Breathing is an important factor for the body being “on”—active rather than at rest. Van der Poel links this to a disrupted balance between oxygen and carbon dioxide in the blood. According to her research, a shortage of carbon dioxide in the blood raises the pH value. The carbon dioxide shortage is caused by breathing too rapidly or too deeply, which brings us back to Konstantin Buteyko and his ideas about asthma. The breathing exercises and the possibility of mobilizing brown fat as a fuel can also have beneficial effects for people suffering from fatigue.
