00:00:00.607 --> 00:00:02.984
Night mode can make a phone display look

00:00:02.884 --> 00:00:06.901
warmer. Apple describes Night Shift as adjusting display

00:00:06.814 --> 00:00:10.497
colours. That feature does not establish that scrolling

00:00:10.411 --> 00:00:12.775
has become a treatment for sleep difficulty.

00:00:13.551 --> 00:00:17.274
A warmer display does not remove notifications, stop

00:00:17.188 --> 00:00:20.098
an argument or give back time spent scrolling.

00:00:20.424 --> 00:00:22.829
Ask whether the phone is keeping you mentally

00:00:22.742 --> 00:00:25.959
engaged or pushing your intended sleep time later.

00:00:26.717 --> 00:00:30.627
CDC suggests switching off electronic devices at least

00:00:30.540 --> 00:00:32.025
thirty minutes before bed.

00:00:32.352 --> 00:00:35.022
Treat that as a useful starting habit, not

00:00:34.936 --> 00:00:38.060
a precise threshold that guarantees good sleep for

00:00:38.026 --> 00:00:38.965
every person.

00:00:39.739 --> 00:00:41.996
If the phone is your alarm, set it

00:00:41.910 --> 00:00:43.262
before the quiet period.

00:00:43.575 --> 00:00:46.725
Decide which calls must get through, then put

00:00:46.625 --> 00:00:49.269
the device somewhere that makes repeated checking less

00:00:49.236 --> 00:00:50.042
automatic.

00:00:50.816 --> 00:00:53.527
Choose one boundary you can repeat, such as

00:00:53.441 --> 00:00:56.831
ending work messages or leaving social feeds earlier.

00:00:57.144 --> 00:01:00.894
Note bedtime and next-day functioning without turning every

00:01:00.794 --> 00:01:03.278
evening into a test of screen settings.

00:01:04.060 --> 00:01:07.037
The aim is enough time and a calmer

00:01:06.950 --> 00:01:08.262
transition for sleep.

00:01:08.575 --> 00:01:11.206
A display setting may be convenient, but the

00:01:11.106 --> 00:01:14.270
content, timing and length of phone use still

00:01:14.183 --> 00:01:15.482
matter to your routine.
