๐ Understanding Teen Sleep Patterns
This paragraph explains the natural sleep tendencies of teenagers, which are influenced by their circadian rhythm. Unlike children, teens experience a delay in sleepiness signals, making them 'night owls'. Their body also delays the alerting signals needed to wake up, leading to a preference for sleeping in. This biological rhythm often clashes with early school schedules, causing sleep deprivation. The American Academy of Sleep Medicine suggests that teens need 8 to 10 hours of sleep per night for optimal health, but CDC data reveals that less than a quarter of high school students achieve this. A movement to start schools later in the morning is growing to help teens get more sleep, which is crucial for their health, mood, academic performance, and safety.
