Which of the following is a symptom of cold shock?

Rapid, uncontrolled breathing is a key symptom of cold shock. This physiological response occurs when an individual's body is suddenly exposed to cold water. The initial impact of cold water can cause the body to instinctively gasp or hyperventilate, leading to difficulty in breathing and a rapid heart rate. This reaction can be dangerous, especially if the person is submerged in water, as it may lead to aspiration or panic, further complicating the situation.

Recognizing this symptom is crucial for anyone involved in boating or water activities, as it signals the body's immediate response to a sudden temperature drop. Understanding that cold shock can provoke uncontrollable breathing helps individuals to be aware of their body's reactions and to take appropriate safety measures.
