Why divers have had problems in concentrating underwater?

Divers often experience concentration issues underwater due to factors such as increased stress, anxiety, and the environment's sensory overload. The pressure change can affect cognitive function, while the need to constantly monitor equipment and surroundings can lead to distraction. Additionally, physical exertion and the cold water can contribute to fatigue, further impairing focus. These elements combined can make it challenging for divers to maintain clear and effective concentration during their dives.
