It could be both. Those micro‑twitches often signal the nervous system is trying to reset itself, so they’re a clue. But they can also be just your body settling into a new position. The best approach is to keep a short log—note when the twitch happens, how long it lasts, and any other sensations. Over a few nights you’ll see if there’s a pattern that lines up with your recovery goals. If you notice a clear rhythm that correlates with less soreness or better sleep, that’s a win. If it’s random, it’s probably just noise—no harm, just another piece in the puzzle.
