How Many Skin Cells Are Lost Each Day?

So just in the time it took you to read this far, you've probably lost about 40000 cells.

Every minute we lose 30,000-40,000 skin cells. That means in one hour we would lose 1,800,000-2,400,000. So in a 24 hour period we would lose around 43,200,000-57,600,000 skin cells. The human skin is a complex organ. It consists of several layers, which are involved in a range of functions, from defence against external pathogens to temperature regulation. The skin is the largest organ of the human body and renews itself every 28 - 30 days.

They actually do end up on our floors and furniture and everywhere. They are contained in the dust around our homes. They are small particles - not like when you receive a sunburn and peel in sheets. And being a natural substance they do break down so we don't see them in piles (well depending on how you live :)
