What to Wear in a Hyperbaric Chamber: Essential Clothing Guide for Safety and Comfort
When preparing for a hyperbaric oxygen therapy (HBOT) session, one of the most common questions patients ask is: What do you wear in a hyperbaric chamber? The answer is not just about comfort; it directly impacts safety during the high-pressure environment. In this guide, we’ll cover the essential clothing choices to ensure a secure and comfortable experience.
Understanding the unique conditions inside a hyperbaric chamber is crucial. The pressure changes can affect materials, while safety protocols strictly regulate what you can bring inside. Therefore, selecting the right attire is a critical first step before your therapy begins.
Why Clothing Matters in a Hyperbaric Chamber
The primary concern in a hyperbaric environment is fire safety. High oxygen levels inside the chamber dramatically increase the risk of fire. Any synthetic fabric—like polyester or nylon—can generate static electricity and ignite easily. To mitigate this, chambers require 100% cotton clothing. Cotton is breathable, static-free, and non-flammable under normal chamber conditions.
Additionally, certain materials like wool and silk are typically prohibited because they can also produce static sparks. Comfort is secondary to safety, but with proper selection, you can achieve both.

Recommended Attire for Comfort and Safety
Now that you know the why, let’s focus on the what. The best practice is to wear loose-fitting, 100% cotton clothing from head to toe. Here are the specific items suitable for a session:
Top: Cotton T-Shirt or Sweatshirt
Choose a simple cotton t-shirt or a cotton hoodie (without metal zippers). Avoid synthetic sportswear or fleece jackets. Cotton helps regulate body temperature as pressure changes can cause minor temperature fluctuations inside the chamber.
Bottom: Cotton Pants or Scrubs
Cotton yoga pants, sweatpants, or medical scrubs are ideal. Avoid denim with metal buttons or rivets because metal objects are typically not allowed. Ensure the fit is not too tight to restrict blood circulation, especially during longer sessions.
Footwear: Cotton Socks and Hospital Slippers
Most chambers require you to remove outdoor shoes. Wear clean cotton socks. Some facilities provide non-slip cotton socks or cotton slippers. Avoid leather or rubber shoes as they can trap heat and create static issues.
What to Avoid Completely
- Synthetics: Nylon, polyester, spandex.
- Metals: Jewelry, watches, bras with underwires, zippers.
- Makeup and Hair Products: Products containing alcohol, oil, or flammable chemicals.
- Electronics: Phones, smartwatches, hearing aids (unless specified).
