What is a "safety stop" in diving?

A "safety stop" in diving is an optional pause during ascent to help reduce the risk of decompression sickness. This practice involves stopping for a few minutes at a depth typically around 5 meters (15 feet) for recreational divers after completing a dive. The primary purpose of this stop is to allow nitrogen absorbed by the body tissues to be released more safely, which can help mitigate the risk of nitrogen bubbles forming as a diver ascends to the surface.

While a safety stop is not a mandatory requirement for all dives, it is highly recommended, especially for deeper dives or longer bottom times. This precaution also gives divers a moment to reflect on their dive and observe marine life, contributing to overall safety and enjoyment.

The other options don't accurately describe the function or purpose of a safety stop. For instance, reflecting on experiences or gathering equipment does not directly relate to safety in terms of physiological effects as divers ascend. Similarly, checking dive instruments during ascent is more of an operational procedure rather than a specific safety stop aimed at preventing decompression sickness.
