I have an O2 detox machine and it works wonderfully for my clients.
The machine emits positive and negative ions into the water, which re-balance the energy (chi) in the body. As a result you feel more energised and relaxed and sleep really well at night. I treat lots of clients with the hydra detox and they all notice improvements in all sorts ways.
I can only give a limited explanation, but I'm sure if you contact hydra detox http://www.o2detox.com they will explain it more for you.
