Hyperbaric oxygen therapy has a reputation for being intimidating — claustrophobic pods, hospital settings, high-pressure chambers reserved for wound care or decompression sickness. The experience at Lost in Float is none of those things.
You sit in a comfortable reclining chair, watch TV if you'd like, breathe oxygen through a cannula, and let the mildly pressurized environment do its work. Sixty minutes later, you're done. The setup is specifically designed around comfort — because a relaxed body is more receptive to the benefits of increased oxygenation than a tense one.
Before we get into what it's like here, it's worth understanding what HBOT actually is, what the research says at wellness pressure levels, and what you can honestly expect.
HBOT research spans a wide range of pressures and clinical protocols. Much of the strongest published evidence refers to higher-pressure medical HBOT used in hospital settings for specific diagnosed conditions. At Lost in Float, we offer a wellness-focused HBOT experience at lower pressure levels — for general wellness, recovery, and self-optimization. We are not making medical claims. If you have a medical condition, consult your doctor before starting.
What Is HBOT?
Hyperbaric oxygen therapy involves breathing oxygen inside a gently pressurized chamber. The increased atmospheric pressure allows your lungs to absorb more oxygen than would be possible at normal air pressure. That oxygen-enriched blood then travels throughout the body — reaching tissues, joints, and organs more effectively than at baseline.
Normal atmospheric pressure at sea level is 1 ATA (atmosphere absolute). HBOT operates above that. Clinical medical HBOT typically runs at 2.0–3.0 ATA. Wellness-focused mild HBOT — like what we offer — operates at lower pressure levels in the range of approximately 1.3–1.5 ATA. The experience and risk profile at these levels is meaningfully different from clinical settings.
| Mild / Wellness HBOT | Clinical Medical HBOT | |
|---|---|---|
| Pressure | ~1.3–1.5 ATA | 2.0–3.0 ATA |
| Setting | Wellness centers, recovery clinics | Hospitals, medical hyperbaric units |
| Oxygen delivery | Cannula — comfortable, easy to wear | Mask or hood; 100% oxygen |
| Typical use | Recovery, wellness, performance, general oxygenation | Wound healing, decompression sickness, CO poisoning |
| Side effect risk | Minimal — ear equalization most common | Higher — oxygen toxicity risk increases above 2.0 ATA |
| Prescription required | No | Yes — for approved indications |
How It Works — The Mechanisms
The core mechanism is straightforward: under increased atmospheric pressure, more oxygen dissolves directly into blood plasma — not just into red blood cells. This is governed by Henry's Law of Gases. The result is that oxygen reaches tissues through a different route than normal, potentially accessing areas where blood flow or red blood cell delivery is limited.
Beyond simple oxygenation, research has explored several additional mechanisms at various pressure levels:
- Enhanced tissue oxygenation: Plasma-dissolved oxygen can reach hypoxic (low-oxygen) tissue that red blood cells may struggle to access — particularly in areas of inflammation, injury, or reduced circulation.
- Inflammation modulation: Research at 1.3 ATA has documented reductions in pro-inflammatory cytokines including interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) — markers associated with chronic inflammation, fatigue, and impaired recovery.
- Mitochondrial function: Increased oxygen availability supports ATP production — the energy currency of cells. This is particularly relevant for cognitive function and muscle recovery, both of which are highly oxygen-dependent.
- Immune modulation: Some mild HBOT research has documented effects on natural killer (NK) cell activity and broader immune function, suggesting a role in immune system support.
- Stem cell mobilization: Higher-pressure protocols have documented modest stem cell mobilization. At mild wellness pressures, this effect is present but less pronounced — still a proposed mechanism for tissue repair and recovery support.
What the Research Shows at Wellness Pressure Levels
It's important to be honest about where the evidence is strong and where it's still developing — particularly at the lower pressure range used in wellness settings.
What the research supports at mild pressures
Studies at wellness pressures (approximately 1.3–1.5 ATA) show consistent findings in several areas. Research has documented improved recovery from physical exertion, reduced perceived fatigue, and lower circulating inflammatory markers in people receiving regular mild HBOT sessions. A study involving rugby players found those using mild hyperbaric chambers post-exercise showed faster reductions in creatine kinase levels (a measure of muscle damage) and lower soreness scores compared to controls.
Systematic reviews of HBOT and cognitive function — including a comprehensive 2022 review in Neuropsychology Review — document improvements in memory, executive function, information processing speed, and global cognitive scores across multiple studies, primarily at 1.5–2.0 ATA with 100% oxygen. At wellness pressure levels with supplemental oxygen via cannula, the oxygenation delivered is lower than these clinical protocols — but the directional findings are consistent.
Some evidence also exists for low-pressure HBOT improving symptoms associated with long COVID — including brain fog, fatigue, and reduced exercise tolerance — though this research is newer and ongoing. Results vary by individual, protocol, and consistency of use.
Where to be appropriately skeptical
Many of the most striking wellness benefits attributed to HBOT are based on user reports, smaller studies, or research conducted at higher pressures than wellness settings use. Larger, well-controlled trials specifically at 1.3–1.5 ATA for general wellness outcomes are limited. Results vary significantly by individual, the specific protocol used, consistency of sessions, and what outcomes are being measured. HBOT is not a cure or medical treatment for any condition — it's a wellness tool, and it works best as part of a broader routine that includes sleep, nutrition, and movement.
What to Expect at Lost in Float
Most people's mental image of HBOT involves lying flat inside a narrow tube. Our setup is genuinely different — and that difference matters for both comfort and effectiveness.
We'll run through a short pre-session screening — any recent surgeries, ear or sinus issues, respiratory conditions, or medications that might be relevant. Wear comfortable, loose clothing. Remove metal jewelry. No special prep is required beyond that.
You settle into a reclining chair — not a pod, not a narrow tube. The chamber is roomy. You'll receive a cannula for oxygen delivery — a small, comfortable nasal insert. TV is available. Many people read, rest, or simply relax. Staff remain nearby throughout.
As the chamber reaches its working pressure, you'll notice a subtle sensation in your ears — similar to descending on an airplane. This passes quickly. Equalize by swallowing, yawning, or gently pinching your nose and blowing gently (the Valsalva maneuver). Our staff guide you through this on your first session. Once pressure is stable, you feel nothing unusual — just sitting comfortably.
The session itself is straightforward. Breathe normally through the cannula. Watch something, listen to something, or rest. Many people find it genuinely relaxing — some doze off. The chamber does its work without any effort on your part. If you ever feel uncomfortable, staff can adjust or end the session.
Drink water. Avoid intense physical activity immediately after your first few sessions while you understand your response. Most people report feeling clear-headed and calm — some notice a mild, pleasant energy in the hours that follow. Deeper effects tend to build with consistent sessions over time, not from a single visit. For best results, 1–3 sessions per week is a typical starting protocol.
Safety, Side Effects & Contraindications
At wellness pressure levels, HBOT has a strong safety profile. Understanding the full picture builds appropriate expectations.
Common and mild: Ear or sinus pressure during pressurization (like flying — equalizes easily by swallowing or yawning). Temporary mild fatigue or lightheadedness after the first session or two as your body adjusts. Dry mouth or nose from the oxygen delivery.
Less common: Temporary mild vision changes (slight myopia) with very frequent use over weeks — this is self-resolving when sessions pause or end. Headache in some first-timers, typically from not equalizing ear pressure adequately.
Rare at wellness pressures: Barotrauma (pressure injury to ears or sinuses) is rare but possible if equalization is not done properly — staff guidance on your first session significantly reduces this risk. Oxygen toxicity is a real concern at high pressure (above 2.0 ATA with 100% oxygen) but the risk is substantially lower at wellness pressure levels with cannula delivery rather than mask delivery of 100% oxygen.
Consult your doctor before using HBOT if you have: an untreated pneumothorax (collapsed lung), active ear or sinus infection, recent ear surgery, certain lung conditions (emphysema with CO2 retention), a history of spontaneous pneumothorax, uncontrolled high fever, or are pregnant. People with claustrophobia should discuss the seated chamber setup with us before booking — many find it significantly more accessible than they expect, but it's worth having the conversation. If you are on any medication, particularly those affecting oxygen sensitivity, check with your prescribing provider.
At our wellness pressure levels in a comfortable seated setup, the vast majority of people tolerate HBOT easily and well. Our staff walk every first-timer through equalization and monitor throughout the session.
Who It's For
Post-training muscle recovery, reduced soreness, faster return to performance. Many use it the day after hard training or competition.
People managing brain fog, cognitive fatigue, or looking to support mental clarity and focus. Consistent sessions reported to improve perceived cognitive function.
Those managing persistent fatigue or low-grade inflammation who want a non-stimulant approach to supporting energy and recovery at the cellular level.
People already committed to their health who want to add enhanced oxygenation to a stack that includes sauna, cold plunge, red light, and float therapy.
Emerging evidence supports mild HBOT for symptoms including fatigue, brain fog, and reduced exercise tolerance. An area of active research and growing clinical interest.
Mitochondrial function, inflammation reduction, and cellular repair are all relevant to healthy aging. HBOT's mechanisms align with the most evidence-informed longevity interventions.
How HBOT Fits Your Wellness Routine
HBOT works well as a standalone practice. It compounds meaningfully when paired with the other services at Lost in Float — each addressing different but complementary aspects of recovery and performance.
- Float therapy — Float addresses nervous system regulation and gravitational decompression; HBOT adds enhanced oxygenation. Together they cover both the relaxation-recovery axis and the cellular energy axis. Many members pair them on the same visit or alternate days.
- Red light therapy — Red light stimulates mitochondrial ATP production through photobiomodulation; HBOT delivers more oxygen to fuel that production. The two work on the same cellular energy system through different inputs. Read the red light guide →
- Sauna — Heat exposure and HBOT both drive inflammation modulation and circulatory response, through completely different mechanisms. Sauna on one day, HBOT on another is a practical pairing for members focused on inflammation management.
- Cold plunge — Cold reduces inflammatory markers through vasoconstriction; HBOT addresses the oxygenation side of the same recovery equation. Together they address recovery from multiple angles simultaneously.
The Lost in Float Recovery Stack brings all of these together into a structured protocol — HBOT is now part of that full stack for Gold and Platinum members.
Honest Expectations
HBOT is not a cure and not a substitute for medical care, sleep, nutrition, or movement. At wellness pressure levels, it's a tool that supports the body's natural recovery and optimization processes — most effectively when used consistently as part of a broader routine.
Some people notice subtle clarity or energy after their first session. Others feel nothing unusual at first and notice cumulative effects building over weeks of regular use. Both experiences are normal. Individual results vary based on your baseline, what you're using it for, how consistently you come, and how it integrates with the rest of your routine.
For most people, 1–3 sessions per week for several weeks is where meaningful cumulative benefit becomes noticeable. A Lost in Float membership makes this frequency financially practical — HBOT is included with Gold and Platinum tiers, and all other members receive 50% off.
