Why Walking Is Good for You

Made for you, by AI, from the sources below.
Why walking is one of the best-supported things you can do for your body and your mind: what daily steps do to your risk of dying early and where the curve flattens, what a walk does for blood pressure and blood sugar, why pace can stand in for volume, the trial evidence for mood, sleep and memory, and why pairing a walk with something you want to hear is what makes the habit last.
