My friend Justine is Chinese-American, and her parents are doctors who practice holistic Eastern medicine. She shared the following folk belief with me:
“Something that like, my family weirdly believes–and I’m gonna equate this to, like, Eastern medicine or like, myths in Eastern medicine–but my family hates it when I don’t wear socks because they think that if you don’t wear socks, that’s the first like, way you can get a cold. Because like, your feet–and this is true–your feet are like a good signifier of your body temperature, so like, if your feet are cold it means the rest of your body is probably gonna feel cold too. And like, if you are cold you are more susceptible to getting a cold…Also no cold drinks, because it’s like the colder your body is, the more susceptible you are to getting sick.”
Like many folk beliefs and practices in East Asian medicine, this one is not necessarily based in empirical scientific proof, but this does not mean there is no truth to it. Remedies and folk beliefs formerly dismissed as “superstitious” have often been tested and proven effective by the medical/scientific institution, and subsequently incorporated into Western medicine. This belief reflects a general practice in Eastern medicine of focusing on overall bodily wellness rather than quick cures for acute illness.
