What is one reason divers choose to use Enriched Air Nitrox over regular air?

Divers often choose to use Enriched Air Nitrox because it reduces fatigue during and after dives. The primary reason for this is that Nitrox contains a higher percentage of oxygen compared to regular air, which has about 21% oxygen and 79% nitrogen. By using a gas mixture with a higher proportion of oxygen, divers can experience less nitrogen absorption in their bodies.

Lower nitrogen absorption is beneficial as nitrogen is the gas that contributes to decompression sickness or "the bends." Reducing nitrogen exposure leads to shorter surface intervals and a decreased likelihood of fatigue or other post-dive issues. Divers often report feeling less tired after using Nitrox compared to standard air, which can enhance the overall diving experience and allow for more activities and enjoyment after the dive.

In contrast, while easier to breathe, deeper dives, or less water vapor in Nitrox are considerations, they do not directly correlate with the primary reason divers adopt Nitrox for reducing fatigue. Thus, the unique benefit of reduced fatigue stands out as a compelling reason for choosing Enriched Air Nitrox.
