Gentle relaxation in a caldarium:
mild heat, great effects

A caldarium is a ceramic-tiled room in which the walls, benches, and floor are heated by a warm air heating system called “hypocaust”. The temperature is usually between 40 and 50 degrees Celsius, and the humidity – in contrast to the tepidarium – is almost 100 percent, which creates a hot and humid room climate. A visit to the caldarium is a great way to prepare for a session in a hot or dry sauna, such as a Finnish sauna. It can also be used as a gentle sauna alternative for older people, children, and people who cannot visit high-temperature saunas for health reasons. A session in the calidum should last 15 to 20 minutes and be followed by rest period of 20 to 30 minutes. For positive long-term effects, two or three caldarium visits per week are recommended.

Regular sessions in the caldarium have a whole host of positive effects. They stimulate circulation, relax the muscles, and eliminate metabolic waste products. Additionally, the immune system is strenghtend and the body detoxified. The gentle warmth of the caldarium also provides relief for aching limbs and joints. Herbal mixtures and essential oils such as lavender, mint, eucalyptus, or camomile can be added to the caldarium to liberate the airways and cleanse the upper respiratory tract. Thanks to the low temperatures, the caldarium can also be visited by people suffering from cardiovascular diseases.
