Regenerative sleep – the best way to boost your health

Sleep is indispensable and an essential prerequisite for our health. And yet, despite getting enough hours of sleep, many people do not feel properly rested in the morning. Apparently, sleep and healthy sleep are two different things — regardless of the amount of time spent asleep. We are convinced that a nightly increase in cellular energy is what truly transforms sleep into regenerative sleep. The body’s own energy production takes place in our mitochondria — the power stations of the cells.
These can be particularly damaged by the stresses of the day, leading to a drop in energy levels. Our "batteries" then remain empty or are only inadequately recharged if the cells cannot regenerate properly during the night. Cells can only stabilise, repair, or renew themselves with optimal sleep (regenerative sleep). When this happens, waking up does not feel exhausting or paralysing — instead, you can start the day with energy and vitality. Kleinsche Fields medical technology was developed to support healthier cell function, optimise the body’s own energy production, and promote natural self-healing processes. Our 30 years of research and development have shown that regenerative sleep is often the key.

Sleep regeneratively - live better!

Kleinsche Fields for your basic health

During sleep, our body is constantly renewing itself — more precisely, our cells. Through continuous division, repair and regeneration, the trillions of cells in our body keep themselves young and, in turn, keep us healthy. Regenerative sleep is therefore the only natural state of the body that acts as a source of strength, a memory booster, and even as protection against depression, while also caring for our appearance. 

During this time, the body’s own healing processes can unfold: the immune system is strengthened and fights off pathogens, skin cells are renewed and wounds heal, muscles can regenerate, and the heart can recover. Our brain also processes the day's information during sleep, improving concentration and responsiveness. 

Our overall well-being, our appearance, and how fit and young we feel therefore depend largely on the health of our cells. When cells are optimally nourished, they maintain an active metabolism, which acts like a true fountain of youth. Active cells help the skin look fresher, boost overall metabolism, and support better detoxification. 

However, for cells to remain active day and night, they must maintain a natural micro-tension. Without this tension, they lose their vitality. The gentle magnetic fields generated by Kleinsche Fields technology have been specially designed to support the cells in maintaining their natural tension, promoting active cell metabolism and optimal cellular performance. And the more, the better. 

The BioRelax sleeping mat is designed to enhance cell performance across a large surface area and for many hours to enable regenerative sleep. For daytime support, BioRelax insoles are the ideal companion, providing energy and vitality from morning until night.

Persistently poor sleep can make you ill in the long term.

Regenerative sleep needs healthy mitochondria

On average, people spend around a third of their lives sleeping — or at least trying to sleep. Current studies show that sleep quality is declining globally. Often, our own lifestyle habits are to blame, but there are also numerous environmental factors that significantly impair the quality of our rest.

It's not just bright and artificial light in the evening or the consumption of caffeine that can disrupt the body’s natural biorhythm. High levels of stress, environmental toxins, medication, smoking, alcohol, electrosmog and particulate matter can all place stress on cell activity, cell regeneration and cell performance — and may overwhelm the body’s natural repair mechanisms.

The power stations of the cell — the mitochondria — are particularly vulnerable. If they are unable to regenerate overnight, our internal batteries stay empty, and our ability to produce energy is reduced. Mitochondria are responsible for producing the essential energy carrier ATP (adenosine triphosphate) for the cell. Without enough ATP, cells can no longer properly repair or renew themselves. They begin to age — and so does the body. In the long term, this can not only cause premature ageing but also lead to a wide range of complaints and illnesses.

BioRelax products with Kleinsche Fields technology are believed to have a positive effect on mitochondria. Renowned mitochondrial researcher Prof. Dr Brigitte König has demonstrated through studies and measurements that Kleinsche Fields can support mitochondrial regeneration and significantly increase ATP production.

For our body, this means: the more energy the mitochondria can produce, the more efficient our cells become — and the more effectively nightly repair and healing processes can take place.

Did you know that stressed cells can significantly accelerate the ageing process?

If the composition of the implant is unclear, application is considered safe at a minimum distance of 1.5 cm. At this distance, the magnetic field strength is already lower than the Earth's natural magnetic field, within which all implants are permanently located. To avoid any possible negative influence on electronic implants, a minimum safety distance of 1.5 cm should be maintained between the implant and the product.** BioRelax products with Kleinsche Fields are intended for use by children aged 10 years and older, and adults, without height or weight restrictions, within the home environment.

This top seller offers perfect comfort all day long. The insoles are less than 3 mm thin, highly flexible and can be easily inserted into any shoe. They can also be worn in socks, e.g. at night when sleeping.The scope of delivery "piece" always refers to a pair of insolesHow BioRelax Kleinsche Fields insoles work:
All nerve signals in the body are actually electrical signals that are transmitted through the body via the nerve pathways - to the brain and back again. The nerves can therefore also be influenced by the charges of the positive and negative poles of a permanent magnetic field.
 Klein fields are said to stimulate nerve signals in a gentle, natural way. This is because the electrical charge particles of the nerve signal move through alternating positive and negative charges.This interaction with the pole changes measurably activates the entire nervous system. The aim is to stimulate muscles that are located further away from the feet by networking the nerve pathways in the muscles of the body. Contact with BioRelax insoles can therefore measurably increase the muscle tension and performance of various muscle groups.Only 3 mm thin - can be worn discreetly in any shoeFully integrated small fields - no punctual application, but even coverageSuitable for all day use - whether in the office, during sport or on the goAntibacterial & washable - easy to clean and hygienicAvailable in many sizes - from 36 to 46, can be customisedYou can find lots more information and tips about the insoles in the Questions and Answers section below.

FAQ

Yes, the physical effect of Klein's 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, Klein fields vary their field strength within an area. Depending on the product and distance to the body, the incoming magnetic flux density varies between 1 - 30 mT.

Measuring units at a glance:

UnitWorth
T (Tesla)~ 0,001 - 0,03
mT (Millitesla)~ 1 - 30
Gauß~ 10 - 300
uT (Mikrotesla)~ 1.000 - 30.000

Explanation:
The commonly used term magnetic field strength is technically referred to as ‘magnetic flux density’. In the past, magnetic flux density was expressed in Gauss units. Nowadays it is measured in the unit Tesla. At 1 - 30 mT, small fields generate a measurable field height of a maximum of approx. 3 cm. 
Important!
Differences to electromagnetic fields (EMF): Even if electromagnetic fields (EMF) are measured in the same unit Tesla, they differ significantly from a static permanent magnetic field. The radiation from electromagnetic fields reaches many times further with the same measured field strength, which can have undesirable effects. 
Myth of magnetic field strength:
A misconception of ignorant people is that the higher the magnetic field strength, the greater the effect. Some dubious suppliers of magnetic products capitalise on this and suggest that high field strengths have a correspondingly positive effect on the body.
