What to Wear in a Hyperbaric Chamber: A Complete Safety & Comfort Guide

Entering a hyperbaric oxygen therapy (HBOT) chamber can raise many questions, with one of the most common being about proper attire. Choosing the right clothing is not just about comfort—it’s a critical safety requirement. This guide will walk you through everything you need to know to prepare for your session safely and comfortably.

Essential Guidelines for Hyperbaric Chamber Attire

The primary rule for hyperbaric chamber safety is to avoid any sources of ignition or static. Chambers are filled with pure, pressurized oxygen, making fire safety paramount. Therefore, your clothing must be 100% cotton. Synthetic materials like polyester, nylon, or rayon can generate static sparks, posing a severe risk. Most facilities will provide you with approved 100% cotton gowns or scrubs to wear during your treatment.

Comfort and Practicality During Treatment

Since sessions can last from 60 to 90 minutes, comfort is key. The provided cotton garments are designed to be loose-fitting and non-restrictive. Avoid belts, underwire bras, or any tight clothing. Remember, you will be lying down, so soft, breathable fabric is essential.

What to Avoid Wearing in the Chamber

Your pre-session preparation is just as important as what you wear inside. To ensure a safe environment, you must remove all potential hazards before entering.

Prohibited Items and Personal Products

Absolutely avoid bringing these items into the chamber:

• Makeup, Lotions, and Perfumes: These often contain petroleum-based ingredients or alcohols that are highly flammable in an oxygen-rich environment.
• Hair Products: Hairspray, oils, and gels are also fire hazards.
• Jewelry and Watches: Metal can cause sparks and may become uncomfortably warm.
• Electronic Devices: Phones, tablets, or any battery-operated devices are not permitted.
• Hairpins/Metal Clips: These can pose both a spark risk and a comfort issue.

Frequently Asked Questions (FAQ)

Can I wear my own cotton clothes?

Often, yes. Many centers allow patients to wear their own 100% cotton clothing (like a t-shirt and sweatpants) if it is clean, loose-fitting, and approved by the technician. Always check with your specific facility first.

What about footwear?
You will typically be provided with cotton socks or slippers. Outdoor shoes are never worn inside the chamber to maintain cleanliness and safety.

Is it cold inside the chamber?
The temperature is regulated for comfort, but the compression phase can feel warm, and decompression can feel cool. The cotton gown allows for good temperature regulation.
