That is, a provisional imbalance in a particular part of the central nervous system. A condition that goes by itself. Fainting may occur under many conditions. The typical is that you fall on, or sink together without concomitant signs of pain or other discomfort. Some people experience before they pass out, some early warning symptoms appear such as dizziness, nausea, sweating or that it darkened the eyes. It may take from few seconds to several minutes before the actual fainting occurs. Others have no warning. During the fainting is breathing calm and slow.
