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

Preparing for your first hyperbaric oxygen therapy (HBOT) session can bring up many questions, with one of the most common being: What Do You Wear In A Hyperbaric Chamber? The right attire is not about fashion—it’s a critical component of safety and comfort. This guide will walk you through everything you need to know.

Essential Safety Guidelines for Chamber Attire

Hyperbaric chambers are a controlled, high-pressure, oxygen-rich environment. To minimize fire risk and ensure equipment functions properly, strict clothing rules are enforced. The core principle is to wear 100% cotton garments. Synthetic materials like nylon, polyester, or rayon can generate static sparks, which are a significant hazard in an oxygen-rich atmosphere.

Choosing the Right Hyperbaric Chamber Garments

Your clinic will typically provide a suitable cotton gown or scrubs. If you are to bring your own, opt for loose-fitting, comfortable cotton clothing. Think along the lines of a cotton t-shirt and soft cotton sweatpants or shorts. Avoid any metal parts, including zippers, snaps, or underwires, as they can cause discomfort under pressure and pose a safety risk.

Comfort and Practicality During Your Session

Sessions can last 60 to 90 minutes, so comfort is key. The chamber’s temperature is regulated, but layers are a good idea. Since you cannot wear heavy clothing inside, consider bringing a cotton blanket offered by the facility to stay cozy. Remember, you will need to remove all external medical devices, jewelry, watches, and makeup or lotions before entering.

Items to Avoid for Hyperbaric Therapy

For absolute safety, you must avoid: hairspray or oil-based products, perfumes/colognes, hearing aids, dentures (partial or full), and contact lenses. These items can be damaged by the pressure or introduce contaminants. Your clinic will provide a complete checklist during your orientation.

Frequently Asked Questions (FAQ)

Q: Can I wear my own socks?

Q: What about underwear?
A: Yes, you can wear it, but it must also be made of 100% cotton with no metal parts.

Q: Why is cotton so important?
A: Cotton is a natural fiber that does not build up static electricity easily, making it the safest fabric choice in a high-oxygen environment where fire risk must be eliminated.
