What is a benefit of following proper SIT times between dives?

Following proper Surface Interval Time (SIT) between dives is crucial for promoting body recovery and ensuring safety. When divers spend time on the surface between dives, their bodies have the opportunity to off-gas nitrogen that has accumulated during previous dives. This off-gassing process is vital for reducing the risk of decompression sickness, which can occur if divers ascend too quickly or if their bodies become oversaturated with nitrogen due to insufficient SIT.

During the SIT, the diver's body can also recuperate from the physical exertion of diving, restore energy levels, and reduce fatigue, which is especially important for maintaining focus and reaction times during subsequent dives. Overall, adhering to recommended SIT durations supports both physiological recovery and safety, enabling divers to enjoy their underwater experience while minimizing health risks associated with diving.
