Morning Stretch Magic
Why does stretching feel so good in the morning?

You wake up. Your arms reach for the ceiling. Your back arches. Your toes point. And for a few glorious seconds, your whole body hums with a feeling that's part relief, part pleasure, part "ahhhhh." Why does that morning stretch feel so impossibly good?
While you slept, your body was basically parked. You weren't walking, reaching, or moving much at all. Your muscles stayed in the same positions for hours. Blood flow slowed down in places. Fluids pooled. Your body became a little stiff, like a door hinge that hasn't been opened in a while.
