How Many Hyperbaric Oxygen Therapy Sessions Do People Usually Have?
Written by Becky Lumsden, founder of PURE Spa & Beauty · Updated July 2026
One of the first things people ask about hyperbaric oxygen therapy is: "How many sessions do I actually need?" It's a fair question — and the honest answer is that it depends on you. Here's how people tend to use HBOT in practice, and how to keep the cost sensible if you decide to go regularly.
In short: there's no fixed number. Many people start with a single session to try it, then move to a course of six or an Access Pass (5, 10 or 30 sessions) if they want HBOT as a regular part of their routine. HBOT is generally used cumulatively rather than as a one-off, and buying in blocks brings the per-session price down — from £45 for a single 30-minute session to about £23 a session on a 30-session pass.
How people usually build it up
Step 1 · Just try it
A single session
The best place to start. One 30- or 60-minute session lets you see how HBOT feels and whether you'd want to go again — no commitment, no block booking.

Step 2 · Make it a routine
A course or an Access Pass
If you've decided HBOT is for you, buying in a block is where it gets good value. A 6-session course works out cheaper per session, and an Access Pass of 5, 10 or 30 sessions is designed for people who want to go often over time.

| Option | Sessions | Price | Per session |
|---|---|---|---|
| Single session (30 min) | 1 | £45 | £45 |
| 6-session course (30 min) | 6 | from £225 | £37.50 |
| HBOT Access Pass | 5 | £345 | £69 |
| HBOT Access Pass | 30 | £695 | ≈ £23 |
| Membership | pay monthly | — | from £33.17 |
So the more regularly you plan to go, the more a pass or membership makes sense. If you're still deciding, there's no harm in a single session first — see the full breakdown on the HBOT guide.
A word on expectations
It's worth being straight: people respond differently, and HBOT is generally something people use as part of a wider wellness routine rather than a quick fix. Research is still exploring hyperbaric oxygen's role in recovery and wellbeing, so we'd always rather you tried a session and judged for yourself than took a number off the internet as gospel. Your therapist can talk through what's realistic for your goals and schedule.
Thinking of going regularly? A course or Access Pass is the most cost-effective way in — and you can always start with one session to be sure.
Where to book
HBOT is available at four PURE spas: Edinburgh (Lothian Road), Glasgow (West Nile Street), Aberdeen (Union Square) and Witney Lakes, Oxfordshire.
Your questions, answered
How many HBOT sessions do people have?
It varies by person and goal. Many start with a single session, then build up with a 6-session course or an Access Pass of 5, 10 or 30 if they want HBOT as a regular routine. It's generally used cumulatively rather than as a one-off.
How often should you do HBOT?
There's no single rule — anything from occasional sessions to several a week. If you're going regularly, a course or pass keeps the per-session cost down. Your therapist can help you plan something realistic.
What's the cheapest way to do HBOT regularly?
Buying in blocks: a 6-session course from £225 (£37.50/session) or a 30-session Access Pass at £695 (about £23/session), versus £45 for a single session. Membership can work out from around £33 a session.
Do you need more than one session?
No — you can have a single session, and many people do. But HBOT is typically used cumulatively, so regular users tend to book a course or pass.
