Let’s talk about oxygen.

At sea level, the air is 21% oxygen. The rest is mostly nitrogen. If you're in a city, you're also breathing pollutant gases like carbon monoxide.

Oxygen is kind of a big deal.

We need it to make ATP, our cellular energy currency.

ATP is made in our mitochondria, when oxygen accepts an electron from the electron transport chain, forming water and carbon dioxide in the process. Without oxygen, ATP stores drop quickly. Cell degeneration and death are not far behind.

Red blood cells (RBC) are the cells that carry oxygen throughout the body. Each RBC has hemoglobin molecules that bind to oxygen molecules from the air we breathe. In people with normal lungs, more than 97% of these hemoglobin sites are easily bound as RBCs pass through the lungs.

The ability for our body to carry oxygen where it's needed is called oxygen carrying capacity. If this oxygen carrying capacity is compromised, you can’t make enough energy... and this can lead to fatigue, brain fog, cold extremities, chronic infections, severe acute infections, and a host of other issues.

Here are two ways to increase oxygen carrying capacity:

1. Increase the number of RBCs in circulation. 

The more RBCs, the more hemoglobin sites to bind oxygen. The legal way to do this is by altitude training or simulating altitude in a HYPObaric environment, putting the body under hypoxic conditions that stimulate the natural hormone Epogen to be released to make more RBCs. The illegal ways to improve oxygen carrying capacity is via blood autotransfusion or exogenous Epogen administration. Remember Lance Armstrong? Blood doping = Exogenous Epogen!

2. Get more oxygen in circulation

The second way to increase oxygen carrying capacity is to diffuse more oxygen into the plasma or the liquid of the blood as unbound liquid oxygen.

Hyperbaric Oxygen Therapy (HBOT) is an effective way to diffuse more oxygen into the plasma via pressure.
