Electro-smog Shielding Bag

Posted on 2012-09-15
Last Modified: 2012-09-15
My wife keeps near the bed 2 phones and a tablet, which stay on all night long. She refuses to turn them off because they take too long to power up when she needs them during her brief wakes... (please don't say anything).

Since the jury is still out on the potential bad effects of electro-smog, and she is showing some signs of disturbance, my idea would be to find some sort of an insulating bag in which she could put the stuff. This way, when she needs it, she just takes out whatever device, wait a second or 2 for the network signal to be re-established, and everybody is happy.

Do you know if such container is available on the market? What would be its correct name?

    The easiest thing is to move them to the other side of the room.  That will reduce the exposure by the square of the distances.

    aluminium foil as you probably can find in your own kitchen should work

    actually anything that is metallic should work

    you can easily test what works and what does not just be checking that your phone/tablet is off the network.


    shielding the bottom part of your bed, probably won't make that much of a difference, but it may feel more secure


    beware that re-establishing the network should take more than 2 seconds

    beware as well that the phone will use the maximum available power when you remove the lid because it adjusts the power depending on the quality of the network.

    for this same reason (and the fact that the device will spend more time searching for networks), using such a setup will use up the battery quicker, but still much less than while talking.

    wifi brings much more exposure than the phone


    bottomline would be that you probably should not care about the phone : as long as the reception is good and the phone is 1 meter or farther away, the exposition level still should be much greater than what the environment would produce, but hours of exposition at this level still is less than a few seconds of phone-to-ear communication

    You also probably should make sure the wifi signal is good under your bed so the device does not emit more than needed, or much simpler, deactivate the wifi on the tablet when you are not using it. i believe setting it up to sleep when it is not used is a good and simple way to acvhieve this
