Which behavior can contribute to causing hyperventilation?

Feeling anxious and breathing rapidly is a significant contributor to hyperventilation. When a person experiences anxiety, the body's natural response is to prepare for a perceived threat, often leading to rapid, shallow breathing. This quickened breathing can decrease carbon dioxide levels in the blood, causing symptoms such as lightheadedness, tingling in the extremities, and sometimes even chest discomfort.

Understanding the connection between anxiety and breathing patterns is crucial, particularly in aviation settings, where high-stress situations can trigger such responses. Recognizing that hyperventilation often stems from emotional or psychological states emphasizes the importance of managing stress and anxiety for maintaining optimal performance and safety.

In contrast, practices like meditation, regular exercise, and controlled breathing techniques often promote relaxation and can help regulate breath instead of causing hyperventilation. Therefore, D accurately identifies a behavior that directly leads to hyperventilation.
