| Wiki: | Hyperventilation (or overbreathing) is the state of breathing faster and/or deeper than normal. It can result from a psychological state such as a panic attack, from a physiological condition such as metabolic acidosis, or can be brought about voluntarily. Hyperventilation can, but does not necessarily always cause symptoms such as numbness or tingling in the hands, feet and lips, lightheadedness, dizziness, headache, chest pain, slurred speech, nervous laughter, and sometimes fainting, particularly when accompanied by the Valsalva maneuver. |
