The physiological nature of slow-wave sleep raises the threshold for awakening from external stimuli

the evidence backs this
confidence 79/100
The physiological characteristics of slow-wave sleep, including neuronal silence and EEG slow-wave activity, contribute to sensory decoupling and elevate the threshold required for external stimuli to trigger awakenings.
