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
( from Milady’s Standard Textbook for Professional Estheticians by Joel Gerson)
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. Skin breathes through sweat, and oils.
When we have a cut, it is like a opening of a sealed package and infections can enter through it. When skin has rashes and other changes in its properties, it can be from something it came in to contact with or it can be showing us a condition of the internal workings of our body. People who smoke or drink alot will find they have dry skin as they have used substances that dry the internal organs.
Clean diets, exercise and movement, plenty of sleep, you know all that which we say is healthy works for skin. Fruits are especially nice for skin.
Take care of your skin. Have others check your back from time to time. Keeping your skin healthy and clean are good health practices.
