What is one of the primary risks of ascending too quickly in a cavern?

Ascending too quickly in a cavern poses a significant risk of decompression sickness, also known as "the bends." This condition arises due to the rapid release of dissolved nitrogen from the body's tissues as a diver ascends. Under pressure, such as when diving, nitrogen gas is absorbed into the body. If a diver surfaces too quickly, the decrease in pressure can cause nitrogen bubbles to form in the bloodstream and tissue, leading to a variety of symptoms ranging from joint pain and fatigue to more severe neurological issues and potentially life-threatening conditions.

The bubbles can obstruct blood flow and cause inflammation, leading to complications that may require medical attention. Proper ascent rates and safety stops are crucial for allowing nitrogen to safely off-gas and reduce the risk of decompression sickness, making this consideration essential for safe cavern diving.
