If you’re feeling hot and want to cool off...
...search for hashtags on Instagram like “Polar Plunge,” “Snow,” and “Ice”. Or watch a movie like “Fargo,” “Mystery Alaska,” or “March of the Penguins.” Because just seeing other people who are cold makes us cold too. In a study, people who watched others plunge their hands into ice water saw their own body temperature drop. That’s because we’re naturally empathetic – and seeing something happen to others, like shivering in the cold, triggers our neurons to mirror whatever that person is feeling.
