What is the consequence of exceeding the dive time at depth?

Exceeding the dive time at depth primarily increases the risk of decompression sickness. This condition, also known as "the bends," occurs when a diver ascends too quickly after spending too long at depth. As pressure decreases, nitrogen absorbed by the body due to the increased ambient pressure during the dive can form bubbles in the tissues and bloodstream. These bubbles can lead to serious health issues, including joint pain, neurological problems, and even potentially fatal outcomes if not properly addressed.

This understanding emphasizes the importance of adhering to established dive tables or dive computer recommendations, which are designed to keep divers within safe limits to avoid such risks. Managing time at depth not only ensures the physical safety of the diver but also enhances the overall experience by allowing for adequate decompression and minimizing health concerns.
