Good to Know
The sheet connects to the ground port of your outlet. No electricity flows through it.
Wait one hour after lotion or body oil before you lie on the sheet. Oils coat the silver and weaken the contact.
Grounded. Rested. Renewed.
See how GroundRhythm brings the Earth's calm into thousands of bedrooms every night.
Your Body Was Built to Sleep Grounded (Modern Life Cut the Connection)
The Earth carries a mild negative charge. Rubber soles, insulated floors and raised beds keep that charge away from your skin.
The GroundRhythm Fitted Sheet brings that connection back for every hour you sleep.
Remember how calm you feel after a barefoot walk on grass or sand? That's grounding, also called earthing.
Now picture that calm all night long. No batteries, no electricity, no change to your bedtime.
The GroundRhythm Fitted Sheet is soft, light and easy to wash. It lies across your bed and keeps you grounded all night. It supports deeper sleep, calmer nerves and natural balance.
The silver weave links your skin to the Earth, so your body soaks up free electrons all night long. Most sleepers feel the difference within 3 nights.
*After Grounding
0.00 Volts

Watch Inflammation Cool Down in Minutes
— Captured on thermal imaging, before and after grounding
Before Grounding
Shoulder Region
Red and yellow hot spots show inflammation, tension and stiffness building across your shoulders.

Shoulder Region
Cool blues and greens take over. Less swelling, better circulation and relaxed shoulder muscles.
Before Grounding
Knee Region
Heat clusters around the joints. That's why every step feels stiff, sore and tiring.

Inflammation drops to calm, even tones. Your knees feel looser and move with more ease.

What the'Research Says'About Sleeping Grounded
Gaétan Chevalier, PhD
Grounding researcher · Visiting Scholar, UC San Diego
Dr. Chevalier is a Visiting Scholar in UCSD’s Department of Family Medicine and Public Health. He has studied Earthing since 2003 and has directed the Earthing Institute since it opened in 2009. His work looks at how direct contact with the Earth’s surface affects the body’s physiology. In his words, “Modern lifestyle has increasingly separated humans from the primordial flow of Earth’s electrons
James Oschman, PhD
Biophysicist · Author, Energy Medicine: The Scientific Basis
Dr. Oschman’s background is in biophysics and cell biology. He proposes that the body’s connective tissue acts as a semiconducting network linking every cell. His hypothesis is that chronic inflammation is partly driven by a shortage of free electrons in the tissues, which grounding may replenish. In his words, “Earthing is the easiest and most profound lifestyle change anyone can make

Frequently Asked Questions (FAQs)
These answers cover how a grounding mattress cover works each night. Setup details for your size come in the box with every order.
Earthing means your skin touches the ground or a cover wired to it. Many people use it to feel calm and wind down before sleep.
No, the cover does not draw any power from your home. The cord plugs into the round ground hole and carries no live power.
Yes, as long as the cord has three prongs and a working ground pin. A two-prong cord breaks the ground link, so the cover will not connect.
Yes, but direct skin contact with the grounding surface is generally recommended. Regular bedsheets may reduce electrical conductivity, depending on their material and thickness.
Follow the care instructions provided with your product. Disconnect the grounding cord before cleaning, use only recommended detergents, and avoid bleach or harsh chemicals that may damage the conductive material.
There is no real difference between the two words. People in the UK say earthing and people in the USA say grounding.
A cheap outlet tester shows if your wall outlet is grounded first. Then a multimeter touched to the cover confirms the cover is connected.
You can use your grounding mattress cover throughout the night while sleeping. Many people prefer overnight use because it fits naturally into their daily routine.
A properly designed grounding mattress cover can be used nightly when connected to a correctly grounded outlet. Always follow the manufacturer's safety instructions and avoid using damaged cords or accessories.
Experiences vary from person to person. Some users report feeling more relaxed after regular use, while others notice little or no difference. Scientific evidence for grounding's health benefits remains limited, and results are not guaranteed.

For years, I tossed and turned every night. Now I sleep deeply and wake up rested. I’d forgotten what good sleep felt like.

After my knee surgery, I had an annoying pain that would come and go. I started sleeping grounded every night, and after a few weeks, the pain was completely gone.
