Professor Shigeo Ota (Nippon Medical School) has confirmed that hydrogen circulates throughout the body within 5 to 10 minutes after a hydrogen bath. This is evident from the excretion of excess hydrogen in exhaled breath. During a hydrogen bath, hydrogen is absorbed not only through the skin but also inhaled from the hydrogen escaping into the air from the water surface, allowing it to reach cells throughout the body. 
Therefore, it is said that several times more hydrogen can be absorbed compared to drinking hydrogen water. Professor Ota himself recorded a drop in blood pressure when he took a hydrogen bath. This is thought to occur because blood vessels dilate, improving blood flow. While drinking hydrogen water takes time to feel its effects, “hydrogen bathing” allows you to experience benefits in just 5 to 10 minutes.
The advantage of the hydrogen bath is that it continuously generates a large amount of hydrogen gas for about three hours. While the solubility is low without agitation, it produces an incredible volume of hydrogen gas regardless.
You can use the Ritalife and hydrogen bath together. It's simple: just place the hydrogen-generating agent in the dedicated case and put it in the bath. You can even take it on trips. It's incredibly convenient and an excellent product anyone can easily incorporate into their routine.
