My sister recommended Wim Hoff. I'll scope it out. I had been considering buying an o2 concentrator since 2020 and I do have some voice/breath training and have found some exercises related to that that aren't dissimilar from Wim Hoff show some reduction in symptoms. Honestly, I feel very lucky to be as functional as I am. I do worry about how medical and political systems are responding to COVID and long COVID, but…
There is no proven health benefit to using an oxygen concentrator for patients without lung disease (such as emphysema). The limiting factor in delivering oxygen to tissues is hemoglobin, not inhaled PPO2. Extended exposure to elevated PPO2 can cause oxidative damage to lungs and nerves, especially above about 0.5 bar, so you don't necessarily want to use it unless you need it.
Thank so so much for this. Very useful information.
