When John started his first class in college, the first comments from the college professor was for all the students to get at least 5 to 6 cycles of sleep every night. The professor told the students they would be more successful in college and also be much more healthier if they got the 5 to 6 cycles of sleep. John did not know what a cycle of sleep was and he did not know that sleep occurs in a cyclical pattern. In your FRQ, please explain to John the 5 stages of sleep and how the cyclical pattern occurs. You must include the following concepts. Please define them, include them in the correct stage and give an example why they are important. Length of each stage and length of one cycle Alpha waves Theta waves with sleep spindles Delta waves & deep sleep chemical replenishments night terrors REM sleep Paradoxical sleep
