Very few people spend much time in consciously controlling their breathingIn fact for the majority of people, breathing is simply an automatic process that happens unconsciously. Unfortunately, this includes breathing in an unhealthy way.Most of us are well aware of our body's need for oxygen. Without it we would very quickly become unconscious and die.But contrary to popular belief, carbon dioxide is just as essential to life as oxygen.When we breathe incorrectly, we reduce the amount of carbon dioxide available to us and this can have a profound and harmful effect on our body - and our mind.You see, if there is insufficient carbon dioxide in the blood, it creates 'alkaline blood', which causes a constriction of the blood vessels.And this in turn allows less oxygen to reach the vital organs.Incorrect breathing that decreases the carbon dioxide available to our bodies can cause a whole range of health problems.Included in these are cardiac problems, including 'angina' and palpitations.The respitory functions may also be affected producing chest pain, shortness of breath and asthma. Also, muscular cramps, tremors and fibrositis may be experiencedAs if this weren't enough, psychologically speaking, incorrect breathing that limits the amount of carbon dioxide available can create real tension, anxiety, sleep disturbances and a lack of concentration.All of these things are good reasons for you to learn how to breathe in a proper and healthy way.Here's a simple 5 step approach to healthy breathing.1. Inhale and exhale through the nose whenever possible, even during physical exercise. Simply because the nostrils are smaller than the mouth, the volume of air is greatly reduced.2. Change from breathing with the chest to breathing with the abdomen or belly. An easy way to do this is to relax in a chair, put one hand on your tummy and the other on your chest and then breathe so that the hand on your chest hardly moves while the hand on your stomach rises and falls gently.Once you have mastered this way of breathing, work on doing it while standing and then move on to learning how to use it when walking and moving around.3. Focus on making your breathing shallow. Try to minimise the movement of the hand resting on your tummy.4. Make your breathing slow in order to minimise your breathing. The aim is to breathe around 6 to 8 breaths per minute - or about 1 every 10 seconds.5. Focus on developing a regular and steady rhythm. This will cause you to stop holding your breath for irregular periods and then 'sighing'.Practice breathing like this for a minimum of 3 times a day for at least 10 minutes.Be patient!It takes time to change anything as entrenched as our breathing habits, but with persistence you can certainly do it.The effort really is worthwhile and, as the supply of oxygen to your body's vital organs improves so will your physical - and psychological health.
