If you are feeling cold on dark and wintry nights, try remembering days gone by because new research reveals nostalgic thoughts would be an effective way to keep you physically warm when you are feeling cold.
The study investigated the effects of nostalgic feelings on reaction to cold and the perception of warmth. The volunteers, from universities in China and the Netherlands, took part in one of five studies.
AdvertisementThe first asked participants to keep an account of their nostalgic feelings over 30 days. Results showed they felt more nostalgic on colder days. The second study put participants in one of three rooms: cold (20 degree C), comfortable (24 degree C) and hot (28 degree C), and then measured how nostalgic they felt. Participants felt more nostalgic in the cold room than in the comfortable and hot rooms. The volunteers in the comfortable and hot rooms did not differ.
The third study, which was conducted online, used music to evoke nostalgia to see if it was linked to warmth. The participants who said the music made them feel nostalgic also tended to say that the music made them feel physically warmer.
The fourth study tested the effect of nostalgia on physical warmth by placing participants in a cold room and instructing them to recall either a nostalgic or ordinary event from their past. They were then asked to guess the temperature of the room. Those who recalled a nostalgic event perceived the room they were in to be warmer.
Study five again instructed participants to recall either a nostalgic or ordinary event from their past. They then placed their hand in ice-cold water to see how long they could stand it. Findings showed that the volunteers who indulged in nostalgia held their hand in the water for longer.
"Nostalgia is experienced frequently and virtually by everyone and we know that it can maintain psychological comfort. For example, nostalgic reverie can combat loneliness. We wanted to take that a step further and assess whether it can also maintain physiological comfort," said Dr Tim Wildschut, senior lecturer at the University of Southampton and co-author of the study.
"Our study has shown that nostalgia serves a homeostatic function, allowing the mental simulation of previously enjoyed states, including states of bodily comfort; in this case making us feel warmer or increasing our tolerance of cold. More research is now needed to see if nostalgia can combat other forms of physical discomfort, besides low temperature," he added.
The study has been published in the journal Emotion.
