent-based paints.
