I hired a soft chamber and used it for the recommended period. Whilst using the chamber I noticed an improvement in fatigue and muscle joint pain. I also enjoyed the time out it gave me and although I thought it would be claustrophobic, it really was lovely once I got in. Unfortunately the results were short lived but if budget allowed, I would add this as a tool for an extra boost. However I am sure that it did significantly help me with the Covid-esque symptoms of cold, running nose, blocked sinus, blocked throat which I couldn't budge for years.

Did 10 sessions. Felt slightly less brain fog while in the chamber, but effects did not last. Too expensive and energy consuming getting to facility to continue. Did cause some ear pain my first session, which was mitigated by them raising the pressure more slowly.

Loved this treatment. Was a 3 month commitment but completely resolved short term memory issues and greatly improved fatigue and stamina. For the first time in 4 years I could dance at weddings (3 of them in 6 months!) Unfortunately circumstances in my life pushed me far past my new and expanded limits, and I lost the gains. But confident if I had been able to control pacing, I would have continued to improve.

Did the normal protocol of 2.0 ATMs for 45 sessions. And had no effect on my long COVID symptoms.

I didn’t notice any effect with the remaining 20 treatments. It didn’t help at all with my POTS. My insomnia worsened continually during the treatment but I don’t think the treatment caused this, just didn’t slow it down.

Yale ? Study 360 people, 40 days showed more promise ! My treatment showed only a minor improvement.
