Includes connection cable, EU plug adapter and both testers. Lab-tested silver thread (real silver (Ag), June 2026): details below.
We hold the laboratory report for the silver thread used in the sheet. The figures, plainly:
That thread is woven at 5% or 10% of the fabric depending on the variant: that percentage is the share of silver thread in the sheet; the thread itself is lab-tested as real silver (Ag). When comparing brands, always ask whether their "X% silver" means silver in the fabric or silver-coated thread in the fabric: almost nobody says. The full report is not published because it contains the manufacturer's details; if you need it for a professional purchase, write to us.
Set it up once and forget it. Whenever you want to check everything is still connected, run tester no. 1 over the surface.
Yes: the connection happens through your skin touching the fabric. The more skin touches the sheet — feet, legs, arms, back — the better the conduction. Full-body pyjamas leave almost no contact and reduce the effect; sleeping with bare feet or arms on the sheet is already enough.
Tester no. 2 tells you before you start: plug it in and check that the earth connection works. If that outlet doesn't have one, try another spot in the house — modern installations and kitchen outlets almost always do. Without a working earth connection, the sheet cannot ground you.

There is no new routine to learn, no posture, no schedule. You go to bed as every night and, during the eight hours you were going to spend there anyway, your skin is in contact with silver thread connected to your home's earth.
The silver thread in the fitted sheet carries to your skin the electrical potential of the building's earth connection, the same one the garden soil has. It carries no current: it equalises potentials.
Ghaly and Teplitz (Journal of Alternative and Complementary Medicine, 2004) observed changes in the night-time cortisol profile of participants who slept grounded, alongside subjective sleep questionnaires. Limit: 12 participants, no blind control group; it is an exploratory study. The 26 peer-reviewed papers, each with its DOI and its limit written beside it, are in Grounding research.
«Since I started using them I notice that I rest better and, as an athlete, I have the feeling that I recover better after training.»
Machine wash at 30 °C maximum, powder detergent, no fabric softener, no bleach, air dry. Softener leaves a film over the silver: it is the most common reason a conductive textile stops conducting. Treated that way, conductivity holds wash after wash.
Because it conducts far better from the very first use: about 63×10⁶ S/m for silver against about 1.4×10⁶ S/m for 316L steel. Steel is cheaper and does not tarnish; we prefer silver's initial conductivity and biocompatibility, and we show the numbers. The full comparison.
The cable goes to the earth pin of the socket, never to the two live poles. It puts no electricity into the fabric: it equalises your body's potential with the building's earth, the same principle as the metal casing of any appliance. A tester is included so you can check it yourself.

Vitality was not born in a laboratory, but in the personal fight of someone who refused to give up. Lucas spent three years looking for answers nobody gave him and ended up in bioelectricity; every product of the brand came out of that. The whole story.

I've been using Vitality's Grounding sheets for a while now and I'm very happy with the purchase. Since I started using them I notice a big difference, especially with menstrual pain, which has gone down considerably. On top of that, I do weight training several times a week and I feel I recover much better after the gym. For me they've been a complete success.
I've been using the Grounding sheets for two years now and I couldn't be happier. Since I started using them I notice that I rest better and, as an athlete, I have the feeling that I recover better after training. From my experience, I'd recommend them to any athlete, but also to anyone who wants to improve the quality of their rest. Highly recommended!
It had been a long time since I rested this well, and the incredible thing is that it's thanks to the Vitality sheets. Both the concept and the execution are brilliant 🙌🏼🤩
The Vitality Life Balance sheets surprised me above all for the sense of comfort they bring to rest. From the very first night you notice a soft, pleasant fabric that helps you relax as you get into bed, creating a more comfortable environment for deep sleep. They are breathable, which avoids that feeling of heat or stuffiness during the night, and that makes rest more continuous and restorative. After several uses and washes they still keep their softness, which also adds to that "fresh bed" feeling every day. All in all, they give the impression of encouraging more stable sleep and better physical recovery on waking, as if you were really helping your body rest better.
What the published studies measured, system by system, with their figures and their limits. The 3D body is illustrative: what lights up marks the topic of each card, not an effect of the product. Swipe to go through it.
Barefoot on grass, the body is at the same electrical potential as the ground. The sheet does the same in bed: the silver thread connects by cable to the ground port of the wall outlet. In volunteers, connecting a conductor to the skin lowered the body's electrical potential to about −200 mV and it returned to its value on disconnecting. The current that flows is in the nanoamps, too small to feel.
In a pilot with no placebo group described, 12 people with sleep and stress complaints slept for 8 weeks on a conductive cover connected to ground: salivary cortisol dropped significantly during the night and the 24-hour profile moved closer to the natural rhythm. Almost all reported sleeping better and less stress.
In another double-blind study, 40 adults spent an hour in a conductive armchair: positive mood improved in those who were grounded and not in the sham connection group.
In 10 healthy adults, two hours connected to ground increased the zeta potential of red blood cells (their surface electrical charge) by an average of 2.70 times in all samples, and significantly reduced the aggregation of these cells. With more charge, the cells repel each other. The authors infer from this a less viscous blood, although viscosity was not measured. These are laboratory measurements on blood samples, not clinical results.
Randomized, triple-blind trial with 22 volunteers after an intense downhill run: those who slept grounded for 10 days lost less jumping performance and less isometric strength, and their creatine kinase (a marker of muscle damage) rose less than in the sham connection group. In a preliminary analysis of 4 participants, three inflammation markers associated with muscle damage (IP-10, MIP-1α and sP-selectin) were lower.
In a 6-week double-blind trial, 16 massage therapists who worked and slept grounded reported more energy and physical function and less fatigue than in the weeks without connection; part of the effect was still there a month later.
Lower night-time cortisol, less aggregated red blood cells, less muscle damage marker and less loss of performance after exertion, more energy and better mood: that is what five of these studies recorded in grounded people, three of them while sleeping.
They are small studies, two of them pilots, and some of them by authors with ties to companies in the sector. None of them evaluates Vitality textiles. The sheet is based on the same principle they followed: conductive contact with the ground while you sleep.
The Vitality Grounding sheet contains silver thread, analyzed in a laboratory as silver (Ag), and connects to the ground port of the wall outlet with the cable and the verification tester included. No batteries or electricity: only the conductive contact with the Earth, all night.

"According to Ghaly & Teplitz (Journal of Alternative and Complementary Medicine, 2004), grounding normalised cortisol rhythm, and study participants reported improvements in sleep quality. Individual results may vary."
Considered one of the most scientifically supported wellness practices, earthing is a natural wellness practice that, according to published research, may help support rest and the body's balance, regardless of age.
The earth constantly emits free electrons. Disconnected from the ground, you miss out on them every night. The grounding sheet changes that: the silver thread conducts those electrons to your skin while you sleep. No effort. No devices. No batteries.
That's why we use silver instead of stainless steel like the competition — greater conductivity from the very first use, and you can feel it.
"According to Ghaly & Teplitz (2004), grounding during sleep normalised the circadian cortisol rhythm, and study participants reported improvements in well-being and sleep quality. Individual results may vary."
"According to Chevalier et al. (J. Environmental and Public Health, 2012), grounding may help support certain wellness markers observed in study participants. Individual results may vary."
"Research suggests that the earth's electrons may act as natural antioxidants, helping neutralise the free radicals associated with chronic systemic inflammation. Individual results may vary."
Zeta potential is the electrical charge around your red blood cells. With grounding, it improves dramatically — better blood flow, better oxygenation, better cardiovascular health. Test it yourself.
