Chest Infection: Reasons and Remedial Measures


A chest infection is an infection of the lungs and respiratory tract. It causes inflammation in airways and pus formation in alveoli. Chest infection is very common these days. We see every other person coughing, sneezing, or, showing other symptoms of chest infection. 

What is the reason behind it?

 The enormous progress in science has made our lives easier and more luxurious. But if, on one hand, these stupendous inventions have brought us many advantages, on the other hand, the same inventions have some bleak outcomes on our health and environment. Chest and Sinus infections are also one of those side effects.

Toxic smoke from vehicles and factories pollute our environment to such a great extent that our respiratory tracts fail to filter that pollution. Deforestation all around the world is also adding up to this poison. Green plants and trees are the lifesavers for us and our environment. But we are killing them for decades. Plants can reduce the amount of carbon dioxide in the air. They regulate oxygen supply in the atmosphere. But no thanks to the insatiable desire of implanting new factories and industrial units everywhere, we are losing these benefits.
