our brain is an oxygen furnace. Here is why researchers are interested.
Your brain uses around a fifth of all the oxygen you take in, despite being a small fraction of your body weight. It is hungry for it. Because hyperbaric oxygen dissolves into the cerebrospinal fluid that bathes your brain and spinal cord, researchers are actively exploring its effects on focus, memory and mental fog, and its potential to support neuroplasticity, the brain's ability to adapt and rewire.
This is an area of active study, not a cure. If you are dealing with a health condition, please speak to your GP.
