What does an HBOT session actually feel like?
If you’ve never experienced hyperbaric oxygen therapy before, it’s natural to wonder what happens during your time inside the chamber.
As our chamber is the biggest in the UK, it can feel more relaxing to be able to walk in and sit down, without feeling claustrophobic or uncomfortable.
Once inside, and as the chamber gradually pressurises, you may notice a slight change in pressure in your ears, a bit like travelling in an aeroplane, but the feeling passes quite quickly.
Once the pressure stabilises, you can settle back and relax while breathing oxygen through your mask.
At the end of your session, the chamber is slowly returned to normal pressure before you leave.
