Which of the following is a common cause of stress for novice divers?

The common cause of stress for novice divers is indeed linked to a lack of experience and concerns related to their gear. Novice divers may feel overwhelmed by the unfamiliarity of the underwater environment, which can cause anxiety and stress. This is compounded by their potentially limited understanding of how their diving equipment functions, leading to fears about equipment failure or improper use. The combination of these feelings can create a heightened sense of stress, as they may lack the confidence to manage these issues effectively.

In contrast, experienced instructors tend to provide support and guidance, which usually alleviates stress rather than contributes to it. Likewise, familiar environments can enhance confidence and reduce stress, as novice divers are more at ease in settings they have practiced in or have a connection to. Lastly, while above-average physical fitness can be beneficial for divers, it does not inherently cause stress; rather, it may contribute to a sense of readiness and capability in the water.
