In our world of anti-bacterial products, could we be overdoing it? Cleanliness is important and certainly has played its role in modern medicine, but is there any negative side effect from being TOO clean?

The answer is yes, according to a study led by Thom McDade, PhD, associate professor and director of the Laboratory for Human Biology Research at Northwestern University. Dr. McDade's team found that exposure to parasites, bacteria, and viruses early in life is precisely the type of stimulation that the young immune system needs so it can learn, adapt, and regulate itself. Without having this exposure, children face a greater chance of developing allergies, asthma, and other autoimmune diseases when they become adults.

In other words, too much cleanliness makes the system more vulnerable to serious conditions down the line. According to Martin Blaser, MD, professor of internal medicine at New York University, "Microbes perform important physiological functions but because of modern life they are changing and some are disappearing. Those disappearances have consequences -- some good, some bad."

In fact, Dr. McDade's team found, among other things, that children who had more exposure to animal feces and more incidence of diarrhea before age two had a reduced incidence of inflammation in the body as they grew into adulthood.

But why does exposure to germs early in life seem to have this protective effect? Experts attribute it to something they've given the colorful appellation, "the hygiene hypothesis." The hygiene hypothesis was first espoused more than 20 years ago by David P. Strachan, a professor of epidemiology at St George's Hospital Medical School in London. His colleague, Marc McMorris, M.D., a pediatric allergist at the University of Michigan Health System, explains, "We've developed a cleaner lifestyle, and our bodies no longer need to fight germs as much as they did in the past. As a result, the immune system has shifted away from fighting infection to developing more allergic tendencies."

Essentially, the hygiene hypothesis holds that our greater reliance on antibacterial products, the use of airtight windows and doors, the smaller size of the modern family, and the use of vaccines and Antibiotics have all reduced our bodies' exposure to germs and infectious diseases. This essentially has left the immune system unemployed, and to paraphrase an old maxim, "idle immune cells are the devil's tool." The immune system is also designed to recognize foreign substances as allergens, and without bacteria to combat, it goes to town "creating" allergic conditions and inflammatory responses to irritants -- just to keep busy.

Naturally, parents want to protect their kids from scary infectious diseases, but how can they on the one hand protect them from infection while at the same time allow them enough exposure so that the kids don't later develop allergic conditions and systemic swelling?

Perhaps the answer is to just let kids be kids. If your kid picks up a piece of food from your floor and sticks it in her mouth, don't freak out -- assuming you clean the floor occasionally. If she comes home muddy, don't whip out the antibacterial soap, which not only wipes out germs but also screws up the environment and puts the entire family's health at risk from chemical exposure. In short, cleanliness may indeed be next to godliness, but being overzealous may play the devil with your health.
