Is Air Conditioning Bad for You?

The cooling industry worked hard to promote the idea that A/C makes us more healthy and productive, and in the years after World War II it gained acceptance as a standard home appliance. Still, marketers worried about a lingering belief in the importance of fresh air, and especially the notion that the "shock effect" of moving too quickly from warm to cold would make you sick. Some of these fears would be realized in a new and deadly form of pneumonia known as Legionnaires' disease. In the summer of 1976, around 4,000 members of the Pennsylvania State American Legion met for a conference at the fancy, air-conditioned Bellevue Stratford Hotel in Philadelphia, and over the next month, more than 180 Legionnaires took ill. The bacteria responsible for their condition were found to be propagating in the hotel's cooling tower. Twenty-nine people died from the disease, and we finally had proof that air conditioning posed a mortal danger to America.
