If you are preparing for a medical or wellness session in a hyperbaric chamber, one of the first questions that likely comes to mind is, What Do You Wear In A Hyperbaric Chamber? Unlike typical medical appointments, the clothing requirements here are specific and non-negotiable for safety and efficacy. The primary rule is that you must wear 100% cotton or other fire-resistant fabrics. Synthetics like polyester or nylon are strictly prohibited because they can generate static electricity, which is a fire hazard in the oxygen-rich environment of the chamber. Understanding these guidelines is the first step toward a safe and comfortable treatment experience, so let’s break down the essential clothing choices and why they matter.

Core Clothing Guidelines for Hyperbaric Chambers

When asking What Do You Wear In A Hyperbaric Chamber, the answer always starts with the material. Medical-grade cotton scrub suits are the gold standard for therapy because they are free from synthetic blends. Many facilities will provide a clean cotton gown or scrubs for you to change into. If you are using a monoplace (single-person) chamber, you will usually wear a light cotton gown. For multiplace chambers, which accommodate several people, you might wear a full cotton scrub set. Button-down tops are often preferred because they are easy to remove in an emergency. It is also crucial to remove any accessories, including jewelry, watches, and even hairpins, as these can cause burns or pressure injuries. Additionally, take off contact lenses, dentures, or hearing aids, as pressure changes can damage them or cause discomfort.

Why Cotton is the Only Safe Fabric

To fully grasp What Do You Wear In A Hyperbaric Chamber, you need to understand the science behind the material restrictions. The chamber is pressurized to levels equivalent to deep-sea diving, and you breathe pure oxygen. This creates a highly combustible environment. Synthetic fabrics like polyester, spandet, or acrylic can create sparks through static discharge. Even a single spark in this oxygen-rich atmosphere can lead to a catastrophic fire. Cotton, on the other hand, is naturally static-resistant and less likely to catch fire. Therefore, your clothing must be a consistent 100% cotton—this includes your socks, t-shirt, sweatpants, or leggings. Baggy or loose-fitting clothing is also discouraged as it can compress or fold in ways that cause skin irritation or pressure areas during the dive.

Footwear and Socks: What About Your Legs and Feet?

The question, What Do You Wear In A Hyperbaric Chamber, extends to your feet. You will rarely wear shoes inside the chamber. Instead, you typically wear cotton socks or go in barefoot with a non-skid cotton slipper. Shoes are often made of synthetic materials and can hold moisture or debris. If you are in a walk-in multiplace chamber, you might wear specialized anti-static slippers provided by the facility. For your legs, wear loose-fitting cotton pants or shorts. Avoid leggings or tight jeans even if they are labeled as cotton, as the tight weave and seams can create pressure points, leading to discomfort during the standard 60-90 minute dive. Remember, comfort and safety are intrinsically linked when considering What Do You Wear In A Hyperbaric Chamber.

Can I wear headphones or earplugs? Yes, but they must be provided by the facility. Pressure changes affect eardrums, so you will use special foam earplugs or sound-dampening headphones. Do not bring
