What to Wear in a Hyperbaric Chamber: The Complete Safety & Comfort Guide
Entering a hyperbaric oxygen therapy (HBOT) chamber can feel like a step into the unknown. One of the most common and crucial questions patients have is about proper attire. Wearing the right clothing is not about fashion—it’s a fundamental part of safety and comfort during your treatment. This guide will walk you through everything you need to know about what to wear in a hyperbaric chamber.
Why Your Clothing Choice Matters for HBOT Safety
Inside the pressurized environment of a hyperbaric chamber, certain materials can pose a serious fire risk due to the increased oxygen levels. Static electricity, sparks, or friction from synthetic fabrics can become hazardous. Therefore, clinic safety protocols are strict, and your clothing is the first line of defense. Choosing the correct outfit ensures your session is both secure and effective.
Essential Features of Hyperbaric Chamber Garments
The ideal outfit prioritizes 100% natural fibers. Here’s what to look for:
Material: Pure cotton is the gold standard. It is breathable, comfortable, and non-static. Avoid any blends with polyester, nylon, or rayon.
Fit: Loose-fitting clothing is best. Tight garments can restrict circulation and become uncomfortable under pressure.
Layers: Chambers are often cool. Opt for layers like a cotton t-shirt under a cotton hoodie or button-up shirt for easy temperature regulation.
The Complete HBOT Clothing Checklist
Follow this checklist to prepare for your session:
• Top: A 100% cotton t-shirt, long-sleeve shirt, or sweatshirt.
• Bottom: Cotton sweatpants, loose-fitting trousers, or shorts. Avoid belts with metal buckles.
• Undergarments: Cotton underwear is mandatory. For more detailed guidance on every layer, see our dedicated resource on What To Wear In A Hyperbaric Chamber.
• Socks: Bring thick, cotton socks. The chamber floor can be cold.
• Hair: Use cotton hair ties. No metal clips or accessories.
Items to Absolutely Avoid in the Chamber
Your clinic will provide a list, but these are universal prohibitions:
• Synthetic Fabrics: No polyester, spandex, nylon, or fleece.
• Petroleum Products: This includes Vaseline, oil-based lotions, and certain cosmetics.
• Electronics & Metallic Items: Watches, jewelry, phones, and hearing aids must be removed.
• Flammable Items: Matches, lighters, or battery-operated devices are forbidden.
