Here's a useful piece of factual information.
When we start training, improving our posture, and practising Deep Diaphragmatic Breathing , a couple of physiological effects take place.
1. Our lung capacity expands and we process more oxygen to the body.
Oxygen is the number one key to survival, good health and constant energy.
2. Nature doesn't let more oxygen go to waste; she makes more red blood cells tp accommodate it.
3. Then she makes more blood vessels to carry the blood to the various parts of the body.
4. Then the blood begins to flow more freely in the system.
5. As the muscles improve in tone, they become more conditioned, more relaxed.
6. They also become more mobile, less tense and help push the blood more powerfully around the system. That takes enormous pressure off the heart and arteries.
7. Both heart and arteries can do a lot more work with a lot less effort.
And that's how getting, and keeping, ourselves fit can lower blood pressure, improve circulation, and revitalise every organ, tissue and cell in our bodies.
That's how we get too have more energy, better concentration, improved digestion, efficient elimination and greater resistance to colds, tiredness and mental fatigue.
Clinical illness or injury apart, anyone can learn and develop this vital skill. And that's what it is, a fundamental skill.
Like all skills, it has its basics, and these can be learned, developed and applied.
