With more information becoming available about electric and electromagnetic fields, it’s become a priority of mine to try to take some reasonable and practical precautions. Having to work on a computer all day, surrounded by computers, accessories, lights, phones, tablets, and chargers, I thought it might be a good idea to, if not too burdensome, sometimes wear a hat that is intended to shield from electromagnetic radiation. I am a bit of a skeptic with things like this, so I purchased an EMF meter. I wanted to get an idea of what kind of buffer it provides with regard to electric fields. While I’m aware that the primary claim of this product is to “protect you from harmful electromagnetic radiationâ€, my hope was that protection from the latter would also provide some practical buffer to just an electric field. To do this, I placed an EMF meter right against an outlet extender next to my desk. The reading was approximately 244 V/m. Then, I placed the cap in between the outlet extender and the EMF meter. The reading went down to 108 V/m. Obviously this is not a comprehensive buffer, but also obvious is the fact that this indeed does do something with regard to shielding from any potential effects of an electric field. For me, this is good enough to go with it. The hat itself is extremely lightweight and I forget I even have it on. It’s certainly better than nothing, and the investment is nominal. Thumbs up on this product.
