The most relaxed way to dive.

A low heart rate guarantees longer dives.

Those who learn to relax in the water can also transfer this knowledge to everyday life and other sports, such as scuba diving, swimming and other endurance sports.

In this 90-minute workshop, Nik explains the relaxation techniques, the breathing exercises and the mental techniques you need to hold your breath for a long time.

After a theory, breathing and relaxation sequence, we go into the water to awaken the body’s own relaxation mechanism – the diving reflex.

Duration approx. 90 minutes

Effects & Benefits

“Because I could simply glide through the water on my back, it was a very gentle and relaxing stretch. Especially since it is no longer possible for me to lie on my back outside the water, massages are unfortunately no longer possible at all. Aqua Relax was a totally great solution!”
– Lara, 34th week of pregnancy

Relaxation inspired by freediving

The desire to breathe for inner balance.

Discover the desire to breathe in the Keidel Therme – a unique relaxation course inspired by apnea diving. Combine breathing techniques, meditation & yoga in the warm thermal water for inner balance and more serenity.

Relaqua is a relaxation concept developed by trainer Nik Linder with its origins in freediving. In this extreme sport, experienced athletes dive in water depths of up to 130 meters with just one breath. In order to consume as little energy and oxygen as possible, the diver must be completely relaxed. To do this, the athletes use different techniques that lower the pulse and calm body and mind. The Atemlust course combines breathing techniques of apnea diving with elements of yoga, meditation and mindfulness. The aim is to learn mental skills, activate inner balance and thus meet the challenges of a demanding everyday life in a more balanced way.

In a world that is spinning faster and faster, it is important to consciously take time for yourself.

Our Aqua Relax offer at the Keidel Therme offers you exactly that: a soothing combination of gentle movement, mindfulness and relaxation – embedded in the calming atmosphere of our warm thermal water.


Gentle movement in the water – ideal for body and mind
The flowing, slow exercises in the water are particularly easy on the joints and at the same time promote mobility, blood circulation and general well-being. The combination of movement and conscious breathing helps to release tension and clear your head.

Particularly suitable for pregnant women
Aqua Relax is also a wonderful way for pregnant women to do something good for themselves and their bodies. The warm water relieves the joints and spine, while the gentle movements help to relieve tension and strengthen the muscles – without being overwhelmed. At the same time, the quiet atmosphere offers space for conscious connection with one’s own body and the unborn child.

Thermal water with natural healing power
The mineral-rich water of the Keidel Therme additionally supports the effect of the programme. It has an anti-inflammatory effect, promotes regeneration and gives a feeling of lightness and security.

A little break from everyday life
Whether after a hard day’s work or simply in between: Aqua Relax is your personal break from everyday life. The combination of water, exercise and silence is like a short holiday for body and soul – and without packing your suitcase.

Conclusion:
Aqua Relax is more than just a treatment – it’s an invitation to treat yourself. Whether you are pregnant, longing for relaxation or simply looking for a gentle form of exercise: Treat yourself to this soothing time-out in the water.


Aqua Relax as a form of therapy

The Aqua Relax method consists of three phases:

Phase 1 – Build trust
The first phase is all about building confidence in yourself and not being afraid of moving in the water. Through controlled breathing, you learn in the first phase to respond to the flow stimuli of the water.

Phase 2 – Balance control
Different postures and positions are trained and maintained via the torso. Exercises such as turning in the water or rotation exercises stabilize the musculoskeletal system.

Phase 3 – Body control
In the last phase, the focus is on independent movement in the water. Without aids and only through the water buoyancy, action in every situation in the water is learned.

Effect

Aqua Relax is a special form of body relaxation in the water that everyone can participate in. No previous knowledge is necessary for this. The guest floats on the surface of the water, largely relieved of his own body weight. In this way, he/she can enjoy the full attention and mindfulness of the practitioner.
