Most parents know screens before bed aren't great. But understanding the why can make it a lot easier to have the conversation with your teen! Here's what's happening in your teen's brain at night:
-Blue light from screens suppresses melatonin, the hormone that signals it's time to sleep.
-Stimulating content like videos and group chats keeps the nervous system alert when it should be winding down.
-Sleep deprivation then worsens anxiety and depression symptoms, which can drive more late-night scrolling.
A few things that tend to help break it:
-A phone charger outside the bedroom removes the temptation entirely.
-A wind-down routine of even 20 to 30 minutes makes a real difference over time.
-Framing it as a sleep conversation rather than a screen time conversation tends to land better with teens.
