Little ABC for your spa-break questions ...

In their treatment discriptions, wellness hotels often use technical terms, which are hard to understand for potential guests. We have therefore collected and defined the most relevant terms in our small wellness ABC. A tip: Our wellness dictionary also supports word requests. You don't need to know the exact wording.


Caldarium: What is it?

The Caldarium is a ceramic-tiled warming room with a temperature of 40-50° C. The mild radiant heat from the heated walls, benches and floor warms the entire room, which is heated by hypocausts, i.e. old Roman hot-air heating. In addition, Caldarien usually has several basins and bathtubs, in which guests can enjoy baths in 40 °C to 50 °C warm water. The air humidity is - in contrast to the tepidarium - very high and is almost 100 percent. The climate in the caldarium is therefore warm and humid. Scented essences often pamper the respiratory system during a stay in the caldarium. Essential oils and herbal mixtures such as lavender, eucalyptus or camomile are popular. The recommended length of stay is 15-20 minutes, followed by a 20-30 minute rest period. 

How does a break in the caldarium work?

A break in the caldarium has many beneficial effects on the organism. These include:

  • Stimulation of the blood circulation
  • Reduction of metabolic waste products
  • Mobilisation of the immune system
  • Detoxification and purification of the body
  • Reduction of harmful environmental influences
  • stimulation of the heart activity 
  • Activation of the circuit
  • Reduction of feelings of stress
  • Relaxation of the musculature

In order to feel the positive effects of caldarium in the long term, two to three visits per week of 20 to 30 minutes are recommended.

For whom is a break in the caldarium useful?

Visits to the caldarium are popular for preparing for sauna sessions. They are also suitable for older people and children, as well as for people with circulation problems.

History of the Caldrium

Caldarium comes from the Latin language and means something like "warm" or "hot". The caldarium was already an integral part of classical Roman baths in ancient times. These all had the same structure, based on an identical sequence of rooms. For example, the caldarium with hot water basins was the first room in which people stayed when visiting a thermal bath. The floor temperature was often over 50°C, which is why those present usually wore clogs. In addition, many visitors enjoyed baths with a temperature of around 40°C while enjoying the view from the large windows. The windows also provided further heating of the room.
