What can be a consequence of overstaying a dive without proper safety stops?

The consequence of overstaying a dive without proper safety stops is primarily the potential for decompression sickness. When a diver ascends too quickly or remains at depths longer than recommended, nitrogen absorbed by the body under pressure can form bubbles as pressure decreases during ascent. If a diver ascends without allowing these nitrogen bubbles to safely dissipate through controlled safety stops, it can lead to decompression sickness, a serious and potentially life-threatening condition. This emphasizes the importance of adhering to established dive tables, following ascent protocols, and implementing safety stops to allow the body to safely eliminate excess nitrogen.

The other options do not accurately represent the consequences of overstaying a dive without appropriate safety measures. Increased enjoyment of the underwater scene and improved lung capacity suggest positive outcomes, while decreased risk of equipment failure does not relate to the dive duration or safety stops. Understanding the risks associated with dive prolongation highlights the critical importance of safety in diving practices.
