To alleviate the effects of overexertion while diving, resting and breathing deeply is essential. When a diver experiences overexertion, the body may become fatigued, and the rhythm of breathing can become irregular. Taking deep breaths helps to slow the respiratory rate, increases the oxygen supply to the muscles, and aids in recovery. Deep breathing exercises can also promote relaxation and help reduce heart rate, which is crucial for managing the body's response to stress and fatigue underwater.

In contrast, options that involve rapid breathing or stopping all movement do not effectively address the issue of fatigue. Rapid breathing can lead to hyperventilation, which disrupts the balance of oxygen and carbon dioxide in the blood, causing further complications. While stopping all movement might seem like a good way to rest, it does not promote adequate oxygen intake and may not address the body's overall need for recovery. Increasing physical activity would only exacerbate the situation and lead to more exhaustion, counteracting the goal of alleviating overexertion.
