Important: Read This Before Your Hyperbaric Oxygen Therapy

Hyperbaric oxygen therapy (HBOT) has moved far beyond its niche origins. What was once reserved for divers dealing with decompression sickness is now a feature in premium clinics, forward-thinking wellness spaces, and even private households.

But here’s the thing: HBOT isn’t just about stepping into a hyperbaric chamber and letting oxygen do the work. Preparation plays a quiet but powerful role in how the experience unfolds.

So, how do you actually prepare for HBOT—whether you own a home-based HBOT chamber or are about to begin sessions at a clinic?

Let’s break it down.

How To Prepare For Hyperbaric Oxygen Therapy?

1. Hydration

Proper fluid levels support circulation, which in turn helps your body distribute oxygen more efficiently.

Drink water consistently in the 24 hours leading up to your session.
Limit excessive caffeine or alcohol, as both can dehydrate.

2. Eat Light, But Don’t Go In Fasting

Optimize your HBOT experience by arriving neither too full nor too hungry. A light meal helps you stay comfortable under pressure while maintaining steady energy levels throughout the treatment.

Timing: A light, balanced meal about 1–2 hours before your session works best.
Focus on: Lean protein, healthy fats, and low-glycemic foods.

3. Avoid Certain Products

Because a hyperbaric oxygen chamber involves a high-oxygen environment, safety protocols are strict. Avoid:

Alcohol-based products: Perfumes or sprays, as these can be combustible in high-oxygen environments.
Synthetic clothing: 100% cotton garments are typically recommended to prevent static electricity.

4. Manage Congestion and Sinus Pressure

HBOT involves pressure changes similar to those felt during a flight descent. If you are congested or have blocked sinuses, this pressure can make the session uncomfortable.

Use a saline nasal spray if needed.
Avoid sessions when dealing with active sinus infections.
Practice simple ear equalization techniques like swallowing or yawning.

5. Medications

Before starting HBOT, it’s important to review any medications you’re taking.

Medical Clearance: Some treatments or drugs may require adjustment or medical clearance. This includes certain chemotherapy agents or respiratory-related medications.
Consultation: Clinics typically cover this during onboarding. If you are using a home-based setup, we highly recommend consulting a qualified professional first.
