What might happen if you exceed the recommended depth or duration of a dive?

Exceeding the recommended depth or duration of a dive can lead to nitrogen retention, which may necessitate making decompression stops during ascent. When divers descend beyond the limits of their training or the specific guidelines for the gas mix they are using, they can absorb more nitrogen than their bodies can safely eliminate on ascent. Over time and at certain depths, nitrogen can accumulate in body tissues, increasing the risk of decompression sickness, commonly known as "the bends." Decompression stops are critical for allowing nitrogen to safely off-gas from the body gradually, preventing the formation of harmful bubbles in the bloodstream or tissues. Adhering to depth and time limits is essential for ensuring diver safety and minimizing decompression risks.
