151). A person’s body temperature will begin to lower, muscles will become more relaxed and they may experience hallucinations. An EEG would show theta waves during this stage. During the 2nd stage of sleep theta waves continue but the EEG shows additional “bursts of electrical activity called sleep spindles and large waves call K-complexes appearing every 2 minutes or so” (Licht, Hull, Ballantyne, 2014, p. 152). Stage 2 is a deeper sleep than stage 1 and a person spends more time in this stage than any other during the night. Stages 3 and 4 are very similar. They are both considered deep stages of sleep but stage 4 is a deeper sleep and it is difficult to wake someone up during this stage and if you do, the person may appear irritated and confused. Stage 4 lasts for approximately 40 minutes. Brain waves for these two cycles are known as delta waves. In a study conducted at The University of Florida research showed that people who showed signs
