Try to minimize the metal in your sleeping area…
you’ll be glad you did. :)
What else is there???
Well, there’s wood and plain old foam and air…
yes, air beds… but the ‘automatic inflation” ones
have to be very nasty, EMR-wise.
I think you should minimise the electricity in the room you sleep. Always turn it ALL off with 2 pole switches on the mains fuse box. Ring mains are heavily implicated in many disorders. There MUST be no AC. I only use DC. AC stinks with radiations even when you are not using it. DC has no fields.
Metal in a bed is only a problem if it induces current which you would too if you are close to AC. Your blood made of magnetised iron pulses at 50 or 60HZ.
I have a Faraday metal box and sleep in nearly 0 rads. I have never felt better. I feel young again. Try it.
Your biology repairs its self at night because it was before man, 0 radiations. This is crucial for accurate reproduction. Maturation in radiations causes inappropriate identification and effectively addiction to non human signals.
