Oxygen is used to convert glucose into energy for all living cells, it is fundamentally important for energy production. We can go for weeks without food, days without water, but only minutes without oxygen.

Unfortunately breathing more air does not necessarily increase the amount of oxygen in the cells - it can have the opposite effect.

Due to the careful Ph balance of blood which controls oxygen release and carbon dioxide removal, people who breathe too frequently can find their oxygen becomes very tightly bound to the blood instead of being freely released into the cells. This long term lack of oxygen at a cellular level can result in low energy levels and disease.

Hypoxic training increases the sensitivity of the cell membrane and restores the normal release of oxygen from the blood.
