Explain the four stages of NREM sleep
What will be an ideal response?
Answer: Stage 1 is the lightest stage of sleep. It lasts only a few minutes. Stage 2 lasts 5-15 minutes and is deeper than stage 1. Stages 3 and 4 are delta-wave sleep. Blood pressure, heart rate, and respiration slow. These are the deepest stages. Growth hormone is released during stage 4, and sometimes people sleepwalk, cook, clean, or even drive in this stage, particularly if they are taking sleep medications.
