About 200 Soviet and Russian medical doctors applied this simple breathing exercise on thousands of patients with asthma, heart disease, COPD, and many other conditions. This breathing exercise is indeed very simple, and it is the most natural and the most simple solution so called home remedy, because it does not require anything. Furthermore, this exercise provides the human body with more oxygen in the brain, heart and other body cells because people with all these conditions hyperventilate. They breathe much more than the medical norm: And that causes constriction of blood vessels, a loss of CO2, and reduced oxygenation of all vital organs: Therefore, the exercise, when it is done, is performed in the following way. You pinch your nose and start walking. Usually people with a stuffy nose can walk somewhere about 15, 20, 25 steps. After this period of walking, with your mouth closed and nose pinched, you are going to get air hunger, a desire to breathe more, because you did not breathe during these steps. What you do next, you sit down, release your nose, and start breathing, but only from the nose. Remember when you finished walking with your nose pinched, you need to inhale only from your nose because, in the nose, we accumulate nitric oxide, a powerful vasodilator. In addition, we get more CO2 (carbon dioxide), which is the most potent known dilator of blood vessels. It provides more oxygen for the brain, heart, all organs in the human body. Now what is done next, instead of your heavy breathing, because, if you have a stuffy nose, that means you suffer from hyperventilation, you need to reduce or slow down your breathing pattern. That means, instead of taking your big inhalation, you are going to take an inhalation which is little bit less, maybe about 10-20% less than you have right now. What you do next then, you slowly exhale that means you need to exhale just by relaxing your breathing muscles. So you take an inhalation using your diaphragmatic muscles, inhalation again should be small, about 10-20% less, then you immediately relax to exhale. Then you take a next inhalation, virtually immediately, again about 10-20% less, in comparison with what you have right now, and then you relax your diaphragmatic muscles. So you continue to breathe in this shallow or reduced manner for about 1 minute. And, up to 90% of people or even more found that they can easily unblock their nose, and sometimes people suffer from this problem for many, many months. So this exercise has a very high success rate.
