Basics

Basics

What happens with cryotherapy / cold therapy?

In order to keep its core body temperature at 37 °C, the body boosts its metabolism. The skin surface temperature drops by approx. 15 Kelvin. The body activates its protective mechanism and produces heat, and the release of endorphins creates a feeling of happiness. This also provides energy, focus and promotes calorie consumption. The body's own defence system is activated and detoxification is stimulated. Blood flow and the production of collagen increases and the production of new cells is stimulated. The body releases hormones and enzymes into the bloodstream to aid regeneration.

Basics

Is a cold chamber or a cryosauna used in the cryoduct?

For whole-body cryotherapy, we use an electricity-driven high-performance cold chamber (most powerful cold chambers from Art of Cryo), i.e., no cryosauna or a nitrogen-operated system. In the cabin, the entire body is exposed to very dry air with a temperature of -110 °C. In this way, it is safe to expose the entire body including the head to the extremely low temperature. An electrically cooled cryochamber has the additional advantage that the cold is evenly distributed over the body. Nitrogen quickly sinks to the floor of the cabin and ensures that the upper body is less cold than the lower body.

Basics

Kryotherapie, Cryotherapie or Cryotherapy?

The meaning is the same. «Kryotherapie» is just the correct variant in German. However, as more and more terms from foreign languages are being incorporated into German, «cryotherapy» or «cryotherapie» is also increasingly found in German-written texts.

Application

Application

How long does the cold application last?

The application time is calculated individually to the second for each user by the RemediCool software based on a detailed anamnesis. The time of application is influenced by gender, age, body size, weight, skin type and the area of application. Basically, the application times are 3:00 minutes.

Application

How do you dress in the cold room?

During the application, you wear short sportswear or swimwear (important: women's bikini or bra, but no bathing suit!) Sensitive parts of the body are protected with a face mask, earmuffs, gloves, socks and chamber shoes. We provide everything.

Application

How often can I repeat the application?

Basically, you can go into the cold chamber every day. The recommended repetition of the application is calculated individually by the RemediCool software together with the optimal application time for each user.

Safety

Safety

How safe is it to use the cold?

Cryotherapy has been used safely for over 30 years. Due to our close cooperation with doctors and specialists, we can fall back on a team of medical experts. Our employees in the Cryodukt are certified cryo operators for whole-body cryotherapy and are therefore well trained to be at your side with any questions you may have.

Safety

Are there any risks in using it?

No, we will discuss everything you need to know about the application in advance and give you advice in detail. Due to the individual application time, the use of the RemediCool software, as well as the special training of our employees, we can offer safe and successful refrigeration applications. Blood pressure may rise a little, but this is only temporary and normal.

First visit

First visit

How does the first visit work?

With the certified software from RemediCool, we first determine the general applicability of a cold therapy for you. If applicable, the software determines your individual application time based on your personal physiological data (such as skin type, fitness level, gender, and BMI). Combined with your thermal perception before and during your first application at -110 °C, we can calculate your personal ideal application time taking your goals into account. Your cold experience begins with a continuous cold adjustment in the two anterooms at -10 °C and -60 °C, and the actual application takes place at -110 °C. A trained full-body cold coach will accompany you throughout the application. Of course, the application can be interrupted at any time and the chamber can be exited.

First visit

Do I have to shower before or after the session?

Showering before treatment is not required. Dry skin is even better! Your skin will stay dry even during the session. Showering is also not required after the session.

Effects & side-effects

Effects & side-effects

Can I catch a cold from cryotherapy?

You can't catch a cold during treatment. However, your immune system is stimulated. Most likely, you will find that you are generally much less susceptible to colds.

Effects & side-effects

What are the possible side effects after treatment?

Energy boost or fatigue (from detox). Headache (due to detox).

HBOT

HBOT

What is HBOT and how does it work?

In hyperbaric oxygen therapy you breathe up to 97 % pure oxygen under slightly elevated pressure inside a pressure chamber. This dissolves oxygen directly in the blood plasma — independent of red blood cells — reaching tissue areas that are normally poorly supplied. It promotes cell regeneration, reduces inflammation and boosts cognitive and physical performance.

HBOT

How long does a session last?

An HBOT session typically lasts 85 minutes.

HBOT

What should I keep in mind before a session?

Come well-rested and well-hydrated. If you smoke, avoid cigarettes at least 2 hours before the session — nicotine constricts blood vessels and noticeably reduces the therapy's effectiveness. Alcohol on the same day is also not recommended.

HBOT

Who is HBOT suitable for?

HBOT is suitable for competitive athletes in recovery, people with exhaustion or long-Covid symptoms, those with chronic inflammation, and post-operatively for faster wound healing.

IHHT

IHHT

What is IHHT?

IHHT is cell training where you alternately breathe oxygen-depleted and oxygen-enriched air — comfortably lying down, without physical exertion. The intervals train the mitochondria, the "powerhouses" of your cells, and improve oxygen utilisation at the cellular level. The result: more energy, better endurance, strengthened cell health.

IHHT

How does a session work?

You lie relaxed on a lounger and breathe alternating hypoxic (oxygen-depleted) and hyperoxic (oxygen-enriched) air through a mask. A session lasts about 40–60 minutes. The intervals are individually tailored to you.

IHHT

What should I keep in mind before a session?

Please do not eat for 2 hours before the session — a full stomach can make the training uncomfortable. Avoid intense exercise at least 4 hours beforehand so your body is not already stressed and can respond optimally to the intervals.

IHHT

How often should I do IHHT?

For a noticeable effect we recommend 10–15 sessions, ideally 2–3 times per week. Many of our guests integrate IHHT as a regular longevity routine.

IHHT

Who is IHHT particularly suitable for?

For people with declining performance, chronic exhaustion or limited resilience — but also for athletes who want to specifically improve their aerobic capacity. IHHT is gentle on the joints, passive and suitable for almost any age.

Flow

Flow

What is Flow Compression Therapy?

Flow is a mechanical compression and lymphatic drainage therapy where cuffs on the legs, hips or arms apply rhythmic pressure. This promotes lymph flow, supports circulation and accelerates recovery — similar to a professional sports massage, but more precise and deeper.

Flow

How long does a session last and what does it feel like?

A session lasts about 15 minutes. You lie comfortably while the cuffs inflate and deflate in waves. The sensation is pleasant — most guests find it relaxing and almost drift off to sleep.

Flow

When is Flow particularly useful?

After intense training for faster muscle recovery, for swollen or heavy legs, water retention, or simply as a weekly recovery ritual. Flow is also especially effective in combination with cryotherapy or HBOT.

Flow

Is there anything I should keep in mind beforehand?

No special preparation needed. Wear comfortable, not-too-tight clothing. If you have active inflammation, deep vein thrombosis or open wounds in the treatment area, please speak to our team first.

Flow

Can I use Flow regularly?

Yes, Flow can be used several times a week without any issues. Many guests combine it with other treatments at Cryodukt as a fixed part of their recovery routine.
