Kleinsche Fields Explained Simply
Permanent magnets are considered an inexhaustible force of nature. This natural power is also harnessed in BioRelax products in the form of Kleinsche Fields.This gentle medical technology was created over 30 years ago, inspired by the Earth's vital magnetic field. What makes Kleinsche Fields so special is the complex arrangement of alternating north and south poles, creating a natural and effective permanent magnetic field without the use of electricity. The special mode of action of Kleinsche Fields technology is based on the interplay of various field factors — such as strength, distance, and the size of the polarities. The result is alternating polarity magnetic surfaces with a low, gentle magnetic field strength. Thanks to their unique design, Kleinsche Fields are able to reach the upper layers of tissue at the cellular level, stimulating the body's natural repair processes.
Sleep for a regenerated and powerful body
The human body has enormous potential to repair cell damage and maintain health and vitality. However, for the body to regenerate optimally, its approximately 40 trillion cells must perform at their best. How well our cells function depends, among other things, on the constant movement of electrically charged particles along the cell walls. If cells lose this dynamic, they increasingly lose their function and performance.
The magnetic forces of Kleinsche Fields were developed to interact with the body’s own charged particles. They are designed to generate a gentle micro-voltage, improving the movement of ion currents. This process aims to support cell performance and promote energy production in the mitochondria — the power stations of the cells.¹–⁴
At the same time, blood circulation (micro-circulation), oxygen supply to the cells, and detoxification processes are also supported. The goal is to enable genuine regeneration during sleep, leading to more energy, strength, vitality, and well-being during the day.
Research findings
Their intended holistic effect at the cellular level is what makes Kleinsche Fields so popular — and above all, so universal in their application. After all, a good ability to regenerate is crucial for almost every aspect of our health. The effectiveness of Kleinsche Fields technology has been demonstrated through numerous testimonials from users, doctors, and therapists, as well as through measurements and scientific studies.
Prof. Dr. Brigitte König comments: »It is now well established in conventional medicine and through high-level scientific publications that mitochondria play a key role in a wide range of diseases when they do not function properly. These include Alzheimer’s, Parkinson’s, cardiovascular diseases, arteriosclerosis, circulatory disorders, diabetes mellitus, migraines, and other so-called diseases of civilisation, such as metabolic syndrome (high blood pressure, obesity, altered blood lipid levels, insulin resistance), polyneuropathy, sleep disorders, and pain. Since Kleinsche Fields have a positive influence on the mitochondria, they also have a positive impact on all of these conditions.«
(In order to be able to make general statements about the effects of various diseases, further large studies are needed to provide evidence for each individual disease. The Kleinsche Fields researchers are convinced that they will also be able to carry out these studies in the next few years).
How does "refuelling energy" work?
The balance between activity and recovery is crucial for a healthy body. Only during the nightly recovery phases can cells regenerate and renew themselves to ensure enough energy for the activities and demands of the day. Our cells are therefore highly active during the supposedly quiet night, as numerous vital processes must take place simultaneously for optimal cell renewal.
In particular, the mitochondria — the cell’s power stations — need to be repaired and replaced to ensure a vital, energetic start to the day. Sleeping on Kleinsche Fields is designed to support cellular performance and regeneration throughout the night. Like a natural charging station for the body, the cells are intended to use the many hours of sleep to "refuel", increasing their energy production and promoting the body's natural self-healing processes — night after night.
In addition to their outstanding effects, Kleinsche Fields offer numerous other advantages:
Kleinsche Fields

Natural real magnetic fields Yes, medical device Medical device class 1 (safest product class) Only the sleeping mat itself Works entirely on its own, without electricity or batteries, and never needs recharging No, cannot be created at all Cells are supported constantly, gently and naturally over many hours Kleinsche Fields do not need to penetrate the entire body to be effective No harmful side effects have been reported after more than 30 years of research; overdose is not considered possible Many own studies and measurements Simply lie down, relax, and let it work naturally. The body adjusts itself optimally without external control Works immediately and automatically when you lie on it — stress-free, relaxed rest, without effort, without the risk of forgetting Can be used permanently, without limitation Yes, children can also use Kleinsche Fields. See product description Yes, they are safe for users with metal implants and pacemakers (please refer to the product description for specifics) Germany, quality handmade according to strict medical device standards 
Power-generated artificial magnetic fields Some only wellness products Usually only medical device class 2 (higher risk and hazard class) Usually requires mat, devices, cables, sometimes batteries and other accessories Must always be operated via power connection or battery Generate electromagnetic fields Cells can or are inevitably affected by electromagnetic radiation in spurts Must or usually acutely penetrate the entire tissue of the body with radiation Side effects cannot be completely ruled out. Depending on usage, overdoses may occur quickly if there is any doubt. Often few or no independent studies are available — instead, studies from entirely different devices or software are sometimes used covertly for advertising purposes. Often complicated settings or programmes are required, making them difficult to use correctly without detailed instructions; there is a risk of incorrect use, especially in certain health conditions. Additional time must be invested for setup and operation. Use can easily be forgotten when time is short. Devices often require dedicated space or need to be set up and stored after use. May or should usually only be used for a limited time Children are sometimes excluded as users or not recommended Metal implants and pacemakers are partially excluded or not recommended. Electromagnetic fields can affect pacemakers Technology often manufactured cheaply and to low standards in Asia

Yes, the physical effect of Kleinsche Fields occurs in everyone. Regardless of age or state of health. You can therefore always be sure that Kleinsche Fields will also work for you or your fellow human beings.
It is ultimately a simple physical process, not a question of faith. If the blood moves with its + and - ions over the constantly changing + and - poles of Kleinsche Fields during circulation, a reaction must take place.
As an active principle, Kleinsche Fields vary their field strength across a given area. Depending on the product and the distance from the body, the incoming magnetic flux density ranges between 1 and 30 mT.
Measuring units at a glance:
| Unit | Value |
|---|---|
| T (Tesla) | ~ 0,001 - 0,03 |
| mT (Millitesla) | ~ 1 - 30 |
| Gauß | ~ 10 - 300 |
| uT (Microtesla) | ~ 1.000 - 30.000 |
Explenation:
The commonly used term "magnetic field strength" is technically known as "magnetic flux density". In the past, magnetic flux density was measured in Gauss units, but today it is expressed in Tesla. With a flux density of 1–30 mT, Kleinsche Fields generate a measurable field height of approximately 3 cm.
Important!
Differences from Electromagnetic Fields (EMF): Although electromagnetic fields (EMF) are measured in the same unit — Tesla — they differ fundamentally from static permanent magnetic fields. The radiation from electromagnetic fields reaches much greater distances at the same measured field strength and can have undesirable effects on the body.
The myth of magnetic field strength:
There is a common misconception that the higher the magnetic field strength, the greater the positive effect. Some dubious suppliers of magnetic products exploit this misunderstanding, suggesting that higher field strengths automatically lead to better health benefits. In reality, Kleinsche Fields operate on a different principle: gentle, natural stimulation without unnecessarily high field strengths — for safe, effective support of the body’s natural processes.
The cells of our body generate electricity through their metabolism — the essential life processes of the cell.Wherever electricity is present, a magnetic field is physically created. This means that every cell naturally possesses its own weak magnetic field. Worldwide studies have shown that weak permanent magnetic fields can have a positive influence on biological structures — both in humans and in animals.¹¹–¹³
The scientific standard work¹⁴ concludes that if a magnetic field is too strong, it may influence delicate biological structures less effectively — or may even have no positive impact at all. It appears that in such cases, the cell "shuts down". It is well established that static field strengths between 1 and 350 mT are sufficient to produce significant effects on the circulatory system, skin microcirculation, and arterial blood pressure.
For reference, the International Commission on Non-Ionising Radiation Protection¹⁵ recommends a limit value of 40 mT for homogeneous exposure of the entire body for the general population.
Commercially available magnets and various magnetic products on the market generally have significantly higher magnetic field strengths than Kleinsche Fields. However, stronger is not always better — in fact, it can sometimes mean the opposite.
Kleinsche Fields achieve their extraordinary effect without the need for high magnetic field strengths. Thanks to their special field construction, it is sufficient for them to reach only the upper tissue layers beneath the skin.Kleinsche Fields therefore represent a gentle, natural form of action — modelled on nature itself.
