What is Grounding

The short version

The Earth's surface carries a natural negative charge. When you're in direct contact with it — barefoot on grass, sand or soil — your body and the ground settle at the same electrical potential. Grounding, also called earthing, is simply the practice of restoring that contact. A grounding sheet does it indoors, using the ground pin in an ordinary wall outlet, which runs to a rod driven into the soil outside your house.

Nothing about it is complicated. You're connecting to the same charge you'd get standing barefoot in the garden, without having to stand in the garden.

The Earth as an electrical reference

The planet's surface charge is continually renewed. Solar radiation and lightning move electrons through the atmosphere and back into the ground, keeping the Earth's surface negatively charged. This part isn't controversial — it's ordinary atmospheric physics, and it's the same principle behind the electrical grounding already wired into your home.

The modern disconnect

For most of human history people were in regular contact with the ground, barefoot or in leather that conducted. Modern life removed that. Rubber soles, insulated floors and raised beds mean many of us go weeks without touching the earth directly. A grounding sheet gives that contact back at the one time of day you're lying still for hours.

What the research shows

Grounding is not folklore with no paper trail. It has been studied in peer-reviewed journals since the early 2000s. Below is every study we rely on, and what each one actually did. We would rather you read this than take our word for anything.

The strongest evidence

A double-blind randomized controlled trial. Sixteen massage therapists were grounded for six weeks using cords that were inactive — sham cords — for part of the period, with neither the participants nor the researchers knowing which was which until the data was in. Pain scores fell from 8.2 to 5.8. Physical function and energy rose; fatigue and depressed mood fell. A month after the study ended, physical function was still improved and fatigue still reduced. (Chevalier, Patel, Weiss, Chopra & Mills, Explore, 2019.)

This is the design that matters. Blinding and a sham control are what separate a real effect from expectation, and this trial had both.

The rest of the literature

Vagal tone in preterm infants. Twenty-six babies in intensive care were grounded; skin voltage fell by roughly 95% and vagal tone, a marker of nervous-system regulation, rose by about 67%, returning to baseline when grounding stopped. (Passi, Doheny, Gordin, Hinssen & Palmer, Neonatology, 2017.)
Cortisol and sleep. Twelve people slept grounded while cortisol was measured and sleep, pain and stress were self-reported; cortisol rhythms shifted toward a normal pattern. (Ghaly & Teplitz, Journal of Alternative and Complementary Medicine, 2004.)
Facial blood flow. A randomized, placebo-controlled study of 40 participants reported improved regulation of facial blood flow. (Chevalier, Journal of Cosmetics, Dermatological Sciences and Applications, 2014.)
Blood viscosity. Ten subjects showed reduced blood viscosity and less red-cell clumping after two hours of grounding. (Chevalier, Sinatra, Oschman & Delany, Journal of Alternative and Complementary Medicine, 2013.)
Inflammation and blood flow. A randomized, double-blind pilot study found changes after one hour of contact with the earth's surface. (Chevalier, Melvin & Barsotti, Health, 2015.)
Muscle soreness and recovery. Pilot work on delayed-onset muscle soreness (Brown, Chevalier & Hill, Journal of Alternative and Complementary Medicine, 2010) and on muscle damage after eccentric contractions (Open Access Journal of Sports Medicine, 2015), plus recovery after intensive eccentric loading (Müller et al., Frontiers in Physiology, 2019).
Blood pressure. A case-history series of ten hypertensive patients. (Elkin & Winter, Alternative Therapies in Health and Medicine, 2018.)

What this does and does not prove

It proves the effect is worth taking seriously, and that people who dismiss grounding as nothing have usually not read the literature.

It does not prove grounding will do anything for you specifically. Most of these studies are small, ten to forty people, and several are pilots rather than full trials. And the single most quoted paper on grounding and inflammation (Oschman, Chevalier & Brown, Journal of Inflammation Research, 2015) is a hypothesis paper rather than new research, whose authors disclose that they are contractors for, and shareholders in, a company that sponsors earthing research. You will find it cited across the internet as though it were a clinical trial. It is not one, and we will not cite it that way.

So: a real, peer-reviewed body of work, with one properly blinded trial at the top of it and a set of small studies underneath. Promising, not settled. That is the honest position and it is the one we take.

Grounding is not a treatment for any medical condition. These statements have not been evaluated by the Food and Drug Administration, and our products are not intended to diagnose, treat, cure or prevent any disease.

What people report

People who sleep grounded frequently report falling asleep more easily, waking less through the night, and feeling more settled. Some notice a difference in the first week. Others never do.

What we can tell you for certain

What's in the sheet, how much pure silver is woven through it, where it's made, and how to care for it. Those are facts we control, and they're on every product page. The rest is yours to judge.
