Although it may not in any way resemble your heart, kidneys, liver or lungs, your skin is your body’s largest organ. In fact, the average adult body plays host to a massive 21 square feet of skin, which weighs around nine pounds, contains an incredible 11 miles of blood vessels and 45 miles of nerves and is made up of some 300 million skin cells.
Far from being a permanent fixture, skin has the amazing ability to constantly regenerate itself, with around 50,000 skin cells being shed every minute, or 3 million very hour. These cells account for 1.5 pounds of skin lost in the course of a year, or 105 pounds during a lifespan of 70 years. Globally, it is estimated that skin accounts for around 1 billion tons of dust in the atmosphere and 70 percent of the dust in your home. If all that has been enough to make your skin crawl, then you might just want to think about getting the vacuum out!
