Most teens sleep with a phone within arm’s reach. It pushes bedtime later, wakes them through the night, and cuts total sleep.
A teenager scrolling at 11pm stays awake because the content keeps pulling. Every minute there is a minute not asleep. That’s the mechanism, and it matters more than the screen’s colour temperature.
Missed sleep in teenagers looks like irritability, more anxiety, and trouble focusing. It builds too, because a tired brain has even less ability to manage impulses the next day.
⏰ One change: charge the phone outside the bedroom and buy a cheap alarm clock.
Expect pushback. Do it anyway.
