What is one of the signs of hyperventilation?

1. Over breathing

2. Decreased heart rate

3. Cold extremities

4. Extreme fatigue

The correct answer is: Over breathing

Over breathing is a key sign of hyperventilation. During hyperventilation, an individual breathes at an abnormally rapid rate, leading to excessive expulsion of carbon dioxide from the body. This excessive breathing can cause a range of symptoms, such as lightheadedness, tingling in the extremities, and shortness of breath, all of which stem from the sudden shift in the body's carbon dioxide levels due to over breathing. Recognizing over breathing as a primary indicator of hyperventilation is crucial for understanding the physiological changes that occur during this condition. In contrast, options like decreased heart rate, cold extremities, and extreme fatigue may relate to other health issues but do not directly characterize hyperventilation. Typically, hyperventilation is associated with an increased heart rate and may lead to feelings of panic or anxiety rather than fatigue.
