No more 3 a.m. Nothing to swallow.
Just sleep on it.

Different question than the one you’re asking. Melatonin gave you a dose, and your body did what bodies do with doses. This doesn’t give you one. It connects you to the ground wire under your house while you’re already lying still the whole night. You’ve got 90 nights to find out what that does. What it won’t do is stop working in month 6 because you got used to it.

Yes. Here’s the one worth knowing. In 2025, researchers gave people either a grounded mat or a fake one, and neither the people nor the researchers knew which was which. After 31 days, a sensor measured how long each person actually slept. The grounded group slept longer.

It was a pilot, and it tested a mat, not this sheet. But it was tested against a fake, which is exactly the test that separates a real effect from a hopeful one. There’s also a study on a sheet like this one: 10 nights, triple-blind, run by university researchers with no declared commercial ties. That one measured muscle recovery, not sleep.

The electrical half isn’t in dispute at all. The sheet grounds you, and you can check that yourself with a $15 meter in under a minute.

Start with the outlet, because an outlet without a real ground is one of the most common reasons a grounding sheet does nothing. Plug in the free tester and its 3 lights tell you in 4 seconds. Grounded outlet, cord in, skin on the sheet: you're connected. After that, the proof is your nights, and that's what the 90 are for.

Give it a week. When people write about their first nights on a grounding sheet, it's often inside that week: night one for some, night two or three for others.

If yours takes longer, that's what the 90 nights are for, and we pay the postage back. Refunds open from night 30, so a slow start still gets a fair trial.

You can, and it's the same connection. The difference is when. Twenty minutes on the lawn happens in daylight. 3 a.m. happens in bed, and that's where the sheet is: connected the whole night while you sleep, with nothing to remember.

No. You need some skin on it, not all of it. An arm, your feet, a shoulder, that’s contact. Put it on top of your fitted sheet and sleep the way you already sleep. It’s cotton with silver woven through it, not a plastic mat you have to negotiate with, and bare skin against the fabric is how the sheet in the 2019 trial was used.

Fair. Here’s the arithmetic. A bottle at $12 a month is $144 a year, and the dose has been climbing for 4 years. This is $92 once, and there’s no year 2. You’ve already spent more than this on the thing that stopped working.

No. You pay once, $92 for one sheet or $158 for two, and that's the only charge. Nothing renews, nothing ships again unless you order it, and the free gifts don't sign you up for anything.

Processing takes 1 to 3 business days. Delivery is 7 to 10 business days in the United States and 7 to 14 internationally. You get a tracking number by email the moment it leaves, and if anything goes wrong on the way, write to Support@thegroundport.com and we'll chase it with you.

90 nights from the day it arrives. Refunds open from night 30, because a sheet you slept on twice hasn't really been tried.

Email us first and a person replies within 1 business day. Send the sheet back and photograph the postage receipt: we refund what you paid for the sheet plus that postage, even if you've slept on it. 1 refund per customer, household or payment method. If your outlet has no real ground and none within reach of the cord does either, we refund right away, without the 30-night wait, and the postage back is yours.

The rest, including what happens to the free tester and mat, is in the full policy. 

Yes, and the reason’s worth understanding. The cord only ever touches the ground port, the round hole at the bottom of the outlet, which carries no electricity. It’s the safety wire, the path the electrical code requires in every new American home precisely because it’s the safe way to earth. The cord also has a resistor built in, which limits current regardless of what happens upstream.

No. A non-contact voltage pen reacts to nearby metal and static charge, which is why it glows over an unplugged sheet in the videos going around. It isn't a grounding test. That's exactly why we don't ship one. Every box gets a real plug-in outlet tester instead: 3 lights that read the actual wiring behind the wall. Test the sheet itself with a multimeter. If a company hands you a tool that lights up no matter what, that tool is decoration.

Some do. It comes down to when the silver goes on. Coat a finished fabric and the wash starts scrubbing it off from the first cycle. Ours goes on the thread before the thread is woven, so the silver sits inside the weave, where the drum has far less to grab. Wash it cold every couple of months, line dry, skip the softener.

Check it any time: multimeter on continuity, both probes on the fabric. Not through the cord. The safety resistor in it keeps a meter silent, on our cord and everyone else’s.
