An unusual sauna named "Sauna Mom" has opened in Tokyo (in the Roppongi area), offering its visitors a 120-minute session of symbolic "rebirth" and immersion in the atmosphere of the mother's womb. A sauna space at a temperature of about 85°C and 40% humidity, dim red light and a sound in the shape of a heartbeat. A cool bathtub (temperature 15 degrees Celsius, depth 80 cm), whose visual design is reminiscent of the blurred vision of a newborn, and a special shower corner with warm water on three sides that allows you to rest your head on a structure that simulates your knees. The centerpiece of a maternal care session is an ergonomic C-shaped sofa that supports the body in the fetal position, gently sways and creates a hug effect. At the end of the ceremony, everyone who completed the ceremony receives an official certificate of "rebirth". The cost is 8,500 yen per person and up to 20,000 yen for a group of four (a project for a maximum of four guests per session).
