How important is Pranayama (Breath of Life)?

It's our vital life force and yet most of us go about our day not paying attention to it, after all, it's something most of us can do naturally on our own with no thought about it whatsoever.  However, there are many of us who fail to realize that we are not breathing properly at all.  Shallow breathing or chest breathing is when we inhale and exhale the minimum amount of air it takes for us to stay alive, unaware that this can lead us to lung infection and even heart failure. Many of us tend to breath according to how we are feeling mentally and physically.  If we are in pain we might hold our breath to keep from feeling the pain. It's almost the same with breathing emotionally.  We might respond to stress by breathing quickly, forcing too much oxygen which can cause us to lose control of our breath. Anxiety, depression, insomnia, headaches, respiratory distress syndrome, high blood pressure and cardiac arrhythmia are only a handful of mental and physical problems that may manifest when we neglect our breath throughout the day.  It is important to adopt a time  twice a day for at least 10 minutes to sit and call to mind your breath and how vital it is to your overall mental and physical wellness.
