Mild Hyperbaric Oxygen Therapy FAQs

Here are some of the most common things people want to know before their first session.

How will I feel during and after?
Most people find sessions deeply restorative — many nap or simply rest. Afterwards, you’ll usually feel more awake and energised. A small number of people experience brief fatigue (about 10 minutes) as the body resets.

What does it feel like in the chamber?
You may feel your ears adjust, similar to flying or diving, as the chamber gently pressurises. Once inside, you rest in comfort — read, listen to music, or nap — while your body takes in extra oxygen.

Is mHBOT safe?
Yes. Mild hyperbaric oxygen therapy is safe and well tolerated by most people, across all ages.

Who shouldn’t use it?
There are a few situations where mHBOT may not be suitable, including:

• Pneumothorax (collapsed lung)

• Certain types of emphysema or COPD

• Severe heart conditions

• Ear or sinus infections, or a head cold

• Uncontrolled seizures or very high fever

• Recent eye surgery or conditions

• Certain medications (our team will check this with you)

• Pregnancy (not suitable for mHBOT)

How long is a session?
Standard sessions run 60–120 minutes. Sessions under 60 minutes are generally considered introductory only and provide limited benefit.

Will I notice benefits from just one session?
A single session may provide a short-term boost — many people feel more energised or refreshed afterwards. It can also be helpful immediately after an injury, surgery, or a particularly demanding period. However, the real therapeutic results usually come from a series of regular sessions. That’s when oxygen levels can build up in the body and support deeper healing, recovery, and wellbeing.

What should I wear?
Wear loose, comfortable clothing. You’ll stay dressed during your session, and the chamber is fitted with a bed, pillows, and blanket for your comfort.

What can I do inside?
You can relax however you like — read, listen to music, meditate, or sleep.

How do I communicate during treatment?
You’ll have a two-way radio so you can speak to our team at any time.

What if I’m claustrophobic?

The chamber is a relatively compact, pressurised space — spacious enough for an adult to lie down comfortably — but once a session begins, it cannot be opened immediately (decompression usually takes about five minutes). For this reason, hyperbaric oxygen therapy is not suitable for people with claustrophobia.

If you are mildly apprehensive, or if you have occasional sinus issues, slightly sore ears when flying, or other minor health concerns that should be monitored, we recommend the option of starting with a 30-minute introductory session. This allows you to proceed cautiously, while giving us the opportunity to monitor how you respond before moving on to a full treatment session.

How many sessions will I need?
That depends entirely on your health goals and situation. Our team will discuss a plan with you and guide you through what’s likely to be most effective.
