If we truly want to solve the teen sleep crisis, the data screams that the solution isn't a magic pill, but a cultural overhaul where schools start later, parents set consistent rules, and teens trade late-night scrolling for pre-bed journaling and protein snacks, all while sleeping in a cool, dark room—because frankly, our kids need a village to tuck them in, not just a melatonin gummy.
