Breathing is something most of us don’t usually think about. If we’re still alive and breathing, we must be doing it right, right? Wrong.
Let’s start with the disadvantages of rapid, upper chest breathing. Things I see in my physical therapy practice every day. Like neck pain, low back pain, anxiety, poor sleep, cold hands and feet. And headaches. Especially headaches. In all my years of practice, I have never, not once, met someone suffering from headaches who breathed well. (Most of my clients with headaches have a similar story: headaches for years, poor sleep, cold hands and feet, tight neck muscles–all related to upper chest breathing).
Let’s get to the good news…
What are the advantages of breathing well, that is, slow, diaphragmatic breathing? There are SO many advantages that I can’t even begin to list– much less describe– them all here. Let’s start with three important ways breathing well is related to feeling well, as in, less pain.
Diaphragmatic breathing promotes the relaxation response. One of the the ways it does this is by activating the vagus nerve (which lies close to the diaphragm, so when we breathe deeply and the diaphragm moves up and down, the vagus nerve is stimulated). 75% of the parasympathetic (rest and repair) nervous systems’s fibers come from the vagus nerve, so the vagus nerve is a VERY big player in the relaxation response. So much so, that slow, deep breathing is one of the most efficient, non-medication ways we have of going from the state of “fight or flight” (where most of us tend to hang out) to the much more healthy “rest and repair.” When our bodies are in a relaxed state our brains are considerably less likely to perceive input as threatening, and so pain signals are significantly turned down. Research has shown that decreasing anxiety can decrease a pain level of 7/10 to 3/10. Definitely significant.
Diaphragmatic breathing also improves oxygenation. Of course it does. Seems obvious. But did you know that the lower parts of our lungs are about 7 times more productive in oxygen transport than the higher parts? So when we breathe using our diaphragms (and thus the lower lobes), we get much more oxygen to all of our cells, including the cells in our hands and feet (they’re warmer–a nice fringe benefit), and our nerve cells (less pain). And all healthy cells need oxygen. Only pathogens (unhealthy cells) don’t.
Lastly, diaphragmatic breathing stimulates lymphatic drainage. Our lymphatic system has been compared to a sewage system (yuck!). It removes toxins, wastes and abnormal cells. The lymphatic system doesn’t have any pumps, so it relies on muscle contraction and deep breathing to keep it moving. Using our diaphragms to breathe stimulates the cleansing of lymph nodes, increasing lymphatic drainage. This increases the rate of toxin elimination (including the byproducts of inflammation, which cause pain) by as much as 15 times!
