Each of the four stages of NREM sleep, can last from 5 to 15 minutes.
Many people experience a feeling of falling, which can cause a sudden muscle contraction, known as hypnic myoclonia.
When the body enters stage two of NREM sleep, the heart rate slows, and body temperature drops.
Stages 3 and 4 of NREM sleep are also known as slow wave or delta sleep.
