WebbStage 3 is often referred to as deep sleep or slow-wave sleep because this stage is characterized by low frequency (less than 3 Hz), high amplitude delta waves (Figure 6.10). During this time, an individual’s heart rate and respiration slow dramatically. It is much more difficult to awaken someone from sleep during stage 3 than during earlier stages. Webb27 jan. 2024 · N3 sleep is characterized by delta waves, or high voltage, slow, and irregular activity.
