Smog! I first heard this word when I was in my third or fourth grade…way, way back. My teacher told me that during winters you get a thick blanket of fog that combines with smoke and becomes something that is so polluted that you can’t see your way around and it is bad for you. Well, I didn’t understand much then. Back then too much smog was actually a good thing to me! I got to skip school, my mom and dad took a day off,and we used to spend all day together. Having two working parents, this was a welcome thing for me. The heavier the smog, the happier it made me. But then I grew up. I started understanding what it is in reality, how it affects our health and why it made my parents overly anxious. I understood that is why we moved from Delhi. My parents, like many others in Delhi, were striving hard for ourgood health and smog wasn’t helping. While this word was initially used to refer to a mixture of smoke, pollutants,and fog, the one we know now is more complex than that.This is because the former was just part of winters and used to subside once the fog days get over, but the newer one can happen even during summers. I understood that this smog was basically a mixture of nitrogen oxides and various other pollutants that react with sunlight to form ground-level ozone. This photochemical smog forms a heavy haze over the city and makes it incredibly hard to breathe.         

How does it impact us?

While ozone in the upper layer of our atmosphere is a good thing which prevents UV rays from entering our atmosphere, the same can’t be said about ground-level ozone. Here are some ways they impact our health with prolonged exposure.

Persistent Cough and Irritation in the Throat and Chest

Exposure to ground-level ozone can irritate your respiratory tract and lead to a heartburn kind of sensation. You may even have a bout of persistent cough and heartburn for many hours post exposure. Ground-level ozone continues to affect your lungs days after the initial symptoms fade away.

Triggers Various Diseases and Ailments

If you have a preexisting respiratory condition, this smog is sure to trigger it more. People suffering from asthma and wheezing have experienced severe episodes of it within minutes of exposure. Extreme smog lowers the production of Vitamin D and leads to deficiency disease like rickets. It can also trigger cardiovascular and bronchial disease among people.

Respiratory Distress and Lung Damage

Smog can also cause heaviness and breathing distress. You will feel suffocated and gasping for breath on prolonged exposure. Young children, infants, people with respiratory ailments and senior citizens would be the most susceptible to this as they have a weak immune system and lungs.

An Afterthought

I was pretty young when I thought smog was good, but even now when I hear people debate about air pollution, there is minimal mention of smog,or at least few realize it is an all-year thing. Smog is air pollution in disguise,and it is increasing everyday creeping on us slowly and making us sick. It is time we stepped ahead and did something about it. But what can we do?
