In this video I’m sharing my first ever step into “biohacking” while I was in Thailand: I tested a hyperbaric oxygen chamber (the O2 Fresh M50). It honestly looks like a sunbed, but the idea behind it is pressure + science to help your body recover. I break down what a hyperbaric chamber is in simple terms, including the pressure difference (sea level is about 101.3 kPa, and this chamber was set around 20 kPa above that), and why higher pressure can push more oxygen deeper into your tissues. Here’s the part that surprised me: the chamber I tried didn’t use 100% pure oxygen like the “real” medical-style HBOT you hear about. It was pressurized regular air, so I talk about how that still increases oxygen absorption and why athletes and biohackers chase it for recovery, inflammation reduction, and overall wellness. I also mention how celebrities and athletes use these chambers (Justin Bieber, Cristiano Ronaldo) and why the trend is growing. My honest experience: the pressure change feels like a plane taking off (ears feel weird), but swallowing and staying calm helps. After 30 minutes I felt lighter and more relaxed, and weirdly my vision felt better for the rest of the day. I also admit I felt a little scammed because I expected pure oxygen—so I want you to understand what you’re paying for before you book a session.
