Deeper diving involves a range of specific risks and physiological considerations that are different from shallower dives. As divers descend deeper, they encounter increased pressure, which affects their bodies and the gases they breathe. For instance, the risk of nitrogen narcosis increases with depths greater than 30 meters (100 feet), and managing the effects of helium or oxygen at depth may require specialized knowledge and training in different gas mixes.

Trained divers are equipped to understand and handle these conditions, making it essential to have proper education and significant experience before attempting deeper dives. This training typically includes learning about gas management, buoyancy control, and emergency protocols that are crucial in deeper environments.

While recreational deep diving does take place, it is not regarded as a common practice for all divers, as there are significant safety considerations that must be addressed first. Additionally, deep diving is not suitable for all skill levels; beginners without the necessary training and experience may not be prepared for the complexities involved. Conducting dives at night is not a requirement associated with deeper diving, nor is it inherently suitable for all conditions and divers.
