Dress for the Dive: The Cotton-First Checklist for Calmer Chamber Sessions

Posted October 16, 2026·Prestige Hyperbaric

A friendly Friday safety guide to what to wear, what to skip, and what to leave on the tray outside before every hyperbaric chamber session.

Here is the least glamorous, most underrated safety tip in the whole hyperbaric world: get dressed on purpose. Before the zipper closes or the hatch seals, the calmest chamber sessions start with a simple question. What is coming in with me, and what can wait on the table outside?

It sounds almost too simple to write about. But in our workshop and on install days, this is one of the first habits we walk owners and operators through, because it is easy to repeat, easy to teach, and it sets the tone for everything that follows. Think of it as packing light for a very short, very relaxing trip.

Why the wardrobe matters in an oxygen-enriched space

A hyperbaric chamber is a different environment from the room around it. Pressure is higher, and depending on the setup there may be concentrated oxygen in use at the mask or in the air around the occupant. Oxygen does not burn by itself, but it helps other materials burn faster and more easily. That is why the best safety programs focus on keeping the inside of the chamber simple: fewer materials, fewer surprises, and nothing that does not need to be there.

The cotton-first rule

Our default recommendation is easy to remember: 100% cotton, loose and comfortable. Cotton scrubs, a cotton t-shirt, cotton sweatpants, and cotton socks make a great chamber outfit. Synthetic blends such as polyester, nylon, and fleece are more prone to building static, so we suggest keeping them for the drive home instead of the session itself.

Many wellness centers keep a stack of clean cotton session wear on hand so guests never have to guess. It is a small hospitality touch that doubles as a safety step, and it makes the whole experience feel more like a spa and less like a checklist. If you run a home program, a dedicated chamber outfit folded next to the unit does the same job.

Skin and hair: keep it fresh and simple

Petroleum-based lotions, oils, ointments, hair sprays, gels, and heavy makeup do not belong in the chamber. Many of these products are flammable, and an oxygen-enriched environment is exactly where you want to remove that variable. The easy version: shower or rinse beforehand if your routine allows, skip the styling products for the session, and save the moisturizer for afterward.

If anyone has a product they rely on for a medical reason, that is a conversation for their healthcare professional and your facility's operating guidelines before the session, not a judgment call in the moment.

The table-outside tray

Here is our favorite trick, and it is the one in today's video: put a small tray on a table outside the chamber. Everything personal goes in the tray before the session starts. Phone, smartwatch, fitness tracker, keys, lighters, hand warmers, earbuds, and jewelry all get a little vacation of their own. When the session ends, everything is waiting in one spot.

A tray turns a list of rules into one visible, friendly step. Guests understand it instantly, operators can confirm it at a glance, and nobody is digging through pockets at the last second. It is the kind of small design detail we love, because it makes the safe choice the easy choice.

A word about electronics

We keep our stance on electronics deliberately conservative. Prestige never endorses personal electronics inside a chamber: no phones, no laptops, no tablets, no smartwatches. Some owners choose to add chamber-installed accessories such as red light, and we do help with those installations, but any electronics used inside a chamber are used at the customer's own risk. Prestige never claims any electronic device is 100% safe in an oxygen-enriched environment. You can read our full position on the electronics disclaimer page.

Make it a two-person habit

The best routines do not depend on one person remembering everything. A quick check between the operator and the occupant takes about thirty seconds: cotton on, products off, tray full. Say it out loud the same way every time. Repetition is what makes a safety habit feel natural instead of formal.

For wellness centers building out their operating procedures, the Prestige NFPA 99 Compliance Kit is designed to help commercial operators work toward the standards referenced for chamber use in a facility setting, and a dressing-and-items check fits naturally into that larger program. For home owners, the same idea scales down beautifully: a folded outfit, a tray, and a moment to look things over.

The Prestige take

We are engineers and technicians first, and we care about the parts of ownership that never show up on a spec sheet. Reliability, safety, and everyday function come from small habits repeated well. A cotton-first outfit and a tray on the table are about as simple as safety gets, and that is exactly why we love them.

Every chamber we deliver comes with hands-on orientation, and we are always happy to walk through session prep with your team. Always follow your chamber's manual, your training, and your facility's operating guidelines.
