Conditions & wellbeing

Find the area that best matches your situation

Whether you're dealing with post-concussion symptoms, Long COVID, chronic pain, dysautonomia, recovery after surgery, or simply looking to support your wellbeing during a challenging health journey, we've created dedicated guides to help you understand where HBOT may fit.

Each page gives an honest, plain-language overview — what HBOT involves, who it may suit, and whether an at-home programme could be worth exploring alongside your own care.

What people are looking for

Why people explore HBOT

People come to Cocoon from many different health backgrounds, but most are looking for the same kinds of things — more energy, better recovery, an improved quality of life, support alongside the care they already have, or simply a way to stay consistent with a routine.

HBOT isn't a cure, and it isn't appropriate for everyone. Some people choose to explore it as one part of a broader wellbeing or recovery plan, under the guidance of their own healthcare team.

No hype, no pressure

An honest conversation about HBOT

Hyperbaric oxygen therapy involves resting in a gently pressurised chamber and breathing oxygen-enriched air. It isn't a cure, and it isn't right for everyone.

Some people choose to explore it as one part of a wider wellbeing or recovery plan, alongside the care of their own clinicians. Every Cocoon programme is guided by Dr Gary Dennis and begins with a conversation to talk it through honestly — and if we don't think it's the right fit for you, we'll say so.

Common questions

Frequently asked questions

Which condition page should I start with?
Start with whichever area is closest to what you're experiencing — each page gives an honest overview for that situation. If several feel relevant, or none feels like an exact match, that's common, and the simplest next step is a quick conversation with our team.
Can HBOT be used alongside my existing treatment plan?
For many people, HBOT is just one part of a wider routine alongside the care they already have. It doesn't replace your existing treatment, and any decisions are best made with the people managing your care — for some conditions we'd want their input before you start.
Do I need a referral?
No referral is needed to talk to us. That said, for some health conditions we'd want input from your own doctor or specialist before starting, and every programme begins with a consultation to check whether HBOT is appropriate for you.
How often is HBOT typically used?
It varies from person to person and is mapped out after your consultation. Because the chamber is installed in your home, many people use it regularly across a programme — that consistency is part of why people choose the at-home model.
Is at-home HBOT safe?
HBOT is generally well tolerated, and your chamber is delivered, installed and explained by our team. It isn't suitable for everyone, though, which is why every programme starts with a consultation to check it's appropriate for you.
What if I'm not sure which condition fits me?
That's completely normal — many people don't fit neatly into one box. Have a no-obligation conversation with our team about what you're experiencing, and we'll help you work out whether an at-home HBOT programme is a sensible fit. If it isn't, we'll tell you. You can get in touch here.
