A number of studies show that feeling generally cold outside or indoors will not cause a cold. Having cold feet, however, can make you more likely to get one.
Researchers at Cardiff University's Common Cold Center (Wales, U.K.) say that having very cold feet could jump-start a cold. Cold feet, the doctors explain, cause constriction of the blood vessels in the upper airways, which may reduce your body's defenses against viruses.
It wouldn't hurt to make yourself comfortable and reduce your chance of a cold at the same time.
Put on some thick socks if the floor gets drafty when you watch television, and wear them outside when the weather is frigid.
