We take over 25,000 breaths a day, almost all of them unconscious. When we are under stress we tend to breathe quickly, shallowly and from the upper chest. Sometimes we even gulp air. That keeps stale air circulating in the body.
Put into practice the positive habit of pausing to breathe deeply and completely. Inhale deeply and fill your belly with air and then fill your lungs. Hold the breath for a few seconds. Exhale completely letting the air in your chest out first and in your belly out last by contracting your abdominal muscles.
Do three complete deep belly breaths before you need to go into a meeting, write a report, speak to an employee or talk to your teenager. These breaths clear the head and send life giving oxygen into the bloodstream.
