Is my phone actually why I can't sleep?

What the screen really does

1. It skips your sleepy window. Sleepiness comes in waves. Scroll through one and the next may be an hour away.
2. It keeps the engine running. News, DMs, a video that makes you feel something: your nervous system does not know it is 11pm.
3. It breaks the bed rule. If the bed is where you watch and scroll, lying down stops meaning sleep.

Why you stay up late even when you are exhausted

There is a name for it: revenge bedtime procrastination. The day belonged to everyone else, so the night is the only time that feels like yours, and you spend it awake to prove it. It is a control problem, not a sleep problem. The fix is to give yourself real personal time earlier in the evening, on purpose, so the night does not have to carry it.

The rule that made mine stick

Willpower at 11:30pm is a terrible plan. Mine lost every night for years. So I stopped relying on it. My phone's social apps are locked on a schedule every night from 11pm to 8am. It still works as a phone: alarm, calls, my ocean sounds. Nothing to fight, so the bed rule finally held. You can use your phone's built-in limits if you will respect them (most people override them in two taps). What matters is the rule: social media is off from bedtime until you are up, and something other than you enforces it.

TV in the bedroom

Same story with a bigger screen. Light and sound fragment sleep even when you drift off. If you must, a sleep timer, dim, and something boring. Better: the TV lives in another room and the bedroom is a cave. Cold, dark, quiet, sleep only.
