Context:

Madeleine Hall is Junior at USC, studying Communications. When I set out to explain folklore to her, for some reason my mind went straight to folk remedies and I gave her several examples of these, and then got into general folk beliefs around sickness. Obviously, my niche explanation led to this piece of folklore she then provided.

Transcript:

Madeleine: There are two parts of it, though. The first part is my Mom used to say that you can’t go outside with your hair wet because you’ll get a cold when it was cold out, or really hot out, doesn’t really matter, you’ll just get a cold. Uhhm, annndd, the other one is that you can’t go to bed with your hair wet, which really makes no sense, uhm, but now I dry my hair before bed every night, because I’m not gonna go to bed with my hair wet.

Interpretation:

This is something I investigated to see if there is any scientific truth to it. It seems that there is no science behind this claim, but I had also heard it before. Many people had, it seems, because after typing only a few words into Google, Google auto filled the rest of my search. Like drinking eight glasses of water a day, or the above wet hair folk belief, many people often hear these things over and over. With the Internet, people can finally seek out their validity.
