According to research, sleep deprivation among teenagers can threaten mental well-being, hinder academic performance, and contribute to physical health problems. The circadian rhythms of teenagers are naturally shifted later compared to younger children and adults, which means their brains secrete melatonin later in the day. This makes it difficult for them to go to sleep at a time that will allow them to rise easily in the early morning hours when school starts. According to a study by the American Academy of Pediatrics, most teenagers require 8-10 hours of sleep per night, but the vast majority of U.S. teenagers get far less. Given the above, it is wise for high schools to adjust their start times to better align with the natural sleep patterns of teenagers. A later start time would allow teenagers to get the recommended amount of sleep and improve their overall well-being. summarize the following text
