Lower blood pressure

The high pressure  is caused by a lack of oxygen in the blood, can try this taking our pressure blood before and after practice exercises of breathing deep, will see that the pressure low of way significant after exercises of breathing deep.  I suffer of the pressure high and know that this disease can lead to other diseases, as diseases heart, affects our health mental, our health kidney etc. I look for a means of lowering the pressure and from a logical reasoning I thought that the oxygen being a gas once in the blood can absorb some of the pressure by varying its volume, I started to test this reasoning and the result was positive, it is possible that my first reasoning is wrong, but what is certain is that the pressure can be lowered with a good oxygenation.  I do not recommend anyone to stop taking the tablets to lower pressure but they must understand that they have a lack of oxygen in the blood..To have a good oxygenation of our organism is necessary strengthen the system cardiovascular and them lungs, thinking that more blood pumped the heart, greater will be the amount of oxygen that circulates by our body.
