What is a caldarium?
The caldarium, also called a calidarium, is a part of classic Roman thermal bath. In a caldarium, the walls, floors and benches are heated by floor heating (warm-air heating). The air humidity is almost 100 %, while the air temperature is below the wall temperature. This ensures a warm, humid climate. A caldarium is often used as preparation for a highly tempered sauna, or by people who are unable to visit a hotter sauna because of circulatory issues. Children getting used to the sauna lifestyle can also use the caldarium.
Benefits and Applications of the Caldarium
The intensive heat in a caldarium penetrates deep into your body and boosts your circulation. Some people refer to it as a “fever sweat bath”. Tense muscles relax, your skin becomes smoother, stress seems to melt away, and sore joints and limbs are soothed. Perfect conditions, in other words, for those who want to avoid excessive stress, or relax deeply. The temperature can be set to your individual preference.
To relax, it should be set within the body temperature range – between 30° and 40°C. To sweat or detoxify, it should be set to 50° to 60 °C. Humidity is low, at around 20%, and the air itself is not as hot as the walls. This means you can stay inside for longer.
