A friend of mine is an MD who belongs to some international research organization working on the common cold. The newest research, after spending millions of dollars, says that you should drink lots of hot liquids, rest, turn up the heat, and don't eat alot. Same thing my cranky old grandmother said. He says the cold virus lives in your nose and throat and thrives in cold weather, hence the idea behind turning up the heat. Same thing my cranky old grandmother said.
I would add that after years of personal research drinking a shot of good hooch first thing in the morning when you have a cold works as well as any cold medicine. Just don't take more than one shot.
