How it works · BETTER3 Anti-Stress Bedroom

Four physical principles, one calm body

The Anti-Stress Bedroom does not change your body. It changes the conditions under which your body regenerates itself every night. Four physical principles are responsible for this: shielding, earthing, light-active minerals and warmth. On this page we explain what actually happens in the textiles and in the Regeneration System, what has been measured, and what users report about it.

The four principles

Passive every night, active whenever you choose

Three principles work in the bed without you having to do anything. The fourth you use deliberately, lying down, for 30 to 45 minutes a day. Each is based on a simple physical process.

01 · Shielding · Anti-Stress Duvet

A shielding plane above the body

Mobile networks, Wi-Fi and Bluetooth work with high-frequency electromagnetic fields. They are part of our everyday lives, at night too. The Anti-Stress Duvet contains two layers of a shielding fabric that reflects and attenuates such fields. Together they form a closed, shielding plane above your body, every night, without electricity and without you having to adjust anything.

What happens physically

The fabric contains conductive fibres. High-frequency fields in the range of 450 MHz to 6 GHz are reflected and attenuated at this plane instead of reaching the body beneath the duvet.

What has been measured

99.98 % shielding attenuation, university-confirmed and certified. Independent expert report by Prof. Dipl.-Ing. Peter Pauli in accordance with ASTM D4935-18, IEEE 299-06 and NSA-94-106, measured from above, below and the sides.

What has been measured is the shielding of the textiles. What that means for your sleep is something only your own test can tell. Many users describe the feeling of being pleasantly and safely enveloped in the duvet, and a calmer sleep. These are self-reports, not measured values.

02 · Earthing · Anti-Stress Underblanket

Connected to the potential of the earth

Anyone walking barefoot across a meadow is electrically connected to the earth. In homes with plastic soles, carpets and mattresses, this connection is usually interrupted. The Anti-Stress Underblanket restores it while you sleep: a conductive layer in the underblanket is connected to the earth's potential via an earthing cable. Anyone lying on it is earthed (grounded).

What happens physically

In everyday life, an electrical voltage builds up between the body and its surroundings. Through the conductive layer, potential equalisation takes place: the body adopts the potential of the earth, and excess charge flows away.

What the literature says

The book “Earthing, Heilendes Erden” describes earthing as physical voltage equalisation, particularly in the context of sleep. An intervention study with 60 participants described in the book reports improvements in sleep and well-being, which the authors themselves regard only as indications.

Potential equalisation is physics. Whether and how you perceive it is individual. Users report that they settle down more easily and sleep more restfully. Studies on earthing provide context, they do not prove any product effect.

03 · Light-active minerals · Anti-Stress Underblanket

Warmth that comes back to the body

Your body gives off heat every night, a large part of it as infrared radiation. In an ordinary mattress, this energy is lost. The Anti-Stress Underblanket contains a fleece with light-active minerals (CELLIANT). These minerals absorb the heat given off and return it to the body as infrared. A cycle that works without electricity and lasts all night.

What happens physically

The minerals are embedded in the fibre. They absorb the body's thermal radiation and radiate it back in the infrared range instead of releasing it into the room.

What the research says

Studies link textiles with light-active minerals to local tissue oxygenation (TcPO2). The material can thus contribute to blood circulation in the skin. The manufacturer's overview of studies is publicly available.

This re-radiation is a material property. What users describe is a pleasantly warm, dry feeling when lying down that does not overheat: the ICE climate fabric in the underblanket absorbs excess heat and releases it again when you cool down.

04 · Warmth and rest · Regeneration System

Lie down, warm up, come to rest

The first three principles work passively, every night. The fourth you use actively: the Regeneration System is a surface to lie on during the day. You lie on it for 30 to 45 minutes, the surface gives off gentle warmth, and you do nothing during this time. No screen, no task, just lying down. This combination of warmth and deliberate rest creates the conditions under which the body can switch from the day into regeneration.

What happens physically

The surface delivers warmth in the infrared range to the body. Warmth relaxes muscles and tissue, and lying down lets the body come to rest. Together, the two are simple, well-understood physiology.

What the literature says

The book “37°” by Uwe Karstädt describes why a stable body temperature is regarded as a reference point and why periods of rest are understood as windows for regeneration. It provides context, it does not prove any product effect.

Users describe the gentle warmth and the soft pulsing as pleasant and soothing, and many use the 30 to 45 minutes as a fixed point of rest in their day. Whether the Regeneration System is right for you is something only using it will show, which is why a 180-day right of return is included.

Putting it in context

What is measured, what is experience

We draw a clear line. Part of what you have read on this page has been measured. Another part is described in the literature. And a third part is what individual people have experienced. These three levels are not the same, and we do not mix them.

Level 1

Measured

The shielding attenuation of the textiles: 99.98 % in the range of 450 MHz to 6 GHz, university-confirmed and certified. The only externally tested value, documented in the expert report of October 2022. We will gladly send it to you on request.

See the measured value and expert report
Level 2

Described in the literature

Earthing as voltage equalisation, warmth and body temperature, textiles with light-active minerals and tissue oxygenation. Books and studies explain the principles. They provide context, they do not prove any effect of our products.

See books, studies and sources
Level 3

Experienced

Calmer sleep, falling asleep more easily, a pleasant feeling when lying down, more energy in the morning. That is what guests and customers from partner hotels and at home report. Personal experiences and self-reports, not medical statements. Every body responds differently.

We make no promises of cures. We explain what happens and let you test it for yourself.

Our products are not a treatment and do not replace medical advice. Studies on individual materials and principles provide context, they are not promises of effect for our products.

Your next step

You now know the physics. The rest you test for yourself
