The dead skin cells reduce indoor air pollution

The skin cells that the body releases (an average of 500 million dead skin cells daily), but are a nuisance and a source of dirt indoors, they provide a benefit, suggests a study from Rutgers University, United States . According to research, the fats found in these cells helps reduce air pollution in these areas.

The study's authors explain that humans shed an entire layer of the outer layer of skin every two to four weeks. The resulting skin flakes of skin containing fats, including cholesterol and squalene.

Previous research had suggested that squalene from the skin of the passengers could reduce levels of ozone (a pollutant that irritates the eyes, nose and throat) in aircraft cabins.

In this study, scientists analyzed the effect of these fats from the skin in homes and nurseries. Thus, it was found, among other findings, squalene accumulated dead cells indoors contributes to a reduction in those of between two and 15% of the levels of ozone.
