Copper mat in bed for EM radiation.

I would rather leave because the additional EM radiation does not bring any positive effects.

What’s happening with lightning?

Depends. The lightning “seeking” tends to be the “shortest” means the most resistant way. A copper mat of course has a very low resistance, but one must always look at the overall path of lightning.

Do you like to sleep outdoors with thunderstorms or why should the lightning strike in your bed?

An earthing is not such a mat. It could be helpful to create a similar potential along your body, but is not a Faraday cage. And she lies under you – if she is over you, where the lightning comes from, the effect would be somewhat greater.

If the lightning hits you in the bed, the mat won’t help you or not much.

When the mat is connected to the door of the house, a blice strike in the vicinity of the house can come very well over the ground to the mat, as with all the Electeo devices that are inserted. It’s called ‘indirect flash’. That would be fatal.

So make sure the mat is not grounded. But then it doesn’t make any sense against EM radiation.

Think a look into the physics books could not hurt here!

  1. You don’t sleep under a tree or under a mast, but very likely in a room. So where’s a lightning coming from? You don’t need to worry about it – as well as out!
  2. Then your probably super expensive copper mat: How’s that going? So in order to shield “radiation” they would have to enclose you – i.e. form a so-called color-day cage – look here: Faraday cage – Wikipedia
  3. Then on the topic of EM radiation in general: There are a lot of opinions on the Internet that claim everything possible – but science is NOT! Sorry, but as long as you don’t live directly under a transmitter or you have exceptional high voltages in the house, this is all humbug and there are no signs in research that a mobile phone or Wlan router would be dangerous for you! Look here: BfS – Reviews and Reviews

Hope could still help you with my assessment. May everyone see how he wants. Greetings

If there is only one placebo, there is no need to form a Faraday caefig 🙂

Your speeches are all right. Except for ‘directly under the sender’. There’s the least the radiation, the most ‘safe’ place.

Neither does a copper mat influence the lightning behavior, nor does it shield anything. Only if the mat was completely surrounded by you, so you would be really shielded.

The mat could focus more on “big rays”. Try Wi-Fi, phone on the copper mat.

If it’s not grounded, nothing happens

Sure? The grounding of electrical devices and metallic objects ensures that potential differences are minimized. No potential = no current = no danger.

Nonetheless, there is no risk of the copper mat, since there should be sufficient distance/insulation to other conductive objects, so that no spark can skip

Electricity always seeks the shortest way. And in the rarest cases, he goes over a bed.

That’s what you’ve got in a flash anyway.

Exactly.

As I said, I cannot say much about the technical/physical subtleties of foundations, depth springs, ringers, lightning protection system on the roof and overvoltage protection type A, B, C. I can ask my experts again on occasion.

I only know grounding/potential compensation is important for the protection of humans and materials.

That’s what you’ve got in a flash anyway.

However, this statement also depends on lightning protection itself. If the lightning protection is placed around the house as a ring and is tied into the potential compensation.

The latter prevents exactly the case you describe.

That’s true. However, it is so: a flash impact increases the electrical potential in the environment for a short time.

All that is well grounded is raised to the same potential.

All that is not well grounded remains at the original potential.

There are thus voltage differences. If the voltage is sufficiently high and the resistance is sufficiently low, the arc/short circuit occurs. This can damage fine electronics or trigger a fire in unfavorable cases.

Now I’m not an expert on lightning protection and earthing. But I know an expert who explained it to me about a long time ago.

So it is not about the entire stream of lightning being able to find a way over the bed, but that a fraction of the lightning current could find a way to cause damage somewhere.

You should connect the mat to the lightning arrester.

Why should a lightning strike – don’t you have a lightning arrester?

Indirect flash can be an oroblem. Then the electricity comes to the house via the grounding line.
