Under increased pressure, more oxygen dissolves directly into blood plasma rather than riding on hemoglobin — which means oxygen reaches tissue through a second pathway your circulation doesn't normally use. At 1.3 ATA breathing air, plasma oxygen concentration is estimated to increase roughly 30–40% over sea-level breathing, and higher with oxygen-enriched air.

A systematic review screening 1,510 studies and including 16 that met eligibility criteria — spanning 1.3 to 2.5 ATA, with comparators including sham and passive recovery — found most reported benefits for oxygen saturation, muscle soreness reduction, and post-training recovery.

A 2025 systematic review of 18 studies (17 RCTs, 671 participants), found consistent reductions in pain and modest functional improvements in fibromyalgia and postoperative conditions, alongside improvements in inflammatory markers. In one postoperative protocol, HBOT was associated with reduced swelling during the first week.
