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

Preparing for your first hyperbaric oxygen therapy (HBOT) session? Knowing what to wear in a hyperbaric chamber is crucial for both your safety and comfort. This guide covers everything from essential fabrics to prohibited items, ensuring your experience is positive and effective.

Essential Clothing Guidelines for HBOT Safety

Safety is the top priority in the high-pressure, oxygen-rich environment of a hyperbaric chamber. Your clothing choices directly impact risk levels.

The Critical Role of 100% Cotton

Pure cotton is the gold standard. It’s naturally breathable, static-resistant, and doesn’t melt under heat—a vital fire safety feature in an oxygen-enriched atmosphere. Avoid synthetic blends like polyester or nylon, which can generate static sparks and are highly flammable.

Comfort and Fit Are Key

Choose loose-fitting garments. Tight clothing can restrict circulation, which is counterproductive to the therapy’s goal of enhancing blood flow. Comfortable, cotton pants and a roomy t-shirt are ideal. Most clinics will provide you with 100% cotton scrubs or gowns if needed.

What to Avoid: Prohibited Items and Materials

Certain items pose serious safety hazards and are strictly forbidden inside the chamber.

• No Synthetics or Wool: As mentioned, these materials are fire risks and can cause static discharge.
• No Makeup, Lotions, or Petroleum Products: These often contain oils or alcohol, which can be flammable. They also create a barrier that blocks oxygen absorption through your skin.
• No Jewelry, Watches, or Metal Objects: Metal can cause sparks (a ignition source) and may become uncomfortably hot during pressurization.
• Leave Electronics Outside: Devices like phones are not permitted due to spark risk and potential damage from pressure changes.

Frequently Asked Questions (FAQ)

Can I wear my own clothes?

Yes, if they are 100% cotton and loose-fitting. However, most facilities prefer you wear the provided hospital-grade cotton attire to guarantee safety compliance.

What about underwear?

Yes, but it must also be 100% cotton. Avoid any with metal wires or clasps.

Are glasses or hearing aids allowed?

Standard eyeglasses are usually permitted. Specialized, pressure-tolerant equipment may be allowed for hearing aids—always consult your chamber technician first.
