What should divers do if they start to feel overwhelmed underwater?

The most appropriate action for divers who feel overwhelmed underwater is to signal their buddy and manage their breathing. This response is crucial because it emphasizes the importance of communication and teamwork in diving. When a diver feels overwhelmed, it may be due to various factors such as anxiety, equipment issues, or unfamiliar environments. By signaling their buddy, they can receive support and assistance, which can help alleviate the stress of the situation.

Managing breathing is equally important. Controlled breathing can reduce anxiety and improve focus, allowing divers to regain their composure. Deep, slow breaths help counteract the body’s natural stress response, promoting calmness. Together, these actions foster a safer diving experience, ensuring the diver can assess their situation and decide on subsequent actions without escalating the risk of panic or further complications.

The alternatives, such as ignoring the feeling or diving deeper, are unsafe choices that could exacerbate the situation or lead to dangerous consequences. Similarly, surfacing without signaling disregards the established protocols for safety and may put both the diver and their buddy at risk. Communication and managing one's physiological responses are critical in maintaining safety and minimizing stress while diving.
