What should a diver experiencing panic do to regain control?

When a diver experiences panic, the most effective way to regain control is to stop, rest, and breathe slowly and deeply. This method helps to calm both the mind and body, which can often lead to clearer thinking and a more focused approach to resolving the situation. Panic can lead to rapid, inefficient breathing and poor decision-making, potentially exacerbating the situation. By intentionally slowing down and concentrating on steady, deep breaths, the diver can reduce physiological stress responses, lower heart rate, and foster a sense of reassurance and control.

The other options may introduce additional risks or not address the immediate need for calmness. Swimming rapidly to the surface can lead to dangerous situations such as decompression sickness or barotrauma due to rapid ascent. Using an emergency buoy may not be effective in regaining composure and could be unnecessary in situations where the diver feels overwhelmed but still has enough time and air to safely manage their ascent. Calling for help may also be inappropriate if the situation is manageable, as it shifts focus from personal control to relying on others, which can be counterproductive in a moment of panic.
