Belly breathing is generally recommended over chest breathing because it allows for deeper, more efficient breathing. When you breathe into your belly, your diaphragm contracts and moves downward, allowing your lungs to fully expand and take in more oxygen. This type of breathing can help reduce stress and anxiety, as well as improve overall lung function. Chest breathing, on the other hand, is more shallow and can contribute to feelings of tension and anxiety. Therefore, practicing belly breathing can be beneficial for both physical and mental well-being. **

No, neon cannot be used as a breathing gas for diving. While neon has some advantages such as being less narcotic than nitrogen, it is not suitable for diving due to its low solubility in blood and tissues. This means that it would not effectively remove nitrogen from the body during ascent, increasing the risk of decompression sickness. As a result, neon is not used as a breathing gas for diving, and other gas mixtures such as nitrox or trimix are used instead. **
