Hydrogen is detected in exhaled breath after drinking hydrogen water, and a similar phenomenon is observed in hydrogen bathing. This represents the state of hydrogen penetrating the skin and sufficiently filled inside the body, and the antioxidant effects of hydrogen that have been reported can be expected with it.
The benefits of taking a warm bath cannot be obtained by drinking hydrogen water. Besides, it has become evident that hydrogen bathing increases the benefits more than plain warm bath. Also, it was found that it increases skin elasticity and makes the hair shinier and smoother, and therefore, it is conceivable that taking a hydrogen bath in combination with drinking hydrogen water can increase the effectiveness.
