EMFs & You: What They Are & How to Reduce Exposure in Your Home

Have you ever wondered about the invisible energy fields buzzing around us? 

They are called electromagnetic fields - otherwise known as EMFs - and they play a big role in our modern world. And in the way we live in our homes.

So how can you take them into consideration and take actions to reduce your exposure?

In this article, we'll explore what EMFs are, how they might affect us in our homes, and some simple steps you can take to create a more comfortable home environment and reduce your EMF exposure.


What are EMFs and are they harmful?

EMFs are invisible areas of energy created by electrically charged particles. 

They come from many sources and they are all around us. They are mostly noiseless and they are odourless, and invisible.

They exist naturally, like the light and warmth we get from the sun. But they're also produced by man-made sources like power lines, appliances, and wireless technologies like Wi-Fi routers and mobile phones.

The key thing to understand is that EMFs exist on a spectrum.

At one end, we have low-frequency EMFs like those from power lines. On the other end, high-frequency EMFs like X-rays that carry more energy and can be potentially harmful. 

The EMFs we typically encounter in our homes fall under the low-frequency category.

Should you be worried about exposure to low-frequency EMFs?

The science on the health effects of low-level EMFs is still evolving. 

While some studies suggest a possible link between EMFs and certain health problems, others haven't found conclusive evidence.

But we are seeing an ever-expanding number of smart home devices that will all contribute to our exposure to EMFs. And it’s important to take into consideration how the way you design your new home build or renovation might help reduce the frequency with which your family comes into contact with EMFs. 

How Smart Homes are increasing our exposure to EMFs

There is little doubt that advances in technology have benefitted the human race in ways we had once only dreamt of.

We have apps for every imaginable use, and wearable technology that helps us track our body’s functions.  

On the medical front, patients can be monitored from afar. 

Smart homes are becoming increasingly popular, and with good reason. They offer convenience, automation, and improved energy efficiency.

And there’s no doubt that for people with a disability, homes that leverage technology have the capacity to make great changes to their lives, such as giving them control over door hardware, room temperature, lighting, window furnishings, nurse call, and emergency services, all from a tablet that can be voice operated.

However, these benefits all come with additional sources of EMFs. 

Smart devices like voice assistants and wireless thermostats, baby monitors, security and irrigation systems, all constantly emit low-level EMFs.

How can you reduce exposure to EMFs in your home?

Even though it’s not yet clear how EMFs impact our bodies, sleep and wellbeing, there are steps you can take to create a more comfortable EMF environment in your home - 

Distance matters: EMF intensity weakens with distance. Consider placing your Wi-Fi router in a central location away from frequently used areas like bedrooms.


Turn it off when not in use: When you're done streaming or using your smart devices, consider powering them down to minimise ongoing EMF emissions.


Wired connections: Where possible, choose wired ethernet connections for computers and entertainment systems instead of relying solely on Wi-Fi.


Embrace the natural world: Sunlight is a natural source of beneficial EMFs. Don’t forget to step outside and connect with the earth’s natural energy.

By understanding what EMFs are, and by taking these simple steps, you can create a comfortable and healthy home environment for you and your family.
