Which technique can help manage anxiety during a dive?

Deep breathing techniques are highly effective in managing anxiety during a dive because they help to activate the body's relaxation response. When a diver practices deep, controlled breathing, it can slow the heart rate, lower blood pressure, and promote a sense of calm. This approach counteracts the physiological symptoms of anxiety, such as increased heart rate and shallow breathing, which can exacerbate feelings of panic.

Furthermore, deep breathing allows for better oxygenation of the blood, which is crucial during a dive where physical exertion and stress can lead to hyperventilation and discomfort. By focusing on slow, deep breaths, divers can also redirect their attention from anxiety-inducing thoughts and concentrate on their surroundings and dive tasks, reinforcing their focus and confidence underwater.

In contrast to the other options, which may lead to increased anxiety or are not constructive approaches for managing such feelings during a dive, deep breathing provides a grounded method to help divers remain calm and in control.
