Feeling cold is contagious
If you've always thought that feeling cold is contagious, a team of researchers at the University of Sussex says you just may be right. They've published a study saying that even watching videos of people who seem to be exposed to cold may actually lower your body temperature. They referred to this as "temperature contagion."
The scientists asked 36 volunteers to watch videos of actors putting their hands in either visibly warm or cold water. At the same time, the voluteers' body temperatures were taken. The researchers found that the volunteers’ hands became significantly colder when watching the cold videos, while the warm videos produced no significant change.
Lead researcher, Dr. Neil Harrison suggested that the reason for this was because humans are social creatures. He said: “Mimicking another person is believed to help us create an internal model of their physiological state which we can use to better understand their motivations and how they are feeling.”
The study was published in PLOS ONE.
