You've been feeling tired lately, and you don't feel refreshed even after sleeping... You want to relax in a hot spring because you haven't been able to rest properly... For those people!! When you think of a rock bath in a shop or salon, you imagine it's very large and can't be placed at home. If you've experienced it once, you'll know that the feeling of refreshment after leaving the rock bath is exceptional. Don't you feel like various things have come out with your sweat? It feels really good. The rock bath "Goyururito" was developed so that you can easily enjoy that refreshing feeling at home. You will use it together with the "sleeping bag" that is delivered with the product. Moreover, this "Goyururito" is not just a rock bath... It is a rock bath that is as close as possible to the rock bath of the famous "Tamagawa Onsen"!! ◎ "Hormesis effect" by low-dose radiation Substances such as radium (radioactive substances) have an inhibitory effect on the human body in large quantities, but it is said that they provide a balanced and beneficial stimulus to the human body in small amounts. When the human body ingests a small amount of radiation, the cells are stimulated in a balanced and beneficial way, and new cells are created one after another. These effects were named "Hormesis effect" by Dr. T. D. Luckey.
