Think of someone who takes a deep breath. What do you visualise? Eyes go wide and the lifting of the shoulders and chest? Not the way to go. Try this yourself, lift your shoulders and chest and take a deep breath in. It doesn't feel too comfortable at all does it?
Think of when you concentrate, do you hold your breath while concentrating or tackling something? I bet if you do, you might also lose your patience quite quickly.
Think of a pessimist you know, a complainer. What do they often do? They sigh in all sorts of ways, a lot.
So let's try something different. Breathe through the nose, from the abdominal area, the belly. When breathing, do it slow, relaxed, easy and tuck out the belly while doing it. You can put your hand on your belly the first times. (You can go a step further for a really deep breath and fill up the chest after the belly too).
Hold it in for a second or two as is comfortable, and while breathing out tuck the belly back in again (and chest after the belly too if you used the chest while inhaling). Pause and repeat. Deep, relaxed, easy, not audible. Do this for a while and it's easy relaxation. While you exhale and let go of the breath, you can add your worries to it and let go of them to.
You can feel how the breath intake dramatically increases, which cleanses the nervous system (who came up with that name!) bringing in fresh energy, and the exhalation gets rid of a lot of stagnant energy. So when concentrating, breathe like this, slow and easy. And you'll have a reserve of patience and composure. Instead of sighing, take a deep breath, and calming down will be much easier. Conscious breathing is being here now, and helps "avoid the droid". The automatic reactions when stressed. Dedroidify 101: conscious deep relaxed breathing from the belly as much as possible. It's also a major part of most meditation practices.
For the ladies who are (too) self-conscious, the belly coming out is barely noticeable, first of all the male eye is focused on other body parts ;p When you're standing up (or doing a presentation for instance) you are facing people so that's hardly noticeable. (They are not seeing you from the side.) Sitting down (at a table for instance) it's nearly invisible.
I tell this to everyone it may help, so about time I posted it here too.
"One conscious breath, taken many times a day, is an excellent way of bringing space into your life."
"If I had to limit my advice on healthier living to just one tip, it would be simply to learn how to breathe correctly. From my own experience and from working with patients, I have come to believe that proper breathing is the master key to good health."
