◎ The same energy as Hokutolite (Hokuto Stone) "Go Yururito" has been able to get as close as possible to the "Hokutolite" of Tamagawa Onsen. Low-dose radiation, far infrared rays, negative ions, and geothermal heat, all said to boost immunity. Everything is reproduced. The geothermal heat of the rock bath (about 50°C) is applied with the technology of a thermal therapy device. ◎ "Hormesis effect" by low-dose radiation Substances such as radium (radioactive substances) have an inhibitory effect on the human body in large quantities, but in small amounts, they are said to provide a balanced and beneficial stimulus to the human body. When the human body absorbs a small amount of radiation, cells are stimulated in a balanced and beneficial way, and new cells are produced one after another. These effects were named "Hormesis effect" by Dr. T.D. Luckey. ◎ Far infrared ray effect In Oriental medicine, warming the body is said to be very beneficial. The rock bath of Tamagawa Onsen is one example, but the Tamagawa ceramic of "Go Yururito" has been measured to have the world's highest far-infrared radiation rate. Warm your body to the core with far infrared rays. ◎ Negative ions Negative ions, as everyone knows. Relax your mind and body, and refresh your daily stress!
