In my article “Earthing and Grounding – Restoring Your Natural Balance” I discussed how the modern lifestyle subjects the human body to unnatural conditions which are potentially harmful to health and wellbeing. When a person is electrically insulated from the ground by synthetic-soled shoes or non-conductive flooring surfaces, and then exposed to man-made electromagnetic fields (EMFs) from electrical and electronic equipment, unnatural electrical currents are created that flow in the human body, which are scientifically proven to have a biological effect – they change the way the body’s cells function, which is not a good thing at all.

We can restore the balance to our body by grounding (also known as earthing), essentially making contact with the ground to bring the body to the same electrical potential as the Earth itself. Grounding or earthing is nothing more than restoring our natural state of being, recreating the natural conditions our bodies are designed to function in. Outdoors, grounding can be as easy as walking barefoot on the beach, on grass or dirt, or being in physical contact with ground in some way or other, as humans have done for millennia.

Indoor locations are a greater concern, because we’re surrounded by man-made electromagnetic fields (EMFs) of greater intensity, and indoor floor surfaces are mostly non-conductive, both exacerbating the problem and making it much harder to ground our bodies. So what’s the solution indoors? Fortunately, there are a range of earthing products available which are designed for indoor use to address this very problem.

One such product is the Earthing Oz – Sleep Deep Pad, it’s a quilted underlay made of conductive silver fabric designed to go on top of the mattress and under the fitted sheet. It comes with a detachable ground cord that connects to ground via the Earth ground port of an electrical outlet or an optional ground rod.

The Sleep Deep Pad fits all sized beds, whether single, queen or king size, and can be placed length-wise down a bed for one person to have their whole body on, or across a bed for two people to share. It’s made with a plush quilted material that feels soft and luxurious, so you won’t notice it underneath you when you’re lying on it. The upper conductive surface which does the work features a unique innovative 100% silver conductive patented fabric that you won’t see on other products.

How does it work? You don’t need direct skin contact with the conductive silver surface for the Sleep Deep Pad to work. The natural moisture of our skin allows conduction through fabrics such as bedclothes and fitted sheets through to the Sleep Deep Pad underneath and into to the ground.

What will this product do for you? Quite simply, it will ground your body, recreating the natural electrical state of the body that you experience when when you walk barefoot on grass, dirt or along the beach, just as Nature intended. The great part is that the Universal Earthing Mat will do this for you while you’re sleeping!

The Sleep Deep Pad will connect your body to the ground electrically, preventing unnatural electrical currents which may affect your health. According to the product description, it will also deliver other observable health benefits:

Medically Proven Health Benefits – better sleep quality, improved circulation and blood flow, relief from pain and inflammation, reduced stress, relief from muscle tension, boost to immune system plus many more benefits…” There is a link provided to read about all these benefits in more detail in the Earthing Oz article Earthing Benefits for Inflammation and Healing – The Ultimate Antioxidant and Anti-Inflammatory which you can check out.

When I test products, I aim to be very thorough in my testing, and in this case, to determine if there are any observable long-term benefits from using the Sleep Deep Pad, I tested the product over a period of three months, so I appreciate the patience of Earthing Oz for the time it’s taken to review their product!

First Impressions & Specifications

When I received my Sleep Deep Pad in the mail, Earthing Oz had thoughtfully packed the product inside a sturdy cardboard box, ensuring that the product was well protected in transit and that it arrived in pristine condition. I really appreciate it when a business goes that extra step for their customers.

Inside the box, the item and its included accessories were packed in a neat and orderly way. The Sleep Deep Pad comes in a clear plastic protective zip bag, and is supplied with a 3.6m (12 foot) grounding cord, an Adapter Plug with built in splitter and instructions.

Unpacking and unfolding the Sleep Deep Pad, you realize it’s is quite a decent size, measuring 45.7cm (18″) x 90.2cm (35.5″). It has a nice soft, plush feel, and appears very well made. It’s also machine washable, making it very easy to clean.

The Sleep Deep Pad has a multi-layer quilted construction, with a conductive silver top surface, and an underside made of a durable grey fabric. The polyester batting in-between provides the padding and gives the soft, luxurious feel. The stitching is nice and tight, perfectly straight and even, and looks really well done. Overall the Sleep Deep Pad definitely looks like a quality product that is made to last.

According to the product description, the Sleep Deep Pad uses a new 100% silver conductive patented fabric, which is made from 50% polyester and 50% nylon tightly woven together and then metalized (dipped in silver). This process bonds the silver with the nylon in the fabric giving coverage across the entire surface area of the fabric. Metalizing the fabric increasing the amount of silver in the product, creating a more effective conductive surface compared to other products which just use silver thread woven through the fabric.

Here is a close-up of the fabric, you can clearly see that the the silver coverage is 100% across the surface.

If I’ve understood the product description correctly, because of the complete coverage of the silver surface, less body oils build up on the silver fibres, which means less washing and ultimately less wear and tear, which makes for a longer lasting product. Also, it’s worthwhile to mention the great benefit of the precious metal silver is that it’s anti-bacterial, and since the Sleep Deep Pad is constructed of real silver, this product also shares that property.

The Sleep Deep Pad connects to the earth with a grounding cord. One end of the grounding cord has a press-stud clip which snaps onto the pad and the other end of the grounding cord connects into an electrical outlet via the included Adapter Plug or to the optional earthing grounding rod system.

The Adapter Plug has a built in splitter, which allows you to connect a second earthing product to the same power outlet point, saving space on your wall points and saving money if you want to purchase and use other products like this one in the same room.

The grounding cord is a very generous length at 3.6m (12 foot) and will reach from a power outlet to almost any other point in an average-sized room. Another nice touch is the quality of the wire used on the grounding cord, it’s light but very sturdy, and the insulation is a white glossy plastic tangle-free plastic, like that used on decent quality headphones but much thicker and stronger.

Also included in the box is very clearly printed and well written ‘Usage, Care & Safety Instructions’ sheet. You can click on the image to view a larger version. The reverse side of this sheet includes additional general information which is applicable to all grounding/earthing products.

My initial impressions are that this is a quality, well made product with some unique features to differentiate it from competing products.

Next we’ll set up the product and test it to see how well it does what it’s supposed to do, ground you!

Setting Up the Sleep Deep Pad

Setting up the Sleep Deep Pad is very quick and easy, you can set it all up in under five minutes.

Here’s how to set up the Sleep Deep Pad in four easy steps:

  1. Place the Sleep Deep Pad on your mattress under the bed’s fitted sheet, with the bright silver side facing up.
  2. Clip the round press-stud end of the Grounding Cord to the Sleep Deep Pad.
  3. Plug the long end of the Grounding Cord into the Adapter Plug.
  4. Plug the adapter plug into a power outlet or power board.

In the picture below, everything is connected and ready to go!

Tests and Measures

In these tests, we’ll start by testing the individual components first, then we’ll connect them all together as described earlier and conduct our performance tests.

Testing the individual components, we’ll begin by looking at the Grounding Cord. With a multimeter set to the Ohms range (electrical resistance). we can measure how well the Grounding Cord conducts electricity.

The resistance reading is 98.1 kilo-ohms, so the grounding cord clearly has an internal resistance of around 100k (100,000 ohms). This is an additional electrical safety measure to limit current to safe levels if there was some unlikely major disaster with home mains wiring which the earth leakage detectors in the home fuses box should prevent. Having this backup safety measure is an excellent idea. How well will this safety measure work? Using ohms law, V=IxR, this will limit the current to 2.4mA in a 240V mains system such as in Australia, and to 1.1mA in a 110V US mains system, well below the level that will cause electric shock.

The next component to test is the Adapter Plug which has a built in splitter. For safety, the Live (Active) and Neutral pins are made of plastic and therefor cannot conduct any electricity at all, the only conductive pin is the Earth (Ground) pin. On the top of the plug are two points or sockets for the grounding cords to plug into, allowing two grounding products to be connected to one mains outlet at the same time. These two connection points are 5mm wide sockets (a bit over 3/16”) which take the proprietary plug of the same dimensions found on one end of the grounding cord.

The Adapter Plug pictured below is compatible with an Australian mains plug, it’s also available in many other formats such as US, UK, Europe, Danish – Type K and Israel -Type H.

If we test the Adapter Plug for electrical conductivity, we find that the Earth (Ground) pin is simply connected directly to the two grounding cord connection points as expected.

Now that we’ve looked at all the individual components, it’s time to connect them together see how well they work!

In this test I’ve once again set the a multimeter set to the Ohms range (electrical resistance) to measure how well our product conducts electricity.

I’ve connected the the multimeter’s ground (black) lead to the second grounding cord connection point on the Adapter Plug, and touched the multimeter’s red lead on the surface of the Sleep Deep Pad. What we’re doing is measuring how well the connection from the mains power outlet Earth pin to the Sleep Deep Pad’s surface conducts electricity.

Results of first test:

Our connection from the Sleep Deep Pad’s surface to ground has an electrical resistance of 98.1k, exactly the same as the safety resistance of the grounding cord, showing that we have a perfect electrical connection to the ground.

It bears mentioning that when I placed the multimeter probe down on the silver surface of the Sleep Dee[ Pad just to put it down, it instantly established a perfect electrical connection without having to press it at all! I’ve heard and read that silver is very highly conductive, I didn’t realise it was that conductive! So yes, the product will definitely connect you to the ground electrically, there’s no doubts about that!

The testing doesn’t end here though, we still need to determine whether the Sleep Deep Pad can reduce the stray electricity that unnaturally flows through our bodies when we’re exposed to man-made electromagnetic fields (EMFs), which leads us into our second phase of testing.

Performance Testing

In this test, standing in front of my bed on a polished wooden floor with rubber-soled shoes on (meaning that I’m very well insulated electrically from ground), I will measure the voltage produced in my body through exposure to EMFs created by the surrounding electrical equipment and wiring, then I’ll rest my hand directly on the Sleep Deep Pad to ground myself and observe if the voltage in my body drops.

Testing the body voltage is fairly straightforward:

  1. Set the multimeter range to a low AC Volts range
  2. Connect the multimeter’s ground (black) lead to an Earth/Ground connection (such as the grounding cord connection point on the Adapter Plug)*
  3. Touch the tip of the red multimeter lead with your fingers and read the AC voltage on the multimeter display.

* SAFETY NOTE – DO NOT push the tip of the multimeter lead directly into any power outlet to get a ground connection from the Earth/Ground pin, because if you accidentally put it into the Live or Neutral pin holes, YOU”LL GET ELECTROCUTED or damage your multimeter!!!

NOTE: You can get a safe ground connection by connecting the multimeter’s ground (black) lead to a tap/faucet, metal kitchen sink, copper water or gas pipe, a metal rod pushed into the dirt, or on the outside of your computer or other electronic equipment, any bare metal surface or screw, usually found on the back.

With the multimeter’s common lead connected safely to ground via the Adapter Plug, and my hand holding the tip of the other lead, my body is flowing 2.778V AC through it!

Now, resting my hand on the Sleep Dee[ Pad, the voltage in my body drops down significantly from 2.778V AC to a just 0.286V AC, that’s almost a 90% reduction.

In the product description it states that direct skin contact is not required with the Sleep Deep Pad for it to ground the body, that it will work through a fitted sheet or clothing layer because of skin moisture. No problem, we can test that too!

To replicate actual sleeping conditions, with my cotton pyjama pants on (pardon the bare feet!) and resting my clothed legs over the Sleep Deep Pad, my body voltage drops from from 2.778V AC to 0.373V AC. That’s a significant 86% reduction in body voltage. The photo was taken around 30 seconds after I placed my legs across the Sleep Deep Pad, so what little moisture was there seemed to do a great job grounding my body.

Curiously, what I did notice was that the longer I stayed there, the more my body voltage dropped. After a minute, my body voltage dropped from 0.373 V AC to 0.347V AC and progressively dropped second by second at a relatively slow rate. I can only assume that this to be due to increasing skin moisture levels in the layers of fabric (my clothing) sitting between my skin and the conductive silver surface.

There is obviously a limit to how low the recorded body voltage can drop. Once there is enough moisture present to establish the best conduction possible, body voltage could theoretically be reduced to almost the same level as when making direct contact with the conductive silver surface of the Sleep Deep Pad without a layer of fabric in-between.

From this test we can conclude that the Sleep Deep Pad can ground the body without direct skin contact as claimed. With a layer or two of fabric over it (such as a fitted sheet and pyjamas), this test shows that it works perfectly well.

Results of second test:

In this test, the recorded body voltage of 2.778V AC dropped to 0.286V AC, an almost 90% reduction, when I made direct physical contact with the Sleep Deep Pad. With indirect skin contact (wearing pyjamas), the recorded body voltage of 2.778V AC dropped to 0.347V AC, an 86% reduction. As we can see, there is little difference in the results between direct and indirect contact through fabric such as clothes or sheets. We can definitely conclude that the Sleep Deep Pad does in fact reduce the body voltage created by EMFs.

So far the test results are excellent, but there’s still a third phase of testing to do to determine if the user of the product will feel any noticeable difference over the long term.

Long-Term Testing

At the beginning of this product review I stated that for the sake of thoroughness, and to determine if there are any observable long-term benefits from using the Sleep Deep Pad , I tested the product over a period of three months. The great thing with testing sleeping products is that you can literally do it in your sleep!

Results of third test:

Over this extended testing period, like most people, I experienced a whole range of things in my life, a mixture of the good, the bad and the bewildering. The events of our daily lives do have a significant impact on the quality of our sleep, so there was plenty going on to provide a good basis for comparison.

The outcomes of the long-term testing were the most interesting and convincing for me personally. So, what were my findings? Using the Sleep Deep Pad, I clearly felt a noticeable difference to my sleep. I definitely slept much better and woke up feeling much more refreshed, and I would attribute these benefits to being grounded while asleep. I honestly feel that I even slept better the first night I tried the Sleep Deep Pad. Even when sleep was cut short by late nights, or disrupted by the incessant mental chatter which we all experience when we’re unsettled in our thoughts and feelings, I didn’t’ feel as tired in the morning as I normally would. Impressive? Yes, maybe, but consider that all we’re really doing here is restoring the human body’s natural conditions that it’s evolved to function best in, so there shouldn’t be any surprises here that we’re seeing these benefits.

The product promises the long term benefits of “better sleep quality, improved circulation and blood flow, relief from pain and inflammation, reduced stress, relief from muscle tension, boost to immune system” which are the the general benefits attributed to earthing/grounding. During the course of testing this product, I managed to inflame a shoulder rotator-cuff tendon and catch a cold, but since I used a range of therapies to address these conditions and recover, it’s hard to objectively say to what extent sleeping grounded assisted in my recovery. That said, logic and reason would tell us that once the body is given the environment and conditions it naturally requires, the body can heal itself, healing and recovery can then take place unhindered. I would say it’s common sense, just like maintain a warm body temperature to get rid of a cold faster. Hippocrates, the father of modern western medicine once said “The natural healing force within each of us is the greatest force in getting well.” When it comes to health and wellbeing, when we give our body what it needs, it usually takes care of the rest.

I’ve never seen an illness where the recommended recovery treatment is to electrically insulate the body and subject it to random electromagnetic fields which interfere haphazardly with biological processes – so by not doing this unnatural thing to the body, and keeping it grounded, which is the body’s default natural state, it would follow that recovery can proceed naturally, unimpaired by external man-made detrimental influences. I understand that earthing/grounding has been used in professional sports to aid recovery, where they use what works regardless of opinion, so it would be reasonable to conclude that recovery from an inflammatory condition and temporary illness may have been assisted by sleeping grounded, but that is my opinion based on logical analysis.


The Sleep Deep Pad is a great product which I thoroughly recommend, I’ve felt a real difference using it, sleeping better and waking more refreshed. After testing the Sleep Deep Pad I’m convinced that earthing while sleeping aids recovery. Why this product? It’s a quality, well-made, earthing/grounding undelay with a unique patented silver surface that makes it longer lasting and easier to care for. Considering that we sleep for around one-third of our lives, reducing the harmful effects of EMFs during sleep time can make a significant difference. If you only use one earthing product, this would be the one to go for!
