Hyperbaric Oxygen Therapy (1.5 ATA)

A 60-minute hyperbaric oxygen therapy session at 1.5 ATA — the standard pressure tier at House of Salt. The higher pressure compared to the 1.3 ATA option increases the partial pressure of oxygen in the bloodstream, which may provide enhanced support for tissue repair, inflammation reduction, and recovery.

The 1.5 ATA HBOT session at House of Salt delivers a higher atmospheric pressure than the entry-level 1.3 ATA option — roughly 50% above normal sea level, equivalent to approximately 5 metres below the water surface. This increased pressure further raises the partial pressure of dissolved oxygen in blood plasma, potentially enhancing tissue oxygenation beyond what the 1.3 ATA tier achieves. At 1.5 ATA, the session sits in the upper range of what mild/wellness-tier HBOT chambers typically deliver. The 60-minute session duration is shorter than the 1.3 ATA option (90 minutes), reflecting the higher intensity of the pressure stimulus. The physiological responses at this pressure are well-documented: enhanced oxygen diffusion into tissues, upregulation of growth factors involved in wound healing, modulation of inflammatory pathways, and support for immune cell function. Published research on 1.5 ATA HBOT has explored applications across post-concussion recovery, sports performance, wound healing, and general wellness. While the most robust clinical evidence for HBOT applies to higher pressures (2.0-2.4 ATA) used in hospital settings for conditions like non-healing wounds and decompression sickness, the 1.5 ATA tier has shown promise in wellness and recovery contexts. Priced at 580 DKK for 60 minutes, this is the standard HBOT session at House of Salt. Clients who want both the higher pressure and extended duration can upgrade to the 90-minute extended session at 780 DKK.
