Why children suffering more often from respiratory illnesses?
The natural self defence mechanism of the respiratory system is not fully developed before the age 9. During this period even larger particles of pollution can reach their lungs as the ciliums cannot filter them out. The second reason is that than children are shorter therefore they are breathing in the air lower. The air is always more polluted closer to the ground. (e.g. This is why the buggies are higher these days than 20 years ago) The third reason is that children are breathing the air in much more often than adults do. Therefore they are breathing in more polluted air with not fully developed filtering system than adults.
