Hyperventilation

Hyperventilation is breathing faster and more deeply than normal due to anxiety or stress. Breathing too quickly causes the carbon dioxide levels in the blood to fall quickly. The person feels like there is not enough air getting into his or her lungs and may complain of lightheadedness. Feeling the need for more air, the person breathes faster, making the symptoms worse.
