Iyashi Dome: the original Japanese infrared sauna experience

Iyashi is a Japanese word which can mean relief, healing and cure depending on the context
What is Iyashi Dome?

Iyashi is a Japanese word which carries the notion of wellness. It has, however, a number of other meanings depending on context – including relief, healing and cure. The word Dôme has been added to reflect the technology. The brand itself was created in 2004 and it was the first company on the market – hence Iyashi Dôme became the generic term for “japanese sauna” (the combination of dry heat and Japanese technology). The technology has been inspired by the ancient Suna Ryoho practice, which originates from the Ibuzuki beach in the south of Japan. For centuries, people there have been burying themselves in the hot sand – which has been warmed up by the sun and the underground hot springs – to induce sweating. As the sand on the beach is volcanic, it emits infrared which is perfect for the purpose of sweating.

How does it work?

Iyashi Dôme Sessions take 30 minutes. Guests strip and then spend 15 minutes lying on their front and 15 minutes on their back. The first 15 minutes feels like a sun bathing session and is very relaxing – many people fall asleep during the process. We describe the second 15 minutes as a “sport session”, as users sweat intensely during it. It is estimated that each 30 minute session is the equivalent of a 20km run, burning up to 600 kcals and sweating up to 1,200ml.

What health benefits does Iyashi Dôme offer users?

It has shown proven results in a number of areas – it helps people to detox and slim down and also has anti-ageing benefits. It also works in a sports environment, aiding preparation and recovery. To prove the effects, we have invested in clinical studies which clearly outline the benefits. A clinical trial undertaken in Switzerland, for example, showed that users who undertook two sessions a week achieved an average weight loss of 4kgs. The analysis also showed that, through sweating, Iyashi Dôme can help rid the body of toxic heavy metals – including strontium, barium, nickel, lead, chromium, arsenic and cadmium.

How can installing an Iyashi Dome benefit spas?

By adding a new customer offer and increasing business. It is a “hands free” device, so therapists can safely leave a customer while undertaking other tasks.

What is the recommended set-up at a spa?

Iyashi Dôme devices are 225cm long and 90cm wide, so they fit in most spaces. We recommend a room of 10-12sq m. A shower isn’t necessary. Some spas locate Iyashi Dôme in a separate room and others in rooms with massage tables in order to create signature treatments.
