Deep breathing disrupts the metabolism in cells, creates oxygen starvation, leads to the removal of useful salts (potassium, magnesium, calcium, phosphorus, etc.) from the body to compensate for the shift in the internal environment and perverts immune responses. This leads to the accumulation of under-oxidized products and substances in the body, which, in contact with external protein allergens, give allergic reactions, worsen the activity of the kidneys, liver, intestines and other organs. Therefore, a huge amount of so-called slag accumulates in the body: under-oxidized products, unnecessary salts, drugs, toxins, focal infection, excess cholesterol in the blood and its deposits with other substances in the vessels.
Now it is clear why the percentage of centenarians is higher in the mountains, an indisputable fact - there is less oxygen. If you raise the sick to the mountains, it turns out that they feel better there.
You need to try to breathe shallowly all the time (so that breathing is neither noticeable nor audible) and rarely, trying to stretch the automatic pauses as much as possible after each exhalation. Optimal implementation of this program will bring health and longevity to a person. Neglect of it, violation of the laws of nature leads to illness and premature death.
