Teenagers need 8-10 hours, not 7-9, but it's not just about the total time spent asleep (although this is super critical for teenagers as they need much more) it's about the quality of sleep. Devices close to bed time stimulate the mind with a range of hormones and thought patterns. while teenagers might be able to fall asleep in the same way, they don't sleep as well. This being defined and less regular cycles and fewer and shorter phases of deep sleep, especially in the last phase of deep sleep (the most critical). Without doubt making teenagers get up early to study has a detrimental affect of their learning and it's only our arcane societal norms around sleep that continue to compound this problem.
