What is asthma?
When you’re breathing healthy you will not notice the process as it isn’t a struggle. Asthma is a common long term inflammatory disease of the airways. From my reading of what asthma is on the Society of Asthma website I have discovered that it affects the airways in your lungs. The airways (alveoli) in your lungs have small tubes that carry air in and out of the lungs. The Asthma Society of Ireland says that when the airways become sensitive to the cold or dust, this irritant then causes the muscles around the wall of the airway to tighten up making it difficult for the air to flow in and out.

Every individual will have got asthma because of several possible reasons.McKeown 2003 pg8 tells us that over breathing also causes asthma the part of the brain that regulates the amount of air you breathe becomes accustomed to breathing too much. McKeown 2003 then gives references to a paper entitled Hyperventilation Syndrome and Asthma, by Dr Stephen Demeter and he states that: ‘prolonged hyperventilation (24+ hours) seems to sensitize the brain, leading to more prolonged hyperventilation’. McKeown is telling us that once this is habitual or long term, even if the cause is removed the behaviour is maintained. A few obvious reasons would be like smoking during pregnancy, being overweight and the levels of air pollution in your area (The Asthma Society of Ireland). An interesting fact I learned from Asthma and Allergies: The Science Inside is that if you weren’t exposed to enough bacteria and viruses as a child your immune system is further weakened and that could be why someone has developed asthma. 80% of people in Ireland who has asthma also have hay fever (The Asthma Society of Ireland). Having allergies means that your immune system overreacts to allergens that wouldn’t cause symptoms in most people. Asthma and Allergens are caused by an allergic reaction and are related conditions linked by an airway. Asthma does tend to run through families so your chances are heightened if a parent has the
