Today i was gone for morning jogging..but air pollution sucks.

After 3 months... Today i gone out in cold weather for jogging and walking !
Reason behind not going for morning walk is air pollution in my area... Its air quality index is 319 which is very unhealthy considered.
I don't understand by running i will get healthy or unhealthy!

I started using pollution mask for running... But breathing is difficult in mask!
