What is PM 2.5?
- PM 2.5 is an atmospheric particulate matter of diameter of fewer than 2.5 micrometres, which is around 3 per cent the diameter of a human hair.
- It causes respiratory problems and reduces visibility.
- PM 2.5 particles can only be detected with the help of an electron microscope because they are so small.
What are its health implications?
- As per studies, it could lead to premature death from heart and lung disease.
- Due to their smaller size, the PM 2.5 particles can easily bypass the nose and throat and can easily enter the circulatory system.
- The particles can also lead to cause chronic diseases such as asthma, heart attack, bronchitis and other respiratory problems.
How to save yourself from PM 2.5
1. Use air purifier equipped with a High-Efficiency Particulate Air filter (HEPA) filter, which can remove fine particles from the air.
2. Try to stay as much indoors, closing all windows that allow the entry of polluted air.
3. Avoid burning candles or other things which can emit smoke when you stay indoors.
4. Eat food that can increase your body’s resistance against PM 2.5.
