BreatheFeb. 26, 2006: Hyperventilation increases your body's pH
Why all this fuss about breathing? Why should we care about how we breathe? Because poor breathing strategies have real health consequences on a physical and a psychological level, and we tend to breathe rather often. It is not like we can decide to stop breathing for a while, so changing to a more optimal breathing pattern can have a huge impact on the ease with which we live in our bodies.
Over breathing, or chronic hyperventilating is a very common breathing pattern that can have many significant consequences. Hyperventilation causes a loss of carbon dioxide from our body which makes the blood more alkaline. In this alkaline environment our hemoglobin, which are the buses that carry the oxygen that we breathe, now has a harder time releasing the oxygen to the cells. As a result, the cells get less oxygen, and through feedback loops, the body signals a need for more air, so the person breathes more frequently, which usually leads to more loss of CO2. The alkaline environment also causes more calcium to enter the muscles and nerve tissue, making them more excitable than they should be, and causes the arteries of the brain, heart and body to constrict, which means reduced blood flow to these tissues. Symptoms of hyperventilation include headaches, chronic muscle tension, chest tightness, cold hands and feet, digestive issues, dizziness, lack of ability to concentrate, irritability, shortness of breath, anxiety, fatigue and even low back or pelvic pain, as when the breath isn't right, the other deep core stabilizer muscles have difficulty controlling the movement of the vertebrae and pelvis. (Some medical conditions such as diabetes or kidney disease may result in an acid environment, so hyperventilation may be the body's way of trying to rebalance the blood pH).
Some hints that you may be hyperventilating include chest breathing, (place one hand on the chest and one on the side of the ribs - does the chest hand move more than the rib hand?), breathing more than 15 times per minute, breathing frequently through the mouth, using your abdominal muscles to force the air out of the lungs so that another breath can be taken quickly, not pausing after the inhale or the exhale, very shallow breathing that is more like the flutter of a butterfly wing than the slow rhythmical strokes of an eagle.
A good place to begin correcting this breathing pattern is to do the exercise mentioned in an earlier tip of placing the hands around the lower ribcage and directing a normal size breath of air deep into the pelvis, relaxing the abdominals and feeling the lower ribs expand all around slightly, and then allowing the air to slowly come out all by itself. Notice if you are breathing quickly and actively slow it down by getting the air lower into the lungs. Try to slow down your life - stop rushing about, and slow down your thinking, planning, worrying, mental rehearsing. Physical, mental and emotional hurrying are linked to hurrying the breath.
