Oh how we take our skin for granted, our envelope that protects us from the outside world. Our skin acts as the protective barrier between our internal body systems and the outside world. Its ability to perceive touch sensations gives our brains a wealth of information about the environment around us, such as hot, cold, pain, and pressure. Without our sense of touch, it would be almost impossible to exist in safety in the world! We wouldn’t feel our feet hitting the floor when we walked, we wouldn’t feel when something sharp cut us, and we couldn’t enjoy the feel of the warm sun on our skin. It is truly amazing how much information we receive about the world through our sense of touch, and although we still don’t know all the ins and outs of how the skin perceives touch, what we do know is interesting.
10 Did You Know facts about our skin…
1. Your skin drops up to 30,000 to 40,000 dead skin cells each minute of the daytime. That’s up to 4kg of skin for every year!
2. The thinnest skin is on our eyelids and is approximately 0.02mm thick.
3. “In the buff” became synonymous for “nude” in 17th-century England. The term derives from soldiers’ leather tunics, or “buffs,” whose light brown colour apparently resembled an Anglo-Saxon backside.
4. There are at least five types of receptors but there are millions and millions of them, in the skin that respond to pain, temperature, touch, pressure and movement.
5. Sweat is odourless; it’s bacteria that makes it smell
6. Each and every hair has its own personal muscle, the erector pili. This allows the hair react to temperature, to release or trap heat.
7. An average adult’s skin spans 21 square feet, weighs nine pounds, and contains more than 11 miles of blood vessels.
8. Your skin reflects your overall health so remember to eat a healthy diet and avoid junk food, do not smoke, exercise regularly, and drink plenty of water.
9. One theory for why our skin gets wrinkly in water is the result of osmosis. Water being pulled into dead skin cells (keratin) on our epidermis would cause them to swell. The swollen outer layer of skin, still tightly attached to the layers beneath, would then wrinkle due to the increased surface area.
10. White skin appeared just 20,000 to 50,000 years ago, as dark-skinned humans migrated to colder climates and lost much of their melanin pigment.
