This article on chron.com published on June 28th 2012 discusses that Houston produced it's worst air quality day in 9 years on the week of the post. The intense heat coupled with the lack of air circulation led to perfect conditions for extremely dangerous smog levels. Houston has long struggled with air quality, and this day proved that much still has to change before Houston is healthy to breathe every day. The smog inflames respiratory illnesses, even to the point of some people being hospitalized. Doctors do expect to see more patients, but there needs to be bad air for consecutive days in order for it to become a very serious problem.
