hyperventilation

A breathing problem caused by too little carbon dioxide in the lungs. The term hyperventilation means overbreathing, where breathing is in excess of normal requirements of the body. This results in reducing the carbon dioxide (CO2) level of the body that provides the necessary stimulus for breathing. It is associated with anxiety and tension during flying. It can cause dizziness and may even lead to unconsciousness.
