The role of breath
Our body withstands 3 weeks without food, without water for 3 days, but without breathing only 3 minutes.
Every cell of our body needs oxygen, hypoxia results in lack of concentration, general fatigue. We are getting used to this state gradually, recognizing it as the norm. Do you function normally, or do you just think so? 
Nose fulfills the basic role of filtering during inhalation of air, preventing large particles from entering the lungs. Smaller particles, which manage to penetrate further, are stopped in the mucus coating that lines the interior of the sinuses and the bronchial tree. Bronchi daily secrete about 70 grams of mucus. Cilia move the mucus up from the lungs, the epiglottis is a gate that opens, allowing the mucus to be swallowed. This process takes place without our will. If this process is slowed down or stopped, excess mucus reduces the patency in the bronchi, hindering air flow. Bronchial tree filled with mucus causes the body to mingle with just breathing.
Breathing is also work for the body. A healthy person uses 1.5% of the total volume of oxygen used by the body when resting. The condition of such low consumption is the patent respiratory system and proper posture. In conditions of bronchoconstriction, uncomfortable position or postural defects, the consumption of oxygen for respiratory work itself increases up to 20% of total oxygen consumption. Consuming so much oxygen only for breathing, we no longer have reserves to make any kind of physical effort. Forcing our body we lead to a situation in which the supply of oxygen to the muscles during exercise is not enough. This results in fainting, the formation of large amounts of lactic acid, the accumulation of which is one of the causes of fatigue. Polluted respiratory system is anoxia. When we have breathing problems, our performance is deteriorating, our brain is worse, often it comes to breathlessness and oxygen deficiency with minimal effort or even at rest.
The condition for the body’s ability to function normally is to cover the aerobic needs on an ongoing basis.
Back pain in most cases is caused by postural defects and these are associated with poor movement patterns in the Central Nervous System. The current level of knowledge with the help of modern rehabilitation is easy to deal with this problem
