2. Common Symptoms

The symptoms commonly experienced during hyperventilation occur because of the restriction of blood to the brain. The person may be aware that their breathing has become too rapid. They are likely to feel light-headed and faint, and may also feel tingling sensations, especially in the fingers and hands. If it continues, the blood restriction to the brain may last long enough that the person loses consciousness. It is often accompanied by feelings of stress and anxiety.
