6-7.4 hours

7.4-8.4 hours

8-8.4 hours

8.4-9 hours

Correct Answer: C. In adults, sleep of 8-8.4 hours is considered fully restorative. some cultures, total sleep is often divided into an overnight sleep period of 6-7 hours and a nap of 1-2 hours. Some people may need as little as 5 hours or as much as 10 hours of sleep every day. The period of time a person sleeps depends also on the fact whether he or she has been deprived of sleep in previous days. Sleeping too little creates a "sleep debt." This debt needs to be adjusted by sleeping for longer periods over the next few days. People who sleep less have an impairment of judgment and reaction time
