Microbes at Home Affecting Your Health

Mounting Research Reveals the Power of Home Microbes

As we spend around 90% of our lives indoors, it’s fascinating to learn that our homes are not just shelter but also a thriving ecosystem of microbes. The indoor microbiome, as it’s called, is made up of bacteria, fungi, viruses, and other microorganisms that inhabit the very places we live, work, and study. As researchers delve deeper into the indoor microbiome, it’s becoming increasingly clear that these microbes have a profound impact on our health and wellbeing.

The Microbial Community

The indoor microbiome is significantly influenced by human activities. Cooking, cleaning, and even having pets all shape the microbial populations in our homes. Moreover, the design and operation of buildings also play a crucial role in determining which microbes thrive indoors. For example, the type of ventilation system, natural light exposure, and construction materials used can either promote or inhibit the growth of certain microbes.

The Impact on Health

The indoor microbiome can have both positive and negative influences on our health.

On the positive side, exposure to a diverse range of microbes can boost our immune system, especially during childhood. This idea is rooted in the hygiene hypothesis, which suggests that early exposure to microbes helps train the immune system to distinguish between harmless and harmful agents. This may reduce the likelihood of developing certain allergies and autoimmune diseases.

Exposure to microbes may also bolster the immune system against common respiratory illnesses like colds, flu, and bronchitis.

However, exposure to certain microbes can also have negative consequences. Certain indoor environments – particularly those with poor ventilation and high levels of moisture – can harbour harmful pathogens. Damp and mouldy conditions, for instance, are associated with respiratory issues like asthma and allergies. Poor ventilation may also allow common respiratory illnesses to spread more easily.

Furthermore, the use of antimicrobial cleaning products indoors may inadvertently make it easier for antibiotic-resistant bacteria to thrive – posing a significant public health risk. When bacteria are frequently exposed to antimicrobial cleaning products, they develop crafty mechanisms that help them survive and thrive even when these products are used in the future.

Creating Healthier Spaces

Growing evidence suggests that designing spaces to intentionally shape microbial communities can promote wellbeing.

One strategy is to use natural materials, such as wood, which can harbour beneficial microbes. Another approach is to design ventilation systems that enhance microbial diversity. For instance, buildings could feature living walls with diverse plant and microbial life, or use building materials embedded with beneficial bacterial spores that can be activated when needed.

Probiotic cleaning products, which introduce beneficial microbes into the environment, are also being explored as a way of out-competing harmful pathogens and promoting a healthier indoor microbiome.

Indoor plants can also contribute to a healthier microbial environment. Plants not only purify the air but also cultivate diverse microbial communities indoors.

Conclusion

The indoor microbiome is a crucial, though often overlooked, aspect of our living environment. As our understanding of the indoor microbiome deepens, the potential to design spaces that enhance our health becomes increasingly feasible. The challenge now lies in making these advancements accessible to all – ensuring everyone can have a healthy indoor microbiome, regardless of their socioeconomic status.
