Should schools teach practical habits for managing social media’s effects on identity and well-being?

Nobody taught me any of this and I paid for it at nineteen, doomscrolling through everyone else's highlight reel my first semester until my sleep and my grades both cratered. What finally helped was not a lecture, it was a psych elective where we tracked our own usage for two weeks and designed personal rules, like no phone in the bedroom. Schools already do versions of this for nutrition and driver's ed because teenagers are bad at long-term thinking; that is developmental science, not nannying. Nearly half of teens say they are online almost constantly, and we hand them the device with zero instruction. A practical habits class is the least we owe them.
