Somebody tells you to “just go for a walk” when you’re stressed, and it can feel almost insulting, like the suggestion doesn’t match the size of what you’re carrying. It’s such a small, ordinary piece of advice. It also happens to be backed by a surprising amount of research, more than most casual advice ever gets. That doesn’t mean a walk fixes everything. It means something measurable is actually happening when people spend time outside, and it’s worth understanding what that something is.
