Having a conflict with someone? Walk it out. That's the suggestion from a social psychology paper I like by three Columbia psychology professors.* Why would this work?
First, there are the intrapersonal benefits of walking. People evolved to think on our feet, so we generate more creative ideas while moving. History is full of stories of authors, scientists, and philosophers (like Darwin, Kierkegaard, and Thoreau) who professed to formulate their best ideas while walking. Nietzsche famously said that "all truly great thoughts are conceived by walking." How many times have you been stuck on a problem and hit on the solution after getting up and moving around? The authors cite various studies finding, for example, that participants were much more likely to generate novel, high-quality analogies when walking compared to sitting. That counteracts the narrowing of vision created by conflict. In addition, other studies have found that physical activity increases positive affect and lowers stress. If you're in a better mood and less stressed out, then you're going to be more receptive to working through conflict.
