FAQs
Grounding Basics
What is grounding?
Grounding means making a direct electrical connection between your body and the earth, like walking barefoot on grass, sand, or soil. Grounding products make that connection indoors, through the ground port of a properly grounded outlet.
What is the difference between grounding and earthing?
There's no difference. They're two names for the same thing: a conductive connection between your body and the earth.
How do grounding products work?
Each product has a conductive surface woven or built into it, and a cord. The cord plugs into the ground port of a grounded outlet, which is wired to a rod in the soil outside. When your bare skin touches the surface, you're connected to the ground. The product doesn't use the outlet's power.
Can my pets use grounding products?
Yes. Many people place a mat where their pet already likes to rest. Keep the cord out of reach of pets that chew.
General Product Questions
How do I test my sheet or mat?
First test the outlet with an outlet tester. To check the product itself, use a continuity tester or multimeter between the conductive surface and the ground pin of the cord. Our Setup Guide explains the steps.
Do grounding products give off EMFs or magnetic fields?
No. The cord connects only to the ground port, which carries no power, so the product doesn't create an electric or magnetic field of its own.
Why can't I detect continuity in the grounding cord?
Some grounding cords include a safety resistor, which a basic continuity tester can read as an open circuit. Set your multimeter to resistance (ohms) instead, and contact us if you're still unsure.
Will it work if I live in an apartment?
Yes. The ground port is wired to the building's ground connection, so it works on any floor, as long as the outlet is properly grounded.
What if my home doesn't have a grounded outlet?
Use a grounding rod in moist soil outside, with an extension cord to your product.
Can I use grounding products with a pacemaker or metal implant?
If you have a pacemaker or any implanted or body-worn medical device, ask your doctor before using a grounding product.
What plug type should I choose?
Choose the plug that fits your home's outlets: US, UK, EU, or AU/NZ. A plug adapter lets you use the same cord when you travel.
Which is better: a grounding mat or a grounding sheet?
It depends on where you spend the most time. A sheet keeps you connected while you sleep. A mat works at your desk or on the sofa. Many people use both, which is what our set is for.
Sheet Questions
How do I set up a grounding sheet?
Lay the sheet on your bed, connect the cord to the sheet, then plug it into a tested outlet. Sleep with bare skin touching it.
Which side of the sheet goes up?
The conductive side faces up, so it touches your skin. The guide in the box shows which side that is.
Why do I feel a small shock from my sheet?
That's usually static, especially in dry weather or on synthetic bedding. It isn't from the outlet. Connecting the sheet before you lie down usually stops it.
How long should I lie on a grounding sheet?
As long as you sleep. Most people use it all night.
Can I put a regular sheet over the grounding sheet?
No. The connection needs bare skin on the conductive surface, so put the grounding sheet on top.
Can I wear pajamas on the grounding sheet?
Yes, as long as some bare skin, like your legs, arms, or feet, touches the sheet.
How do I wash my grounding sheet?
Wash in cold water on a gentle cycle and air dry. Don't use bleach, fabric softener, or dryer sheets, and don't iron.
What's the difference between the half sheet and the fitted sheet?
The half sheet lies across part of your own bedding. The fitted sheet replaces your bottom sheet and covers the whole mattress.
Mat Questions
How do I clean my mat?
Wipe it with a damp cloth and mild soap, then let it dry. Don't use alcohol or harsh cleaners.
Can I wear socks on the mat?
Regular socks block the connection. Use bare feet, or grounding socks.
Can I plug a grounding mat into a power strip?
Yes, if the power strip is itself plugged into a properly grounded outlet. Test it first.
How long should I use a mat each day?
There's no set time. Many people use it for as long as they sit at their desk.
Which side of the mat goes up?
The conductive side faces up and the non-slip side goes down. The guide in the box shows which is which.
