Why your phone is ruining your sleep (and what to do)

It's not just the blue light

You've probably heard about blue light and sleep. But the truth is, blue light is only a small part of why your phone messes with your rest. The bigger issues are psychological arousal and delayed sleep onset.

When you're scrolling through content — especially social media — your brain is constantly processing new information, making judgments, and experiencing micro-emotional responses. This keeps your nervous system activated when it should be winding down.

Realistic strategies

Nobody's going to throw their phone in a river. Here are things that actually work:

  1. Create a 30-minute "phone sunset" before bed — not an hour, just 30 minutes
  2. Switch to audio content (podcasts, music) instead of visual scrolling
  3. Keep your phone across the room while you fall asleep — close enough to hear an alarm, far enough to discourage scrolling
