? This product is a convenient alternative to the very popular Tamagawa Onsen and Bad Gastein bedrock baths. As evidenced by the Bad Gastein mine, miners had the highest immunity, and it is said that the time spent in the mine is important. The negative ion capacity of 5000 ions/1cc has the power to easily penetrate the palm of your hand. When lying on the L-size bedrock bath mat, it will easily penetrate your skin. Even if you are not lying down, the super ions generated by the mat will enter your body when you breathe, providing a forest bathing experience! The mat is made by impregnating the mat with bedrock powder, so it may stain your clothes. Please use it with a bath towel or similar placed underneath. This will not affect its performance. There is also data from the Japan Food Research Laboratories confirming that it does not contain harmful cesium 134-137.
Enjoy a convenient forest bathing experience at home!
