How Long Do You Stay in a Hyperbaric Chamber?

Hyperbaric oxygen therapy is one of those sessions people often struggle to judge the timing of before they book. It is longer than a quick drop-in treatment, but it is not the kind of appointment that takes up half a day either.

At Brysk, HBOT sessions are available in 60-minute and 90-minute formats. It also helps to allow a little extra time around the session for arrival, settling in, first-time guidance where needed, and the full flow of compression and decompression, so the whole visit feels calm rather than rushed.

That is the most useful way to think about it: not just the chamber time on paper, but how the appointment actually fits into your day.

The quick answer

Across the wider HBOT space, session length can vary depending on the setup and the purpose of the session.

At Brysk, the answer is simpler: HBOT sessions are available in 60-minute and 90-minute formats.

It also helps to allow a little extra time around that for first-time guidance where needed, compression and decompression, and the general flow of the visit. That gives you a more realistic sense of how the session fits into your day.

How long are HBOT sessions at Brysk?

Brysk offers two HBOT session lengths:

• 60 minutes
• 90 minutes

The 60-minute session is often the more approachable starting point. It gives you the full chamber experience in a format that still feels realistic to plan around.

The 90-minute session suits people who want a more extended chamber visit and are intentionally making space for something longer.

That matters because HBOT is not positioned at Brysk as a quick pop-in treatment. It is a longer, more structured session designed to feel calmer, more immersive, and more deliberate than a short drop-in service.

Chamber time vs total appointment time

When people ask how long they stay in a hyperbaric chamber, they are often mixing together two slightly different questions:

• How long the chamber session itself lasts
• How much time they should allow overall

At Brysk, the chamber session is either 60 minutes or 90 minutes, depending on what you book.

It still helps to allow a little extra time around that for arrival, settling in, and the full flow of the session. That way, the visit feels planned properly rather than squeezed into the smallest possible gap.

If you want a clearer sense of what that full chamber experience actually involves, it also helps to read what happens during a hyperbaric oxygen session.

Why total appointment time can be longer than the chamber time

If it is your first HBOT session at Brysk, it helps to allow a little extra time because the appointment is not just “minutes in the chamber”. Brysk may need to take you through practical guidance, safety procedures, pre-session checks, and the general flow of the chamber before the session starts. The visit also includes compression and decompression time, which is part of how a hyperbaric session is delivered properly rather than an optional extra around it.

Why HBOT takes longer than people expect

Many wellness and recovery sessions are short, which is one reason HBOT can catch people off guard. It does not work like a quick 10 or 15-minute visit where you turn up, do the session, and head straight back into the rest of the day.

HBOT is longer by design. At Brysk, that longer timing is part of the appeal for people who want a calmer, more structured block of time rather than a quick drop-in treatment.

Is 60 minutes enough in a hyperbaric chamber?

Yes. For most first-time users, 60 minutes is the most sensible starting point. It gives you the full chamber experience without asking you to commit to the longer format before you know how it feels for you. At Brysk, that makes it the more approachable first session for many people.

For many people, that shorter format is not a compromise. It is the version that makes HBOT easier to try, easier to plan around, and easier to repeat consistently if it suits them.

Why would someone choose 90 minutes?

The 90-minute option suits people who want a longer oxygen exposure and are intentionally booking a more extended chamber session. For some people, that longer format feels like part of the value rather than just extra time. It gives the session more room to settle, makes sense for people who already know they enjoy HBOT, and may be the better fit for those who want a longer block of structured recovery in the week.

From a value point of view, the 90-minute session also gives you 50% more chamber time than a 60-minute session, while the additional cost is proportionally smaller. For people who already know they suit HBOT well, the longer format can feel like a stronger use of the visit because it gives more chamber time without increasing the cost in the same proportion.

That also fits the wider HBOT landscape, where longer oxygen exposures are common in more protocol-led settings. In clinical hyperbaric practice, treatment times of around 90 to 120 minutes at pressure are frequently used depending on the indication and setup.

When may the longer format make more sense?

The longer format can make more sense if you:

• Already know you respond well to HBOT
• Want a longer oxygen exposure
• Prefer one longer chamber visit over a shorter starting point
• Are deliberately booking a more extended block of recovery time

In the wider HBOT world, longer sessions are also common in more protocol-led settings, including some physician-managed neurological and wound-healing applications. HBOT is also studied in tissue-repair and wound-healing contexts, where oxygen availability forms part of the wider rationale. That still should not be simplified into a blanket promise that a longer session is always better for every person or every goal.

At Brysk, that does not mean 90 minutes is automatically better, and it does not turn a wellness session into medical treatment. It simply means the longer format may feel more worthwhile for some goals and some people than others.

Why 90 minutes is not automatically better

The longer format is not automatically the better option. In some cases, a 60-minute session done consistently may make more sense than jumping straight to the longer format, especially for first-time users or people figuring out how HBOT fits into their routine. At Brysk, the more useful goal is not to chase the longest possible chamber time, but to choose the session length that suits your needs, your response, and how realistically HBOT fits into your routine.

60 vs 90 minutes at a glance

60 minutes often suits:

• First-time users
• People fitting HBOT around work or a busy week
• Anyone wanting a practical starting point
• People who want to see how the session feels before committing to longer chamber time

90 minutes often suits:

• People who already know they enjoy HBOT
• People who want a longer oxygen exposure
• Anyone deliberately booking a more extended recovery block
• People who see the longer format as part of the value of the visit

Does HBOT feel long?

That depends on what you expected before you booked.

If you are comparing it to cryotherapy or red light therapy, then yes, HBOT will feel longer. If you are booking it because you want a calmer, more immersive chamber session, then the longer format usually feels like part of the value rather than a drawback.

That is why HBOT tends to appeal to people who want something more deliberate, not just something fast.

Can you fit HBOT into a workday?

Yes, but it helps to plan for it properly.

Because Brysk’s HBOT sessions in Manchester are 60 or 90 minutes, it usually makes more sense to treat them as a planned block in the day rather than a quick in-and-out appointment.

That does not make HBOT awkward to fit in. It just means it usually works better when you give it proper space, rather than squeezing it into the smallest possible gap.

And if you are planning a first session around work or other commitments, it also helps to know what to wear in a hyperbaric chamber.

So, how long do you stay in a hyperbaric chamber?

Across the wider HBOT space, hyperbaric chamber sessions often fall somewhere in the 60 to 120-minute range.

At Brysk, the chamber session itself is either 60 minutes or 90 minutes, depending on what you book. It simply helps to allow a little extra time around that so the visit does not feel rushed.

That is usually the clearest and most practical way to plan it.
