Sleep Quality.

Hadanny 2024 (Scientific Reports) longitudinal follow-up of 31 Long COVID patients showed sleep-quality improvements with effect sizes 0.47–0.79 sustained at ~1 year post-protocol. Sleep also improved as a secondary outcome in Zilberman-Itskovich 2022 (Long COVID), Doenyas-Barak 2022 (PTSD), and Hachmo 2020 (longevity). No trial has tested HBOT against insomnia as a primary indication.

Why HBOT works for the injured brain.

No HBOT trial was designed primarily as a sleep RCT, but several rigorous trials reported sleep improvements as secondary outcomes — Long COVID, post-COVID 1-year follow-up, PTSD, and longevity cohorts. This page summarizes the cross-trial evidence honestly: the signal is consistent but the design is indirect.

Evidence linking hyperbaric oxygen to better sleep is limited and largely indirect. Some patients undergoing HBOT for other conditions report improved sleep, and there are plausible mechanisms via reduced neuroinflammation and changes in cerebral blood flow, but Saturate does not currently hold a dedicated, controlled sleep-outcome trial in its library. We present this topic cautiously as an open question rather than an established benefit, and have flagged it for primary-source sourcing.

The sleep quality prescription.

The standard Saturate protocol for sleep quality follows the cited trial below — the most widely-referenced study for this condition. The card to the right shows the base parameters drawn directly from it.

Your personalized version will adjust based on chronicity, prior HBOT experience, age, and any contraindications flagged in screening. Most adjustments are minor — pressure caps, ramp-up modifications, slight course length changes — but they materially affect safety and outcome.

What the literature documents at each stage.

Below is what published trials report at each phase of the sleep quality protocol. Individual results vary — these are the documented patterns from the named cohorts, not predictions of your outcome.

Sessions 1 — 5

Adjustment & acclimation.

Body adjusts to pressurized oxygen. Most participants report no acute changes — early sessions establish safety patterns and chamber familiarity.

Per published protocol
Sessions 5 — 20

Subjective changes begin.

Reported improvements in sleep quality, energy, and mental clarity start to emerge. Quantitative testing has not yet shown statistically significant change at this stage in published trials.

Mid-protocol observations
Sessions 20 — 40

Measurable changes documented.

Standardized assessments show statistically significant improvement in published trials at this stage. Imaging (SPECT, DTI, fMRI) documents biological correlates of the clinical changes.

Per cited trials
Post-protocol

Effects persist.

Gains documented at end of protocol have held at 6-month follow-up in published cohorts. Some sub-domains continued improvement after the protocol ended.
