Product details
The GroundingFlow™ Sleeping Earthing Mat is made from a premium conductive, carbon-infused fabric that keeps a continuous electrical connection between your body and the Earth's natural charge — every night, while you sleep.
How it works: plug the included grounding cord into the ground port of any standard wall outlet. Through bare-skin contact, the mat connects you to the Earth's free electrons. No electricity flows through the mat — it's the same bioelectrical connection you get walking barefoot on grass or soil, now available indoors, all night.
- Premium conductive fabric: carbon-infused for consistent, uninterrupted contact across the whole surface — not just at one point.
- Research-backed: grounding has been studied in 20+ published papers, including the Journal of Alternative and Complementary Medicine and the Journal of Inflammation Research.
- Built to last: engineered for nightly use, with materials that keep full conductivity for years with proper care.
- Universal compatibility: works with any standard grounded outlet — choose your US, UK, EU or AU plug above.
- American-owned: designed and quality-tested in Florida, USA.
What's in the package
- 1× GroundingFlow™ Sleeping Earthing Mat

Care & dimensions
The mat is naturally resistant to odor-causing bacteria and needs very little maintenance. When it does need cleaning:
- Wipe gently with a soft, damp cloth and a mild soap solution
- Air dry in a well-ventilated area — don't tumble dry
- Don't machine wash — it can damage the conductive fabric
- Avoid bleach, harsh chemicals and oils — they degrade conductivity over time

What is grounding? The connection modern life quietly took away.
The Earth's surface holds a mild negative charge — a vast reservoir of free electrons, constantly replenished by lightning and solar radiation. For hundreds of thousands of years, humans slept in direct contact with it. Rubber soles, raised beds and insulated floors severed that connection almost overnight.
Grounding — also called earthing — simply restores it. One cord to the ground port of a standard outlet, which is wired to a copper rod in the earth beneath your home, and your body rests at the Earth's potential all night.
Grounded in two minutes. No tools. No electrician.
Three steps tonight. Every night after that, it just works.
-
Step 01
Cover your mattress
Lay the mat edge to edge like a fitted sheet and hook the corner straps. Bare-skin contact works best.
-
Step 02
Plug into the ground port
The cord snaps onto the mat and uses only your outlet's ground — the port that's wired to the earth. No electricity flows.
-
Step 03
Sleep grounded
That's the whole protocol. Eight hours of Earth contact a night, with zero effort.
Not sure your outlet is grounded? The included tester confirms it in seconds — green light means go.
The Earth has a charge. You're meant to be connected to it.
Touch the Earth with bare skin — through grass, soil or a grounding mat — and free electrons flow into your body. Modern shoes, beds and floors keep you insulated for weeks at a time, so instead you soak up a charge from the wiring around your bed. The mat recreates the Earth connection indoors, every night.
Illustrative reading based on the 58× average drop measured in a 50-person study. Your numbers depend on the wiring around your bed — don't take our word for it: measure it with a multimeter.
-
01
58× lower body voltage
Grounding cut the AC charge your body picks up from household wiring, Wi-Fi and appliances by 58× on average — measurable in seconds with a standard multimeter.
-
02
Free electron transfer
Research suggests grounding transfers free electrons from the Earth into your body, where they may act as natural antioxidants at the cellular level — no pills involved.
-
03
20+ published studies
Papers in the Journal of Alternative and Complementary Medicine, the Journal of Inflammation Research and other journals have measured grounding's effects on the body.
Brown R. Effects of grounding on body voltage and current in the presence of electromagnetic fields. J Altern Complement Med. 2016;22(9):757–759. Average 58× reduction across 50 participants.
Inflammation, visualized. Ungrounded vs. grounded.
What the research describes, made visible: hotspots of inflammation and accumulated charge calming once the body has a path to the Earth.
Grounded sleepers in an 8-week pilot reported less pain — customers feel it first in their knees and hips on the morning stairs.
The leading theory: the Earth's electrons act as natural antioxidants, calming the free radicals that keep inflammation simmering.

One mat. Seven systems it reaches.
Grounding acts on several biological systems at once. Select one to see the mechanism and the research behind it.
Sleep architecture & circadian rhythm
Grounding doesn't just make you feel more rested — it appears to act on the hormone that runs your sleep–wake cycle. In an 8-week study of grounded sleep, night-time cortisol dropped and its 24-hour rhythm moved back toward its natural arc: high in the morning, low at night.
- Lower night-time cortisol after 8 weeks of grounded sleep
- The 24-hour cortisol rhythm moved back toward normal
- Nearly all participants reported better sleep and less stress
- Works during the eight hours you're already in bed
Inflammation & electron transfer
Chronic, low-grade inflammation sits underneath much of what people feel as pain, stiffness and fatigue. The leading hypothesis in grounding research: the Earth's free electrons act as natural antioxidants, neutralizing the positively charged free radicals that keep inflammation going.
- Free electrons proposed to act as natural antioxidants
- Shifts in white blood cells and inflammatory markers reported in studies
- Reviewed in the Journal of Inflammation Research
- No drugs, no pills — the mechanism is bioelectrical
Nervous system & stress
Most people spend their days stuck in sympathetic overdrive — the fight-or-flight state — driven by stress, poor sleep and constant stimulation. Grounding research points toward the other side of the nervous system: rest, digest and repair.
- Better mood vs. sham grounding in a double-blind pilot
- Research points to a shift toward rest-and-repair tone
- Lower night-time cortisol, the stress hormone, in grounded sleepers
- A calmer wind-down with zero extra effort
Pain relief & faster recovery
Pain is very often downstream of inflammation, which is why grounding research measures both. In a randomized, sham-controlled trial, a key marker of muscle damage rose after hard exercise in the sham group — but not in the grounded group.
- Muscle-damage marker (CK) held steady in grounded men vs. sham
- Grounded sleepers reported less pain in an 8-week pilot
- Works on the inflammatory environment, not just the pain signal
- Stacks with your existing recovery tools — cold, heat and red light
Circulation & blood flow
One of the most interesting findings in grounding research involves zeta potential — the electrical charge on the surface of your red blood cells that keeps them from clumping together. After two hours of grounding, zeta potential rose by an average factor of 2.7 and red-cell clumping dropped.
- Red blood cell zeta potential up 2.7× on average
- Less red-cell clumping, so cells flow more freely
- Researchers infer lower blood viscosity
- Supports healthy circulation while you sleep
Cortisol & hormonal rhythm
Cortisol is supposed to peak in the morning and fall at night. When that rhythm flips — high at night, flat in the morning — you lie awake wired and wake up exhausted. It's one of the most common patterns in modern life, and grounding is one of the few non-pharmaceutical tools studied for it.
- Night-time cortisol reduced in grounded sleepers
- The 24-hour rhythm trended back toward normal over 8 weeks
- Changes were most apparent in women in the original study
- No prescription — the effect is bioelectrical
EMF & body voltage
Every electrical device in your home — the wiring in your walls, your Wi-Fi router, your lamp, your phone — induces a small AC voltage on your body through capacitive coupling. You can't feel it, but a multimeter can see it. Grounding gives that charge a path out, almost instantly.
- Body voltage cut by 58× on average in a 50-person study
- Measurable in seconds with a standard multimeter
- Discharges the AC charge induced by household fields while you sleep
- Passive and drug-free — nothing to remember, nothing to charge
“What is really happening with grounding or earthing is that you're protecting your body from collateral damage — damage that was not intended to take place but does take place because we have disconnected ourselves from the earth by putting rubber and plastic on the bottom of our shoes.”
- Improves sleep quality
- Helps reduce inflammation
- Supports healthy circulation
- Restores body voltage balance
Quoted on grounding research in general. Dr. Oschman's words are not an endorsement of GroundingFlow.
Small studies. A consistent signal.
Grounding has been studied for sleep, cortisol, body voltage, mood, recovery and circulation. The studies are small — we'll never pretend otherwise — but they keep pointing the same way. Here's exactly what they found.
Promising, not settled. Several of these researchers have worked with grounding companies, so we link every paper — and give you 90 nights to judge for yourself.

Sleep & cortisol
Sleeping grounded for 8 weeks lowered night-time cortisol and moved its 24-hour rhythm toward normal. Nearly all participants reported better sleep and less pain and stress.

What happens over 60 nights.
Grounding works cumulatively. Here's what our customers most often report at each stage — everyone is different, which is why you get 90 nights.
-
Night 1–3
Deeper sleep & a calmer nervous system
Many people notice a heavier, more restful sleep almost immediately. Body voltage drops within seconds of contact — you can measure it — and the shift toward rest-and-repair begins.
-
Week 1–2
Waking refreshed, energy rising
Fewer night-time wake-ups and less morning grogginess are the most common early reports. As your cortisol rhythm settles — higher in the morning, lower at night — daytime energy tends to steady.
-
Week 2–4
Less pain, easier mornings
Customers most often mention less joint stiffness, less muscle soreness and less tension at this stage — along with feeling calmer and more even.
-
Month 2+
Your new baseline
Sleeping grounded stops feeling like a product and becomes part of how you sleep. Customers describe steadier energy, easier mornings and fewer aches as their new normal.

Frequently asked questions.
Can't find your answer? Email info@groundingflow.com.
Contact usDoes grounding actually work? Is there real science behind it?
Grounding has been studied in more than 20 published papers, in journals including the Journal of Alternative and Complementary Medicine and the Journal of Inflammation Research. Researchers have measured lower night-time cortisol, better sleep and mood, a smaller rise in a muscle-damage marker after hard exercise, and a 58× average drop in body voltage.
Most of these studies are small, so we link every one. Then you test it on yourself for 90 nights.
Will electricity flow through the mat? Is it safe?
No electricity flows through the mat. The cord connects only to the ground port of your outlet — the same safety ground every appliance in your home relies on, wired to a copper rod in the earth beneath your house. It's a passive connection: the electrical equivalent of standing barefoot on grass. As with anything connected to your home's wiring, unplug it during electrical storms.
How quickly will I notice results?
Many people notice deeper sleep within the first few nights. Customers most often report less stiffness and soreness over 2–4 weeks of nightly use, with steadier energy as their sleep improves. Grounding is cumulative — the more consistently you sleep on it, the more you tend to notice. Everyone is different, which is why you get 90 nights.
How do I know if my outlet is grounded?
Every mat comes with a conductivity tester. Plug it in before your first night — a green light confirms your outlet is grounded and your mat is connected. Most modern three-prong outlets in the US, UK, EU and Australia are grounded by default.
Can I use it with a pacemaker or other medical device?
Talk to your physician before use if you have a pacemaker, an implanted defibrillator or another implanted device, or if you take blood-thinning medication. Grounding has been studied for its effects on the blood, so your doctor should weigh in first.
What sizes are available?
Single — 70 × 180 cm (28 × 71 in) for one sleeper, and Double / Queen / King — 140 × 180 cm (55 × 71 in) for two. Both include the grounding cord and the conductivity tester.
How do I care for the mat?
Wipe it with a soft, damp cloth and a little mild soap when needed, then let it air dry. Don't machine wash or tumble dry, and avoid bleach, harsh chemicals and oils — they wear down the conductive fabric. Cared for this way, your mat keeps its conductivity for years of nightly use.
What is your return policy?
You're covered by our 90-day money-back guarantee. If you don't sleep deeper, feel better or notice a difference, contact us for a full refund. No forms, no back-and-forth.
How soon will my order arrive?
Orders are processed within 1–2 business days from our Florida, USA facility, and you'll get a tracking link by email. Delivery usually takes 8–10 business days to the US, Canada, the UK and Europe, and 5–10 business days to Oceania. US shipping is free, and international shipping is free on orders over $100.
