How many hours of sleep do teens typically require each night for optimal health?

Teens typically require about 9 to 10 hours of sleep each night for optimal health due to their rapid physical and mental development. During adolescence, their bodies are undergoing significant changes, including growth spurts and cognitive development, which necessitate adequate rest. Sleep is crucial for memory consolidation, mood regulation, and overall well-being. Insufficient sleep can lead to a variety of issues, including decreased academic performance, mood swings, and increased risk of health problems.

The other options reflect lower ranges of sleep that may not adequately support the developing needs of teenagers. While some might function on 8 hours, the consensus in sleep research indicates that aiming for 9 to 10 hours is more beneficial for teens to foster their overall health and development.
