Frequently Asked Questions

Is there any research behind grounding?

Yes, though we'd rather give you the detail than a checklist. In 2017, researchers at Penn State College of Medicine grounded 26 preterm infants in intensive care and measured heart rate variability: skin voltage fell by roughly 95% and vagal tone — a marker of nervous-system regulation — rose by about 67%, returning to baseline once grounding stopped (Passi, Doheny, Gordin, Hinssen & Palmer, Neonatology, 2017). A 2004 study had 12 people sleep grounded and tracked cortisol alongside self-reported sleep, pain and stress, finding cortisol rhythms shifted toward a normal pattern (Ghaly & Teplitz, Journal of Alternative and Complementary Medicine, 2004). A 2013 study of 10 subjects reported reduced blood viscosity after two hours of grounding (Chevalier, Sinatra, Oschman & Delany, same journal).

Now the caveats, because you'd find them anyway. These samples are small — ten to twenty-six people. Most outcomes are self-reported. Few are blinded. And the most widely 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 they are contractors for, and shareholders in, a company that sponsors earthing research.

Our honest read: the work is real, published and suggestive. It is not settled, and we won't tell you it is.

How do I know my outlet is actually grounded?

Most outlets built since the 1960s are, but not all of them, and a three-prong socket isn't proof on its own. An outlet tester from any hardware store tells you in about ten seconds. If yours turns out not to be grounded, a grounding rod run through a window solves it — email us and we'll walk you through it.

My house is old. Will this still work?

Often yes, but test first. Older homes sometimes have three-prong outlets retrofitted onto two-wire circuits with no real ground behind them. A tester settles it, and the rod kit solves it if the answer is no.

Is it safe to sleep connected to an outlet?

You're connecting only to the ground pin, which carries no current — it's the safety path electricity takes if something goes wrong elsewhere. The cord also has a built-in resistor as a second layer of protection. Nothing is powering the sheet.

How do I wash it? Does the silver survive?

Machine wash cold on gentle, tumble dry low or line dry. No bleach, no fabric softener, no dryer sheets — softeners leave a coating that insulates the silver, and it isn't reversible. That is the single most common reason a grounding sheet stops working. The silver is woven in rather than coated, so with that care it lasts the life of the sheet.

Can two people share one sheet?

Yes. Anyone in skin contact with the sheet is grounded through it. One cord serves the whole bed.

Do I need bare skin touching it?

Some skin contact is needed — an arm, a leg, a shoulder. Pyjamas covering you head to toe will block it. Most people sleep with enough skin exposed without thinking about it.

Does it go over or under my regular fitted sheet?

This is your fitted sheet. It goes directly on the mattress and you sleep on it. Putting another sheet over it defeats the point.

How long until I notice something?

It varies. Some people report a difference within a few nights, others after a few weeks.

What size should I order?

Your mattress size, as normal. The 15-inch pockets handle deep and pillow-top mattresses, so you don't need to size up for depth.

Is it safe around pets?

Yes — a grounded pet on the bed is grounded exactly as you are. Claws are harder on the fabric than on the silver.

Why do the different silver percentages cost different amounts?

Silver is the conductive element, and more of it means a stronger, more even connection across the sheet. Our 5% weave is the gentlest and where many people start, 10% sits in the middle, and 20% is the strongest we make. The fabric matters too — cotton is crisp and familiar, bamboo is the softest and sleeps coolest, Tencel is silky and the most breathable.
