children lay in the grass earthing with barefeet

Grounding Q & A

By Stephen T. Sinatra, M.D., F.A.C.C., F.A.C.N., C.N.S., C.B.T.

Since grounding (as we know it today) is so new to medical science, and doctors have only recently started tapping into grounding’s potential health benefits, people all over the Internet have questions about grounding (a.k.a. “Earthing”). We hope to help answer some of them on this page.

Do you have a question about grounding? Send an email to [email protected] and we’ll do our best to post a response on this page.

Q: So what is Earthing?

Earthing, otherwise known as grounding, is the process of reconnecting to the Earth’s subtle, natural, electrical energy. This is easily done whenever you walk barefoot in the grass, sand, dirt, or on concrete. When touching the Earth, its energy flows directly into your body bringing you back to your most natural electrical state. This is the electrical state that humans experienced throughout evolution when we lived in direct contact with the Earth. As civilization evolved, we started to wear shoes. Leather soled shoes allow a small amount of energy to pass through the sole but rubber will not let any energy transfer from the Earth into your body so for most of us today, we are literally disconnected whenever we walk on the Earth. Earthing is all about reconnecting!

What is Earthing or Grounding?

Q: Is Earthing based on science?

Absolutely! Earthing is based on physics, physiology, and biology! Our bodies are electric. Energy fills us and surrounds us. The Earth’s subtle energy is different than man-made electricity that flows into outlets. Man-made energy produces electro-magnetic fields (EMF’s) that are unnatural to our bodies. The Earth, on the other hand, pulses with a gentle flowing energy that harmonizes all of the life on Earth including you! Earthing brings you back into synch with this energy and back into electrical balance. Learn more: Earthing research and studies.

Q: What are Earthing devices?

Earthing devices are simple, conductive items that you can use in the comfort of your home to connect to the Earth’s energy. They are “barefoot substitutes.”   These products consist of patches, bands, mats, sheets  or mats for the bed, a throw, and a plush pad for animals. All products connect to the Earth’s energy via the ground port of home/office electrical outlets or through the use of a ground rod system. Once connected all you have to do is have direct skin contact with the products so that you can absorb the Earth’s energy. More information about grounding devices may be found at

Q: What are the health benefits of Earthing?

A dozen research studies and hundreds of anecdotal stories have reported health benefits such as reductions in inflammation and pain, blood thinning, improved circulation, improvements in blood pressure, shifting of the nervous system from stress mode (sympathetic) to calming mode (parasympathetic), and improvements in anxiety and sleep quality.

How Earthing Benefits the Heart

Q: How long do I need to be grounded to get benefits?

Grounding to the Earth changes your physiology immediately. The more you ground, the more you can benefit because you are at your most natural electrical state when connected to the Earth. Your body is electrically balanced and flooded with free electrons that help to counteract the non-stop accumulation of free radicals that are created in the body from normal metabolism and life’s stressors. Absorbing electrons from the Earth is giving your body a big dose of “vitamin G.” The Earth is the biggest antioxidant there is, so “the more the better.”

Q: Do Earthing products use electricity?

No, while Earthing / grounding products plug into the ground ports of electrical outlets, they do not utilize any electricity. They conduct the Earth’s natural energy which flows through the ground wire of grounded outlets. More information about grounding devices may be found at

Q: What if you’re in a city [and don’t have access to a lawn or other ground to put your bare feet on]? Can you get the same results from concrete?

Yes, as long as the concrete is not painted or otherwise sealed. Concrete is a conductive substance made of water and minerals. It sits on the Earth and retains moisture. So free electrons will pass through just as they will if you are sitting or standing on grass or open ground. Asphalt, on the other hand, is made from petrochemicals, and is not conductive. Neither are wood, vinyl, plastic, or rubber surfaces, which insulate rather than conduct.

Q: If I take off my shoes, but leave my socks on, will that interfere with the earthing process? Also, if I wear rubber flip-flops or beach sandals, does that prevent me from grounding? I know grounding completely barefoot is ideal, but sometimes the places available to me do not look sanitary.

Cotton socks and nylons are okay (especially if your feet sweat, which will enhance conductivity), but grounding barefoot is best. Rubber and plastic are non conductive and insulate, so regular flip flops will prevent you from grounding. Shoes/sandals made solely from leather or hide will still conduct the Earth’s natural electromagnetic energy, though.

Q: Can I receive grounding energy through ceramic tiles?

It depends on what the tiles sit on. If they are on a concrete slab or on the ground, the energy could come through. If the tiles are atop plywood or some other kind of wood, plastic, or vinyl understructure, they will not likely be conductive. The type of tile also factors into the mix: ceramic tile with a glazed finish on the surface will, like glass, probably prevent the Earth’s energy from coming through.

Q: I have a concrete floor in my garage, but I remember seeing insulation and maybe a plastic vapor barrier put down in the foundation before the concrete was poured…would that concrete floor still provide earthing benefits? What if even part of the concrete went all the way into the Earth?

If there is insulation, and perhaps a plastic barrier before the concrete was poured, the concrete will very likely not be conductive. If however, some of the concrete slab does come in contact with the Earth, then the whole slab will very likely be conductive.

Q: How long should a person ground outside barefoot to notice relief from rheumatoid arthritis and how long for anxiety?

The easy answer is, “as long as it takes.” Grounding benefits are particular to the individual, that is, the amount of time it takes to experience relief of anxiety or inflammation-related pain symptoms differs from person to person. Some people report feeling better after just 20 minutes of grounding, and research has shown physiological changes and significant improvements in the body’s electrical activity after 30 to 40 minutes.

For people with chronic conditions, it may take longer to experience relief of symptoms such as arthritic inflammatory pain; relief may be significant, overnight, gradual, total or partial. Generally speaking, benefits of grounding are dose-related – that is, the more time spent regularly grounding, the better one’s chances of symptom relief.

Grounding may catalyze relief of anxiety more quickly than rheumatoid arthritis (RA) pain relief. Grounding helps create nervous system balance, and lessens stress, by inducing parasympathetic nervous system activity (relaxation response).

People with RA have reported experiencing moderate to significant pain relief and improved mobility after sleeping grounded for a few weeks (using grounding bed pads or sheets).

Top Reasons to Go Barefoot this Summer!

Q: I made a simplified grounding device from copper screening soldered and crimp connected to 14 guage copper wire and the other end of the wire ground connected to a copper cold water pipe in my apartment which showed in electrical testing to be a good ground. I am just beginning to try it out. I was nervous about using the old electrical system in my place to ground anything (3-wire late 1950s or early 60’s wiring only partly updated). Any ideas or recommendations?

You can ground to a cold water pipe, to a ground rod (planted directly into the ground), or to the ground port (third hole) in a grounded electrical outlet, if, of course, it is grounded. You can use copper wire and wrap it around your ankle or wrist, or do what you are suggesting. But you may not find it comfortable, and we are not sure about what happens, toxicity-wise, with long exposure to oxidized copper.

As a general policy, in the interest of safety, HMDI does not recommend the use of homemade grounding devices. If you’re unsure as to whether your house is sufficiently grounded, you might have a professional grounding technician / electrician check your electrical ground system. More information about grounding devices may be found at

Read “The Global Phenomenon of Earthing,” as published in the Winter 2012 issue of Going Organic Magazine.

Q: I was using a grounding mat and a grounding rod with a cord running outside, but started feeling very buzzed and often got flu-like symptoms afterwards. I am EMF sensitive – can you tell me why I feel this way when I ground?

Occasionally some “electro-sensitive” individuals report feeling strange energy (even a “buzz”) when they start grounding. The energy they feel when grounded is simply the natural, subtle, electric field that is eternally omnipresent on the surface of the Earth. If you walk barefoot on the ground your body receives that same energy. Although humans have evolved in direct physical contact with this energy throughout time, most people in our modern society are insulated from the Earth’s energy. We no longer walk barefoot on the ground. So reconnecting with the Earth’s energy can feel strange for some people, particularly if they are ultra sensitive. We generally describe this kind of reaction in non-electro-sensitive people as detoxification.

In most cases, this feeling is temporary, and goes away as the body becomes accustomed to the Earth’s natural energy. If the feeling is too uncomfortable, stop grounding. Resume, if you wish, in a day or two by spending 15 minutes or so barefoot outside or in contact with the Earthing mat inside your home. Then very slowly increase your exposure. In this way, you may be able to work your way gradually to using the Earthing mat longer. Just go slowly and at your own pace. Some electro-sensitive people have found that they receive positive benefits just from minimum exposure to Earthing. HMDI generally recommends that electro-sensitive people use a grounding rod (which is planted directly into the ground), as you are doing, rather than the grounding port in a 3-prong electrical outlet.

Q: This question is about grounding sheets. I had an electrician come to my home and ground my bedroom, so that the tester that comes with the bed sheet now tests grounded. My bedroom is not on the first floor, though; it is over a basement. Should I, instead, connect my sheets to a grounding rod that extends from my bedroom window, rather than use the grounded wall outlet in my bedroom.

A: It’s great to hear you are trying to sleep grounded! If the tester showed that your bedroom outlet is grounded, then you should be fine. Since the grounding rod is planted directly into the Earth, it is the closest means of accessing the Earth’s natural energy next to standing barefoot on the Earth’s surface. However, unless you are electro-sensitive or live in an ungrounded home, we recommend using a grounding device with a rod or outlet interchangeably.

Q: Will grounding help me recover from adrenal exhaustion? I have low cortisol…

A: Adrenal exhaustion can result from being chronically stressed, whether from work, financial problems, family issues, physical disease, insomnia, nutritional deficiencies, and other sources of psycho-emotional stress (i.e. excessive worry, fear, or anger). Our bodies are designed to react to acute stressors with a surge in adrenaline (epinephrine) and cortisol, which assist the body in the “flight or fight” sympathetic nervous system response. When acute stressors become chronic stressors and cortisol levels stay elevated, this puts pressure on the adrenal glands to produce more cortisol. Over time the adrenal glands get “burned out” and are not as effective in producing cortisol.

Grounding can certainly help one recover from adrenal exhaustion. By bringing the body into a more parasympathetic state, grounding can ease the stress on the adrenal glands. Sleeping grounded has been also shown to help normalize cortisol levels. Full recovery from adrenal exhaustion, though, will probably require integration of additional strategies such as stress reduction, nutraceutical therapies, developing a regular, manageable routine, and lots of sleep.

Q: If I am standing on the ground barefoot or in leather-soled shoes and I touch another person with both of my hands…will neutrons pass into their body?  What if they are wearing rubber shoes?

A: If you are standing on the Earth barefoot or in leather-soled shoes (without any other substance in the sole to disrupt conduction, such as rubber) and touch another person, negatively-charged electrons will pass from the Earth through your body and into the other person. If you are electrically grounded (touching the Earth) and you hold hands with another person, they will become grounded as well. Since the body is conductive, as is skin, having skin to skin contact with another person allows you to pass the Earth’s energy to him or her, regardless of whether he or she has rubber shoes on.

    I started sleeping on a half sheet at the bottom of my bed 4 weeks ago. It is connected to a grounding rod my electrician installed for me. I was amazed!!!! For the past two years I have complained of an “internal live wire” within me, but most noticeably at night in bed. The internal “live wire” had progressively gotten so bad in the last two years I couldn’t sleep. I slept great grounded and was amazed, telling all my friends! Unfortunately, 5 nights ago something changed. The internal “live wire” was back and the half grounding sheet was causing a strong tingling on my skin. (I had tried a full sheet before and it was too much for me with tingling) Also, it caused some pain in my right hand. I want those good results back! Help please

    Donna…. I have tried the whole sheet for 6 hrs and wind up with full body aches that are incredibly stronger than flu symptoms. Total body, even my hair hurts when I touch it. At other times with the grounding pad I have had hip joiny pains etc. My daughter stopped using the sheet because of leg pains. My granddaughter gets coughing and almost bronchitis. What to do? I have over $600.00 invested. I really wanted the grounding as a health aid. I am 75 yrs old with heart problems, plaque and a-fib, plus a goiter and 7.5 PSA reading on the prostate. I am very disappointed. I really want it to help.

    Hi Chuck, It’s fairly common for some people to actually feel worse when they first start to ground and detoxify – especially if they are electro-sensitive. There’s Q&A above on this page that addresses these concerns: please see the answer to the following question for recommendations:

    Q: I was using a grounding mat and a grounding rod with a cord running outside, but started feeling very buzzed and often got flu-like symptoms afterwards. I am EMF sensitive – can you tell me why I feel this way when I ground?

    Best of health and happiness!

    I recently purchased grounding sandals and use them in my house. I assume I am grounded in the house with these sandals? I also sit outside with my bare feet in the grass, but it’s getting colder out now, so I think my time is limited with that (even though I’m really enjoying it – saying the Rosary and grounding, my two favorite stress relievers!) I also noted that I should only wear cotton socks or nylon stockings with my sandals when it’s too cold to wear them barefooted. Want to be sure I’m doing this correctly.

  8. HMDI Editors

    Grounding sandals allow you to ground when you are connected to the Earth. They allow the Earth’s energy to flow through the conductive rubber into your foot and body. They work when you are walking on sand, grass, dirt, cement, brick, and stone. Unless you are walking on unpainted concrete, they do not work when you are indoors because you are not actually connected to the Earth any longer. It is best to wear grounding sandals barefoot so that you have a good connection between your body and the sandal. Cotton socks and nylons are okay (especially if your feet sweat, which will enhance conductivity), but grounding barefoot is best.

    I am installing porcelain floor tile. That means the tile should be sealed and the grout should be sealed.

    Do we know if any particular tile sealants or grout sealants preserve the ability of at least the tile and possibly the grout lines to ground occupants who are barefoot? Is there a maximum allowable electrical resistance, measured in Ohms? I don’t mind curing samples and testing their electrical resistance, but it would also be nice to know if there is a maximum effective electrical resistance. I assume all mortars are sufficiently conductive as they are minerals.

    Thank you for any help or direction.

    I experienced Afib and had to have my heart put back into rhythm. I have been put on a new type of blood thinner, xeralto, for 1-2 months. I had read that grounding thins the blood so I have stopped grounding. However, I miss the great way I feel and sleep grounded. I’m also on low dose beta blocker. My question: with these new types of blood thinners is it safe to ground?

  17. HeartMD Editor

    on June 23, 2017 at 10:14 am

    Hi Marty,

    When taking a blood thinner you must exercise caution with grounding and remember that it does thin the blood. Before grounding you should consult with your doctor regarding how you will monitor your blood clotting time, because when taking Xarelto you generally do not have your blood drawn for this type of testing (those taking Coumadin regularly have blood drawn to test clotting time). Walking outside barefoot for a small period of time each day is your best bet because the effect should be more subtle.

    Will artificial grass laid on stone base prevent grounding

  19. HeartMD Editor

    on November 20, 2017 at 11:30 am

    Hi David,

    The artificial grass will likely block the transfer of the Earth’s subtle energy from the stone into your feet because it is made of plastic or other materials which are not conductive.

    Will walking barefoot on my concrete balcony work? I live on the 27th floor of a high rise and I am not sure if my balcony is grounded to the earth.

  21. HeartMD Editor

    on December 26, 2017 at 11:20 am

    Hi Maggie,

    It is hard to say, but I would guess that this would not be a great ground source and may not be connected to the ground at all. The only way it would be grounded would be if there is any metal framing of the building that is attached to the concrete and also reaches into the ground – not very likely. Concrete that is poured over the ground will be a good conductor of the Earth’s energy. Unfortunately in your situation, the concrete is just not connected to the Earth so it would not be grounded.

    Hi There,
    I take Paroxetine (Seroxat), will grounding interfere with its absorption, and could I potentially require less? Just wanted to say that although it is early days (I have been using a grounding pad in bed for 5 days) I have had insomnia since childhood, I am sure I have felt more relaxed at bed time and fall asleep much quicker! Think I am getting some detox symptions too though! May also be worse as I am so ‘electric , giving myself and others shocks regularly, as well as light bulb blowing… husband calls me the electric witch!

    Is grounding a possibility for someone living in Manhattan? It’s a concrete jungle (there is a huge maze of pipes and wires beneath buildings) and the only patches of grass have been pooped on by dogs for countless decades, which means going barefoot is a hazard.

  27. Rhonda

    on February 5, 2018 at 7:46 pm

    I wanted to know if the following meet grounding/earthing requirements:
    1. Three types of concrete: Concrete poured over gravel and wire mesh with the following types of concrete: 1. broom finish 2. stamped concrete 3. both broom finish and stamped concrete with sealed treatment to protect the concrete from the weather.
    2. Tile laid on concrete foundation inside the house. The tile is colored with a grey color that looks like white wood. Does this meet grounding/earthing requirements?

  28. HeartMD Editor

    on February 14, 2018 at 8:57 am

    Hi Oscar,
    It can be a challenge in the city. If the outlets where you live are grounded, you can use Earthing products in your home. If you prefer to ground by walking outside, you can use Earthing shoes. The company Pluggz has a great selection of men and women’s grounding footwear that you can see here. Not only are they attractive, they are specifically designed for full support and comfort.

  29. HeartMD Editor

    on February 14, 2018 at 9:04 am

    Hi Rhonda,
    You can ground by touching concrete that is in contact with the Earth as long as it isn’t sealed with anything. Tile may work but it depends on what it is made of and what rests underneath it.

  30. HeartMD Editor

    on February 14, 2018 at 9:06 am

    Hi Melanie, If you aren’t comfortable walking directly on the Earth, you can use Earthing shoes. The company Pluggz has a great selection of men and women’s ballet flats, wedges, loafers, flip flops and more. See the selection here. Not only are they attractive, they are bio-mechanically designed for complete support and lasting comfort.

    Hi Ness,

    We do know that Earthing can cause physiological changes that result in the need for medication changes. I have not heard of it affecting SSRIs but that doesn’t mean it couldn’t. I’d recommend starting slowly and carefully monitoring how you feel as well as discussing with your doctor and proceeding under their supervision.

  32. HeartMD Editor

    on February 14, 2018 at 9:35 am

    Hi Angela,
    Earthing/Grounding is no different than walking barefoot on the beach. It is ok to do if you have a pacemaker. However, we do always recommend discussing it with your doctor.

    on February 21, 2018 at 10:25 am

    Hi Andrew,

    You’ll reap the most benefit by grounding as much as possible, because when grounded we are at our natural electrical state. So, daily would be best, but whatever time you can fit in will be good enough.

    Hi there,
    We live in a city one block from the ocean on the top floor of a 1950’s, 7 storey, block: with views of sea. The apto block is of concrete blocks with, I imagine, pleanty of steel reinforcement inside.

    Our terrace is covered in terracota tiles over re-inforced concrete. Part of the inside of the apto si covered with floor tiles, the other with polished concrete. On ground level there is a square nearby – concrete! – but I could at least sit there and put my feet on the ground. Any good?

    I walk barefoot almost all the time up in my apartment and on the terrace – but is there any grounding to be had, do you think?



  39. HeartMD Editor

    on March 2, 2018 at 8:57 am

    Hi Susana,

    It’s hard to say…The only way that conductive building materials such as tile or concrete will ground you, is if they have some connection to the Earth.

    hi there, ordered my grounded sleeping mat, cant wait to get everyone i know going…..question, why are so many supposedly electrosensitive people feeling so sick and having to slow down?i get the detoxing thing totally and body circuits readjusting, im very sensitive to energy fields as well, but even if you are extremely sensitive to energies, you can lay on the beach all day (most of the time in the shade, lol, except maybe a half hour for your vitamin D) on just a thin cotton sheet or thin cotton beach towel with bare feet in sand and feel great, not feel sick or detox too quick? if youre on a full grounded sheet or very conductive grounded sleeping mat, connected to a grounded outlet, does the grounding rod of your home (im assuming thats how builders do it?) somehow pull more electrons to it, than if you were just laying on the Earth? Now Im nervous about how long to use my product at first, after all these comments….when i was looking forward to my first goodnights sleep in 20years (anxiety) by laying on it all night…..i detox one way or another every day and eat organic….i read about starting out slowly if you have issues with sensitivity or detox too fast and to me thats just common sense, but can you explain the difference between lying on the earth for hours and on the devices for these electrosensitive people, thats really bugging me, bc everyone keeps saying its no different than being on the earth ? thanks carrie

    If I ground a cement screed, will stone flags overlaid on the screed be grounded and grounding?
    The downstairs of my house has continuous stone flags laid over a continuous cement screed,
    I’m guessing the flags are not grounded because this screed is over a thick layer of EPS insulation over a continuous plastic damp proof membrane.
    But I could get an earthing wire into the screed where it is exposed at the top of the cellar steps, connected to a rod in the earth beneath the floor of the cellar. Would that make the stone flags grounded?

    There are so many EMFs within houshold appliances, and these travel through household wiring. Incluing the “earth” part of the wire. It has been proven, that the 3 wires within the one, for household ectrcity, transmit an EMF field into wires within the 3 wires strand.
    If you earth to the “house earth”, then you are plugging into these wires in your house. The house earth is dsigned so ALL the wirse in the house can “short” to earth. But with so many appliances within a house throwing out EMFs, i wanted to mak sure i only got electrons from one ground, wihch is not contaminated in any way. Which is not connected to any other wires in the house.

    I have ONE earth rod, which is just for my earthing wire. This is so there can be no “EMF” contamination” from other wirong from within the house. It works great! Asleep in 15 mins instead of 1.5 hours, otherwise.

    I just moved house, and i notice my other house, had stronger “grounding” than the new house, even though i still sleep well. 🙂

    Question: I have a double grounding sheet and only one plug is properly grounded.. Is one side plugged in enough for for that one side or do both Sides have to be plugged in have to work? Thank you for a quick reply, Suzy

    HI, I have a problem. I am 85 years old and am on Xaralto. I had 4 mini strokes 25 years ago, and they never found out why these occurred. So they put me on a blood thinner, and have been on it for many years. The strokes did stop.
    I have a large bed mat and enjoy it. I staeted getting Liver Sponts on my arms and figured it was because of the blood thinner.
    I have reduced my tables to 2 a week, and they seem to be disappearing. After a few week on the mat, I did visit my Dr., and she is aware that I have shortened my blood thinner. Had many test with her and also a blood test and all is good with the test.
    I have been oh a grounding mat now for about 2 months and feel wonderful. I am an active senior, play golf, bridge and lobe to go.
    I feel wonderful since I have been on the mat, but just wanted to hear any comments you may have on my situation. Thanks for any advice you can give.
    Diane V.

    Hello —
    During the colder months when there is snow on the ground, is it ok to put down a cotton towel to stand on with my earthing shoes? I want to prevent damage to the delicate leather of the shoe and wonder if a cotton towel would block or still allow the currents to pass through. Thank you!

    Are there any cautions with grounding or earthing if you have a pacemaker?

    My apartment was built in 1958 so electric outlets not grounded. I have a grounding rod outside my bedroom window with the wire coming through the window to snap onto my grounding Matt. The wire is too long & gets tangled. Also, sometimes I have to close & lock my window when I go out, so I have to push the wire back up inside the window sill so I can close the window without damaging the wire. To solve this problem I wrapped my long wire around a small empty plastic water bottle so it doesn’t get all tangled& I can easily get it all back up inside the window when I need to. Is the plastic bottle blocking my grounding or am I still grounded.

    I have a grounding rod outside my bedroom window with the wire coming in to snap on to my grounding Matt. The wire is long so I wrapped the excess wire around a small empty plastic water bottle in order to make the tangled wire more manageable for when I need to shove it back through the window so I can close & lock the window when I go out. Is the plastic water bottle blocking my grounding or am I still grounded?

    What about the chemicals you more than likely are standing on that are sprayed on most grasses if you live in an suburban or urban area? Can’t your skin absorb those chemicals into your body while you are grounding.

    Sure, you could absorb them if they were recently sprayed (and it hasn’t rained since). Probably best in areas likely to have been sprayed to wear a pair of thin cotton socks; the Earth’s energy won’t be as readily absorbed into the feet, but you’ll be better protected against synthetic pesticide/insecticide exposure.

    If I were to sit in the branches of a tree (especially barefoot), would the connection through the tree still allow my body to ground?

    I used an earthing mat (first time) for 30 minutes after dinner and felt tingling in my feet and later in my hands. Then I woke up in the middle of the night, and my heart was racing along with continued tingling. It was very unpleasant – even scary! It took a couple hours of walking around and breathing deeply and praying before my heart rate came down, and I was able to go back to bed. The following day, I had a headache and after two days, still a slight headache. To me, it seems like I was on the receiving end of unwanted electricity. There is a lot of growing information about the danger of actually drawing “dirty electricity,” when using mats and sheets indoors. Disappointed but don’t feel comfortable trying that again. Has anyone else had a similar experience?

    Karen, we consulted with Marty Zucker on your question. He is co-author of my book Earthing: the greatest discovery ever? and has been closely following the research with scientists in the field. Here are a couple of pointers we got from him:
    1. Those who do have reactions to earthing equipment may be electro-sensitive/EMF sensitive and/or have a background of stress that has led to some adrenal weakness. They may also be having a detox reaction. As you did, we recommend that they stop. You may try to reintroduce grounding more naturally—such as walking barefoot on grass, sand, concrete; making contact with trees— beginning with short time periods, like 10 minutes. See how it goes. Natural grounding may be all you care to do.
    2. If you, after doing well outside, do decide to try a mat again, check the outlet you will be using to be sure it is properly grounded. Earthing Institute kits come with a device to check. If you are in a house with a yard, you may opt to try a grounding rod that is inserted into your yard instead of using a plug The rod comes in a kit with a long wire that can come in through a window. For more earthig basics and info on the rod:

    This is what Marty Zucker has learned after years working with scientists and researchers:

    Hope this helps you make your own decision as to how to proceed.

    Hi Sandi,

    Can you please explain why those people who appear to get negative reactions from using the earthing products, can tolerate being on the natural earth? Since the earthing products are meant to simulate being on the natural earth, then why do some people get those negative reactions using the products but not on the actual earth?

    (this is basically a simplified version on the question by “dr carrie s” a couple posts ago which was not answered)

    Thank you Grant for reaching out. We reached out to our colleagues at the Earthing Institute and this is what they had to say.
    “In the beginning, some people may feel flu-like symptoms that include malaise, achiness, headache, a foggy mind, tiredness. Muscle cramps and disturbed sleep might occur. Our observations suggest that a healing, normalization process is underway because of Earthing’s ability to improve blood flow and oxygenation of the tissues as well as restore a natural electrical state in the body. Systemically, more efficient cell repair and function takes place, promoting a clear-out of wastes and toxins. Such detoxification could result in the symptoms just mentioned. Nerve fibers may function better, resulting in unaccustomed sensations. Earthing has given the body additional resources to clean up and try to return to normal. Energy is expended in this process, so people sometimes feel initial fatigue before feeling increased energy. These responses vary from person-to-person, and when they occur, generally ease off within a week or two.”
    This is a great resource to help answer more questions on grounding.

    Could copper compression docks work for earthing or grounding,?

    Can I ground with any part of my body, or does it need to be my feet? For example, if I touch soil with my hands while gardening, does that allow for grounding? Thank you!

    How about rubbing a magnet on the soles of your feet for grounding?

    Can my dog experience grounding on artificial grass?
