What should divers do to ensure safe ascents?

To ensure safe ascents, divers should use a slow, controlled ascent rate. This practice is crucial because it helps to reduce the risk of decompression sickness, commonly known as "the bends." When divers ascend too quickly, the rapid decrease in pressure can cause dissolved gases in the body, primarily nitrogen, to come out of solution too quickly, forming bubbles and leading to potential injuries.

A controlled ascent allows divers to manage their ascent, often integrating safety stops at certain depths to allow excess nitrogen to safely be expelled from their bodies. This method promotes gradual equalization of pressure and helps ensure that divers can ascend safely without complications. Following recommended ascent rates—commonly regarded as no faster than 10 meters (about 33 feet) per minute—further supports this safety measure.

In summary, maintaining a slow, controlled ascent rate during dives is essential to promote safety and minimize the risk of decompression-related issues.
