If you want to avoid getting sick, there are a couple things you can do. The best thing of course is to wash your hands. However a lot of people are not washing their hands correctly. It may seem like a simple thing, since most of us have been washing our hands since we were children, however, many of us were taught incorrectly, and many more of us have forgotten how to sanitize our hand to remove as many germs and microbes as possible.
You may be tempted to buy antibacterial soaps, and hand washes, however these antibacterial soaps are horrible for our environment. Every time we kill off the microbes and viruses on our hands, a couple of them survive. Sometimes they are so weakened that they will soon die, but other times, they are almost unaffected by the antibacterial soap. These diseases that survive antibacterial soaps can grow and multiply spreading the antibacterial resistant genes on to a next generation. This will lead to antibacterial technology becoming useless.
The same thing holds true with anti bacterial alcohol based hand scrubs. These scrubs also do not remove other contaminates such as chemicals, they merely put more on. You can end up poisoning yourself if you touch a chemical such as antifreeze and use an alcohol based hand scrub to clean your hands before eating. This can even leave you hospitalized. Also some chemicals can be irritating to your skin, which can cause burning over a long period of time.
The first thing you want to do when properly washing your hands is to turn on the faucet, and wet your hands. Wetting your hands will help the soap get into the tiny cracks and crevices and cleanse them. Now use the soap dispenser or a bar of soap to lather your hands. If you are using a bar wet the bar and gently rub it onto your skin until your hands are coated in it, you might see bubbles depending on what brand of soap you buy. Once you have your hand lathered rinse them under the faucet for twenty seconds, and allow for all the soap to wash away. Now you do not turn off your faucet Just yet. Take a paper towel and dry your hands. Once your hands are completely dry grab another paper towel, and turn off the faucet. You need a dry paper towel to keep stop the germs from penetrating the towel and going back onto your hands. Now use that paper towel to open the door and throw the towel away as soon as possible. This will leave your hands completely sanitized, and ready for you to get them dirty once again.
