While electromagnetic radiation (EMF/EMR) is very complicated, and understanding it can be quite difficult, it is actually quite easy to learn how to reduce your personal risk from EMF exposures.
There are two basic rules, to reducing your personal exposures to EMF (and thus, your personal health risks that stem from such exposures).
- MINIMIZE your use of EMF-generating technologies.
- MAXIMIZE the distance between your body, and the EMF-generating technologies, when they are in use.
The first point, to minimize your use, is quite simple and obvious. After all, the best way to minimize your exposures is to minimize your use of the tools that generate these exposures.
All modern technology that utilizes wireless communication (from radios to WiFi routers) emits electromagnetic radiation. Also, any appliance that runs on AC power (i.e., plugs into the wall) also generates non-ionizing EMF. We are increasingly surrounded by these technologies, which tend to be on even when we are not using them. Use these devices only when their use is required, and turn them off when you are not using them. As a basic example, do you really need your WiFi router on at night, when you are asleep? This simple step will reduce your personal exposures to EMF.
The second point, the maximize distance, may be a bit surprising. This is because the power of EMF radiation not diminishes with distance— but does so exponentially.
This means that every little bit of distance that you can create between yourself and the source of the EMF emissions will reduce your personal exposure to the EMF radiation that stems from these devices.
This is why wired headsets for cell and cordless phones are recommended— precisely because they allow you to keep the phone further away from your brain, and your body. This is also why pregnant women are encouraged from standing several feet away from microwave ovens when they are in use.
