Nitrox vs Regular Air: The Complete Comparison
Air vs Nitrox Diving Benefits
The Science Behind Nitrox Benefits
Nitrox contains 22-40% oxygen compared to regular air’s 21%, dramatically reducing nitrogen absorption. The most common Nitrox mix is 32 – 36 percent oxygen. This fundamental difference creates multiple advantages for divers exploring Koh Tao’s incredible marine life:
- Extended Bottom Time: Significantly longer no-decompression limits allow thorough site exploration
- Reduced Decompression Stress: Lower nitrogen loading decreases decompression sickness risk
- Clearer Thinking: Reduced nitrogen narcosis effects improve decision-making underwater
- Less Fatigue: Faster nitrogen elimination reduces post-dive exhaustion
- Multiple Dive Flexibility: Shorter surface intervals enable more dives per day
