‘Tis the season for germs

Like many things, the fantastical claims of antibacterial hand sanitizer gels seem too good to be true: namely, killing 99.9% of harmful germs and bacteria without water, anytime, anywhere. Especially for squirmy children who hate to lather up, hand sanitizers seem like a skincare dream. Available in fun scents and colors, these quick-acting alternatives to soap and water are readily available. Yet, are they as fantastic as they seem? A debate has been growing over the past few years, and it turns out that consumers may not be getting all the information when it comes to antibacterial products.

Soap smarts
On the most basic level, overuse of hand sanitizers is dangerous for the simple reason that many people are using these products to replace regular hand washing, however; it’s uncertain whether merely using a hand sanitizing gel is enough. Studies have shown that the only truly effective method of sanitizing hands is to wash for ten seconds using soap and warm water. Those who consistently replace hand washing with sanitizers actually may end up with hands, which are still unclean, spreading germs to others. For this reason, the FDA recommends that people use hand sanitizers only when soap and water is not available, and not as a replacement for hand-washing. For a refreshing, orange-scented hand-washing treat, keep Molton Brown Naran Ji Fine Liquid Hand Soap by the sink. And for the shower, Bliss Big Blue Bar will lather up for a super squeaky clean.

Hand sanitizers in action
What exactly happens when you use a hand sanitizer? Simply put, the products strips away the superficial layer of oil on the skin’s surface, taking bacteria along for the ride, and slowing down re-growth of new bacteria, as well. And even though most bacteria are killed, complete sterilization of all bacteria is not an ideal way to target germs. The body plays hosts to numerous forms of bacteria, both good and bad. And this bacterium is responsible for a host of important functions, such as metabolizing food and maintaining the pH of the mouth. Good bacteria are also found in nature, where they help to break down solid waste and trash, as well as enrich and fertilize the soil. Studies from the Immune Tolerance Network also reveal that in order to build a healthy immune system, kids must be exposed to all forms of bacteria in their early years. Kids who live in overly sterile environments are more likely to end up with allergies and other immune system complications.

Triclosan: A harmful ingredient?
Unfortunately, avoiding anti-bacs is not as easy as it may seem. Antibacterial products are not limited to hand sanitizers and these powerful substances are popping up all over: cutting boards, children’s toys, sandals, toothbrushes, makeup, and computer accessories are all increasingly featuring antibacterial agents. Many liquid soaps, as well as many other products, contain a chemical called triclosan, an antibacterial agent. One of the biggest problems with this type of ingredient? It kills all bacteria, both good and bad.

In an article on Grinning Planet, The American Medical Association states, “It may be prudent to avoid the use of antimicrobial agents in consumer products.” Not only is triclosan ineffective at preventing the common cold or flu in a healthy household (those are caused by viruses, not bacteria), but this chemical may also be dangerous. Beyond Pesticides finds that triclosan has been linked to dioxins, which are carcinogenic and could potentially be harmful to humans, causing birth defects and other dangerous consequences. The Environmental Protection Agency actually considers triclosan to be a pesticide because of its negative effects on the environment.

Super-bacteria?
The most serious concern about over-using antibacterial products is that germs are smart, and over time, will build up a resistance to these substances, resulting in “super-bacteria”. Because triclosan kills bacteria in a way similar to antibiotics, researchers worry that bacteria will also become resistant to bactericides, leading to even further health problems down the road. At present the debate rages on, and the issue is still being debated by scientists and researchers alike, with no definitive answers.

Concerned about triclosan and antibacterial products? It may be in your best interests to wash your hands the old-fashioned way. Turns out that plain old soap and water will effectively clean and sanitize the hands, with no safety concerns.
