“So other things that my parents told me about like cold being bad for you is that when I get out of the shower, I should dry my hair otherwise the cold will give me like, headaches when I grow up. And I shouldn’t work out in like a really air conditioned or cold environment, because I’m going to get sick and not like cold sick but like lifelong illness and pains. So yeah, that’s what they told me.”

The informant’s parents are Taiwanese. My parents would tell me things similar to this all the time. It seems like Taiwanese people have a lot of problems with the cold. Since air conditioning is a relatively new invention, the fear of air conditioning is reflective of the suspicious attitude towards new things that many older Taiwanese people hold. Even in the United States, many parents tell their children to dress warmly to prevent them from catching a cold. However, it has been proven beyond a shadow of a doubt that cold temperatures have little to do with illness and colds. There is no causal relationship. So how did this association between cold and illness come about?

A professor at USC studying alternative health beliefs explained to me how, based on her research, the belief came to be. Long ago, before modern medicine and the advanced understanding of disease we have today, lower class citizens often lived in squalor, had poor nutrition, and did not have the resources to keep warm. Due to compromised immune systems from malnutrition coupled with poor sanitation, diseases spread quickly through these perpetually cold populations and eventually being cold became tied to illness.
