Laser doppler imaging of cutaneous blood flow in the foot immersed for foot bathing made it possible to visualize the two-dimensional spatial variation of the perfusion while being not only noninvasive but also non-touch. Therefore, it reduced the risk of influence on skin perfusion mechanically, being di#erent from the method used so far. This method revealed that the cutaneous blood flows by CO, water foot bathing were increased from nearly two to four times in comparison with those by tap water foot bathing. In Japan, natural CO, spring waters are rare. However, we proposed that development of a co-generation system with hydrogen cell evolved exothermic heat, and hydrogen and carbon dioxide gases makes it possible to prepare and perform easily artificial CO, bathing therapy, with a reductive characteristic analogous to natural spring water, at home and elsewhere.
