# What to Wear in a Hyperbaric Chamber: The 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 prohibited fabrics to the ideal attire, ensuring your experience is positive and effective.
## **Why Your Chamber Attire Matters**
Your clothing choice directly impacts safety and treatment efficacy. Inside the pressurized environment, certain materials can pose fire risks or interfere with oxygen circulation. The right outfit promotes relaxation, allowing your body to fully benefit from the increased oxygen levels.
### **The Golden Rule: 100% Cotton**
Most facilities mandate 100% cotton garments. Why? Cotton is naturally breathable, static-resistant, and less likely to spark compared to synthetic fibers. Avoid blends, polyester, nylon, or wool, as these can generate static electricity and are potential ignition sources in an oxygen-rich atmosphere.
### **What to Wear: The Complete Checklist**
* **Top:** A loose-fitting, 100% cotton t-shirt or hospital gown provided by the facility.
* **Bottoms:** Cotton sweatpants or shorts. Avoid tight jeans or leggings.
* **Underwear:** Must also be 100% cotton.
* **Socks:** Cotton socks are often required to protect the chamber’s interior.
* **Hair:** Remove oil-based products. Use cotton hair ties if needed.
* **Skin:** No lotions, oils, perfumes, or petroleum-based products. They are flammable.
## **What NOT to Wear in the Chamber**
Your safety depends on avoiding these items:
* **Synthetics:** Polyester, rayon, spandex, nylon.
* **Flammables:** Hairspray, makeup, deodorant (non-cotton roll-ons).
* **Jewelry/Metal:** Watches, rings, piercings. Metal can overheat.
* **Electronics:** Phones, smartwatches, hearing aids (unless approved).
* **External Medical Devices:** Consult your technician.
## **FAQs on Hyperbaric Chamber Attire**
**Can I wear my own clothes?**
Yes, if they are 100% cotton and approved by the technician. Most centers provide approved gowns.
**Why is static electricity so dangerous?**
In a high-oxygen environment, a static spark can ignite materials rapidly, creating a severe fire hazard.
**What if I get cold?**
The chamber temperature is controlled. Facilities provide cotton blankets—never synthetic ones.
**Are wipes or sanitizers allowed?**
No. Alcohol-based products are highly flammable under pressure.
