Well, I’m only concerned because I live in Shanghai, one of the most polluted cities in the world. In fact, I remember one week where the air quality had a measure of 160 on some index, which is approximately four times than that of Chicago, the most polluted city in the states.
I was wondering if doing cardio in such an environment be detrimental to health, and is there any specific supplementation to help cope with this environment? I regularly take a gram of vitamin c and some fish oil everyday. I would take a multivitamin, but since I’m on a prescription of accutance (very concentrated form of Vitamin A) for my skin condition, my doctor advised me to stay away from multivitamins incase I overdose on vitamin A.
