Hi Guys,

One of our users sent me a fascinating paper written by Joel Moskowitz, a researcher in the School of Public Health at UC Berkeley, about the dangers of cellphone radiation (LINK HERE). They asked me if it is possible to physically cut off their phone’s ability to communicate with anything, including Wifi, Cellular, Bluetooth, NFC (near field communication), etc.

The reason is so that when they are in bed sleeping, they are not being exposed to radiofrequency radiation or radio waves emitted from their phone lying right beside their head. The answer is yes, and it is straightforward to do.

Most people do not know this, but their smartphone always communicates with other devices nearly all of the time, even when they are not using their phone. If it is not the Wifi checking for nearby hotspots, it is the Bluetooth trying to pair with new devices or maintaining existing connections. Or it could be any installed application making a connection to update itself or upload/download data.

As per the article, it looks like it is terrible to leave your phone beside your bed when you are sleeping as it can cause headaches, etc. I would recommend that you either power your phone off completely or leave it in a different room, but if you need to hear your alarm clock, you can make yourself a homemade Faraday cage.

To make your homemade faraday cage, you need to get some aluminum foil and some plastic bags and follow these easy instructions from the guys at WikiHow https://www.wikihow.com/Make-a-Faraday-Cage. It is almost effortless to do and will take you 10 minutes.

Essentially if you wrap your phone in layers of plastic and foil, you can kill its ability to communicate with anything in any way. The foil blocks anything from coming in or going out. Please be advised, though, that once you put your phone into this ‘cage,’ it will not be able to receive phone calls or surf the internet. Your phone will not be able to communicate in any way.  Do not do this if you need to receive calls or messages during the night.

Don’t worry, though; you will still be able to hear your alarm clock as sound is not restricted. When you wake up, you can take your phone out of its new ‘sleeping bag,’ and it will be working perfectly.

I hope that this tip is helpful to you and if you need any help, let me know.
