We wouldn’t be alive without electricity because body functions are controlled by electrical signals. If your body didn’t conduct electricity, touching a high-voltage fence or sticking a knife in an electric socket would have no effect on you. Your skin, and much of the rest of your body for that matter, conducts electricity. The term may sound a little geeky, but we think it’s pretty exciting, especially when we consider the amazing amount of information it can reveal about an individual. Yet another great thing about the skin is that it responds to changes, or stimuli, in a way that can be accurately measured via galvanic skin response. It acts as a barrier against environmental threats, contains nerve cells that detect changes such as temperature and pressure, can heal itself, and (ideally) keeps your body at a steady 98.6 degrees. It’s not only smooth and often nice to look at, but also helps to regulate many functions of the body. The skin is an amazing and versatile organ.
