About HBOT

What Is Hyperbaric Oxygen Therapy?

Hyperbaric oxygen therapy (HBOT) involves breathing oxygen inside a pressurized chamber at levels above normal atmospheric pressure. At Defiant, we operate a hard-shell multiplace chamber capable of up to 2.0 ATA — a non-invasive protocol designed to support your body’s natural repair processes.

Under gentle pressure, oxygen dissolves more efficiently into your blood plasma, reaching tissues and areas that may benefit from increased oxygenation. HBOT is used by athletes, biohackers, and individuals seeking support for recovery, cognitive clarity, and overall cellular health in Chicago’s western suburbs.

The Science

How HBOT Works

Oxygen Saturation

Under pressure, oxygen absorbs directly into your bloodstream — reaching tissues and cells that normal circulation often misses. It’s a more efficient delivery system than what your body can achieve on its own.

Cellular Repair

Healing happens at the cellular level, and cells need oxygen to do it well. HBOT increases oxygen availability throughout the body, supporting faster tissue regeneration and giving your cells the resources they need to repair.

Inflammation Response

Chronic inflammation slows recovery and keeps the body from healing properly. HBOT helps regulate the body’s inflammatory response — supporting your system’s natural ability to recover rather than stay in a prolonged stress state.

Recovery Support

Oxygen is central to how the body heals — from intense physical exertion to injury to post-surgical recovery. By significantly increasing oxygen saturation, HBOT helps accelerate the healing process and get you back to feeling like yourself sooner.

What to Expect

Your Session, Step by Step

Arrive & Check In

When you arrive at Defiant, our team will walk you through a brief intake, answer any questions, and make sure you feel comfortable before your session begins.

Enter the Chamber

You’ll step into a spacious pressurized chamber which is large enough for two people to sit comfortably, so you can bring a friend or family member if you’d like. Pressurization is gradual and gentle, similar to the ear pressure you feel on a plane. We’ll walk you through it.

Breathe & Relax

Once you’re at pressure, just breathe normally. Read, listen to music, meditate, sleep, whatever helps you unwind. Sessions run 30, 60, or 90 minutes, and many clients make it a regular part of their weekly routine.

Walk Out & Get On With Your Day

Depressurization takes just a few minutes. Most clients leave feeling clear-headed and energized. There is no downtime, no recovery period. Just back to your day.

FAQ

Common Questions

Everything you need to know about hyperbaric oxygen therapy at Defiant in Lisle, IL.

Hyperbaric oxygen therapy (HBOT) involves breathing oxygen inside a pressurized chamber. At Defiant, we use an OxyHealth 64D hard-shell chamber capable of up to 2.0 ATA, which may support tissue repair, reduce inflammation, and enhance overall recovery.

Hyperbaric therapy is widely considered safe and non-invasive. Some individuals experience temporary ear pressure, similar to the sensation during airplane takeoff. Our team walks you through equalization techniques before your first session.

Many clients notice benefits after a single session, though research suggests cumulative sessions may provide more sustained results. Our team can help you determine a frequency that aligns with your goals.

You may feel mild pressure in your ears during the initial pressurization, similar to ascending in an airplane. Once at pressure, most clients relax, read, or rest comfortably for the duration of the session.

Research suggests that hyperbaric oxygen therapy may support post-exercise recovery, modulate inflammatory pathways, and promote tissue repair. Many athletes and active individuals use HBOT as part of their recovery protocols.
