“Grounding” products all promise the same physical thing: to connect your body electrically to the Earth. That part is measurable, and most of them do it. Whether it changes how you sleep or how stressed you feel is a separate question the evidence has not settled. So this list ranks products by the one thing you can check at home — whether you can prove they grounded you — and ends with a free experiment for the other question.
We name no brands, because we have tested none. Every pick is a category, what to look for in it, and a test to run with the meter. Facts about how these products are built were verified 13 September 2026. One pick is ours, and it says so.
Read this before you buy anything
The isolation is real. Synthetic soles on synthetic floors electrically insulate you from the Earth, and a body in a wired house floats at a small AC voltage from the wiring around it; walking on carpet can add static charge measured in thousands of volts. That sounds enormous, but it is a high voltage with almost no stored charge, the kind that matters to sensitive electronics. Touching anything grounded takes it to near zero.
The evidence for what that does to you is thin. The published earthing studies are small, rarely blinded, and mostly from people who already sell the idea. They also share one large confounder: being barefoot on the Earth almost always means being outside, moving, in daylight and away from a screen, and that alone lowers stress in better studies. Nobody has yet separated the electrons from the grass. The experiment at the bottom of this page is designed to.
So the only product that is essential is the meter. A grounding sheet plugged into an outlet with no ground, a mat used through socks, or shoes worn on a wood deck ground nobody, and you would never know from feel. The meter tells you in ten seconds.

Body-voltage meter (earthing test kit)
A meter that reads the AC voltage between your body and the ground pin of an outlet, in millivolts. It is the only product on this page that can tell you whether any of the others did anything: a body isolated from the Earth in a wired house typically reads volts, a grounded one reads millivolts. Everything below is judged by this number.
What to look for
- Reads AC millivolts (a general multimeter with an AC mV range plus a ground cord does the same job)
- Ships with a ground cord that plugs into the round ground pin only, never the flat blades
- An inline resistor in the cord (commonly 100 kΩ), which limits current if a fault ever puts mains on the ground
Verify it. Stand in shoes on carpet holding the probe and note the reading. Then touch a grounded metal object or a plugged-in grounding cord with your other hand. The number should collapse by a factor of ten or more. If it does not, your outlet is not grounded — see the next pick.
Best for. Anyone about to spend money on grounding anything. Buy this first, or borrow one.

Outlet receptacle tester
A three-light plug that reports whether an outlet is wired correctly and, crucially, whether its ground pin is actually connected to anything. Every indoor grounding product on this page relies on that pin. Open grounds are common in older houses and in rooms that were rewired by someone in a hurry.
What to look for
- Three-light type with an explicit "open ground" pattern on the label
- A GFCI test button is a bonus, not a requirement
Verify it. Plug it in. Two amber lights and no red is a correct ground on most testers; read the legend printed on the tester itself. Test every outlet you intend to plug a grounding cord into, not just one.
Best for. Everyone using a sheet, mat or cord indoors. Without this, a grounding product may be plugged into nothing.

Grounding sheet (fitted or half-sheet)
A bedsheet woven with conductive thread, usually silver, with a snap and a cord to an outlet ground. Bare skin on the sheet puts your body at ground potential while you sleep. It is the product most people mean by "earthing", and the one where a blinded trial is possible at home: the sheet feels identical plugged in and unplugged.
What to look for
- Conductive thread stated as silver or carbon, with a percentage; a printed grey pattern is not conductive
- Cord with an inline resistor, and a snap rather than an alligator clip
- Care instructions that forbid fabric softener and bleach: softener coats the fibres and kills conductivity, which is the most common way these stop working
Verify it. Lie on the sheet with bare skin touching it and read your body voltage with the cord plugged in, then unplugged. Repeat monthly; a sheet that has been washed with softener will read the same either way, and it is then just a sheet.
Best for. The optional night arm of the experiment, and anyone who wants the one grounding test that can be blinded.

Grounding mat
A carbon-loaded rubber or leatherette mat with a snap cord to an outlet ground. Bare feet or wrists on the mat ground you while you sit. Through socks or trouser fabric it does nothing, which is the most common reason people report no change: they never touched it.
What to look for
- Conductive surface stated (carbon-infused rubber, conductive leatherette); a plain rubber mat is an insulator
- Large enough for both bare feet, or a wrist strap for desk use
- Cord with an inline resistor
Verify it. Bare feet on the mat, meter in hand, cord plugged in: millivolts. Lift one foot onto a shoe: the reading should stay low as long as the other foot is on the mat. Put socks on: the reading should climb back up. If it stays low through socks, the meter is reading something other than the mat.
Best for. Indoor controls, and anyone who spends their day at a desk and wants a grounded baseline without going outside.

Grounding shoes (conductive-sole footwear)
Shoes with a conductive path from the insole to the ground through the sole, usually a copper rivet or a carbon plug. They only ground you on ground that is itself conductive: soil, grass, damp concrete, sand near water. Asphalt, wood decks, vinyl and dry concrete are insulators, and on those the shoes are ordinary shoes.
What to look for
- An explicit conductive plug or rivet through the sole, visible from underneath
- A conductive insole or lining so the plug reaches your foot through a sock
- Leather or natural-fibre uppers matter less than the sole path; the sole is the whole product
Verify it. Stand on damp soil or grass in the shoes, meter cord to a verified outdoor ground or a long lead back inside, and read. Then stand on the same grass barefoot. The two readings should be close. Then stand on a wood deck in the shoes: the reading should climb, proving the shoes only conduct through conductive ground.
Best for. The "shoes grounded" arm of the experiment, and anyone who wants the electrical condition of bare feet with their feet covered.

Closed-cell foam or rubber mat
A plain exercise mat, thick enough to stand on. It is the product that makes a real test possible: barefoot on the mat on the grass gives you everything about being barefoot outdoors, minus the electrical connection. Without it, you cannot tell the electrons from the grass.
What to look for
- Closed-cell foam or solid rubber, not a woven or open mesh mat that wicks moisture
- Big enough to stand or sit on with nothing touching the ground beside it
Verify it. Barefoot on the mat on grass: the meter should read high, like shoes. Step off onto the grass: it should drop. That contrast is the whole experiment in ten seconds.
Best for. The "barefoot insulated" arm. The cheapest and most important control on this page.

Bare feet on soil, grass or damp sand
The reference every product above is measured against, and it costs nothing. Ten minutes barefoot on the lawn grounds you as completely as any sheet. It also puts you outside, moving, in daylight and away from a screen, which is exactly why it is impossible to say from feeling alone whether the electrons did anything.
What to look for
- Soil, grass, damp sand or damp unsealed concrete. Not a deck, not asphalt, not a sealed patio.
Verify it. Meter in hand, long ground lead: near-zero on grass, climbing the moment you step onto a deck.
Best for. Everyone, as the free baseline. Buy nothing until you have tried this and measured it.

The four-arm grounding self-experiment
Ours, and free. A 24-day randomized crossover: barefoot grounded, barefoot insulated, shoes grounded, shoes insulated, with the place, the time of day and the activity held constant. You measure body voltage first to prove the arms differ, pre-register your prediction, then track resting heart rate, HRV, sleep and a daily stress rating. Your result, confirmed or refuted, joins an open record with everyone else's.
What to look for
- Everything on this page except the sheet is used in it; the sheet is an optional night arm
- Not a treatment for anxiety and not medical advice, and it says so on the page
Verify it. The experiment is the verification. Refutations are as welcome as confirmations, and count for the same.
Best for. Anyone who has felt better barefoot on grass and wants to know whether it was the electrons or the grass.
