What is the primary physiological benefit of lowering nitrogen absorption through Nitrox?

The primary physiological benefit of lowering nitrogen absorption through Nitrox is the reduced risk of decompression sickness. Nitrox, a mixture of nitrogen and oxygen with a higher percentage of oxygen than regular air, decreases the amount of nitrogen that divers absorb while they are submerged. As a result, when divers ascend to the surface, the reduced nitrogen saturation minimizes the chances of nitrogen bubbles forming in the body, which is a key factor in decompression sickness.

This condition can lead to serious health issues, so using Nitrox allows divers to extend their bottom time at certain depths without accumulating an excessive amount of nitrogen, thus promoting a safer diving experience. By mitigating nitrogen absorption, divers benefit from a more efficient and safer ascent, contributing significantly to overall dive safety.
