The air quality index of between 0 and 50 is considered good and if you are living at a place where AQI is good then you will live longer and avoid many diseases.
Unfortunately in today's world we hardly see any good AQI near our location. If i talk about my location the AQI is poor i e more than 200.
In today's news there was a guideline forward to the people of my state that people should avoid moving out of their house because of poor AQI and continuous rise in temperature.
The highest temperature recorded here was approx 50°C and currently it is 45°C and heat waves have made it difficult for us to move out.
Clean air is very necessary for a healthy lifestyle but we no one of us have that in our life.
Maybe few people here might be living at a place with very good natural conditions but majority are away from it because of rapid industrialization.
Anyways do what you can , if there is a park near your house then atleast go there to take in fresh air for sometime. That's all i can say , thank you.
