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 should I wear? The right attire is not about fashion—it’s a critical component of safety and comfort during treatment. This guide will walk you through everything you need to know to dress appropriately for the pressurized environment of a hyperbaric chamber.

Essential Clothing Guidelines for HBOT Safety

Safety is the paramount concern inside a hyperbaric chamber. The high-oxygen environment is highly flammable, making fabric choice your first priority. All clinics will provide you with 100% cotton garments, as synthetic materials like nylon, polyester, or rayon can generate static sparks and are strictly prohibited. You will change into these provided scrubs or gowns before your session. Avoid using hairspray, lotions, or petroleum-based products on your skin or hair, as these can also be fire hazards.

Choosing Comfortable and Non-Restrictive Attire

Even though you’ll change, what you wear to the clinic matters. Opt for loose, comfortable clothing that is easy to change in and out of. This is especially important for patients with mobility challenges. Comfortable shoes are also recommended. Remember, you’ll be lying down for an extended period, so avoid belts, tight waistbands, or complicated outfits.

What Personal Items Are Allowed?

Personal items are severely restricted. You cannot wear watches, jewelry, hearing aids, or any electronic devices into the chamber. Dentures and glasses are typically allowed but must be reported to the technician. For a comprehensive list of approved and prohibited items, you can consult this detailed resource on What To Wear In A Hyperbaric Chamber.

Managing Temperature and Sensory Comfort

Chamber temperatures can vary. The provided cotton garments help with temperature regulation. If you tend to get cold, ask the facility if they provide blankets (always cotton). Communicating any discomfort to your technician is key, as they can often adjust the chamber’s temperature or ventilation for your comfort.

Frequently Asked Questions (FAQ)

Can I wear my own 100% cotton clothes?

Most facilities insist you wear their provided, specially laundered scrubs to ensure no contaminants or synthetic residues are introduced into the pure oxygen environment.

What about underwear?
Yes, you can wear your own 100% cotton underwear. For women, a cotton sports bra without an underwire is often the most comfortable and safe option.

How should I do my hair?
Avoid any metal hair clips, pins, or ties with metal parts. Use a simple cotton or fabric hair tie if needed.
