Your quality of sleep makes all the difference!

Are you still asleep, or are you already regenerating?

Sound sleep at night – an energy boost during the day. What was once effortlessly provided by nature is now harder to attain, challenged by shifts in our lifestyle and environment. Our findings reveal that despite getting adequate sleep, many people still don’t feel refreshed in the morning. That’s because sleep and healthy sleep are two very different things — regardless of how many hours you rest. 

At BioRelax, we are convinced that the nocturnal increase in cellular energy is what truly transforms sleep into regenerative sleep. During the day, the body’s own energy production is under immense strain, and our mitochondria — the powerhouses of our cells — can suffer damage as a result. This leads to a drop in energy levels. 

If our mitochondria are not properly regenerated and rebuilt overnight, the "batteries" remain depleted or are only partially replenished. Without sufficient regeneration during sleep, long-term health issues can arise, affecting both body and mind. 

During a perfect night’s, regenerative sleep, our approximately 40 trillion cells have the opportunity to stabilise, repair, and renew themselves. So we wake up feeling refreshed and energised — a truly wonderful feeling. 

The award-winning active principle of the Kleinsche Fields technology leverages alternating magnetic fields. It is based on the biophysical laws of nature. Through Kleinsche Fields, we aim to support healthier cell function, optimise the body’s natural energy production, and promote self-healing processes — like a natural recharging and regeneration station for the body.

Areas of application for Kleinsche Fields

Sleeping mat
Sleeping mat
Die erfolgreichste Anwendungsform, da die Kleinsche Felder Wirkung auf großer Fläche den gesamten Körper für viele Stunden erreicht. Wie eine natürliche Ladestation für den Körper sollen die Zellen mehr Energie "tanken" bzw. generieren. Der nächtliche Schlaf ist die wichtigste Regenerationszeit für den Körper – egal ob bei der Behandlung von Erkrankungen oder zur Stärkung der eigenen Gesundheit und Leistungsfähigkeit. Das Schlafen auf Kleinschen Feldern ist so einfach wie genial – die Schlafmatte macht alles von allein. Jede Nacht. Ohne dass Sie an etwas denken müssen. Eine neue Dimension der Erholung und der Gesundheitsvorsorge mit dem Ziel täglich fitter, ausgeruhter und leistungsfähiger zu sein.

Die besondere Alltagshilfe mit dem Ziel der Unterstützung der Durchblutung und Zellversorgung. Viele Menschen leiden auf Grund von mangelnder Durchblutung und Zellversorgung unter kalten Füßen, Schmerzen, Schwellungen und Missempfindungen. Weiter sollen die Einlegesohlen über die Fußreflexzonen die Nerven zum Gehirn stimulieren für eine bessere Konzentrations- und Reaktionsfähigkeit sowie die Motorik (Bewegungssteuerung). Besonders im Alter für die Sturzprophylaxe oder zur Leistungsförderung im Sport können die Einlegesohlen helfen. Erleben Sie diese Innovation sowohl in jedem Schuhmodell (auch Hausschuh) oder bei Bedarf im Strumpf.

Optimal für Menschen geeignet, die viel Zeit im Sitzen verbringen – sowohl während der Arbeitszeit, als auch zu Hause. Ziel ist die Unterstützung der Durchblutung in der Rückenmuskulatur, um Verspannungen und Schmerzen vorzubeugen. Zudem sollen Kleinsche Felder die Aktivität des Gehirns fördern für leichtere und tiefere Entspannung und mehr Konzentration. Die einfache Anwendung auf Stühlen und verschiedenen Sitzmöbeln entspricht dem gleichen Prinzip, wie dem der Schlafmatte. Nutzen Sie die viele Zeit im Sitzen für die Gesundheit!

"Because I’m highly sensitive, I expanded the bed pad in three stages and was able to sleep fully on it after just three days. I regularly feel tingling, warmth, and pressure in the blood vessels throughout my body—areas that feel like they’re coming alive again. ... Now I fall asleep very quickly and stay asleep much longer. Before, I used to wake up repeatedly from pain caused by poor circulation in every area I was lying on."

The brain is tidied up during sleep
Sleep is essential for survival — especially for our brain. It’s not just about taking a break; sleep allows us to process and store memories, regenerate nerve cells, and, most importantly, clear out "rubbish". During sleep, the brain actively cleanses itself of the harmful metabolic waste that accumulates during the day.(10) However, not all sleep is the same. Research suggests that particularly restful sleep plays a key role in the true regeneration of our nerve cells — making it crucial for our overall health.

Successful with Kleinsche Fields
Clinic Manager Ulf Wiechel: "We are grateful to be able to use Kleinsche Fields for our patients, both during treatment and in their everyday lives. It’s not just us personally who notice more energy and strength from sleeping on Kleinsche Fields — we have even been able to further improve our already excellent treatment results with their help. That’s why we use them in a variety of ways: on our therapy beds during treatments, and in guest rooms on request, so that patients can benefit as much as possible. For us, this represents significant added value for our patients and an indispensable addition to our treatment concept — something that visibly inspires those we care for. It speaks for itself that many of our patients choose to continue using Kleinsche Fields at home on a daily basis, in order to maintain and build on their positive experiences with the Kleinsche Fields sleeping pad. We can therefore wholeheartedly recommend them!" Further information: www.swissmountainclinic.com.

FAQ

BioRelax products are already world leaders in their category. Their unique active principle — based on nature and operating without electricity, devices, or electrosmog — is increasingly seen as the technology of the future. We combine our cross-sector expertise in medicine and naturopathy not only in our products but also in our personalised advice. The opportunity to access the full knowledge of specialists from both research and practice — directly from the manufacturer — is a unique service for many. Especially in today’s often confusing health landscape, we support our customers as trusted advisors, helping them make the right choices for their individual needs.

  • Older adults aged 50 and over who want to counteract physical decline and reduced cell function, and stay healthy, symptom-free, and vital for longer
  • People experiencing physical or mental complaints or illnesses
  • Healthy individuals looking to strengthen their wellbeing with natural extra energy and improved everyday performance
  • Professional and amateur athletes seeking to enhance their performance and promote more effective regeneration
  • Working people to increase concentration, reduce stress and improve well-being
  • Haustiere zum Erhalten der Vitalität, Beschwerde-Behandlung und zur Unterstützung der Körperfunktionen

BioRelax Products Are Successful in Various Areas of Application.

Strengthening Health and Regeneration:

When cell performance and regeneration are naturally supported, it helps to strengthen overall health, enabling individuals to stay fit and healthy for as long as possible despite various environmental stresses — and to prevent complaints or illnesses from developing.

Treat complaints and illnesses:

If symptoms or illnesses are already present, improved cell performance and regeneration can help the body to resolve these symptoms more effectively and improve illnesses.

Physical and mental performance:

Physical and mental performance is important every day, both at work and in sport. BioRelax products with their special effect can help with various performance factors for more energy, success and well-being.

We are convinced that people who do not actively support their cellular performance cannot maintain 100% health. Complaints and illnesses may also develop earlier. 

It is no longer a secret that the stresses and strains of everyday life have increased dramatically across all age groups — and are set to rise even further. Hardly any body can function completely healthily under today’s conditions. The body requires and consumes a significant amount of energy to cope with these stresses.  

As a result, the cells often lack the necessary performance and energy production. We then feel tired, weak, and exhausted, or experience common everyday complaints such as tension, headaches, sleep disturbances, or pain. 

If the cells are deprived of sufficient energy over a longer period, chronic illnesses may even develop. 

BioRelax with Kleinsche Fields is the right choice for those who wish to sustainably strengthen their physical and mental health in a natural and gentle way. 

BioRelax is the world’s No. 1 in its category. The combination of multiple factors makes BioRelax truly unique for many peopl.
