The Science of Resistance
As I lay there on the second night, comfortably propped up by the folded comforter, I started to understand the mechanism. When you sleep on a soft mattress, your muscles are constantly micro-adjusting to find stability in the “soup” of the foam. They never truly relax. On the floor, however, the surface is stable. Once your body realizes the ground isn’t going to move, the muscles can fully let go. It’s a concept called “grounding” or “earthing” in some circles, though I was just focused on the mechanics.
I could feel my back muscles twitching—a phenomenon called fasciculation. It was as if they were finally off-duty after years of overtime. The floor forced my shoulders to roll back and my chest to open up. On a soft mattress, the heavy shoulders sink in, hunching you forward even while you sleep. On the floor, gravity pulls the shoulders back, correcting the “computer hunch” posture I had developed over 15 years of office work. It was uncomfortable, yes, but it felt like “good” pain. Like stretching a tight hamstring.
