Into a Whirlcare®, out of the blues

Do you feel dejected, constantly tired, listless and irritable and would like to be at home alone? If you’re lucky, you have your own oasis of well-being there and can enjoy moments of real pampering in a Whirlcare spa. The
fact that whirlpool baths can help us get rid of depressive moods has also been scientifically proven.

Be it winter blues or depressive disorder: The fact that people are usually in their worst moods in winter is often due to a lack of daylight. It is still dark when we go to work in the morning and already dark again when we come home. “This has an effect on the hormone balance,” explains Dr. med. Bertram Schädle Specialist in anesthesia, intensive care and preclinical emergency medicine. “When the days are short and dark, our body releases more melatonin. The sleep hormone regulates the body’s day-night rhythm, making us tired and sluggish.”

At the same time, the serotonin level reaches its lowest point in winter, which is not without consequences for our mental well-being: A lack of this “happiness hormone” can make us anxious, sad, miserable and dissatisfied, and even cause depression. According to Dr. Schädle, there are many other causes in addition to hormonal imbalances – regardless of the season: diseases, pain, long-term stress, misfortune, unresolved conflicts, etc.

“A bath in a Whirlcare spa can help to overcome your depressive mood. Immersing yourself in warm water stimulates the release of endorphins by the pituitary gland,” says the specialist in anesthesia, intensive care and preclinical emergency medicine. In addition to the relaxing effect on the body and mind, the body temperature also rises, which helps you to fall asleep. This promotes deeper sleep and reduces the consequences of fatigue.

The soul is the reflection of our health

The positive effect on mental well-being is proven by a study that was awarded the Holzschuh Prize for
Complementary Medicine in Baden-Baden in 2017 (Catharina Sadaghiani et al: “Efficacy of hyperthermal
baths in depression – results of a randomized, controlled study”). Dr. Bertram Schädle, specialist for
anaesthesia, intensive care and preclinical emergency medicine, points this out.

The study, which was carried out in a hot tub in a thermal bath, shows that 20 to 30-minute hyperthermal
baths at 40 degrees Celsius produce “a clinically significant improvement in depressive symptoms and
sleep quality” after just four applications. A significant superiority of the hyperthermal baths over a sham
treatment was proven, with the efficacy already present after two weeks or four applications.

The skinoxyform therapy in a Whirlcare spa can intensify this effect according to Dr. Schädle:
“Skinoxyform produces millions of microscopic oxygen bubbles. These form negative ions on the surface
of the water, the inhalation of which can lead to an increase in the serotonin level.” The extra portion of
oxygen can also have a positive effect on fine lines and wrinkles and improve the appearance of the skin.

And let’s face it: Don’t we automatically feel better when we feel beautiful and do something good for


Suffering from arthritis?
Improve your quality of life!

Arthritis is the most common of all joint diseases and is often associated with considerable pain and restricted movement. The clinical picture gradually worsens: Initially, the affected joints feel somehow stiff and tense. At first, pain is only felt under stress or after longer periods of rest, for example when getting up in the morning. But at some point, permanent discomfort, massive movement restrictions and the diagnosis: arthrosis follow.

“But with whirlpools and swim spas from Whirlcare, those affected can regain a bit of quality of life,” says Schädle.

According to the German Arthrosis Aid Association (Deutsche Arthrose-Hilfe e.V.), around five million people in Germany alone suffer from arthrosis – and the number is rising. In this degenerative joint disease, the protective cartilage layer continues to wear away until bony changes and deformations finally occur.


When even everyday movements hurt and the quality of life declines with diminishing mobility, the end result is often the use of an artificial joint.

„Unfortunately, conventional medicine usually only offers symptom-oriented treatment methods such as painkillers. These are justifiably viewed very critically by patients, among other things because of their high potential for side effects,” Dr. Schädle knows from experience. But there are definitely gentler methods to improve the well-being of those affected.

Many arthritis patients know this: in wet and cold weather, the symptoms get worse. Warmth, on the other hand, “provides a feeling of well-being, alleviates pain and promotes healing”, as stated in Rule No. 2 of the German Arthritis Foundation . “Whirlcare has used this knowledge, which has already been used successfully by ancient doctors, in the development of its hot tubs and swim spas and has expanded
it to include numerous hydrotherapeutic functions,” emphasises the doctor, naming the following points:

  • Intensive underwater massages that reach almost all body zones.
  • Hydrotherapy jets that are positioned to target muscular reaction points and problem areas.
  • Anatomically correct seating and lying surfaces for maximum relaxation
  • Stronger buoyancy compared to other hot tubs, relieving the strain on tendons, ligaments and joints.

“The targeted stimulation of blood circulation in a Whirlcare can contribute to relieving pain and tension,” confirms Schädle. While cooling would be required for acutely inflamed joints, the combination of warmth, hydromassages and the buoyancy of the water that is gentle on the joints creates ideal conditions in the chronic stage to reduce arthritis pain and joint stiffness. Depending on the severity of
the arthritis, it may even be possible to dispense with anti-inflammatory or analgesic drugs entirely or reduce their quantity. “In any case, the patient experiences a significant improvement in quality of life,” emphasises the doctor.

Dr. Bertram Schädle from Tübingen, who also specialises in the treatment of acute and chronic pain, refers to a study from 2013 28, which deals with the effect of hydrotherapy on knee and hip osteoarthritis and demonstrates the positive effects. “The aim of this pilot study was to determine the effects of hydrotherapy in comparison with conventional physiotherapy. It was found that the pain intensity of the affected joints in the hydrotherapy group decreased the most in comparison with the two control groups. The flexibility of the joints also improved”, quotes the specialist in anaesthesia, intensive care and preclinical emergency medicine.

Schädle points out that the regular use of hot tubs is also recommended by the US Arthritis Foundation. According to the Foundation, whirlpool baths could support the strength and flexibility of the joints and even protect them from further damage: “Heat, massage and buoyancy improve the well-being of arthritis patients. The buoyancy of the water reduces the pressure on the joints and promotes mobility,”
the Foundation says.

The less pain you have, the more you move. And moderate movement is the be-all and end-all for arthritis: it stimulates the metabolism in the joints, so the joint cartilage is better supplied with nutrients. According to Dr. Schädle, sports such as swimming, aqua-cycling or aqua-aerobics are particularly suitable for this purpose. Due to the water resistance, this training is much more effective than movement on land; at the same time, ligaments, tendons and joints are spared due to the natural
buoyancy of the water.

When your back is hurting...

Sometimes it comes out of the blue, that stabbing pain in the back.
But sometimes it is also a creeping process: you feel how the muscles
gradually become tense, how every movement feels like
fighting against an invisible resistance until suddenly nothing works any more:
The neck is completely tense and every time we get up,
we try to avoid the imaginary blade that seems to drill into our spine.

80 percent of Germans suffer from back pain at least once in their lives. It is the number
one public symptom and the most common cause of sick leave. "It is primarily the 150 muscles
close to the spine that decide whether the back hurts or not," says the Aktion Gesunder Rücken
e.V. (Campaign for Healthier Backs) in ist homepage. „The main triggers for muscle hardening
are poor posture, one-sided strain, lack of exercise or even long-term stress; in addition to
stretching exercises, warmth and massages can also provide relief – applications which
a hydromassage in a Whirlcare combine optimally," says Dr. Schädle.


For thousands of years, people have been bathing in hot springs to relieve their pain or increase their well-being. The brochure “Natural healing procedures – safe and effective methods of natural medicine” lists, among other things, promotion of blood circulation, reflexive muscle relaxation and numerous possibilities of the pain therapy as acute effects of the warming stimulus by hydrotherapy (publisher: European Health Centre for Natural Remedies – Sebastian Kneipp Institut GmbH).

Doctor Schädle points out that the hydromassage in a Whirlcare spa would specifically promote blood circulation. This can help relieve tension and pain.
At the same time, the heat of the water would be transferred to the surface of the skin by direct heat conduction, creating a feeling of well-being. In addition, the buoyancy of the water would relieve joints, ligaments and tendons and create a feeling of (almost) weightlessness: You feel like you are floating.

Hydromassages as stress-busters
There are times when we just can't relax. One appointment follows the next, we are lagging behind schedule and still try to get everything together. We are simply passengers on the motorway of our lives and feel overwhelmed, exhausted and stressed. How nice it would be now to just switch off and forget the world around us! There is a reason why wellness holidays that promise us a break from everyday life are in vogue. However, the recuperative effect often falls short of expectations: overcrowded swimming pools, the loud sauna infusion party next door and the endless wait for a free space in the hot tub are by no means conducive to relaxation. A dip in a Whirlcare – on your own terrace and in familiar surroundings – is like a short holiday that simply bubbles away stress and tension.


What is perceived as stress and how we deal with it varies greatly from person to person. “However, it is problematic when stress becomes a permanent condition and there are no more relaxation phases”, says Dr. Schädle. Stress could then trigger serious symptoms, such as high blood pressure or tachycardia, headaches, neck and back pain, sleep disorders, depression and much more. The close connection between body and soul can also be seen in numerous idioms, e.g. when something is “a pain in the neck”, “resting on our shoulders” or “makes you sick”.

According to a stress study by the health fund Techniker Krankenkasse, more than 60 percent of Germans feel stressed, almost a quarter of them even feeling stressed frequently. Conscious down times through sport or
relaxation can help us to cope better with the challenges of everyday life and to find our inner balance.

“There are studies that show that the nervous system reacts to warm water in the same way as it reacts to meditation or other relaxed states,” explains Dr. Bertram Schädle from Tübingen, a specialist in anaesthesiology, intensive and preclinical emergency medicine. For example, Dr. Bruce Becker, a doctor and research professor at Washington State University, found that the sympathetic nervous system, the activity of which increases with stress, and the parasympathetic nervous system, which helps the body to rest, were rebalanced when lying in warm water. Massages also reduced stress hormones and promoted the release of endorphins as natural mood enhancers and painkillers.

Anyone who enjoys a massage or a hot bath to relax will benefit from a Whirlcare several times over: “The combination of intensive massages, warm water and numerous wellness features results in holistic relaxation that
helps us to reduce stress and recharge our batteries,” confirms Dr. Schädle: “As long as important anatomical considerations are taken into account and the jets are in the correct position, as is the case with Whirlcare, hydromassages are real stress-busters.”


Benefit from the power of colours

Coloured light not only looks beautiful, it also affects the psyche. Colour light therapy is based on the fact that each colour has its own wave spectrum and thus a specific effect: stimulating or soothing, encouraging or balancing. Idiomatically, this is clear to everyone: You might be a yellow-bellied coward, or quickly see red, until everything is in the green again. You may be feeling blue or seeing life through rose-tinted glasses. In alternative medicine, colour light therapy is often used to alleviate mental and psychosomatic complaints. It is also used to stimulate or harmonise body functions and to eliminate disturbances in energy flows. Whirlcare tubs with colour light therapy have different LED light points that can sit above or below the waterline. Using the colours red, yellow, green and blue, shades of different wavelengths can be mixed at the push of a button to create different moods.



Red is a powerful colour that can have a stimulating and exciting effect, and can also cause aggression in too high a „dosage“. Of course, red also stands for love and, at the same time, for passion, warmth and sexuality. In colour therapy, red is used against tiredness and to increase activity. Red has a stimulating effect on circulation and the metabolism.


Blue is associated with sky and water. It has a calming and cooling effect. The colour blue can help us escape from everyday life and satisfy our longing for peace. It should also relieve muscle tension and migraine.


Green symbolises balance and harmony. Green is said to have a calming, nerve-strengthening, and inspiring effect and can therefore be used, for example, for headaches, inflammation, nervousness or sleep disorders.


Yellow represents a bright colour, which is perceived as encouraging, revitalizing and liberating. It is supposed to support the mind, help with gastrointestinal disorders, and strengthen the nervous system.


Orange stands for joy, activity, and life affirmation, and is considered as a rejuvenating force in the case of physical or mental exhaustion. The colour not only stimulates the psyche but, according to colour therapy, also has a positive effect on the metabolism, immune system, and cell tissue.


Violet is used against desperation and hopelessness, as well as for cleansing and purification. Violet is considered a healing colour for the mind, has a strong meditative effect, and is supposed to promote mental balance.

Fragrances stimulate the body and mind

The smell of a freshly mown meadow that reminds us of carefree summer evenings; the lavender soap from your holiday in southern France, or the scent of a lilac bush just like once upon a time in grandma’s garden: There’s no question about it, smells arouse memories and trigger emotions. This happens because they work directly on the emotional limbic system in the brain. In aromatherapy, a branch of phytotherapy (herbal medicine), we take advantage of this: Distinct scents stimulate the body, mind and soul, and can influence your mood or physical condition. The knowledge of the power of essential oils is ancient: the old Egyptians were already using plant essences for embalming, in cosmetics, for massage, and for health. The close connection between fragrances and emotions has also been reflected in numerous phrases, for example, when somebody „has a nose for something“.


Aromatherapy is considered a beneficial holistic adjunctive therapy. The corresponding fragrances are sprayed into and used in the whirlpool tub’s water, which can have positive effects, especially in relation to mental and spiritual imbalances. Only special
fragrances suitable for whirlpool tubs may be used, otherwise the hydrojets and the pipe system may be damaged.

The effect can range from calming and antispasmodic, to mood-enhancing and concentration-promoting, to analgesic. Depending on your mood and emotional state, you can improve your well-being with the right choice of the aroma.

The magic of music

It can spur us to peak performance, make us feel melancholic, or happy, and help us relax: music. In movies, it gives us goose bumps; our playlist motivates us during sport; and if you want to relax after a stressful day, simply close your eyes and listen to your favourite songs – balm for the ears, mind, and soul.
The fact that music touches us so intensely is due to its effect on the brain areas that are responsible for emotions. Strongly rhythmic pieces tend to be stimulating and invigorating, while gentle melodies calm and relax us. Music not only influences our mood, but also our physical well-being: Heart rate and pulse, blood pressure and rhythm, and even the sensation of pain can change – findings taken advantage of by doctors and therapists.


For example, a double-blind study at the University of Leipzig Medical Faculty found that
„(…) the activity of amygdala, hypothalamus, and brainstem nuclei is attenuated by
positive music, reducing anxiety, subjectively experienced stress, and even stress
hormones.“ The findings of Japanese researcher Dr. Masaru Emoto are also astounding:
He found that different styles of music have very different effects on the molecular
structure of water.

Let yourself be enchanted by the magic of music – the sound system in your Whirlcare
will help you to relax and enjoy your personal sound therapy. Systems with subwoofers,
which transmit the vibrations to the water and make them perceptible below the
surface, are particularly pleasing. The music to be played can be controlled via Bluetooth,
USB or wireless remote.

With our Smart Spa, this can even be done by voice: It combines voice input, WiFi
functionality, and powerful speakers, with the integration of Amazon’s Alexa. This means
that, during your whirlpool bath experience, you can even enjoy music streaming
services like Spotify, Amazon Music and many more.
A wellness experience for all senses offers relaxation music, which is suitable for
meditating, reminiscent of holidays or inspiring by sounds of the Far East.

If you could turn back time…

Looking young has nothing to do with age. Skinoxyform® renews and protects your skin, our biggest organ, against external influences, such as air pollution, pathogens, heat and cold.

The skin is also a reflection of our soul: Stress, smoking, environmental toxins and an unhealthy lifestyle leave their marks. The skin looks tired, pale and flabby.

Skinoxyform® Oxygen Therapy helps your skin to store nutrients, absorb medications, and excrete toxins and metabolites.


[ Skin ;

Oxy gen;

to re form ]

Millions of tiny oxygen bubbles caress your body as you lie relaxed in your Whirlcare. The micro-bubbles penetrate deep into the skin, eliminate
impurities, and provide natural moisture. The production of collagen, responsible for strength, structure and firmness, is boosted. You feel
refreshed and balanced.

Skinoxyform, Whirlcare’s innovative hydro-oxygen application, increases the oxygen content in the water by more than 70 percent. This stimulates the metabolism, improves cell growth and the deep hydration of the skin, even reducing lines and wrinkles.

The microscopic oxygen bubbles, which give the whirlpool bath water a milky-white appearance, are generated by a special pump and injected into the water.

For comparison:
A classic air bubble generated by an airjet is about
50 to 100 times larger. Thanks to their small size, the
bubbles burst in the water and not on the surface and
keep the heat evenly in the whirlpool tub. This so-called
„sauna effect“ is known to contribute to strengthening
the heart and circulation. In addition, our Skinoxyform
application can neutralise the skin-ageing free radicals
that increase serotonin levels, improving sleep quality
and well-being.

What Skinoxyform can do for you
  • Tiny oxygen bubbles allow for natural deep cleansing and hydration
  • The sauna effect ensures even heat and can strengthen circulation
  • Inhaling the negative ions can lead to deeper relaxation and increased serotonin levels
  • Provides oxygen for better skin metabolism
  • May have a positive effect on crow’s feet as well as fine lines and wrinkles
  • Promotes cell growth of the skin, can reduce scars and skin defects
  • Can relieve the symptoms of eczema
  • Free radicals that cause skin ageing can be neutralised
The happiness hormone

Inhaling the negative ions can lead to deeper relaxation and increased serotonin levels. Serotonin controls many different processes. In the central nervous system, for example, serotonin is an important messenger substance that, inter alia, has an effect on the following body functions:

  • body temperature
  • appetite
  • emotions
  • central reward system
  • mood and motivation
  • consciousness and sleep-wake-rhythm
  • pain rating

Serotonin gives you a good mood, restful sleep and increases your drive. It not only affects the psyche but also regulates body temperature and supports digestion. As a neurotransmitter it passes on stimuli that trigger heartbeat, muscle movement and thinking processes.
