TDI Cavern Diver Practice Exam 2025 – Complete Prep Guide

Self-awareness pertains to an individual's understanding and recognition of their own body and mind. This includes an awareness of one’s emotions, thoughts, sensations, and physical state. In the context of diving, having self-awareness enables a diver to recognize how they are feeling both physically and mentally, which is crucial for assessing their readiness to dive and their ability to respond to challenges effectively under water.

In contrast to self-awareness, global awareness involves an overarching understanding of how various systems and environments interconnect, while situational awareness refers to understanding the context and dynamics around oneself in a specific environment. Environmental awareness focuses specifically on the external surroundings, including potential hazards and the natural conditions present. Therefore, while each of these types of awareness is important in diving, self-awareness is uniquely concerned with the individual’s introspection and knowledge of their own internal state.
