Stage II: People drift further into sleep and breathing becomes more shallow and irregular. K-complexes occur during this stage. Less than 50% of sleep time is spent in this stage.

Stage III: In this stage there is a transition towards the next stage before. There is slow wave sleep made up of 20-50% delta waves.

Stage IV: I It occurs around midnight. People spend about 30-minute in this stage the first time
