The safest ascent rate to follow according to diving guidelines is 5 meters per minute. This rate is widely recommended by various diving organizations because it allows the body to adequately off-gas nitrogen, which has been absorbed during the dive. Ascending too quickly can lead to the formation of nitrogen bubbles in the bloodstream and tissues, increasing the risk of decompression sickness, also known as "the bends."

By adhering to a slower ascent rate, divers give their bodies sufficient time to equalize pressure and release nitrogen safely. This practice is especially crucial during safety stops, which are typically performed at around 5 meters (15 feet) after ascending for the last few meters of the dive. Following a controlled ascent and incorporating safety stops contributes significantly to the diver's overall safety and well-being.
