Is It Safe to Use a Grounding Sheet With a Pacemaker?
Dr. Sarah MitchellIf you have a pacemaker or implantable cardioverter-defibrillator (ICD), consult your cardiologist before using a grounding sheet. Grounding involves a passive electrical connection to the earth — not active electricity — but the interaction between grounding and implanted cardiac devices is not well studied.
This article explains honestly what we know, what we don't know, and what questions to ask your doctor.
How Does a Grounding Sheet Work Electrically?
A grounding sheet connects your body to the earth's natural electrical field through the earth pin of your wall outlet. It's important to understand what this does and does not involve:
What Does the Research Say About Grounding and Pacemakers?
There is currently no published clinical research specifically examining the interaction between grounding (earthing) and pacemakers or ICDs. This is an important gap in the literature, and it means no one — including grounding product manufacturers — can definitively state that grounding is safe or unsafe for people with these devices.
What the general grounding research shows is that earthing the body affects measurable physiological markers. According to Chevalier et al. (2012), grounding during sleep reduces night-time cortisol and shifts autonomic nervous system activity. According to Oschman et al. (2015), grounding influences blood viscosity, red blood cell surface charge, and inflammatory response. DOI: 10.1089/acm.2011.0820 and DOI: 10.7863/jum.2015.34.1.1
These physiological changes — while generally considered beneficial for healthy individuals — mean that grounding is not "doing nothing." It has measurable effects on the body, which is exactly why medical clearance is appropriate for anyone with an implanted device that monitors or controls cardiac rhythm.
Why Is Caution Warranted?
Pacemakers and ICDs are sophisticated electronic devices that sense the heart's electrical signals and respond accordingly. They are designed to function within the body's normal electrical environment. Any external factor that changes the body's electrical state — even subtly — has the theoretical potential to be detected by these devices.
To be clear: we are not aware of any reported adverse events involving grounding sheets and pacemakers. But the absence of reported problems is not the same as proof of safety. The interaction simply hasn't been studied.
This is the same reason manufacturers of other passive wellness devices (such as TENS units, magnetic therapy products, and bioelectrical impedance scales) recommend medical consultation for pacemaker and ICD users.
What Should I Ask My Cardiologist?
If you're considering a grounding sheet and have a pacemaker or ICD, bring these points to your cardiologist:
Is Grounding the Same as an Electric Blanket?
No. This is a common misconception. Electric blankets generate heat by running electrical current through heating elements. They produce electromagnetic fields and consume mains electricity. Pacemaker and ICD manufacturers universally recommend avoiding electric blankets or using them with caution.
A grounding sheet does none of these things. It has no heating element, consumes no electricity, and generates no electromagnetic field. The cord connects only to the earth pin — a passive ground connection.
That said, the lack of similarity to an electric blanket does not automatically make grounding safe for pacemaker users. The prudent approach is still to consult your cardiologist, because the specific interaction has not been studied.
What About Walking Barefoot Outdoors?
Walking barefoot on grass, soil, or sand is electrically equivalent to using a grounding sheet. Both create a conductive pathway between your body and the earth's surface charge. If your cardiologist is comfortable with you walking barefoot outdoors, the grounding sheet is replicating the same electrical connection.
This comparison may help your cardiologist understand the nature of the product when you discuss it with them.
Our Position
We recommend that anyone with a pacemaker, ICD, or other implanted cardiac device consult their cardiologist before using a grounding sheet. We cannot and do not make safety claims for this population because the research simply doesn't exist yet.
We believe in being honest about what we know and what we don't. Grounding has measurable physiological effects — that's well established in the research. Whether those effects interact with implanted cardiac devices is an open question that only your medical team can answer for your specific situation.
Frequently Asked Questions
Is it safe to use a grounding sheet with a pacemaker?
There is no published research specifically studying grounding sheets with pacemakers or ICDs. Grounding involves a passive electrical connection to the earth (no active electricity), but because it has measurable physiological effects, anyone with an implanted cardiac device should consult their cardiologist before use.
Does a grounding sheet use electricity?
No. A grounding sheet connects to the earth pin of your wall outlet only — not to live or neutral pins. No mains electricity flows through the sheet. The cord includes a built-in 100k-ohm resistor as an additional safety measure. It is not comparable to an electric blanket or any powered device.
What should I tell my doctor about grounding sheets?
Explain that a grounding sheet creates a passive electrical connection between the body and the earth via the earth pin of a wall outlet. No active current is generated. A resistor is built into the cord. It is electrically equivalent to walking barefoot on damp ground. Key studies for reference: Chevalier et al. (2012) and Oschman et al. (2015).
