BREATHE IN OXYGEN. HEAL YOUR BRAIN.
Hyperbaric Oxygen Therapy for Concussion & Brain Injury
Safe, at-home Hyperbaric Oxygen Therapy (HBOT) helps increase oxygen delivery to injured brain tissue, reduce inflammation, and support recovery from concussion, post-concussion syndrome, and mild traumatic brain injury (mTBI).
At Cocoon, your therapy is delivered in the comfort of your home with unlimited sessions, personalised protocols, and expert clinical guidance, allowing you to follow a structured recovery programme without the limitations of clinic-based treatment.
Why you still don’t feel like yourself
Many people are told to “just rest” after a concussion. Yet weeks or months later, symptoms often remain.
You may still be experiencing headaches, brain fog, difficulty concentrating, light or noise sensitivity, dizziness, fatigue, mood changes, or the unsettling feeling that you’re simply not the same as before.
After a head injury, parts of the brain can remain low in oxygen and struggling to repair, even after the initial injury has healed.
Hyperbaric Oxygen Therapy (HBOT) helps address this by increasing dissolved oxygen in the blood and cerebrospinal fluid, allowing oxygen to reach areas where circulation has been reduced after injury.
At Cocoon, we provide at-home HBOT programmes with unlimited sessions, so you can support your brain’s recovery consistently and comfortably.
How HBOT Helps After Concussion / Traumatic Brain Injury
More oxygen where it’s needed
Pressurised oxygen dissolves directly into the bloodstream and cerebrospinal fluid, reaching areas of the brain where blood flow may have been reduced after injury.
Reduces neuroinflammation
Improved oxygen availability supports the body’s natural anti-inflammatory processes, helping calm ongoing irritation in brain tissue.
Supports cellular energy
Oxygen is essential for ATP production — the energy source used by cells. Increased oxygen availability helps support brain metabolism, focus, and recovery.
Encourages repair
With improved oxygen delivery and energy production, the brain is better supported in repairing damaged tissue and restoring function.
Many patients report clearer thinking, fewer headaches, improved sleep, and steadier balance as sessions accumulate.
Concussion Recovery with Hyperbaric Oxygen Therapy
Benefits of At-Home HBOT for Concussion & Post-Concussion Syndrome (PCS)
-
Deeper Oxygen Delivery to Injured Brain Tissue
Pressurised, oxygen-rich air increases dissolved oxygen in the blood and cerebrospinal fluid, reaching areas with reduced blood flow after concussion/mTBI.
-
Calms Neuroinflammation & Eases Symptoms
Supports the body’s anti-inflammatory response, helping reduce headaches, light/noise sensitivity, pressure, and overall brain irritation.
-
Restores Cellular Energy & Supports Repair
Improved oxygen availability boosts mitochondrial ATP and supports neuroplasticity, aiding clarity, memory, processing speed and mental stamina.
-
Stabilises Balance & Autonomic Function
Helps vestibular recovery to lessen dizziness/disequilibrium and, when present, supports management of dysautonomia/POTS related to concussion.
-
Improves Sleep, Energy & Mood
Better oxygenation often leads to more restful sleep, steadier daytime energy, and calmer mood, making it easier to stick with recovery.

FAQs
-
Everyone heals differently. Some people feel improvements in sleep or headaches within the first 1–2 weeks; others notice steady gains across the full 6 weeks.
-
Most concussion plans recommend sessions most days (60–90 minutes), especially in the first month, then we adjust to your progress.
-
Yes. Many clients with persistent PCS symptoms use HBOT to support ongoing recovery.
-
We assess case-by-case. Once you’re medically stable, HBOT can be introduced alongside rest and rehabilitation.
-
HBOT is generally not covered in NZ outside hospital indications. Our flat-rate 6-week rental keeps costs affordable and predictable.
