The effect of radon

The Bad Brambach mineral springs have a special ingredient - radon, a rare gas of rare quality.

It is found in the granite rock and soil of the region, is odorless and tasteless and cannot be seen with the naked eye. Since it evaporates relatively quickly, radon therapies are only possible and effective near natural radon deposits, such as in Vogtland. For therapy, it can be dissolved in water or used as air containing radon.

Radon therapy has a long and successful tradition. It is used as a valuable and mild stimulus in a low dose range and usually only develops its full effect after a treatment has been completed.

When radon decays, high-energy particles are created that can eliminate dysfunction in the body. Metabolism and repair mechanisms in the cells are activated, inflammation is inhibited, the release of pain-relieving endorphins is promoted and the self-healing powers are stimulated.

A special feature of the Bad Brambach mineral springs is the naturally occurring combination of radon, a high proportion of free carbonic acid and many valuable minerals. The naturally contained carbonic acid expands the blood vessels and increases blood circulation, which leads to improved absorption of valuable radon. The minerals contained in the healing water support the utilization of radon in the body.

A treatment with radon can often reduce the use of conventional painkillers with all their harmful side effects in the long term. Sustained pain relief for up to 9 months is not uncommon.

Relieve pain with radon

In cooperation with experienced scientists, the latest findings are evaluated and implemented in the application of the natural remedy radon. The effectiveness of radon therapy has already been researched in recognized double-blind studies.

Wettin source – the strongest radon source in the world

The positive effects of this natural remedy have been known for more than 100 years, and radon cures have a long tradition in Bad Brambach.

With the Wettin spring, Bad Brambach has the strongest radon spring in the world. This is prescribed for drinking in a controlled and targeted manner. The spa doctor determines the amount, frequency and time of intake. Use the special effect of radon therapy for your health, which is naturally gentle and has no known side effects. The latest findings prove that it is highly effective, even with a low dose.

In addition to activating the metabolism and self-healing powers, radon therapy increases the release of endorphins, reduces inflammation and relieves pain. This reduces the consumption of painkillers - increasing the quality of life. A special feature of using the drug in radon therapy is that it works in a purely natural way and the relief has been proven to last several months after treatment.

Drinking cure
During the drinking cure, the radon mineral healing water enters the body via the gastrointestinal tract and thus unfolds its naturally gentle effect. The healing water is drunk regularly over a longer period of time for therapeutic purposes. The duration, the amount and the time of drinking are determined by the spa doctor. The Wettin spring in particular, with around 24.000 Bq/l radon, is considered the strongest radon source in the world.

Interesting facts about the creation of radon-containing healing water

Natural healing water is created by the slow percolation of rainwater through different geological rock layers. It is cleaned, filtered and enriched with minerals and trace elements. In this enriched deep water, carbonic acid is released by solidified magma from past volcanic activity. The noble gas radon is created from the radium contained everywhere in the earth's crust. The Bad Brambach healing springs get their health-promoting radon content from the Fichtelgebirge granite. All sources are strictly checked in accordance with the Medicines Act.

With the Wettin spring, Bad Brambach has the strongest radon sources in the world. All of Bad Brambach's healing springs: the Wettin spring, the Schiller spring, the Eisenquelle as well as the Upper and Lower Limit springs have a variety of minerals, trace elements, carbon dioxide and the noble gas radon. The valuable radon mineral healing water is offered individually in Bad Brambach in the form of bath treatments and drinking cures and is supervised in accordance with the pharmaceutical law.

The ingredients dissolved in the healing water are particularly well absorbed into the body through the skin when bathing and through the gastrointestinal tract when drinking. Through these two large immune systems they develop their natural and gentle effect on muscles and joints, metabolism and organ functions. The absorption is particularly enhanced by the high natural carbon dioxide content.

Radon – effect in the body

The Bad Brambach healing springs have a special ingredient - radon. It is used therapeutically in the low dose range. The healing effects of the natural radioactive noble gas have been known for centuries. It is based on the decay of the noble gas in the body, releasing alpha radiation. The resulting high-energy particles allow the body to eliminate functional disorders. The metabolism and repair mechanism of the cells are activated, as well as inflammation and the stimulation of self-healing powers. An increased release of endorphins relieves pain. Natural pain relief increases the quality of life because the use of conventional painkillers and their side effects can be reduced. After a radon treatment, pain relief can last up to 9 months.

What is Radon?

Radon is one of the rarest natural noble gases that occurs everywhere in the earth's crust. Under normal conditions it is odorless and tasteless and cannot be perceived by the naked eye. When we talk about radon, we usually mean the most stable, naturally occurring isotope: radon-222.

What properties does radon have?

Radon has various effects on the human body. It has been used as a natural remedy and for therapeutic purposes in spas and healing tunnels for more than 100 years. In Bad Brambach it is present in increased concentrations due to the geological nature. The one located there Wettin source is the strongest source of radon in the world.

Radon has a very short physical half-life of 3,8 days, during which half of the gas already breaks down into its subsequent elements. This is why radon therapies can only be carried out near natural radon deposits. The human body excretes additional radon through natural processes, which significantly reduces its half-life. After just 20 to 30 minutes, the amount in the body is reduced to such an extent that it can no longer be detected.

Where is radon found?

Radon is found in the rocks and soil of our planet. From there it penetrates into the groundwater and the atmosphere. In this way, both springs and caves are created, the water or air of which is mixed with radon and is used for therapy.

Regions in which radon occurs increasingly are mainly the low mountain ranges made of granite rock. In Germany these include the Black Forest, the Bavarian Forest, the Fichtel Mountains and the Ore Mountains. In southern Germany the average concentration of radon is higher than in northern Germany. The Wettin spring in Vogtland is the strongest radon source in the world, which we make available to you in Bad Brambach in the form of various forms of therapy.

How is radon formed?

Radon is formed during the decay of uranium-238. The uranium used for energy production is uranium-235, a different subgroup of the element.

Is radon dangerous?

Radon is a weakly radioactive noble gas. However, we are constantly exposed to radioactivity in everyday life. Radon is only part of it. Its negative reputation arose because high concentrations of it were measured in residential buildings in some regions. However, the danger here is that people come into uncontrolled contact with the gas as it escapes unnoticed from the ground

However, if radon is controlled and applied specifically over a short period of time, as with radon therapy, it poses no danger. The therapeutic use cannot therefore be compared with the long-term exposure that politicians and the media warn about. However, in small doses, such as those used in therapeutic treatments, radon has even been shown to have a positive effect.

Is there a risk of radiation?

The additional radiation from a radon bath treatment is overall lower than that from a single x-ray. In Bad Brambach we work with a safe concentration. The positive benefits of radon in the context of therapeutic treatments are proven by both scientific studies and the experiences that participants in radon treatments have had. In small doses, the energy created by the radiation stimulates certain processes in the body. This has a positive effect on well-being.

Has the pain-relieving effect of radon been scientifically proven?

The studies carried out were so-called double-blind studies. This means that neither the doctors nor the experimental or control group knew who received the radon and who did not. Half of the therapies for patients with polyarthritis and ankylosing spondylitis were each supplemented with radon.

The groups whose bathing treatments and inhalations were mixed with radon had significantly fewer complaints. The therapies differed only in terms of radon; all other measures were the same. It is interesting that the improvement after therapy with radon lasted much longer, so that the patients had significantly less pain for up to 6 to 12 months.

This results in savings on medication, which has a positive effect on health. The side effects of strong medical products often make additional medication necessary. Painkillers can also have harmful effects on an already weakened body over a long period of time.

Overall, radon treatment has been used successfully for over 100 years. Over time and many applications of radon to patients, it has been observed that the therapy has also proven effective for other diseases. You can find out more about which complaints radon treatment is suitable for under “Which clinical pictures and complaints are treated with radon”.

If you would like to read about studies relating to radon, then the publication “Radon as a Remedy – Therapeutic Efficacy, Biological Mechanisms of Action and Comparative Risk Assessment” is a good choice. The authors are various doctors and scientists: Peter Deetjen, Albrecht Falkenbach, Dietrich Harder, Hans Jöckel, Alexander Kaul and Henning von Philipsborn. The book was published in 2005 by Dr. Kovač.

What is radon therapy?

During radon therapy, medicinal water containing radon is used for therapeutic purposes. It is supplied to the body in various dosage forms in health resorts such as Bad Brambach and acts as a stimulus that can trigger the body's own healing processes. It can relieve chronic pain, stimulate cell renewal, gently stimulate the immune system and combat inflammation. In Bad Brambach we combine the individual dimensions of radon therapy so that they are tailored to your individual needs.

How does radon affect the body?

In all 4 dimensions of radon therapy (Bathing-drinking-inhaling-rinsing) absorb radon. It enters your bloodstream via the lungs, skin, and gastrointestinal tract and spreads throughout the body, where it continually breaks down. The different forms of application are coordinated according to needs and ensure even more efficient therapeutic success.
