The human skin cell shedding rate (called the desquamation rate) depends on factors such as the location of the skin being considered, the total area being considered, and the person's age. Even keeping the skin location, skin area, and age constant will result in different rates for different individuals.
The basic data for making approximate calculations can be found at http://www.nature.com/jid/journal/v74/n1/abs/5616091a.html
and Table 2 in particular.
As an example, if we take the average rate of all subjects and all sample areas given in the Table 2 referenced above, we obtain an average rate of 945 cells per square centimeter per hour. Let's assume 945 cells per square centimeter per hour is close to the average desquamation rate for the entire body even though it depends on location and the table gives actual rates that vary from a low of 530 to a high of 1856. There are 10,000 square centimeters in a square meter. Average adult humans have a skin area of somewhere between 1.5 and 2.0 square meters. This means the average human has somewhere between 15,000 and 20,000 square centimeters of skin. Multiplying this area by the average of 945 cells per square centimeter per hour gives us
14,175,000 to 18,900,000 cells per hour or
236,250 to 315,000 cells per minute

What is the process of skin shedding called in humans?
Humans do shed skin. When skin cells die, it falls off your body it's called Desquamation. Every hour nearly 40,000 skin cells are shed, and it takes one skin cell about a month to complete the desquamation process. In fact, person from 2009 that says humans don't shed, the dust in your home is mostly dead skin cells. Your dead skin literally falls off your body.
How often do humans shed dead skin cells?
Every second.
Why do caterpillars need to shed their skin when they grow bigger but you humans do not?
Because animals such as caterpillars and snakes do not shed dead skin cells individually, an entire layer peals off at once instead. Whereas us humans shed millions of dead skin cells every day without us realizing it. :)
Is the outer layer of dead cells of the skin shed every seven to ten weeks?
False
Do people loose skin when they sleep?
Yes humans shed dead skin cells constantly and they can accumulate in our beds.
How many particles of skin does a human shed every hour?
one layer every hour
Why humanbeings donot shed their skin while they grow?
We do ! It's just that we shed our skin in bits and pieces (that's where most of the household dust comes from - dead skin cells !) Reptiles on the whole, shed their skin in one piece.
What is the average lifespan of colon cells?
The average lifespan of an intestinal cell is less then a week. The dead cells are shed and replaced by new cells. Illness and diet can affect the life span of these cells.
How are dead and worn cells in the body replaced?
It all depends on which cells. Some are not replaced. These are mostly nerve cells such as found in the brain. Other cells constantly die and are shed and replaced from tissues below them. An example of this are your skin cells.
Is the skin of your body dead?
your skin is technically and organ (called epidermis) and it is made of cells. sometimes the cells die, like and organ and shed then replace themselves. im sure about this, but i think your hair is the only dead part of your body.
How much does the dead skin shed daily weigh?
The weight of dead skin cells shed by each person daily is in the regions of 0.7 grams - so with 4 people in your home you will have 2.8 grams skin cells lying around as new dust each day. If you have pets, even more (referred to as pet 'dander').
How often should you wash your sheets?
As new skin is grown on your body, the old and dead cells are shed in small fragments (most of the dust in your house is actually dead skin cells). You fully shed your entire body over the course of around a month, so you should wash your sheets every week to prevent hygiene problems.
