Hi All


Sorry for the lengthy first post and use of any non-standard terminology. I'm a bit of a novice when it comes to electronics, hopefully I've done enough due diligence so I'm not asking anything too silly lol ?


I've bought a Grounding mat that plugs into the mains (earth wire only) which I use for grounding my body during the day and overnight. Problem is I'm waking up in the middle of the night and my I feel like i've got an electric charge wherever my body is in contact with the mat. I've only been using it for a few days so far and the seller is saying it'll pass, however i'm not sure. I'm also sometimes getting head & neck in the morning. It's a mat like this one... Grounding mats, Earthing Yoga and Fitness mat - https://www.groundology.co.uk/earthing/grounding-mats.


I've done a bit of research into this and found that it's possible that I've either got electro hypersensitivity, or there could be some electrical interference on the earth in my house (or maybe something else?). I've got a multimeter and have tried to compare the earth with a baseline source (earthing rod in garden) and I can't see much AC current coming off of it, but I do notice that it's frequency is 50hz (I'm in the UK), so maybe it's picking up some EMF or something not sure. I've tested all plug sockets with a socket tester and all seems to be fine, earth is working normally apparently. I've got a couple of options from what I can tell


  1. Find out if the mains is faulty and fix that. Socket tester shows it's clean, so not sure if there's anything else I can do to test this?
  2. Upgrade the cable that I'm using to connect the mains to the mat. Guess it would need to be shielded from EMF and also filter/block out any AC current that might on the mains earth and is leaking onto the mat
    Here is an example of a product that already does this and Video here, but I'm not sure what components would be needed to replicate this. Maybe it's a ferrite core to filter any leaking current? Any recommendations for what shielded cable to use? I guess it's not advisable to use something like speaker cable that can carry too much voltage, for safety reasons? Btw, I'm trying to save money otherwise I'd just buy the example cable above (I'm looking at a multi room setup so would work out a lot)
  3. Fit a grounding rod like this one (3/8in (9.5mm) x 4ft (1200mm) Copperbond Earth Rod with Cable Clamp - https://www.cef.co.uk/catalogue/products/229310) and connect it with shielded cabling into the house
    Can I use thicker cable initially so I can split it and connect up a few rooms (then use thinner (safer) cables to join with connections to the mats)? Again, I'm guessing both types of cable would need to be shielded?

Thanks so much for any help guys! Reason I'm doing this is because I've recently found a skin melanoma and noticed that the EMF levels (high and low) in the house are really high. I'm trying to reduce them all as much as I can


Cheers

Connecting yourself ‘all over’ to the mains earth is not something that I think is wise. I do understand the concept of grounding and what you are hoping to achieve, but the simple fact is the majority of domestic earth installations in the UK are now TNCS where your E is actually the N conductor outside your installation. So your inside E may not be exactly at Earth potential and this defeats the purpose, in my opinion. The next issue - there is a fault which can make N go to a high voltage, which is your E with TNCS, which you are now wrapped up in ... gulp.

For grounding, I enjoy walking about on grass barefoot :)
 
Some interesting information in the 'about' and 'FAQ' sections of that website!

The FAQ suggest every house is TT, I am sure most are TN

If you think it's making you ill, disconnect it, roll or fold it up, and place it in the bin.
Then stay away from pseudo scientific drivel on social media or the internet, placed there by persons whose only interest is in parting you from your money.

Yes pseudoscience springs to mind

Lovely! Thanks for you reply :)

I think options 1 and 2 are redundant given the information you shared, so thanks for helping me with that decision bud. I’ll go with option 3 and create my own earth.

Any advice on what type of cabling I could use to run from the grounding rod into the house and then rooms? Is it safe to use thicker cable for that first run then in each room join it with the cable that comes with the mat? If you know the names for ideal types of cabling to do this, I’ll have a dig around
 
btw there are lots of peer reviewed studies on the benefits of earthing in general but also using mats like this... happy to share if anyone is interested
 
You should avoid bringing an independent earth connection into the house that is not part of the electrical installation. In the event of an electrical fault or accident this can significantly increase the risk of electric shock, because the voltage present on the independent (extraneous) connection will not follow that of the installation and anything bonded to it in the equipotential zone.

Without trying to doubt what you say, if the mat is making you feel ill it is as likely to be due to outgassing from the material it's made of, or something like that, than any electrical effect. You might consider yourself a reliable observer of your experiences, however with a cause (putative noisy mains earth) and effect (a strange feeling in your body) that are so tenuously linked, it is very hard to exclude experimental bias.

Can I recommend a simple, blinded testing method to discover whether the effect you experience is related to the earth connection? It's what I would do in your situation. Leave the mat in place but hide the earth connection to it, so that you can't tell whether it is connected. Get someone you know to go to the connection once a week for a month or two, and leave it either connected or disconnected according to the throw of a dice, keeping a log e.g. 'C' for connected and 'D' for disconnected. You stay out of contact with them, so they won't hint to you about how the connection is set that week. Keep a log of how you feel about the effects, using a simple scale of 1-5. At the end, give your log and their log to another person who knows nothing about the experiment or your concerns, and get them to check for any correlation between the letters and the numbers. It might cost you a bottle of wine for your experimental assistant but could save you a lot of time and effort once you can be more sure whether the effect you experience is actually due to the earthing of the mat.
 
Thanks for the details information Lucien, really appreciated. I agree an A/B blind test would be ideal way of working out what's causing the uncomfortable feeling. I'll consider doing that

Could you tell me your thoughts on this earthing rod which is designed to be used with the earthing mat?

It's 2mm cable is unshielded, however do you think it would be safe to use this earthing rod product in my setup and bypass the mains earth idea? If so, do you know of a shielded cable I could use to perform similar function to that used in this product? That's my main issue as I have lots of EMFs running in the house and I wouldn't want to use this product as there may be interference introduced onto the cable.
 
Lucien beat me to it, but many plastics outgas potentially unpleasant precursor chemicals in their manufacturing process and if you are feeling odd due it its presence, that is FAR more likely to be the reason.

To clarify. The unpleasant feeling is more like i've got micro shocks near where my skin is touching the mat. It's not like toxic poisoning, more electrical. I also get tension in neck muscles and headaches, so I'm assuming it's not related to chemicals etc. The mat itself is made from pure rubber with carbon infused conductive elements, afaik this shouldn't be dangerous

I personally think it could be due to electro hypersensitivity on my part more than anything and the grounding rod solution would stop any issues i have if this is the case
 
If you are getting a tingling sensation, more pronounced if you brush against things, that can be a sign of a faulty earth allowing a few microamps of AC current to flow.

While that current is not dangerous in itself, the whole purpose of having earth (also called CPC here - circuit protective conductor) is to divert fault currents safely and allow the fuse or breaker to disconnect before it is a major hazard. If the CPC is faulty you are a single fault away from a fatal accident!

Having the home wiring checked by a professional is your best option to rule out that sort of thing. Generally this is referred to as EICR - electrical installation condition report. It has become popular recently following changes to landlord rules, etc, so there are a lot of poor players charging little up-front with the aim of making a profit on potentially unnecessary work later. Doing it properly depends on the size of the installation, etc, but would take from a couple of hours to full day and priced accordingly.

There may be someone on here that could quote for doing such a check properly, though expect something like £200 or so.

sorry this post is missing, looks like it needs mod approval so you can't see it
 
If you get shocks touching the mat, and the mat is connected to the means of earthing of your installation, then you should be getting shocks from all your earthed electrical appliances like your washing machine. Regardless, it would imply that there is a fault with your electrical installation and things that should be at earth potential are not. This should be rectified promptly to avoid risk of serious shock injury.

What is the bulk resistivity and/or surface resistivity of the mat? The reason I ask is that many types of earthing mat (such as the anti-static mat on my bench that protects my equipment) are designed to maintain a significant resistance between any contacting object and the mains earth, to avoid risk of shock. Knowing the spec of your mat might narrow down possible causes.
 
It doesn't make sense to use shielded cable for an earth connection, because the main method by which shielding works (e.g. to stop car ignition systems causing crackling noises on your stereo) is to surround the important conductor with an earthed one. So you would be shielding an earthed wire with another earthed wire. There are lab techniques where this is necessary but it is not applicable to your earth mat.

It would be like trying to wash tap water off a surface using tap water.

Thanks bud.

I have a multimeter. If I put the black pin on earth (like metal surface on radiator pipe?) and red pin on the mat connected to the mains, what would I see if the earthing is faulty?

Ah, thanks for the explanation... makes sense

You can't effectively test earthing like that. If the pipe is connected to earth it is likely to be via the earthing system of your installation, so you should not see any significant voltage between the two, or between any two supposedly earthed things. Say less than a couple of volts on the 20V AC range. But it doesn't tell you that the earthing is sound, for that you need the proper test equipment that an electrician would use.

You could however check and post the Ra of the electrode and/or Zs of the supply from the EICR, which would be informative.
 
FYI I just nicked a skewer from the missus and stamped it into the ground outside and connected the mat cable to it. Looks like its earthing correctly. Is there a way to test it? Mat feels different, no more tingling
 
Put meter leads into COM and V/Ω. Set the meter to 200V AC (if it has separate switched ranges). Disconnect both wires from the mat. Connect one probe of the meter to the wire from outside and the other to the wire from your socket that had been used to earth the mat. For your safety, if you are inside, treat the wire from outside as though it were live, and vice versa.

Report the reading. If it is less than 20V, switch down to 20V range. Better still, post a pic of the meter displaying the reading, for an independent observation that it is correctly set.
 
Not sure if I’ve done it right, manual was showing no reading. I switched to auto and it would flash up a value (normally around 42-44) then reset. This is the read I managed to capture

0.08 volts, 80 millivolts. That's the sort of reading I was expecting. There are some caveats about its accuracy but the main one (measurement lead resistance) has been dealt with already when you showed the resistance reading. The other important one is that the meter will be reading only the voltage present at frequencies within its measurement capability, which includes all electrical power lines. However if you were under the mast of a radio or TV station transmitter, that might not be a sufficient indication that there were not strong fields at radio frequencies inducing a voltage that the multimeter cannot sense.

I think you need to look carefully at what other factors could be influencing your sensation of the effects of the mat; they can be real effects, and again I must say I am not doubting what you experience. But 80mV w.r.t. true earth, contacting the body in at one point only and relying on the stray capacitance to earth to complete the circuit, cannot realistically pass enough current to create a sensory effect.

The stray capacitance of a body is typically less than 1nF, more likely around 200pF. It will be less to true earth if part of your environment is shielded from earth by the mat at mains earth. Let's call it 500pF anyway.
At 50Hz, 500pF will have a capacitive reactance of 1/(2*PI*50*5e-10) ~6MΩ
0.08V between mat and true earth gives a touch current between you and the mat of 0.08/6M = 13 nanoamps. I can just about feel a current of 10,000 times that, when concentrated in my finger and I brush it over a surface to maximise the sensory response to muscular reaction (like a dowsing rod). It takes about 100,000 times that current to feel as an actual electrical tingle.

You'll probably still think I'm crazy after watching this, but it could be really eye opening for you too

I will watch the whole thing. I have just watched the first two minutes and counted six factual errors or abstract ideas presented as facts.

I’ve got to ask, can you not just use a piece of rubber mat with no grounding

Thanks for taking the time to work that out for me Lucien, really appreciated. I can't lie though, it will probably take me a couple years before I can understand what was said lol. My high level understanding is that you're saying that any current in the mat caused by connecting to mains earth should be imperceptible based on the readings I've given. I don't doubt your understanding on this subject, but there is definitely something waking me up for the past 3 nights at 5am, 5am and 4am last night. Maybe there's something happening on the system at that time, no idea, but I never wake up before 6:30am! I dunno, I feel like the brother from Better Call Saul!!! :D

I've noted down what you said and will try and get my head around it. Thanks for watching the vid, let me know what you think once you've seen it all. Interested to hear where its flaws are.... cheers again bud!
 
If you are going for earthing to the outside world -- a Volt stick

You'll probably still think I'm crazy after watching this, but it could be really eye opening for you too

I just carried out a quick case study. My son ironically has colic also, so after standing outin my garden for nearly 10 minutes I can confirm that he has not stopped crying or showed any intention of doing so, and the inflammation in my lower back has in no way got any better.
 
Just through pure curiosity and trying to understand why you believe in this grounding, I watched the video and also looked into papers of experiments and claims arising from them.

Noted, the video you posted is full of questionable claims and does make misleading claims, also making comparisons that are simply not connected and even work in different way yet pushes them as though the information matters.
Looking into a few papers of case studies I find they fall far short of any proper experiment, there is no control used, the same experiment was done on one group, they were told what was happening and what the claims are and there was no other groups subject to the same conditions without said information.

Psychological conditioning is already proven to reduce pain, there is nothing in these experiments to eliminate that or confirm it isn't the cause of the perception the patients get about reduced pain.

You say this has been peered reviewed, that means nothing without knowing the results of the peer review, I cannot find any peer reviewed basis to these claims that have been passed and accepted as real results due to grounding, please cite me this peer review you suggest so I can see what the results are of it.

From my life experience and career experience here I cannot believe there is any truth in this, no verifiable and repeatable evidence has ever been submitted, from what I can find where experiments has occurred I conclude they are poorly devised and lack any form of control subject which more or less make them worthless experiments.

It also doesn't give me a lot of positivity about this when the video's main characters have vested financial interests in this idea so the last person you want to trust with your money is the man selling snake oil.

What a load of Drivel this post is only tingling you will get is the removal of money from your bank account by a bunch of scammers selling the product in the first place

Well thats my take

BTW got some super Special bonding clamps that come in pretty colours and cable that is extra bendy
 
Just to add my little bit, I do have a good understanding of many things electrical.
I am not convinced by the video, I have watched it from start to finish.

however, there is some merit in the fact that if you think something is helping/ healing / good for you, It may well do so even if it has no active properties that do so.
the mind is a thing that we do not fully understand (not even close)

Depending on the exact method of grounding (earthing system) at you property, the device itself is in my opinion capable of doing the exact opposite to what you intend.

many homes can sometimes share the same earth cable and each of them will inject electrical noise into it.
some high frequency from power supply's to microwaves and tv's that Simpley cant be measured using a multi meter.
If these harmonic frequency's are indeed being carried by your earthing system then you are sleeping on an inefficient transmitter of them when you plug it in.
although they may not be transmitted particularly well, the fact you are so close to the transmitter will mean that you get a much higher dose than if they were kept in the cables required to supply electrical equipment that are some distance away from you.

Bottom Line,
If my wife gave me a new pillow and i had 2 nights of poor sleep with, it would not be there for the 3rd night.
If she put a different duvet on that did the same, it would have the same outcome.

Under no circumstances would I allow her to put a large aerial under our bed.

something that is supposed to make you better but in fact makes you worse is an item that should be sent back for a full refund ASAP, not given the chance to be tested until it is out of the cooling off period of sale.
 
From all that has gone before I have to conclude that connecting myself to true earth is not going to help with the pain caused by my prolapsed disc and therefore I'll stick with my doctor's prescription of painkillers until I get the operation to sort it out.

Thanks for all the entertaining and educational responses in here. I've been out and didn't expect to have ruffled so many feathers! Appreciate your responses and your taking the time to watch the vid. Sorry I couldn't sway anyone and it was a waste of your time!

I've since built a a contraption with a meat skewer, some phone cable, rubber bands and scotch tape. I've slipped the fandangled cabling through the bedroom window in the hope my missus doesn't see it and get deeply offended at the disharmony it's creating.

I wish you all a good night, please pray for me (i've got a video on that too I can share). You're probably expecting me to be dead tomorrow, so any atheists - please turn to God for me temporarily!!!

Well, I've just forced myself to listen to and watch that link all the way through. A total and utter waste of 15 of the 36 million odd minutes I've been alive!
False associations, pseudo science, unsubstantiated claims by the bucket load, dubious scientific method, etc, etc. interspersed with utter drivel.
 
Managed to watch about half the video, but couldn't get through it all.

It reminds me of a company called PWB, who sell snake-oil type products that claim to improve the sound of your hifi. Have a Google and see what you think. One of their best ones is a small metallic sticker which you place on the door frame, or on a favourite photo. I kid you not. They've been going for years, and I would say they are prime candidates to team up with this guy who thinks taking trainers off can cure MS.

How did you sleep?
 
How did you sleep?
Terribly! However, I was serious about the cabling I used and how it was put together. I did it very late at night, after i had finished my order for the actual parts I'm using.

I tested my cabling in the morning for continuity and there was none lol, so I binned it. Will have a proper setup tonight though and will update again tomorrow... Thanks for asking James

The cable had no continuity? That sounds unlikely, unless it has had some serious abuse.
