You raise your collarbones and/or raise your shoulders? Observe your neck muscles, do they bulge out? Does your ribs flair outward during inhalation?And if you place your left hand on your chest and your right hand on your belly. Now breathe in. Does your left hand rise first? If so your breathing is shallow.
You can either stand, sit, or lay down. Observe your breathing pattern at its natural form. Using a watch, count your complete breaths in one minute. A complete breath is one inhale and one exhale and possibly a pause at the end of the exhalation. Try not to skip any numbers or hold your breath during this process. Then see how many complete breaths you had in one minute.
Now begin to breath deeper and calmer and try to reduce your counting from two to one. For example if you counted two natural breaths, now count one deep breath. In another word see if you can cut the counting to half in one minute. Repeat this process until you can master a minute. Then increase the time till you feel comfortable without strain on your body.
By practicing daily for a period of 10 to 15 minutes, you will experience changes in the followings: Improved sleep pattern, better diet, positive emotional and mental signals, better sitting and standing posture, more vital energy and better general health.
