THE MYTH BEHIND DEEP BREATHING

Traditional wisdom tells us that deep breathing is the best as it is thought to provide the most oxygen. We inhale oxygen and exhale carbon dioxide and the conclusion that is drawn is that oxygen is good for us and carbon dioxide is harmful. When Professor Buteyko was first analysing his patients he discovered that those who were sick breathed much more than those who were healthy; that is, their tidal volume, depth and frequency was greater. Could it be that "breathing deeply" is in fact contributing to ill health?

THE OXGYGEN PARADOX

In 1871 the Dutch doctor De Costa discovered the "Hyperventilation Syndrome" whereby deep breathing in a relaxed state caused dizziness and sometimes fainting. This is often incorrectly attributed to oxygen saturation. According to the Verigo-Bohr effect, it is the ratio of carbon dioxide to oxygen which permits the release or retention of oxygen from the blood.
