What Can I Learn by Testing My Home Biome?

What Can I Learn by Testing My Home Biome? | Blog

In the past several decades, modern life has revolved around a shared understanding of our homes. We see our homes as safe sanctuaries for living, relaxing, and raising our families. And as such, we’ve developed codes of conduct around keeping our homes clean, tidy, and void of anything unsafe or unsanitary. But have you thought, “What can I learn by testing my home biome”?

However, in recent years we’ve seen a rise in new health issues, which has sparked questions around the safety and health of our homes. We realize that our closed-in living spaces no longer include a relationship with our outdoor environment.

More importantly, researchers and experts are beginning to see that the lack of biodiversity inside our homes is problematic.

This has prompted some crucial discussions and research about what’s living and not living in our homes. Indeed, this may be the start of a new era of modern life where we change our ideas about what safe and healthy actually means for our home environments.

What Is A Home Biome, And Why Does It Matter?

The home biome refers to everything that lives in our homes. It may be surprising to hear that humans are the minority inside our own homes. In the book “Never Home Alone,” author and biologist Rob Dunn recounts the myriad of life that resides in our living spaces 1.

Not only do we live with other creatures like spiders and crickets, but we also share a home with thousands of tiny microbes, most of which are beneficial to us. The home biome matters as much to our health and well being as does a healthy diet or whether we get enough sleep each night 1.

Most of us have heard about the importance of a balanced gut biome. Yet, few understand that a balanced home biome is also essential. And that balance includes having many diverse microbes living in harmony with us 1,2.

In his book, Dunn refers to several studies looking at the differences between the home biome of modern people versus those who live surrounded by more biodiversity. For example, one study compared the microbes in modern homes with those of homes that were more open and connected with nature.

It turns out that the children raised in homes that contained more biodiverse soil-based microbes did not suffer from allergies, asthma, or other inflammatory conditions 1,3.

Dunn also discusses other expert findings that reveal a relationship between our modern lives and inflammatory disease. It turns out that when the biodiversity around us decreases, human inflammation increases 1,3,4,5.

The presence of microbes in our home biome are required for our immune system to develop appropriately. A balanced home biome makes for a balanced immune system that neither under- or over-reacts. The exact evolutionary reason for this health benefit isn’t completely understood yet. However, we do know that a closer connection to outdoor biodiversity is what brings balance to the home biome 1,3,4,5.

In short, our physical and environmental health depends on living with diverse microbes. And these microbes must include those found in the soil and natural environment.

We also know that a balanced home biome is a strong defense against the few harmful pathogens that can live with us. It’s interesting to note that out of thousands of microbes, only a few are actually harmful to us 1. Microbes such as mold, salmonella, and e.coli are the main ones that we try to avoid in our homes.

We now understand that a balanced home biome that includes soil-based microbes is what keeps these harmful pathogens from becoming a problem. We just need to figure out how to nurture a healthy home biome in this modern age.

 

What Can I Learn by Testing My Home Biome?What Is Home Biome Testing?

The first step in fostering a healthy home biome is to know what’s growing within its borders in the first place.

We know a musty smell points to mold growth. Or if we prepare food and someone gets sick, this may point to salmonella growing on our cutting boards or countertops. Our first reaction is to get rid of harmful microbes, but we rarely think about how to bring in good microbes that may be of help to us.

But really, if we don’t know what’s growing in our homes, then we can’t do anything about it. So testing our home biome gives us an incredible tool for understanding the health of our home.

Many of us have used the ERMI test, which covers about 36 species of mold, while the HERTSMI test includes about 5 species. In this way, we no longer have to guess what’s happening with our home biome. Instead, we can understand the health of our home by identifying any potential dysbiosis.

Over-Cleaning Causes Increased Fungal Growth in Urban HomesWhat Is Environmental Dysbiosis?

Again, we are beginning to understand what happens to us when our gut biome is out of balance. By now, many people have heard of dysbiosis in our gut and the accompanying health issues. Now, we need to look at dysbiosis in our home environments.

Dysbiosis refers to a biome that is out of balance. This means that certain harmful microbes are growing unchecked, while other good microbes are not growing enough 7.

The reasons why we have dysbiosis in our gut are actually similar to why we might have it in our homes. In essence, we kill off too many good microbes, which allow the bad ones to grow. In the case of our homes, this often happens by over-cleaning with harsh antimicrobial solutions 8,9,10.

Research shows that mold can indeed be much more common in household areas that are “too clean”. And in the regions that are less cleaned, there is a higher diversity of microbes and less mold 8,10.

What Can I Learn From The Results of My Home Biome Test?

By testing the home biome, not only can we learn which harmful microbes may be growing in our homes, but we can actively do something about it. Also, we can understand more about the levels of beneficial microbes as well.

Through a home biome test, we can see if we have a mold problem or not. Mold growth says a lot about the dysbiosis of our homes because we know that rampant mold growth means a lack of diverse microbes 8,9,10.

Through a home biome test, we’ll know the exact species growing in our homes, which means we can take the necessary steps to improve balance. Some of these steps include bringing in more soil-based microbes while easing up on our cleaning practices.

Where we were once obsessed with getting rid of dirt, perhaps now we need to relax more. Because having a bit of outside dirt in our homes, is quite frankly, exactly what we need.

While it may sound like a radical idea to bring in more dirt and clean less, the research is clearly showing that this is necessary for reducing environmental dysbiosis 1,7,8. In turn, this improves our own health too 1,4,5,7.

As our modern homes are less connected to the natural environment, this means soil-based microbes are no longer living with us the way they once did. And as mentioned above, without this balance, we’re seeing a rise in inflammatory disease.

Conclusion

Indeed, new developments in home biome research are making us pay attention to what’s living or not living in our homes. An increase in mold likely means we don’t have enough beneficial microbes. And this means that our homes may be in a state of dysbiosis.

By testing our home biome, we can arm ourselves with the knowledge we need to prevent or fix dysbiosis. And since we now understand the connection between home dysbiosis and the rise of inflammatory conditions, we must take steps to prevent this.

As our modern dwellings continue to change and evolve, we’ll need to figure out how we can maintain healthy homes that somehow include a relationship with our natural environments. As creative and intelligent beings, there’s much we can do to restore balance. And testing our home biome is an excellent step towards creating that balance.

Gut Biome & Home Biome: How Are They Related?

Gut Biome & Home Biome: How Are They Related? | Female holding her stomach

In the past decade, the importance of a healthy gut biome has been discussed between scientists, medical professionals, and health consumers. By now, most people know that bacteria reside in our guts and that they’re essential to our health. These bacteria are, together, what create the biome. However, many people still don’t understand why having diverse bacteria is important. More importantly, most people don’t understand the similarities and relationship between our home biome and the gut biome. We need the biome in our guts and our homes to be healthy and diverse at the same time.

Why Does Biome Balance Matter?

As living organisms, we’re connected to our living environments, so if one biome is unbalanced, chances are the other is too. Also, by understanding the similarities between the gut and home biome, we can make better decisions for how to improve and maintain them. However, many of us may not understand that the home biome is similar to the one in our gut. Therefore, people may not realize how to create balance in our home biome.

First let’s define both the gut and home biomes and look at their similarities. Then we can discuss the importance of both biomes for the health of our bodies and living environments.

What is The Gut Biome?

The evidence is clear that having healthy and diverse microbes in the gut is essential for the development, functioning, and maintenance of our overall physical health. Gut microbes impact the digestive system, our immune system, our neurochemicals, and many other systems in our body 1,2,3.

For example, gut microbes are needed to help digest and absorb nutrients from the food we eat. This helps sustain the immune system, which is also connected to the nerves, brain, blood vessels, and other vital organs 1,2,3,4. Research shows that a gut biome that lacks diverse and healthy bacteria may be a root cause of health problems like diabetes, obesity, cancer, inflammatory bowel disease, and autoimmune issues 3,4,5,6.

We’re all born with a sterile gut that becomes populated by essential microbes in infancy. The particular distribution of microbes is unique to each individual even though we share many microbial species between humans 1-6. Many issues can cause us to lose the diversity of our gut microbes. Things like illness, antibiotics, chemicals, food additives, and stress can all cause a shift in the balance of bacteria in our guts. This imbalance is called dysbiosis 5,6. Dysbiosis refers to both the loss of our gut microbes as well as an overgrowth of harmful microbes.

Why Are Healthy Gut Microbes Important?

A gut without enough microbes means that we may not have the ability to digest enough nutrients. Also, if one microbe is allowed to grow too much, this can lead to other health issues as well. An example of an overgrowth of harmful microbes is in a common condition known as candidiasis. This is an overgrowth of Candida yeast in the gut known to cause bloating, headaches, brain fog, and other health problems. Yet another example is a bacteria known as c. difficile, which is known to cause severe diarrhea 3-6.

In recent years, many health professionals are advocating for the use of pre and probiotics to help control dysbiosis. There’s also been much discussion of the overuse of antibiotics as they are known to kill healthy gut microbes. Lastly, we know that things like maintaining a healthy diet or decreasing stress can also help retain the microbe balance in our guts 1-6.

The goal is to create an environment in our guts where diverse microbes can grow in healthy amounts. This healthy diversity not only contributes to the proper functioning of our bodies, but it prevents unhealthy microbes from growing in large numbers.

When it comes to the health of our guts, we need lots of healthy and diverse microbes that live well together and in balance.

What is The Home Biome?

Now that we understand the gut biome, let’s look at the home biome. Our homes also have a biome that is unique and essential in maintaining the health of our living environment. Just like our guts, our homes get colonized with a variety of diverse microbes, some of which are required to maintain balance and health. If our home biome is lacking in microbes, such as often happens when we overclean and create a sterile environment, then problems can arise 7,8.

Also, if we clear out a few key species of microbes that help maintain balance, we may see an overgrowth of other more harmful species. For example, microbes like mold, yeast, and salmonella can grow unchecked in a home environment that lacks sufficient diverse, healthy microbes 7,8.

So, we also need to consider ways to enhance the growth of healthy bacteria, the same as we would do for our guts. Just as we take probiotics for our gut health, we can also use probiotics for our home. Products like Homebiotic Probiotic Spray contain healthy soil-based microbes that help maintain the home biome. Also, just as we work to prevent a sterile gut, we want to avoid a sterile home environment. This means we don’t over-clean our homes with harsh chemical cleaners too frequently 7,8.

Just as we take probiotics for our gut health, we can also use probiotics for our home. Products like Homebiotic contain healthy soil-based microbes that help maintain the home biome. Share on X

How Are The Gut & Home Biome Related?

Since we are biodiverse beings that are dependent on our environments, it makes sense that our gut and home biome co-exist. Of course, the microbial population in our guts and our homes will be somewhat different. But, studies show that homes are colonized by bacteria found in humans and pets that live in the house 8.

Interestingly, some microbes that are unique to the home and the immediate outdoor environment also live in our bodies. We know that this relationship creates a diverse biome, and this diversity is fundamental to our well-being as a whole. So obviously, if there is dysbiosis in the home, then there may be dysbiosis in the human biome as well 7,8,9,10.

Indeed, in recent years, research shows how the use of chemicals to clean our bodies and living environments can also affect the human biome 7. Also, we know that homes surrounded by diverse soil-based microbes such as farms or homes with a lot of green space are known to create healthier immune systems in children. This suggests that a direct connection to our environment is what actually creates robust body systems 9,10,11,12.

Lastly, a home that is lacking in diverse microbes is likely to have an overgrowth of harmful microbes like mold. In recent decades, mold illness in the form of allergies, asthma, and other related health issues are on the rise. So we know that our home biome has an effect on our health and well-being 11,12.

Why is This Important To Know?

The more we understand the connection between our gut and home biome, the more we know how to maintain health in both areas. As living beings, we are symbiotically connected to our environments. People are becoming more educated about the importance of healthy and diverse gut microbes. Still, they have yet to see the connection between their gut and their home biome.

The more we understand the importance of having diverse microbes in our guts and in our homes, the more we will take care not to create a dysbiosis in either. As we try to enhance our physical health to ensure the diversity of microbes in our gut, we can also do the same thing for our homes. It just makes sense to look after both so we can improve our overall health.

How Mold Impacts the Environment

How Mold Impacts the Environment | Hands holding a bonsai tree

You may be familiar already with some of the health effects associated with mold exposure, but have you considered how mold impacts the environment? The environmental impacts can go much further than the initial mold issue. Specifically, the impacts of traditional mold killing remedies can have far-reaching environmental effects.

Many people tend to reach for a bottle of bleach (or other bleach-based products) when tackling household mold issues, but as we’ve discussed before, bleach is not a good choice for dealing with mold. Beyond the health impacts of exposure to bleach, its use can lead to significant environmental impacts within your home and the areas around your home.

Negative Impact: Air Quality

According to the EPA, Americans spend roughly 90% of the time inside,1 where the concentrations of some pollutants are 2 to 5 times higher than concentrations typically found outdoors2. This situation is made worse when we consider that the people who are most vulnerable to poor air quality (eg. infants and children, the elderly, and anyone suffering from respiratory or cardiovascular disease) tend to spend more time indoors than others3.

In recent decades, as buildings have become more and more airtight for energy efficiency (itself not a bad thing, of course), indoor pollution levels have risen sharply. This is primarily due to a lack of sufficient mechanical ventilation in sealed buildings to allow adequate air exchange, as well as the rise in popularity of industrial-strength cleaning products now marketed for home use4.

Usually, because these products tend to be extremely irritating to your eyes and mucous membranes (nose, throat, lungs), it’s suggested that they are only used in a “well-ventilated” area3. While this certainly can remove the pollutants from the immediate vicinity of the person using them, it does still result in noxious fumes being released to the outside air. In past decades, the phrase “Dilution is the solution to pollution!” was often repeated, but despite the catchy rhyme, it’s definitely not a solution. It’s also not just for air. This applies to what goes down your drain as well.

Negative Impact: Water Quality

If you live in a rural area or are on a septic system, you’ll no doubt already be aware that flushing bleach down your drain is a big no-no. But did you know that it’s also bad even if you are on a city sewer system? Nearly every wastewater treatment system uses bacteria to break down sewage, and exposure to antiseptic products within the wastewater can disrupt the beneficial bacteria. This can result in a reduced or incomplete breakdown of the biological material. In addition, many wastewater treatment systems are not designed to break down chemicals and so often they pass right through the system and are discharged into a lake, river, or other nearby body of water – sometimes the same body of water where drinking water is sourced from!

It gets worse.

Common household bleach, also known as sodium hypochlorite, contains a reactive chlorine atom which readily reacts with both organic and inorganic material in water to form a group of substances called trihalomethanes. The 4 trihalomethanes are chloroform, bromodichloromethane, dibromochloromethane, and bromoform5. These are all byproducts of the reaction of disinfection products with non-purified water, such as is found in household wastewater. Each of these is a Cancer Group B carcinogen (substances shown to cause cancer in laboratory animals). 

Trichloromethane (chloroform) is by far the most common in most water systems. Dibromochloromethane is the most serious cancer risk, (0.6 ug/l to cause a 10-6 cancer risk increase) followed in order by Bromoform (4 ug/l), and Chloroform (6 ug/l). EPA regulations strictly limit these chemicals at a maximum allowable annual average level of 80 parts per billion (80ppb) when used in drinking water purification systems, but there are no such controls for household wastewater6. With either a compromised city wastewater system or a rural septic system that could potentially contaminate a well or nearby body of water, these pose significant health and environmental hazards.7

Is There A Better Choice For Cleaning Mold?

Rather than using toxic cleaning products that create harmful fumes (Volatile Organic Compounds, or VOCs) that must be vented to the outside environment or using products that create disinfectant byproducts that are known to be carcinogenic, consider a more eco-friendly alternative.

Hydrogen peroxide, h2o2, can be as effective as bleach in disinfecting a surface but lacks the numerous negative side effects. The reaction uses oxidation rather than a chlorine reaction and produces only water as a byproduct, and no harmful fumes. Hydrogen peroxide, at a concentration of 3%, is effective for killing minor mold growth and disinfecting affected surfaces. It may discolor some materials, so be sure to spot test in an inconspicuous area first. This concentration of hydrogen peroxide is easily found at most grocery stores, drug stores, and of course online. A higher concentration of 7% can be found at chemical supply shops, beauty supply shops, and from online retailers including Amazon, and is more effective, but should be used with caution.

How To Use Hydrogen Peroxide On Mold

A common spray mister cap can be attached straight to the hydrogen peroxide bottle and sprayed onto mold spots. This will most likely generate a fizzing reaction for a few seconds up to a few minutes. Carefully wipe the spots away after the fizzing has subsided and at least 10 minutes have passed, and let the surface dry. If there is still mold visible, or it has left stains, you can repeat the hydrogen peroxide application several more times as needed. It’s advised that personal protective equipment be used when cleaning even minor mold spots, including a proper mask, rubber gloves, and eye protection. While the use of reusable microfiber cloths is advisable in many situations, this is not one of them. The mold should be wiped away with a disposable cloth such as a paper towel, which should be discarded immediately. You will likely want to have a fan operating nearby to help remove any excess humidity, although it is not required for the removal of fumes as there will not be any produced.
