Things That Make Your Skin Crawl

Playlist Description

They're creepy, crawly and probably somewhere on your skin right now. That's right: Mites, bacteria, bed bugs, tics, fleas and more like to make their homes in our hides. Oftentimes they make their presence known with the appearance of bumps, rashes, visible injury or just general itchiness—yet just as often these microscopic bugs get comfortable without as much notice. So just what are the odds that you have tiny flesh-eating friends hanging around your body? Well the bacteria (and bug) population on our bodies reaches about 150 times the human population—meaning approximately one trillion nearly invisible parasites across more than 500 species are on our hair, skin, scabs, ears and much more right now. However, some of these bugs actually do some good work. For example, thanks to these little mites some of our infections and inflammation clears up quicker and potentially harmful or dangerous parasites are fought off by our bodily defenders.

So what types of bugs can we expect to be able to see with the naked eye? Adult fleas and ticks are generally visible. When a tick attaches itself to a host, it buries its head and begins to siphon out blood, later replacing it with a concoction that could contain Lyme disease. If you're bitten by a tick, you'll usually see a "bullseye" area, where a pink or red dot is encircled by a lighter pink area. Fleas, when matured, can also be spotted by humans, although good luck catching those bouncy bugs. Watch this playlist to learn more about the creepy creatures we carry around—and exactly what their purpose is.

Watch more First Aid: When Nature Attacks videos: As carriers of Lyme disease, ticks can be dangerous. Here's how to make sure you stay protected. Step 1: Remove with tweezers If you find a tick, never attempt to remove it by hand--use a pair of tweezers. Step 2: Sterilize tweezers Sterilize the tweezers by swiping them with a cotton ball soaked in rubbing alcohol, or by thoroughly washing them in soap and warm water. Step 3: Grasp tick's head with tweezers Press the tweezers as close to your skin as possible and grasp the tick’s head where it enters your skin. Do so carefully, and avoid crushing the tick’s body, which can release bacteria. Step 4: Pull tick away from skin Pull the tick directly away from your skin--do not attempt to twist or pry it out. Don’t panic if the tick’s mouthparts are left behind. Once the body is removed, it can no longer transmit bacteria. Tip Contrary to popular belief, trying to burn out the tick with a matchstick or smother it with petroleum jelly doesn’t work--the trauma causes it to release infected fluids into your skin. Step 5: Place into container Place it into a small, lidded container, such as an empty pill or spice bottle, and push a tissue in after it. Add a splash of rubbing alcohol to kill any bacteria. Step 6: Seal container & throw away Seal the container and throw it in the trash. Never flush a tick down the toilet--it can easily survive in water. Tip If you don’t have a small, lidded container handy, seal the tick in a small plastic storage bag or wrap it up in tape and throw it in the trash. Step 7: Clean area Thoroughly clean the area on your skin with soap and warm water, or rubbing alcohol. Did You Know?
