Reconnect to the earth. Sleep deeper, recover faster.

Grounded sleep & recovery

Four reasons people ground every night.

Whatever you're hoping to feel, here's how reconnecting to the earth helps.

Deeper sleep

Drift off, stay asleep

Designed to support deeper, more restorative sleep — so you wake feeling more refreshed.

Faster recovery

Wake up less worn down

Many people report feeling more recovered and less run-down after grounded nights.

Calmer & centered

Settle into rest

Grounding may help your body ease into a calmer, rest-and-digest state at the end of the day.

Natural & clean

Non-toxic by design

Organic cotton and silver fibers — breathable, naturally antimicrobial, and free of harsh chemicals.

What is grounding?

How grounding works

Your body is electrical — grounding reconnects it to the earth's natural charge while you sleep.

The EarthHolds a natural charge
Your outletGround port taps into it
Sheet or matSilver fibers conduct it
You, asleepAbsorb it all night
Set up in under 2 minutes

Three steps, then sleep

No routine to learn — make your bed, plug in, and rest.

Step 1

Dress your bed

Put the grounding sheet or mat on your mattress.

Step 2

Plug it in

Connect the cord to your outlet's ground port. No electricity flows through it.

Step 3

Sleep grounded

Get in bed and sleep. The ground checker confirms it's on.

The questions people ask first

Both connect you to the earth the same way — it's about how you'll use it. Choose the sheet if you want grounding built into a premium organic-cotton fitted sheet you sleep directly on. Choose a mat if you'd rather keep your own bedding and simply lay it under your fitted sheet — it grounds you through the cotton, no skin contact needed. Many people start with a mat and add a sheet later.

Grounding (or earthing) connects your body to the earth's natural electrical field through conductive silver or carbon fibers. The cord plugs into the ground port of a standard outlet — no electricity flows through it, only the earth's free electrons. It mimics the effect of standing barefoot on the ground, from the comfort of your own bed.

Yes, it's completely safe. No electrical current flows through a Grooni sheet or mat — the cord connects only to the earth-ground of your outlet, the same safety system that protects your appliances. A built-in safety resistor adds an extra buffer. Thousands of people ground every night without issue.

Grounding has a growing body of peer-reviewed research exploring effects on sleep, cortisol, and the body's natural recovery. Most studies are small-scale and the science is still emerging, so results vary from person to person. Many Grooni customers report noticeable improvements in sleep depth and morning energy within the first couple of weeks of consistent use.

Skin contact gives the strongest effect, but you don't need full-body contact — bare feet, legs, or arms are enough. Sheets are made for direct contact; bed mats work through a thin cotton sheet. If you wear pajamas, choose natural fibers like cotton or linen rather than synthetics.

Yes — Grooni grounding sheets and mats can be purchased with pre-tax HSA/FSA funds at checkout via Truemed, effectively lowering the cost by roughly 20–35% depending on your tax bracket.
