Being stuck inside drives many of us to more TV, video games or playing on the phone. What all of those have in common is the length and proximity we are exposing ourselves to electromagnetic waves (EMF).
EMF waves are generated from anything electronic, either plugged in or powered with a battery. The higher EMF emitters are microwaves and anything that pulls an internet signal (like a smart phone).
The best line of defense - distance. The farther you are physically from that item, the less powerful the wave. Especially at night - take the laptop and smart phones away from the bedroom.
Next, consider EMF protection products. These are available for the entire home (here) or for a specific use. Check out the cell phone protection products (here) and personal jewelry (here).
