Post-Surgery & Injury Recovery

Recovery after surgery or injury taking longer than you'd like?

Recovering from surgery or a significant injury takes time, energy and patience — and many people find themselves wondering whether there is anything else they can do to support their recovery. Cocoon offers guided, at-home hyperbaric oxygen therapy (HBOT) that some people choose to explore as part of their wider recovery plan, alongside the guidance of their own medical team.

Does this sound familiar?

When recovery feels like slow going

After surgery or a significant injury, the body has a lot to do — and recovery comes with its own challenges. If several of these feel familiar, you're not alone.

Pain or discomfort Swelling Fatigue Reduced mobility Stiffness Scarring Disrupted sleep Low energy Reduced fitness Frustration with slow progress

These are common parts of recovering from surgery or injury. If you're looking for ways to support the process, it may be worth exploring your options alongside your medical team.

Understanding recovery

Why recovery after surgery or injury takes time

After surgery or injury, the body works through a series of natural stages — managing inflammation, rebuilding tissue and gradually restoring strength and movement. That process takes energy and time, and it looks different for everyone.

Things like the type of procedure or injury, your overall health, sleep and activity levels can all influence how recovery feels day to day, which is why a steady, well-supported routine — guided by your medical team — matters.

Every recovery journey is different. Whether you're recovering from surgery or a significant injury, any decisions about additional therapies should be discussed with your treating medical team.

About the therapy

Why some people explore HBOT during recovery

Hyperbaric oxygen therapy isn't a cure or a shortcut, and it doesn't replace the care of your surgeon or medical team. But some people choose to explore HBOT as one part of their wider recovery plan. Here's what it actually involves.

01

Oxygen under gentle pressure

During a session you breathe oxygen-enriched air while the chamber is gently pressurised, allowing more oxygen than usual to dissolve into your bloodstream.

02

Dissolved oxygen circulates through the body

That dissolved oxygen circulates in the blood throughout the time you spend in the chamber, reaching tissues around the body.

03

Part of a wider recovery

People generally use HBOT as one part of a broader routine — alongside rest, rehabilitation and the advice of their own health professionals.

Whether HBOT is a sensible fit depends entirely on your situation, and it isn't right for everyone. We'd always encourage you to check with your surgeon or medical team first, and our team will talk it through with you honestly before you decide anything.

The Cocoon difference

Why at-home HBOT is different

Most hyperbaric therapy means travelling to a clinic for short, scheduled appointments. Cocoon brings the chamber to you — which changes how easily it fits into your life.

Traditional clinic-based HBOT

  • Travelling to and from each appointment
  • Fixed, limited session times
  • Fitting around the clinic's availability
  • Waiting rooms and parking

At home with Cocoon

  • Your chamber is installed in your own home
  • Unlimited sessions across your programme
  • Use it at the times that suit your day
  • No travel, no waiting rooms

Consistency is often one of the biggest challenges in any recovery programme. Having your chamber available at home can make it easier to build therapy into everyday life.

Meet your guide

Guidance from Dr Gary Dennis

DC (USA) · MMC (AUS) · Dip HBOT (USA) · NZCA

Dr Gary Dennis has spent much of his career supporting people with complex and chronic health challenges, with a special interest in neurological recovery and dysautonomia. His own experience recovering from a serious brain injury led him to explore hyperbaric oxygen therapy and the role that consistent access can play within a broader recovery programme.

Every Cocoon programme begins with a personal conversation with Gary to understand your situation, answer your questions and determine whether at-home HBOT may be appropriate for your goals. From installation through to ongoing support, you'll have direct access to guidance throughout your programme.

How it works

Your Cocoon programme

Recovery takes time, and everyone's path is different. Here's how a Cocoon programme works — from the first conversation through to ongoing support.

1

Consultation

We start with a conversation about your symptoms, history and goals, to understand whether HBOT is a sensible fit for you.

2

Personalised HBOT programme

If it's appropriate, we map out a programme — session length, frequency, and how it fits around your routine.

3

At-home therapy

Your chamber is installed in your home, giving you convenient access to HBOT without travelling to appointments or fitting sessions around clinic schedules.

4

Ongoing support

We stay in touch throughout your programme, checking in and adjusting your plan as you go.

Common questions

Recovery, HBOT & what to expect, answered

How long does recovery after surgery or injury usually take?
It varies widely depending on the type of procedure or injury, your overall health and how recovery progresses. Your surgeon or medical team can give you the best guide for your situation and what to expect along the way.
When should I start thinking about recovery support options?
Recovery timelines vary depending on the procedure or injury. Any decisions about additional therapies should always be discussed with your surgeon, specialist or treating healthcare professional.
Why does recovery often feel so tiring?
Recovering takes real energy — the body is working hard, and pain, disrupted sleep and reduced activity can all add to fatigue. Feeling more tired than usual during recovery is very common.
What can help support recovery after surgery or injury?
Recovery is usually supported by the basics done well — following your medical team's advice, rest, good nutrition, sleep, and gradually returning to movement as you're cleared to. Some people also explore additional options such as hyperbaric oxygen therapy (HBOT) as part of that wider plan. It isn't a cure or a shortcut, and it's something to consider alongside — not instead of — your surgeon's guidance.
Does HBOT speed up healing?
We can't claim that, and HBOT isn't a cure or a shortcut. Some people choose to explore it as one part of their wider recovery, but whether it's sensible for you depends on your individual situation. The most important thing is to follow the recovery plan set by your surgeon or medical team.
Can I use HBOT after surgery?
That depends on the type of surgery, how your recovery is going and the timing — which is exactly why it needs to be discussed with your surgeon or medical team first, and why every Cocoon programme starts with a conversation to check whether it's appropriate.
Is HBOT safe after surgery or injury?
HBOT is generally well tolerated, but it isn't suitable for everyone and there are situations and conditions where it isn't recommended. We'd always want you to have clearance from your medical team, and every programme begins with a conversation to check it's appropriate for you.
What does a typical HBOT programme at Cocoon involve?
A typical Cocoon programme runs over about six weeks using a chamber installed in your home. Session length and frequency are mapped out with you based on your situation, so the routine fits around everyday life and your recovery.
Is it covered by ACC or insurance?
Coverage varies and isn't guaranteed. If your situation relates to an injury, some people check with ACC about whether any support is available, or with their private insurer. We're happy to provide information you can pass on, but we can't advise on individual claims.

“I used the Cocoon mHBOT after hip surgery and, while the early effects were subtle and inflammation ticked up briefly in week one, it settled within 1–2 weeks and over 2–3 months I recovered faster - an alternate-day 90-minute routine eased tendon pain, supported wound healing, and seemed to strengthen deep scarring, with no side effects. I’m continuing long-term because it feels safe and genuinely helpful, and I highly recommend Gary -knowledgeable, reassuring, and excellent service.”
