Dear readers,

It is a shame that even in this era in which the issue of environment and pollution is taken up with so much seriousness around the world, our city is still suffering from issues such as pollution from stubble burning.

While I do hope that the government finds a solution to this problem with utmost urgency, in the mean time we spoke to Dr Kamal Arora (Associate Professor, DMC, Ludhiana) to guide us as to how to protect ourselves from the effects of SMOG till it agrees to subside.

Simply put, Smog is derived by merging the two words; smoke and fog that makes the air hazy making it difficult to breathe.

During the winter months when the wind speeds are low, it helps the smoke and fog to become stagnate at a place, forming smog, and increasing pollution levels near the ground closer to where people are respiring. It hampers visibility, disturbs the environment and is harmful to humans, animals, plants and the nature as a whole.


Smog is known to cause,

  • Many types of ailments from minor pains to deadly pulmonary diseases such as lung cancer
  • Irritation in the eye
  • Inflammation in the tissues of lungs; giving rise to pain in the chest
  • Other issues or illnesses such as cold and pneumonia
  • Minor exposure to smog can lead to greater threats of asthma attack in people suffering from asthma problems

  • Limit your outdoor activities if ozone levels are unhealthy, as elevated ozone levels increase your chances of being affected by smog the longer you stay outside.
  • Keep your activities gentler on smoggy days, as the more vigorous your activity level, the greater your chances of experiencing respiratory problems.
  • Wear any mask that covers the nose and the mouth; N-95 is advisable.
  • Drink plenty of fluids such as fresh juices high in Vitamin C, coconut water etc.


  • Air Purifier is one of the technological innovations which acts as a saviour in times like these. There are several companies, from big brands to new ones, which have their air purifiers in the market. However, there are a few things which need to be kept in mind before you buy the device.


  • Firstly, you will have to determine the size of your room, noise levels, electricity consumption, filter replacement price, and certifications.
  • Buyers need to check if their Air Purifier is HEPA labelled. HEPA means high-efficiency particulate air. It is a technology that absorbs particulate matter present in the air of your room. You will have to replace it regularly.
  • You will then have to check the range of the device. The air delivery rate should be over 300 cubic meters so that it covers your room. Preferably do not buy an air purifier with over 100-watt power.

Our sincere thanks to Dr Kamal Arora for sharing this valuable information with our readers. Wishing all of you good health and well being.
