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. Your comfort and, more importantly, your safety are paramount. A crucial part of your preparation is knowing exactly what to wear in a hyperbaric chamber. This guide will walk you through the essential do’s and don’ts to ensure a safe, comfortable, and effective treatment session.

The Golden Rule: Safety First in Hyperbaric Environments

The primary concern inside a pressurized chamber is fire risk. Pure oxygen environments are highly flammable. Therefore, all clothing choices must prioritize materials that minimize static electricity and combustion risk.

Choosing the Right Fabric for Chamber Safety

Always opt for 100% cotton garments. Cotton is naturally breathable, soft, and, most critically, anti-static. Avoid all synthetic materials like polyester, nylon, or rayon, as they can generate static sparks and are more prone to melting.

The clinic will provide you with a specialized hyperbaric chamber gown or suit made from approved fire-retardant fabric. You will wear this over your approved cotton base layer.

Your Step-by-Step Attire Checklist

Follow this simple checklist to prepare for your session:

✅ DO WEAR: A 100% cotton t-shirt and loose-fitting cotton pants or shorts. Cotton socks are also recommended. Simple cotton underwear is essential.

❌ DO NOT WEAR: Any makeup, lotions, perfumes, or petroleum-based products. Remove all jewelry, watches, and hair accessories. Avoid hairspray or gels. Do not bring electronics, lighters, or any metallic objects into the chamber.

Managing Comfort During Your HBOT Session

Treatments can last 60 to 90 minutes. Wear loose-fitting cotton clothes to allow for easy circulation and to feel relaxed. The chamber temperature is regulated, but layers are not advisable under the provided gown. Your comfort is key to a restful session.

Frequently Asked Questions (FAQ)

Can I wear my own clothes?
You will wear your approved cotton base layer, but a clinic-provided gown or suit must be worn over it for maximum safety compliance.

Why is cotton mandatory?
Cotton’s natural properties prevent static buildup, significantly reducing any fire hazard in the oxygen-rich environment.

What about glasses or hearing aids?
Consult your technician. Special arrangements can often be made for medically necessary devices approved for hyperbaric use.
