CONCUSSION AND BRAIN INJURY RECOVERY WITH HBOT

Breathe in Oxygen. Heal Your Brain.

Safe, at-home Hyperbaric Oxygen Therapy (HBOT) to increase oxygen to injured brain tissue, calm inflammation, and restore clarity after concussion, post-concussion syndrome, or mild traumatic brain injury (mTBI).

Why you still don’t feel like yourself

Many people are told to “just rest” - yet symptoms linger: headaches, brain fog, difficulty focusing, light or noise sensitivity, dizziness, constant fatigue, mood changes, or that unsettling sense you’re simply not the same as before.

After a head injury, parts of the brain can be low in oxygen and struggling to repair. Hyperbaric Oxygen Therapy (HBOT) is a safe, non-invasive therapy that increases dissolved oxygen in the blood (and cerebrospinal fluid), reaching areas with reduced blood flow and supporting natural brain healing. At Cocoon, we tailor an at-home HBOT programme with unlimited sessions, so you can recover where you feel most comfortable.

How HBOT Helps After Concussion / Traumatic Brain Injury

More oxygen where it’s needed: Pressurised air helps oxygen dissolve more deeply into blood and tissues, reaching areas under stress after injury.

  • Calms inflammation: Better oxygenation supports the body’s natural anti-inflammatory response.

  • Supports cellular energy: Oxygen is the key ingredient for ATP (cell energy) - essential for focus, balance, and recovery.

  • Encourages repair: With improved oxygen and energy, the brain has what it needs to heal.

Many clients report clearer thinking, fewer headaches, improved sleep, and steadier balance as sessions accumulate.

Benefits of At-Home HBOT for Concussion & Post-Concussion Syndrome (PCS)

  • Deeper oxygen delivery to injured brain tissue

    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

    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

    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

    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
