Sleepwalking pulls you out of deep sleep at the worst possible time.
Episodes occur during slow-wave (deep) sleep, typically in the first third of the night when deep sleep is most concentrated. Your brain partially wakes, enough to initiate movement, but not enough for conscious awareness or memory formation. Each episode disrupts the continuity of the deep sleep your body needs for tissue repair, immune function, and growth hormone release.
The consequences compound with frequency:
- Reduced total time in restorative deep sleep
- Morning fatigue and grogginess that don't match how long you were in bed
- Risk of physical injury from navigating the environment while unconscious
- Anxiety about sleep, particularly concern about what you might do during an episode
- Disrupted sleep for household members who are woken by or worried about the events
