Which condition may worsen due to underwater stress?

Underwater stress can significantly impact a diver's ability to make sound decisions. Stress may arise from various factors such as difficult environmental conditions, unexpected equipment issues, or any situation that might provoke anxiety. When a diver is under stress, their cognitive functions can become impaired, leading to slower reaction times, a narrowed focus, and potential confusion. This can ultimately affect the diver's ability to assess situations properly, prioritize tasks, and respond effectively to challenges encountered underwater.

In a diving context, poor decision-making can have serious consequences, such as mismanaging air supply, failing to monitor depth, or not recognizing the need to ascend in a timely manner. Therefore, the ability to make clear decisions is crucial for ensuring safety while diving.
