4 Dangerous Myths About Hand Washing

Posted: 05/16/11 07:00 AM ET

Did you know that antibacterial soaps are tied to a public health crisis? It's true. The fervent use of antibacterial soaps and other antimicrobial products may be contributing to a growing scourge: antibiotic-resistant bacteria.

Antibiotic-resistant infections now claim more lives each year than the "modern plague" of AIDS, and cost the American health care system some $20 billion a year.

What will it take before it's taken seriously?

Hand Washing -- Your First Line of Defense Against Infectious Disease

Washing your hands is your number one protection against the acquisition and spread of infectious disease, but you do not need to use antimicrobial soap to get the job done.

Numerous studies attest to this fact, such as this 2007 systematic review published in the journal Clinical Infectious Diseases, which confirmed that antibacterial soap containing triclosan did not provide any additional benefit compared with a non-antibacterial soap.

The authors concluded:

"The lack of an additional health benefit associated with the use of triclosan-containing consumer soaps over regular soap, coupled with laboratory data demonstrating a potential risk of selecting for drug resistance, warrants further evaluation by governmental regulators regarding antibacterial product claims and advertising."

Proper Hand Washing Technique

While you don't need antibacterial soap, it is important to use proper a hand washing technique. To make sure you're actually removing all germs when you wash your hands, follow these guidelines:

1. Use warm water
2. Use a mild soap
3. Work up a good lather, all the way up to your wrists, for at least 20 seconds
4. Make sure you cover all surfaces, including the backs of your hands, wrists, between your
fingers and around and below your fingernails
5. Rinse thoroughly under running water
6. Dry your hands with a clean towel or let them air dry
7. In public places, use a paper towel to open the door as a protection from germs that the
handles may harbor

Wash your hands when they look dirty, and prior to, or after, performing certain tasks that could spread infection, such as in these instances:

• Before and after preparing food, especially when handling raw meat and poultry
• Before eating
• Before and after treating wounds or taking/giving medicine
• Before touching a sick or injured person
• Before inserting contact lenses
• After using the toilet or changing a diaper
• After touching an animal, its toys, leashes or waste
• After blowing your nose or coughing/sneezing into your hands
• After handling garbage or potentially contaminated waste

Antibacterial Products Pose Several Health Risks

Once you understand that good-old-fashioned soap and water are just as effective as modern antibacterials, the second issue becomes that of side effects. In a 2010 press release, Dr. Sarah Janssen of the Natural Resources Defense Council is quoted as saying:

"It's about time FDA has finally stated its concerns about antibacterial chemicals like triclosan. The public deserves to know that these so-called antibacterial products are no more effective in preventing infections than regular soap and water and may, in fact, be dangerous to their health in the long run."

Yes, while paying more for antibacterial products you don't need, you're also putting your health at risk in a number of ways, including:

1. Early data shows that overuse may be contributing to the creation of hardier, more
resistant bacterial strains. Even the American Medical Association (AMA) does not
recommend href="http://articles.mercola.com/sites/articles/archive/2000/06/17/anti-bacterial-
soap.aspx" target="_hplink">antibacterial soaps
for this very reason.
2. Adding to your body's toxic burden.
3. Triclosan, the active ingredient in most antibacterial soap, not only kills bacteria, it also
has been shown to kill human cells, and has been shown to possibly act as an endocrine
disrupter.
4. These products kill both bad and good bacteria, which is another explanation for how
they contribute to the development of antibiotic-resistant bacteria and potentially also to
allergic diseases like asthma and hay fever.
5. A child raised in an environment devoid of dirt and germs, and who is given antibiotics
that kill off all of the good and bad bacteria in his gut, may not be able to build up natural
resistance to disease, and becomes vulnerable to illnesses later in life. This theory, known
as the hygiene hypothesis, could be one reason why many allergies and immune-system
diseases have doubled, tripled or even quadrupled in the last few decades.

Antibacterial Soap Mixed with Chlorinated Water is a Dangerous Mix

As if that weren't enough, when triclosan mixes with the chlorine in your tap water, chloroform is formed, which the Environmental Protection Agency (EPA) has classified as a probable human carcinogen. I warned about this compounding danger more than five years ago.

In tests that closely mirror typical dishwashing habits and conditions, researchers have found that triclosan reacts with free chlorine to generate more than 50 parts per billion (ppb) of chloroform in your dishwater. And, when combined with other disinfection byproducts (DBPs), the additional chloroform could easily drive the concentration of total trihalomethanes above the EPA's maximum allowable amount.

As I've discussed before, trihalomethanes are some of the most dangerous chemical byproducts there are. The maximum annual average of THMs in your local water supply cannot exceed 80 ppb (parts-per-billion), but there really is no "safe" level of these chemicals.

Why Use Something that has NO Clear Health Benefits and Plenty of Possible Health Hazards?

The research clearly shows that you do not need antimicrobial soap to effectively protect yourself from germs. All you need is plain soap and warm water. Ditto for your dishes and your laundry.

So please, avoid using antibacterial soaps and other products containing these hazardous ingredients. They're just harming you and the environment, and adding to a significant public health problem. They also cost more.

Instead, just use a gentle, chemical-free soap. Local health food stores typically carry a variety of natural soaps that will do the trick without harsh chemicals.

I stopped using antibacterial goop almost as fast as I started. Those things sting! They also dry out the skin, and just don't feel right. On some cruise ships they make a big show of asking passengers to use the antibacterial stuff before entering the dining room or buffet. I call it hygiene theater. They would get better results by having staff remind people "have you washed your hands?" but it wouldn't go over as well I suppose.

I've been saying this stuff is silly and bad for years. You build immunity by coming in contact with small amounts of bacteria and viruses. That's just common sense. Or maybe I take my education and upbringing for granted.

A good HAND SANITIZER will go a long way towards keeping you healthy, germ free, and safe from colds and flu. I use the germ-x which is mostly alcohol and filler.

When you return from a meeting, church, social gathering where you are in a room with lots of people it is a good idea to sanitize your hands and no just washing with soap and water does not do the job.

Returning from the grocery store where you may have touched packages or vegetables that others have fondled and caressed and sneezed on is a good time to sanitze.

Everytime you shake hands with someone you are at risk and might end up with their cold or their son's cold or their grand kids cold.

My aunt lived to be 90 years old and never got sick. She told me the secret was the hand sanitizer everytime you come home from going out anywhere.

In time humans will become immune (naturally) to dangerous drug resistant bacteria.

Indeed, natural anti-infectives such as tea tree oil have been shown superior to conventional sterilizers like chlorhexidine or silver sulfadiazine for MRSA http://www.greenmedinfo.com/article/tea-tree-topical-preparations-are-superior-standard-topical-regimen-clearance-mrsa-colonizat

I'm sorry: the scorge of MRSA is caused by nasal carriage. We don't treat people with MRSA infections without treating their colonization. From your reference tea tre oil could be used at the site of the wound, but to erradicate nasal colonization, mupirocin won by a landslide...(also the p values for tea tree oil barely make significance for this small study, not powered enough for real change in practice. Seems OK if you're a healthy adult for a lesion only, but for any high risk group, the standard is best. Also, if any further larger-powered study came up with similar conclusions in the past 7 years, we'd love to make it standard off care. As you know, mupirocin is generic...it's really not a "Big Pharma" thing.....maybe more of a "don't carry your MRSA around in your nose so you don't hurt someone more vulnerable than you." Sorry. I'd love natural remedies to work also. But this study is unconvincing.

Honestly, I don't know why you think MDs are against natural healing. If Tea Tree oil solved the crisis of MRSA, trust me, they'd use it.
