We know, in short, that cold weather affects our mood in the short term, but does exposure to icy conditions have more lasting effects on your personality as well. Actually yes, a new study published in Nature this week finds. All other things being equal, a child growing up in sunny California, for instance, will be more open, agreeable, and even keeled than one growing up in snowy Buffalo, the researchers demonstrated. Less warm thermometers, less warm people. People who grew up in places where the average temperature was closer to a comfortable 74 degrees were, on average, more agreeable, more open, and less neurotic, they found. Growing up in temperatures that are close to the psychophysiological comfort optimum encourages individuals to explore the outside environment, thereby influencing their personalities.
So don’t let your stereotypes run wild, but on a broader level, it’s fun to know that whether you grew up among palm trees or blizzards probably left it’s mark on your personality. The essential point here is that these results deal in averages across populations and shouldn’t be seen to reflect any one particular individual or subset of people. Plus, in an additional complicating factor, other research has shown that our attitude towards the weather also affects how it impacts us.
