Detailed explanation-1: -Charles Weschler and colleagues explain that humans shed their entire outer layer of skin every 2-4 weeks at the rate of 0.001 – 0.003 ounces of skin flakes every hour.
Detailed explanation-2: -Humans shed about 600, 000 skin cells per day and up to 1.5 pounds of skin cells per year. Research from the Journal of Allergy and Clinical Immunology found that shedding skin contributes to 69 to 88 percent of dust in our homes–now, that’s gross.
Detailed explanation-3: -We shed about 600, 000 particles of skin every hour, which works out to be about 1.5 pounds of skin per year, or 105 pounds of skin by the time you reach age 70! In brief, our skin is actually food to various fungi, bacteria, parasites and worms.
Detailed explanation-4: -Soon, they’ll flake off. Though you can’t see it happening, every minute of the day we lose about 30, 000 to 40, 000 dead skin cells off the surface of our skin. So just in the time it took you to read this far, you’ve probably lost about 40, 000 cells. That’s almost 9 pounds (4 kilograms) of cells every year!
