The Benefits of Mindful Breathing

Our breath sustains us. It not only supplies our cells with life-giving oxygen, the mechanical act of breathing itself is intimately connected to our body’s basic physiology. With every breath in our heart rate increases and with every breath out it slows.

The modulation of respirations, heart rate, blood pressure and digestion are interconnected through the primitive part of the brain called the brainstem and primitive nervous system called the autonomic nervous system. Most of the autonomic nervous system functions are unconsciously controlled. The distinguishing feature of the breath, however, is that we have conscious control over the speed, depth and flow of our breathing. And, by consciously controlling our breath, we can have far reaching positive effects on other aspects of our autonomic nervous system physiology and our response to stress.

The autonomic nervous system acts like a switch. It is either in ‘rest and digest’ mode or ‘fight or flight’ mode. Consciously slowing and deepening your breathing will ‘flip the switch’ and take you from ‘fight or flight’ to ‘rest and digest’ by slowing your heart rate, decreasing your blood pressure, improving your digestion and calming your mind.

The stress response and breathing are hard-wired in our nervous system. Someone who has trouble breathing will naturally panic just as someone who has a panic attack will naturally feel short of breath.

Did you ever catch yourself holding your breath during a stressful situation? Most of us spend a good deal of the day with shallow chest breathing and when times get stressful we may even unconsciously hold our breath. It follows that shallow chest breathing and breath holding are associated with increased blood pressure, heart rate and anxiety, while the opposite, deep belly breathing, is associated with decreased blood pressure and heart rate, reduced pain and a calm state of mind.

Ancient practitioners of yoga knew that the quality of breath dictates our state of mind. As Westerners, we are just catching up to this. Breathing techniques that slow the breath, concentrating on prolonging the exhale, change brain waves to the alpha rhythm which is a rhythm correlated with relaxation, positive mood and a reduction in the stress hormone, cortisol (1). It follows that breathing exercises are useful in the management of chronic pain (2). And learning to regulate the breath can even decrease performance anxiety and improve work performance in children (3).

Your breath is free, travels with you, and can be used as a tool anywhere and anytime to calm and elevate your mood and bring you to the present moment. Practice slowing and deepening your breath into the belly (while relaxing and expanding the belly). Next, concentrate on a slow exhale, without strain, with a slight contraction of the belly.

Do this for a few minutes, elongating the breath as much as is comfortable, several times a day, whenever or wherever you are, in a meeting, in your car, in line at the grocery store, in a heated argument. It will ‘flip your switch’, change your life, and improve your health. It is simple, but powerful.

If you need a reminder, put up a ‘breathe’ sign at your workspace or one on your bathroom mirror.
