Every year, seven million people die prematurely due to poor air quality. While it may not be obvious, the air we breathe directly impacts our health—contributing to allergies, autoimmune conditions, lung diseases, and even neurodegenerative disorders. Today’s guest joins us to explain why air quality should be a key part of the conversation on toxin exposure and how to reduce our risk of toxic air.


Today on The Dhru Purohit Show, Dhru sits down with Dr. Elroy Vojdani to discuss the critical link between air quality and the rise in severe health conditions. Dr. Vojdani explains why air quality isn’t discussed enough, how to monitor it, and how to adjust your daily activities accordingly. He also breaks down the best ways to support detoxification, the top supplements for recovering from toxin exposure, and practical tips for improving indoor air quality at home and in the office.
