Asthma is very complicated malfunction of the breathing system. It is not just swelling and/or narrowing of the respiratory passage. It,in my view,is a systemic problem. The primary and most important cause is swipe inhaling. When a person is exposed to an allergy, the system takes to swipe inhaling as a default, which until then was gentle inhaling. The harder the swipe inhaling the more the lungs resist to allow respiration into them, and the less the lungs process oxygen. If the inhaling is conscious enough, not to touch the walls of the breathing airways, the problem is reduced to a controlled level.
