3. Taoyu: I always wake up with a headache after a nap. What could be the reason?
Answer: This is likely due to autonomic nervous dysfunction. During sleep, the parasympathetic nervous system dominates, but upon waking, the sympathetic nervous system gradually becomes more active, creating a regulatory process. Your headache arises from disharmony during this adjustment phase and usually resolves after a while. It’s not a serious illness, so there’s no need to worry excessively—just try to relax more in daily life.
