No Five-Second Rule? Why Kids Shouldn’t be TOO Clean

Ditch the Five Second Rule

This is a guest post from Jena Halman-Kincaid, RN, board member at CSU.

Kids love to get dirty, don’t they? At least it seems like my girls do. On any given day they can be found in our backyard digging with their small shovels and piling dirt on one another. It’s in their hair, in one’s diaper, and under their nails. They are yucky.

You know what they also love? Eating things off the ground. My girls were the worst as babies when it came it putting “floor treasures” in their mouths. From a few months to two years old there was not a day that went by when I didn’t find them munching on something from the floor whether it be a toy, or shoe, or pea that rolled under the cabinet from last night’s dinner.

The Always-Learning Immune System

I know most of us moms can relate; new crawlers and toddlers alike can be found putting anything and everything they find in their mouths. But do you think that stops around two? Nope, it’s just not as obvious. What about that school aged child that drops his cookie on the ground and his parents aren’t around. You think he’s going to throw it away?…I think not, we all know where that cookie is going, in his mouth. Full of germs and dirt and icky stuff.

But is this actually a bad thing? Or is it that our children and babies innately know what is best for them? Are their natural tendencies smarter than our learned fear of germs? Most definitely. Our children instinctually know that an immune system only matures by being exposed to the icky grime we fear as a culture. And sadly this fear for all things dirty and grimy is leading us into an emerging era of poor immunity and chronic illness.

The development of our children’s immune systems is weighed heavily on their exposure to microbes. The immune system, much like our brain, is something that needs to learn as it goes. Think of it much like a child learning a new math concept. At first the concept overwhelms them, just as getting sick does. However, the subsequent times the “problem” is presented the child knows how to handle it because it learned to do so. These concepts then build on one another throughout time and eventually the child knows calculus.

But, if the child was to never learn basic math, something like calculus or even algebra would be insurmountable. Which is exactly how an immune system reacts when it never learns the basics. It rolls over and gives up, leading to a defunct immunity that reacts in unpredictable ways.

How can we foster a robust immune system?

In short, let our kids get dirty and don’t fear germs. Of course there are other factors that go into this as well like eating a Real Food diet, taking/eating probiotics, avoiding antibiotics, and preventing leaky gut. However, an overwhelming amount of evidence also shows that by allowing our children to be exposed to germs and illness at a young age their immune systems are more developed to handle what comes their way later in life.

Let’s take a minute to see what current research really shows. This study (via PubMed, source below) supports that early life exposure to a wide variety of microbes leads to a sturdy balance within the inflammatory system. As well as a lack of exposure can lead to a deficiency in immune development.

A sturdy inflammatory system is not only important to fighting off illness but also allergies and other chronic childhood diseases. According to a study from the Institute of Environmental Medicine in Sweden, “Epidemiological, clinical and animal studies taken together suggest that broad exposure to a wealth of commensal, non-pathogenic microorganisms early in life are associated with protection, not only against IgE-mediated allergies, but also conceivably against type-1 diabetes and inflammatory bowel disease.” So by allowing our children to be dirty we are not only preventing allergic diseases like asthma and eczema, but also IBS and diabetes!

Amazing that such a small intervention can have such big consequences later in life.

Besides actually letting our kids play outside with animals, dirt, and grime, another very important intervention is ending the frequent washing and sanitizing, both in their environments and their hands. Studies show that high levels of washing and/or sanitizing hands in 15-month-olds are associated with increased eczema and wheezing, and that those with eczema had it more severely if their hands were washed at high levels.

Yet another very large study, of 25,000 people, supports this theory as well. The researchers found that the more frequently antimicrobial products (personal care and household) were used in a home, the rate of allergy symptoms in children also increased. And if you still need more convincing a leading British respiratory medicine journal, Thorax, published a study that again shows the more frequently the home uses chemical household cleaning products the more the children have ongoing wheezing (an allergy predictor). Even up to twice as more likely! Editor’s note: here at Kitchen Stewardship® we love to talk about and use green household cleaners!

This is not to say the only cause of allergic conditions is overly-hygienic environments. Keep in mind that in some very dirty environments asthma rates are just as high or higher than overly sanitized ones. This “exposure hypothesis” works on a sliding scale; you cannot go too far in either direction.

Let’s all learn to maintain a healthy balance of germs for our children’s sake. Throw out those gallon sized portions of hand sanitizer, baby bottle/binky sanitizers, and rules about not letting children play in the dirt. Let them self-guide their play and use their own intuition to lead the development of immunity.

Why Your Kids Need Dirt

Lastly, always remember that a strong immunity is not developed due to a single factor. Things like gut microbiome, toxin exposure, antibiotic use, and diet are major players. This confirms that while playing in the dirt and not over-washing are important, those practices must be in tangent with other lifestyle choices like probiotic rich foods, environmental toxin reduction, and real food.

Two additional ways we can support a healthy immune/inflammatory system is entering daycare at an early age and exposure to farm animals.Bottom line, dirt is good and being overly hygienic is bad. Don’t reach for the sanitizer each time you blink and don’t worry about that cracker your kid just ate off the ground. These are all things that test and DEVELOP the immune system so later in life it knows how to function. With lower rates of autoimmune disease, obesity, diabetes, allergies, asthma, and inflammation your children will thank you later that those fun times in the dirt were not just merely for entertainment. Germs are nothing to fear and with properly developed immune systems our children can lead life strong, powerful, and healthy…the way they should be.

Do you already allow your kids to get dirty, or do you lean more on the germaphobe side? Does this research change your mind any?

  1. Interesting article. Have got to tell you my experiment as a child — and it worked! My mother was somewhat of a germaphobe. I remember having to go wash my baby brother’s toys when he threw them out of the playpen. Later I realized he was deliberately doing it to make me run. She wanted those toys washed but other areas were not cleaned. Go figure.

    I was sick a lot in early grades. A lot. Home more than in school I think. She had a strict rule, that if someone wanted to share a cookie or apple with me, I had to refuse. I had learned about the immune system and how it works, that if you get a little of a germ and the body reacts to it, you can get immunity.

    By about third or fourth grade, I decided to experiment. I was tired of being sick all the time. So when someone offered to share a cookie or apple, I accepted, thinking that if I get a little bit of their saliva or other germs, I will get immunity from whatever they are immune to. IT WORKED! Right at that point I stopped getting sick. I am at a grandmother’s age and am very healthy. I may get the flu once in five years, that’s all. (I have never had and never will have a flu shot.) The turning point was dramatic for me, and it was not being afraid of germs! BTW, I never told my mother what I did, never, not even years later.

    Great article! I do think it’s important, though, to make a distinction between “dirt” in the sense of germs and soil microbes vs. “dirt” in the sense of pollutants. Some of the dirt in your photos appears to be potting soil with wood chips–that can have some weird stuff added that helps plants grow but is not necessarily good for kids. Similarly, the “dirt” that comes in my open windows in summer, on the side of the house that faces a major street with diesel buses and is 1/2 mile from an interstate highway, is mostly made up of tiny black particles that I assume are from car exhaust, and therefore I try to minimize the extent to which my kids and I eat or breathe them.

  3. Germs and dirt and kids oh my!

    10 second rule applies here except in certain areas and depending on the item dropped.

    The least amount of cleaning chemicals possible helps as well.

    We have avoided lots of stomach bugs, flu and illnesses. I think a small part of that is due to my own strong immune system before their birth. Also exposure to people and kids outside the home from an early age has helped them build stronger immunity as well. Allowing their bodies to fight the infections without being impeded by medications like fever reducers also likely helped.

    Removing stress seemed to improve their bodies ability to fight off possible infections also seems to contribute to less illness

  4. I always figured that a good blow of air takes care of most things adhering to what is on the ground, etc. My oldest is nearly fifty and is healthy. Must have worked at the time. Seems to be OK for my grandchildren too. They are all thriving.

  5. I think dirt is probably the reason I’m glad my third child wasn’t also a girl (first two are). I would feel terrible giving that child third time hand-me-down clothes after all the dirt and play that goes on with my first two. We embrace dirt in our family! Nice article.
