Whether a ten-minute nap can feel worse than no nap at all

I took a ten-minute nap after lunch and woke up feeling more disoriented than before. Other days a similarly short rest is wonderful. Is it mainly about accidentally entering a deeper sleep stage, how tired I was beforehand, or the time of day? I know longer naps can create sleep inertia, but I'd love a straightforward explanation for why a tiny nap sometimes backfires too.

      The weird part is that “short” doesn’t always mean “light.” If you were already exhausted, the nap can be tiny and still land you in mush-brain territory.

      I get this after lunch if I nap on the couch instead of at my desk. It’s not the length so much as the terrible place and the worse timing.

        That fits my experience, honestly. The same ten minutes can feel like a reset or like I got hit by a small truck.
