Grounding Flat Sheet, Organic Cotton with Silver Threads
Most of us in Norway live and sleep cut off from the ground. This jordingslaken puts the connection back every night, through a grounding spike in the soil or your home's earth, without changing how you sleep.
What does a grounding sheet actually do?
A grounding sheet is a bedsheet woven with silver threads and connected by a cord to a grounding spike in the soil, or to your home's earth. While you sleep, your skin rests on a surface at earth potential, the way it would be on bare ground. I have slept on mine every night for over three years.
We have drifted a long way from the ground
Think about the last time your bare skin touched the ground. Not a deck, not a tiled floor, the ground itself. For most people I talk to in Norway, especially through mørketid, the honest answer is months ago.
For almost all of human history, people walked barefoot and slept on the earth. Today we wear rubber soles, sleep on foam above the floor, and live in sealed, well-insulated buildings. Each one is sensible on its own. Together, they cut us off from the ground almost completely.
Rubber soles
Every step you take is insulated from the earth.
Raised beds
Foam and wood between your skin and the ground, all night.
Sealed buildings
Homes built to keep the cold out also keep you apart from the earth.
Mørketid
Months when going barefoot outside is simply not an option.
I run this shop, so weigh my words accordingly. But I believe being this detached from the ground, for this long, is not a good thing, and I think we should do something simple about it. A grounding sheet is the easiest way I know to reconnect, every night, whatever the weather.
We need to be grounded. Let's start tonight.
Hva er et jordingslaken?
Et jordingslaken er et laken vevd med sølvtråd som kobles med en ledning til en jordingsspyd i bakken eller til jordingen i stikkontakten. Når huden hviler mot lakenet, har kroppen samme elektriske potensial som jorden, slik den har når du går barfot ute. Jeg bruker mitt hver eneste natt, koblet til en jordingsspyd.
Jording for norske soverom
The silver threads carry the earth's potential to your skin, whether the cord runs to a grounding spike in the soil or to your home's earth connection. This flat sheet lies over your existing bedding, so you keep your mattress, your duvet and your habits. If you would rather have something that fits like a normal sheet, the grounding fitted sheet is also REACH-tested, with deep pockets for mattresses up to 40 cm.

How I use mine
Across the foot of the bed, so my feet are always grounded
I lay the sheet crosswise over the foot of my double bed. At 232 cm long it spans the full width of a double bed, so both feet rest on it all night, however I turn. The rest of my bedding stays exactly as it was. If you want more of your body in contact, lay it along the bed instead.
Connected to a grounding spike, not the wall plug
I do not use the outlet. I connect my sheet to a grounding spike (jordingsspyd) with cable driven into the soil, so the sheet is connected to the ground itself. That is my own preference. If you would rather use an outlet, a plug socket tester (stikkontakttester) shows in seconds whether it is earthed.
What has been tested, and why it matters here
Grounding works through bare skin, so this is a sheet you deliberately lie on, skin to fabric, warm, for seven or eight hours a night. Softness tells you nothing about what finishing chemicals are left in the cotton, so I wanted lab results rather than a promise.
Lab-tested against REACH
REACH is the EU chemicals regulation, and it applies in Norway through the EEA. It restricts hazardous chemicals in products and keeps a candidate list of substances of very high concern (SVHC). This fabric has been lab-tested against REACH requirements, and I keep the test report on file.
Your right to ask
Anyone buying a product in Norway can ask the seller whether it contains more than 0.1% of a substance on that list, and must get an answer within 45 days. That applies to every seller, not just me. I usually answer the same day.

How it works
1. The earth holds a steady charge
The earth maintains a stable electrical potential with a large supply of free electrons. Bare skin on the ground, or a conductive connection to it, puts your body at that same potential.
2. Silver threads in organic cotton
Silver is highly conductive. Woven throughout the organic cotton, it creates a conductive surface across the whole sheet, so any skin contact connects you.
3. Connected to the earth
The sheet connects to the earth either through a grounding spike (jordingsspyd) driven into the soil, which is how I use mine, or through the earth contact of an earthed Norwegian outlet. Only the earth connection is used. The sheet is not connected to live or neutral.
4. Your body joins the connection
When bare skin touches the sheet, your body is held at earth potential for as long as you lie on it. What that does for you is the subject of the research below.
What people report, and what the research has looked at
Sleep quality
Small studies report better subjective sleep with grounding. It is the reason I first looked into it, and it pairs well with circadian light management.
Inflammation markers
Some studies report lower inflammatory markers in grounded subjects. The proposed mechanism is that free electrons act like antioxidants. This area needs more research.
Stress and cortisol
Small studies suggest a more normal day and night cortisol rhythm, along with lower reported stress. Early findings, not settled science.
Circulation
A few small studies report changes in blood flow and blood viscosity in grounded participants. Interesting, but too limited to draw firm conclusions.
Comfort and recovery
Some participants report less soreness and discomfort, including after exercise. Individual responses vary a lot.
Daytime energy
Some people report more energy and clearer mornings once grounding is a nightly habit. Effects tend to build over weeks, not nights.
The science, and its limits
Grounding has been studied for about two decades. A 2004 paper in the Journal of Alternative and Complementary Medicine looked at cortisol and sleep, and a 2015 review in the Journal of Inflammation Research discussed inflammation. Other small studies have looked at circulation and stress.
Most of this research uses small groups, and several papers share authors. Larger independent trials are still needed. The idea that electrons from the earth work like antioxidants is plausible, but it is not proven.
I would rather you buy this with realistic expectations than with a promise I cannot keep. Individual responses vary. Not a medical device.
Why I think this matters in Norway
Mørketid
Months of darkness and cold mean months without bare feet on the ground. A grounding sheet works at night regardless of what the weather is doing outside.
Well-insulated buildings
Norwegian homes are built to keep the cold out. The same construction separates us from the earth. A connection to the earth, through a spike in the soil or your outlet, bridges that gap while you sleep.
Søvnproblemer
If you struggle with søvnproblemer, grounding is one piece, not a cure. I pair it with sirkadisk belysning and blålysbriller: light protects the melatonin signal, grounding restores the earth connection.
Organic cotton with silver threads
- Organic cotton, soft and breathable against your skin all night
- REACH-tested, lab-tested against the EU chemicals regulation that applies in Norway
- Pure silver threading throughout, for conductivity across the full sheet surface
- Silver in the weave, a metal widely used in textiles to limit odour between washes
- Machine washable with mild, bleach-free detergent at max 40 degrees C
- 92 x 232 cm, long enough to run the full length of a bed, or to lie crosswise over the foot of a double bed
Setup takes a few minutes, then it just works
- Place the sheet on your mattress, over your existing bedding, or crosswise over the foot of the bed if you want your feet grounded
- Connect the cord to the snap on the edge of the sheet
- Choose your earth connection. Connect to a grounding spike (jordingsspyd) driven into the soil, which is how I do it, or plug into an earthed Norwegian outlet. With an outlet, only the earth contact is used
- Test the outlet (optional, outlet users only). A plug socket tester (stikkontakttester) confirms it is earthed
- Sleep with bare skin contact. Any contact point works: feet, arms, legs. You do not need to sleep uncovered
Norwegian-specific notes
- Standard Norwegian outlets are earthed, so the outlet option works directly
- The sheet connects only to earth, never to live or neutral
- If your outlet is not earthed (older buildings), or you simply prefer to connect to the ground itself, a grounding spike (jordingsspyd) driven into garden soil is the alternative
- Before driving a spike into the ground, check the spot for buried cables or pipes
- Disconnect the cord before washing
Care instructions
- Wash every 1 to 2 weeks in warm water, max 40 degrees C
- Mild, natural detergent only. No bleach, no fabric softener, no whitening agents, as these degrade the silver threads
- Line dry or tumble dry on low heat. High heat damages silver threads
- No ironing required, wrinkles do not affect conductivity
- Do not dry clean, the chemicals damage the silver
- Silver threads wear gradually over years of washing. Following these steps gives the sheet the longest life
What's included
Sold separately: the grounding spike (jordingsspyd) with cable and the plug socket tester (stikkontakttester).
From Dominic
I came to grounding the way most people do, through sleep. I was already working with circadian light and kept finding grounding in the research alongside it. The mechanism made sense, the early studies were interesting enough, and I added it to what I stock. I have slept grounded for over three years now.
In Norway I think it matters even more. We are well insulated from the weather, which also insulates us from the earth. Whole months can pass without bare skin touching the ground. The sheet is the practical answer: set it up once and it works every night without you thinking about it. Because you lie on it skin to fabric, I only stock grounding bedding that has been lab-tested against REACH.
If you want the full picture, I would start with blålysbriller in the evening to protect melatonin, sirkadisk belysning for room light, and grounding bedding for the earth connection. Write or text me any time with questions.

Vanlige spørsmål / Frequently asked questions
What is a grounding sheet (jordingslaken) and how does it work?
A jordingslaken is bedding woven with conductive silver threads and connected by a cord to the earth, either through a grounding spike in the soil or through the earth contact of your home's outlet. When bare skin touches the sheet, it is held at the same electrical potential as the earth, which is the contact humans had before shoes and raised beds. Small studies report effects on sleep, cortisol and inflammation markers, and more research is needed.
Does grounding (jording) work in Norwegian apartments?
In most, yes. Norwegian homes have earthed Schuko outlets, and the cord connects only to the earth contact, not to live or neutral. A plug socket tester (stikkontakttester) will confirm that your outlet is earthed. If your outlet is not earthed, or you prefer to connect to the ground itself, a grounding spike (jordingsspyd) in the soil is the alternative.
What does the research on grounding actually show?
Researchers have published a number of small studies on grounding, covering cortisol rhythm, sleep, inflammation markers and circulation, including papers in the Journal of Alternative and Complementary Medicine and the Journal of Inflammation Research. Results are encouraging, but samples are small and larger independent trials are still needed. Individual responses vary, and a grounding sheet is not a medical device.
Is a grounding sheet safe to use?
The sheet connects only to earth, either through a grounding spike in the soil or through the earth contact of an outlet, so it is not connected to live mains current. If you use an outlet, check that it is earthed first. Disconnect the cord before washing and during thunderstorms, and do not use the sheet in wet conditions. If you have a pacemaker or another implanted electrical device, speak to your doctor first.
Can I use regular sheets on top of the grounding sheet?
For the full effect, bare skin should touch the grounding sheet directly. Thin cotton may conduct a little, but direct contact works best. Treat the grounding sheet as the surface you lie on, and put your duvet over it.
Flat sheet or fitted sheet, which should I choose?
The flat sheet, 92 x 232 cm, lies over your existing bedding and is easy to move between beds. The grounding fitted sheet has deep pockets for mattresses up to 40 cm and stays in place all night. Both are REACH-tested and work on the same silver-thread principle, so choose by how you like your bed made.
Should I connect the grounding sheet to a spike or a wall outlet?
Both work. A wall outlet is the simplest option if it is earthed, and a plug socket tester (stikkontakttester) confirms that in seconds. I use a grounding spike (jordingsspyd) driven into the soil instead, so my sheet is connected to the ground itself rather than to my home's wiring. Choose the spike if your outlet is not earthed or you prefer that approach.
Can I use the grounding sheet just for my feet?
Yes. Any skin contact is enough, so you can lay the sheet crosswise over the foot of the bed and keep your feet on it. At 232 cm long it spans the width of a double bed. I sleep this way myself, with my usual bedding for the rest of me. If you want more of your body in contact, lay the sheet along the bed instead.
Hvor mye hudkontakt trenger jeg for at jording skal virke?
All bar hudkontakt er nok. Føtter, legger, armer eller rygg mot lakenet gjør at elektronene kan gå over i kroppen. Du trenger ikke sove uten dyne eller endre hvordan du sover. Mange sover i vanlig pyjamas med bare armene eller føttene mot lakenet.
Hvor lang tid tar det før jording virker?
Mange opplever bedre søvn i løpet av de første nettene, mens andre merker en gradvis endring over to til fire uker med bruk hver natt. Resultatene varierer fra person til person, så gi det minst tre uker før du trekker en konklusjon.
Hvor kjøper jeg jordingslaken i Norge?
Du kan bestille jordingslaken direkte fra Home Light Therapy her på lighttherapy.no. Vi sender fra Drammen, så du slipper importavgifter, og du har 30 dagers åpent kjøp. Vi selger også jordingsspyd og stikkontakttester. Du kan betale med Vipps eller Klarna. Har du spørsmål før du bestiller, send en e-post til admin@lighttherapy.no.
Kan jordingslaken vaskes, og hvor ofte?
Ja. Koble fra ledningen først, og vask lakenet hver uke eller annenhver uke på maks 40 grader med mildt, blekefritt vaskemiddel. Ikke bruk tøymykner, for det kan ødelegge sølvtrådene. Heng det til tørk eller tørk det på lav varme. Du trenger ikke stryke det, og det skal ikke renses kjemisk.
Kan et jordingslaken hjelpe mot søvnproblemer i mørketiden?
Noen små studier tyder på bedre opplevd søvnkvalitet med jording, men forskningen er begrenset, og resultatene varierer fra person til person. Et jordingslaken er ikke en behandling. Jeg anbefaler å kombinere det med blålysbriller om kvelden og sirkadisk belysning, og å gi det minst tre uker før du vurderer effekten.
Hva betyr det at jordingslakenet er REACH-testet?
REACH er EUs kjemikalieregelverk, og det gjelder også i Norge gjennom EØS. Det begrenser helse- og miljøfarlige kjemikalier i produkter og har en liste over særlig bekymringsfulle stoffer (SVHC). At lakenet er REACH-testet, betyr at tekstilet er analysert i laboratorium mot disse kravene. Du har også rett til å spørre enhver selger om et produkt inneholder mer enn 0,1 % av et slikt stoff, og få svar innen 45 dager.
Hva er en jordingsspyd, og trenger jeg en?
En jordingsspyd er en spyd som settes ned i bakken og kobles med kabel til jordingslakenet, slik at lakenet får forbindelse med jorden i stedet for med stikkontakten. Du trenger den hvis stikkontakten ikke er jordet, eller hvis du foretrekker å koble til selve bakken. Jeg bruker selv spyd i stedet for støpsel. Sjekk først at det ikke ligger kabler eller rør i bakken der du setter den ned.
Kan jeg bruke jordingslaken bare til føttene?
Ja. All hudkontakt er nok, så du kan legge lakenet på tvers ved enden av sengen og ha føttene på det hele natten. Lakenet er 232 cm langt og dekker hele bredden på en dobbeltseng. Slik bruker jeg det selv, med vanlig sengetøy ellers. Vil du ha mer kroppskontakt, legger du lakenet på langs i stedet.
