Sleep duration recommended for ages 12 to 18 is between how many hours per day?

• A. 7 to 8 hours
• B. 8 to 9 hours
• C. 10 to 11 hours
• D. 9 and 9 1/2 hours

Answer: (D)

Adolescents need enough sleep to support growth, mood, memory, and daytime functioning, and their bodies naturally require more rest during these years. For ages 12 to 18, the typical guidance points to about 9 hours of sleep per night, with many health sources placing a practical range around 8 to 10 hours. The option that centers on roughly 9 to 9.5 hours aligns well with this guidance, providing a solid target that fits the average teen while allowing for individual variation in sleep needs and daily schedules. Getting about 9 hours helps maintain alertness and mood and supports learning, whereas consistently getting far less can lead to daytime sleepiness and impaired performance, and sleeping much more than 10 hours is usually more than most teens require. So aiming near 9 hours a night is a sensible, well-supported target for teens.
