What are common symptoms of a diver's stress?

Rapid breathing and disorientation are indeed common symptoms of a diver experiencing stress. When a diver is under stress, whether from environmental factors, anxiety, or physical exertion, the body's response can lead to an increase in respiratory rate. This rapid breathing may also be accompanied by feelings of confusion or disorientation, making it difficult for the diver to think clearly and respond appropriately to their surroundings.

Understanding these symptoms is crucial for divers, as recognizing them early can help prevent further escalation of stress and potential diving accidents. Additionally, being aware of the body's signals allows divers to take appropriate actions, such as ascending to a shallower depth, practicing breathing techniques, or signaling to their buddy for assistance.

The other options describe scenarios that are either not typical indicators of stress or are not recognized symptoms in the context of diving. For instance, increased air consumption may relate more directly to physical exertion or equipment issues, while buoyancy changes and underwater vision problems do not specifically signify stress. Warmth and tranquility are more associated with a relaxed state rather than the stress response a diver experiences.
