What To Wear In A Hyperbaric Chamber: Essential Guidelines For Comfort & Safety
Preparing for a hyperbaric oxygen therapy (HBOT) session goes beyond simply scheduling your appointment. One of the most common questions new patients have is: What To Wear In A Hyperbaric Chamber? While the therapy itself is designed to deliver high concentrations of oxygen to heal wounds, enhance recovery, or treat various medical conditions, your clothing choices directly influence both safety and session effectiveness.
The chamber environment is pressurized, which means any synthetic materials or improperly chosen items can become fire hazards (since concentrated oxygen is highly flammable) or sources of discomfort. Below, we break down the essential clothing tips to ensure a safe, friction-free, and effective hyperbaric session.
For an in-depth breakdown of acceptable materials, strict restrictions, and what to definitively avoid, refer to this comprehensive guide on What To Wear In A Hyperbaric Chamber to align with the industry safety protocols.
100% Cotton: The Gold Standard For Hyperbaric Attire
The most fundamental rule for What To Wear In A Hyperbaric Chamber is the strict use of 100% cotton fabric. Cotton is the only naturally fire-retardant common fabric; it does not melt onto the skin in a fire event like synthetics do. Patients are typically provided with—or required to bring—standard cotton scrubs or a loose-fitting T-shirt and pants without buttons, snaps, zippers, or metal clips.
Why cotton matters: When you compress the oxygen concentration inside a chamber, even a stray static spark from polyester rubbing against the bed or walls can become dangerous. Cotton significantly reduces static buildup. Avoid fleece, wool, denim, spandex, or blended “athletic wear.” Your attire should have minimal seams, no drawstrings (which can be choking hazards via oxygen hood straps), and no pocket contents. Hospitals often refer to these as “scrub clothes” or “CB-approved (cancer board) non-synthetic sleepwear.”
Footwear And Socks: Skip Shoes, Embrace Grip Socks
This topic ranks high in patient FAQs. the answer to What To Wear In A Hyperbaric Chamber for your feet is simple: you cannot wear regular shoes. Street shoes carry dirt, chemical residues, and metal parts (eyelets, steel shanks, soles) that are not allowed inside a monoplace or multiplace chamber. Most clinics require you to remove all footwear at the chamber room door.
What you can wear: a clean pair of 100% cotton tube socks or non-skid hospital socks provided by the facility. Some clinics permit lightweight, brand-new cotton slippers with no rubber soles. Brand-new pairs bought from a sterile bulk pack are safest for infection control. If you have ill-fitting socks, you’ll be more uncomfortable while lying down for 60–120 minutes, so choose seamless, cushioned, natural-fiber options.
Avoiding Belts, Jewelry, And Eyewear
Your personal items rule list is critical for patient preparation. Belts, buckles, hair clips, rings (including simple wedding bands), bracelets, necklaces, watches, hearing aids, canes, and glasses are prohibited for three big reasons:
