Slow-wave sleep, also known as deep sleep, begins during NREM stage 3. This stage is characterized by delta waves in the brain, which are slower and have higher amplitude than the waves in earlier stages (NREM stage 1 and 2). During slow-wave sleep, the body is in a state of deep relaxation and restoration, with reduced heart rate, blood pressure, and breathing.
