Asthma with Tim&Moby


Asthma is a common condition of the lungs. People who has asthma can experience coughing, shortness of breath, tightness in the chest. But having a cough does not mean you have asthma. When we breath, air is sucked into narrower and narrower into hundreds of little sacs called alveoli. In here, blood if refreshed with oxygen and carbon dioxide is expelled.
But the air that we breath is not always as fresh as it could be. There is bunches of gunk in it like smoke, pollution, mold, pollen, pet dandruff, dust particles, the list goes on for ever with the mutating viruses!(See the swine flu entry for more info)To people with asthma, these gunk trigger an asthma attack. Attacks like this can also be triggered through exercise, food allergies, weather conditions, and even strong emotions. It just depend on the people.
During an asthma attack, the lung air ways gets irritated. When the cells in the air ways detects a trigger, it overreacts and spits out chemicals to make the mucus production increase, causing the airways to swell. The swelling and mucus makes the airways narrower and narrower that is hard to breath. That is why people with asthma keep their inhalers handy at all times. When an asthma attack happens, the medicine in the inhalers go inside the airways and reduce the airway swelling to make breathing easier. Checking your peek flow meter daily is good, too. Doctors are really good at diagnosing, and treating asthma. That is good because then people with asthma can now run around and do all sorts of stuff. There is even Olympic sports champions with asthma too to show you how treatable it is.
Even because the asthma is a common conditions to the lungs, it is still easily treatable. Have a nice day!
