One square inch of your skin has:
- 65 hairs
- 9,500,000 cells
- 95 to 100 sebaceous (oil) glands
- 19 yards (17 meters) of blood vessels
- 650 sweat glands
- 78 yards (70 meters) of nerves
- 78 sensory apparatuses for heat
- 19,500 sensory cells at the end of nerve fibers
- 1,300 nerve endings to record pain
- 160 to 165 pressure apparatuses for the perception of tactile stimuli
- 13 sensory apparatuses for cold

This is why we are sensitive. Our ability to know when something touches us even when we are not looking.
Our skin is our largest excretory organ, that’s right it is a complete organ, with a total area of about 20 square feet. The skin protects us from microbes and the elements.
Take care of your skin. Have others check your back from time to time. Keeping your skin healthy and clean are good health practices.
