Awakening during slow-wave sleep causes prolonged cognitive impairment known as sleep inertia
the verdict
SUPPORTED
the evidence backs this
confidence 86/100
Awakening from slow-wave sleep frequently leads to sleep inertia, a temporary state of impaired cognitive performance, reduced alertness, and decreased psychomotor efficiency.
