What Symptoms of hyperventilation may be averted by breathing into a paper bag because?

Breathing into a paper bag can help alleviate symptoms of hyperventilation, such as lightheadedness, tingling in the extremities, and shortness of breath. This technique works by increasing carbon dioxide levels in the bloodstream, which can counteract the respiratory alkalosis caused by rapid breathing. By restoring a more balanced carbon dioxide concentration, it can help calm the body's response and reduce anxiety associated with hyperventilation. However, this method should be used with caution and is not suitable for everyone; medical guidance is advisable.
