Grounding and Wound Healing: The 2015 Review

Short answer: no, there is no real evidence that grounding sheets heal wounds faster. The single paper
people point to for this claim is a 2015 narrative review that proposes a mechanism, not a clinical trial that
measured actual wounds closing. If you’re dealing with a wound, a grounding sheet is, at best, a low-risk comfort
add-on next to whatever your doctor already has you doing, not a treatment.

What does the 2015 review actually say?

The paper people cite is Oschman, Chevalier and Brown (2015), published in the Journal of Inflammation Research
under the title “The effects of grounding (earthing) on inflammation, the immune response, wound healing.” That
title alone is why it gets forwarded around wound-care forums. But read past the title and it’s a narrative
review, meaning the authors gathered existing research and physiology and built an argument from it. It isn’t a
study where researchers grounded a group of people with actual wounds and measured healing time against a control
group.

The argument the paper makes is about free radicals. Grounding, the authors propose, may supply the body with a
steady source of electrons from the earth, and those electrons could act as antioxidants, neutralizing the
reactive oxygen species that show up during inflammation. Inflammation is part of normal wound repair, so in
theory, less oxidative stress could mean a smoother healing process. That’s the chain of reasoning. Every link in
it is plausible on paper. None of it has been confirmed with wounded patients.

Is there any actual data behind the wound claim?

Not in the way you’d want for a health decision. The review leans on smaller pilot studies from the same
research circle, including work from Chevalier and Sokal and Sokal (2011), which looked at things like blood
markers, calcium and phosphorus balance, and immune activity in grounded versus ungrounded participants. Those
studies are worth knowing about, but they weren’t measuring wound closure either, and they share the limitations
of most earthing research: small groups, no blinding, and researchers who are also connected to grounding
products.

Separately, Brown, Chevalier and Hill ran small pilots on delayed-onset muscle soreness after exercise, which is
a different kind of tissue repair than an open wound but gets lumped into the same “grounding helps healing”
talking point online. If you’re specifically interested in exercise recovery rather than wound care, we cover that
distinction in our guide to Grounding Sheets for Athletes: Recovery, Claims and Reality. For wounds specifically, there is no dedicated
clinical trial in the anchor literature, just the theoretical case built in the 2015 review.

How would grounding even affect healing, in theory?

The mechanism, if it’s real, runs through inflammation and the immune response rather than the skin directly.
We break down the inflammation half of this argument in more depth in Grounding and Inflammation: What the Research Actually Measures, and the
immune-system claims specifically in Grounding and the Immune System: The Claims. Both pages draw from the same 2015
review, because the authors packaged inflammation, immunity and wound healing into one theoretical framework
rather than three separate bodies of evidence.

That’s worth sitting with for a second. When one review paper is the source for three or four different health
claims across the internet, it can look like a mountain of evidence when it’s really one hypothesis, restated. I
say this as someone who wants grounding to work. It’s a fair critique, and skeptics who point it out aren’t wrong.

What does this mean if you have a wound or slow-healing skin?

Talk to your doctor first, especially if the wound is slow to close, keeps reopening, or you have a condition
like diabetes that’s known to affect circulation and healing. A grounding sheet is not a wound dressing, an
antibiotic, or a substitute for actual wound care. Nothing in the research anchors this site relies on supports
using it that way, and no honest reviewer would tell you otherwise.

Where a grounding sheet might reasonably fit is as a low-risk addition to your sleep setup while you’re
recovering from something unrelated, since the best-supported outcome in this research area is sleep quality, not
tissue repair. If better rest is part of what you’re after during recovery, our guide to
Grounding Sheets for Sleep: Can Earthing Improve Your Nights? covers what that evidence actually shows and where it falls short.

Should you even bother trying grounding for this?

If you’re healthy and just curious, there’s little downside to sleeping grounded, provided your outlet is
properly wired. If you’re managing an actual wound, don’t let a sheet distract you from real treatment, and don’t
expect it to speed anything up. If you decide to try grounding anyway, for sleep or general comfort while you
recover, look for stainless-steel fiber construction over silver thread. Silver conducts well when new but
oxidizes with repeated washing, so it loses effectiveness faster. That durability gap is the main reason our
tested pick is the Premium Grounding Sheet.
