How many hours of sleep are recommended for college students?

• A. 6–8 hours per night
• B. 7–9 hours per night
• C. 9–11 hours per night
• D. 5–6 hours per night

Answer: (B)

The main idea here is that enough sleep supports learning and daily functioning. For adults, including college students, seven to nine hours of sleep per night is the recommended range. This amount helps with memory consolidation, attention, problem-solving, mood, and overall health—all things that strongly influence academic performance. College life can mean irregular schedules, so aiming for seven to nine hours most nights creates a solid foundation for focus during classes and exams, plus better energy for studying and activities.

If you regularly sleep less, like five to six hours, daytime fatigue, poorer attention, and weaker memory can follow. Sleeping nine to eleven hours is usually more than most people need and can reflect unnecessary oversleeping or other factors. Six to eight hours is close but may still fall short for some students who need a bit more for optimal functioning. So, seven to nine hours per night is the best, universally recommended range.
