Gross But True: Your Dead Skin Can Reduce Indoor Air Pollution
As noted by Michael Bernstein and Michael Woods (check out their article on the ACS website) we all shed about 500 million cells of skin cells every day – that’s each one of us – which comes out to about .003 ounces of skin flakes per person per hour. The collaborative study by scientists in the U.S., Denmark and Sweden looked at dust samples from hundreds of bedrooms and day care centers as part of a broader Danish research project relating to indoor air pollution and children’s health. Given the rate of human skin shedding, the researchers predicted that skin flakes would account for a significant proportion of the material in house dust.
