What is considered a safe ascent rate for divers after completing a dive?

The safe ascent rate for divers after completing a dive is typically recognized as 5 metres per minute. This rate minimizes the risk of decompression sickness, also known as "the bends," which can occur when a diver ascends too quickly. During ascent, the pressure around a diver decreases, which can cause dissolved gases in the body (primarily nitrogen) to form bubbles if the ascent is too rapid. Adhering to a slower ascent rate allows the body time to safely eliminate the excess nitrogen through the lungs without forming harmful bubbles in the tissues or bloodstream.

Additionally, following the recommended ascent rate includes safety stops at specific depths, often around 5 metres for recreational diving, to further reduce the risk of decompression sickness. Maintaining a disciplined and cautious ascent helps ensure that divers minimize their risk while enjoying safe recreational diving experiences.
