During which phase of diving stress recovery should a diver focus on controlled breathing?

Focusing on controlled breathing during the stress recovery phase is crucial when a diver is under stress during the dive. This is because stress can lead to physiological and psychological reactions, such as increased heart rate and panic, which can adversely affect a diver's ability to think clearly and make sound decisions. By concentrating on controlled breathing, the diver can help regulate their heart rate, reduce anxiety, and restore a sense of calmness. Controlled breathing techniques, such as slow, deep inhalations followed by longer exhalations, can facilitate relaxation and improve focus, allowing the diver to regain composure and manage the situation more effectively.

Practicing controlled breathing in other phases, such as before entering the water or during ascent, is beneficial for overall relaxation and preparation but is especially critical when experiencing immediate stress underwater. At that moment, the diver's ability to manage their breathing can significantly impact their response to the stressor and the effectiveness of their rescue or recovery actions.
