How often do you dust your home? Chances are your doctor would like you to do it more.
Dust is made up of skin cells, your hair, pet hair and dander, bits of clothing and stuff you track in from outside. But it can also have small amounts of cleaning products and other chemicals you use around the house. If you have an old house, it could even contain lead paint.
Obviously, dust poses more danger for people with asthma or bad allergies. But experts say that even if you don't have those problems, you shouldn't risk inhaling possible toxins. Dust regularly, and consider wearing a mask while you do.
And if you dust the ceiling fan, make sure you're on a stable surface and don't fall. (USA Today)
