Hydrogen doesn’t cause toxicity in our bodies but I’m fairly sure oxygen does quite readily. Water does as well. Many people experience mild forms of water toxicity, and although it’s rare, it can be fatal too. Oxygen is pretty dangerous stuff, you really do need to moderate intake and allow buffers in your body from having too much of it.
