The "Grounding" Port
The bottom hole of your power socket is called the "ground" port, which connects directly into the ground, underneath the earth's surface.
Socket anatomy
Your outlet
The ground port is your home's direct line to the earth. Our grounding sheets plug into it — not into a live outlet — to safely extend that connection to your body while you sleep.

Why Grounding Matters?
Grounding isn't a wellness fad — it's a foundational electrical safety standard. Since 1913, the U.S. National Electrical Code (NEC) has required grounding in residential and commercial buildings to give stray electrical current a safe path back to the earth, preventing shocks, equipment damage, and fires.
The same principle applies to your biology. Your body runs on electricity: every heartbeat, nerve signal, and muscle movement depends on precise bioelectrical activity. Just as your home's wiring needs a ground connection to run safely, your body functions best when it stays connected to the earth's natural electrical environment.
Grounding isn't a wellness fad. It's how your body was designed to run — connected to the earth.

Understanding What's Keeping You Ungrounded
In the modern age, most people live an ungrounded, indoor lifestyle. When we do go outside, we are wearing shoes with rubber soles, which prevent us from receiving the benefits of grounding with the earth.

Why it works
The Healing Power Beneath Your Feet
Walking barefoot on grass or sand feels good for a reason. Direct skin contact with the earth lets excess electrons flow from your body into the ground, restoring electrical balance.
For most of human history, we stayed grounded all day. Today we spend our time indoors, in shoes with insulating soles — separated from the earth's natural charge. Once your bare feet leave the ground, that connection ends.
Sleep is when your body does its deepest repair. Our conductive bedsheet brings the earth's connection into your bedroom — plugged into your wall outlet's ground port, not a live socket — so you stay grounded through the night, when it matters most.
The invisible issue
What Is Dirty Electricity?
You don't have to touch a wire to be exposed. Simply being near running electronics, your body can be capacitively coupled to high-voltage AC fields — allowing small currents to pass through you without a noticeable shock.
This invisible interference is called dirty electricity. You can't see it or feel it, but it spreads through your environment and into your body — keeping your nervous system from fully settling into a restorative state.
The science
Why It Matters for Sleep & Recovery
Every cell in your body depends on electrical balance. Ion gradients across cell membranes power nerve signals, muscle activity, cellular communication, and repair.
Dirty electricity adds high-frequency stress to that delicate electrochemical balance. The result: shallower sleep, lingering inflammation, more anxiety, and slower recovery.
Grounding helps restore the balance — giving your cells the grounded environment they need to relax, repair, and recover. Peer-reviewed research (Oschman et al., Journal of Inflammation Research, 2015; Chevalier et al.) has documented improved relaxation, reduced inflammation markers, and better blood flow in grounded participants.

Frequently asked questions
Everything you need to know before your first grounded night.
How do I wash my Yonwold grounding sheet?
Machine wash at 30°C (cold) and wash separately. Do not use fabric softener or bleach, and avoid high-heat drying - line dry or low heat keeps the silver fiber conductive. Follow the care card included in the box.
How do I connect it?
Plug the attached grounding cord into the ground port (the third hole) of a standard wall outlet. No outlet nearby? Connect the cord to a Yonwold Grounding Rod placed in the earth outside.
Which size should I choose?
Flat sheets: 27×52" fits crib/single, 54×75" fits twin, 60×80" fits full/queen, 76×80" fits king. Fitted sheets come in Twin, Twin XL, Full, Queen, King and Cal King with 13-inch deep pockets for most mattress depths.
How long until I notice a difference?
Effects vary from person to person. Many customers report feeling calmer and sleeping more deeply within the first few weeks of nightly use. Grounding is a gradual, cumulative practice - consistent use may support deeper sleep and relaxation.
Are these medical devices?
No. Yonwold grounding products are wellness products and are not medical devices - they do not diagnose, treat or cure any condition. If you have a health condition or use medical devices, please consult your physician before use.
What is included in the box?
Every grounding sheet ships with the grounding cord, a ground plug adapter for your region, and an instruction card. Fitted sheets and pillowcases include the same complete kit.
How is 10% silver different from 5%?
10% silver fiber has a denser conductive weave for maximum conductivity; 5% silver fiber offers dependable everyday grounding at a lighter price. Both are woven into the same soft organic cotton — and both are covered by our 90-night trial and 5-year warranty.
Is it safe to use near a grounded outlet?
Yes. Your grounding sheet plugs into the ground port — the third, bottom hole of a standard outlet — which carries no live electricity. It simply connects to the earth's ground. If no grounded outlet is nearby, you can use a YONWOLD grounding rod instead.
Electronic devices can be very dangerous if they are not grounded.
The same goes for the body.
