PROBLEM TO BE SOLVED: To be able to obtain, from day to day, an effect similar to a thoron hot spring by means of a bath mat 1.SOLUTION: When a bath mat 1 sinks in a bathtub filled with hot water, thoron (energy emitted from thorium element) is generated in the bath mat 1 from monazite powder kneaded in a silicone rubber having gas permeability and elasticity. From the silicone rubber, the thoron is mixed with hot water in the bathtub and is brought into contact with a user who has entered inside the bathtub. As a result, the bath mat is useful for promoting the user's health. In the silicone rubber having extremely high gas permeability, there is an increased amount of the thoron mixed in the hot water through the silicone rubber in the bathtub, so that promotion of health can be more expected compared to other rubbers. |
