At the beginning of zero had an interesting idea about hypertension. About the fact that it is our payback for walking upright.
We spend a lot of time still upright. And even when we sit, then sit on high chairs. They say: "He fell off the chair."
In this case, the blood stagnates somewhere below. Heart heavy to lift it up. The sympathetic nervous system begins to help and stimulates the heart. Such stimulation increases the blood pressure. And every time we sit, stand or loiter slowly, she encourages and stimulates. Pressure is consistently higher than it could be. And then it unharness pressure and begins to live his own life.
Remember the movie about the Amazon Indians? Those or squat, or slow something somewhere dragged. This is the natural state of man.
Every once in a squatting position blood is squeezed out of the vessels of the legs to the heart.
And during the slow carry small loads going on about the same thing - the muscles squeeze the blood.
The heart can easily handle such a preload. There is nothing to encourage. Help the heart muscle.
It's not even inactivity, and body position and gravity. It seems that the lazy, lying on his left side, is more useful than just a stand, propping up the wall.
It turns out that the pressure may rise because of the constant struggle of the heart against gravity.
Have you ever wanted to get into the chair with your feet?
