There are many kinds of pollution exposure that we are subjected to from October onwards – there will be gases, small particles, big particles, etc. So, anyone who has a pre-existing chest disease, is asthmatic, is a COPD patient, a patient who has other kinds of chest diseases, or the elderly will be prone to attacks of asthma, coughs, bronchitis, and even pneumonia. Children will also be affected because children and the elderly are the two susceptible age groups. The damage depends on the total dose and the duration. At the building level, even if we are exposed to it for a short period, it may impact us. On the other hand, if you are exposed to a lower level, then for a clinical impact, it requires a longer duration of exposure. It also depends on your susceptibility. So, it depends on the levels and how long you are exposed. And your body’s immunity levels or disease susceptibility levels will determine whether you have a clinically susceptible disease or not.
