How long before bed should phone use stop?
A good rule of thumb is to stop using your phone 30 to 60 minutes before bed. This gives your brain time to shift out of “alert” mode and into sleep mode.
If you use your phone right up to lights out, it can make it harder to fall asleep. The combination of bright light, notifications, and scrolling can keep your mind switched on.
Why phone use can affect sleep
Phones can interfere with sleep in a few ways. The screen light may suppress melatonin, the hormone that helps your body feel sleepy.
Even more important, the content on your phone can be stimulating. Social media, messages, and videos can keep your attention going when you should be winding down.
A practical bedtime routine
Try setting a cut-off time for phone use and replacing it with a calmer activity. Reading a paper book, listening to gentle music, or doing a short relaxation exercise can work well.
It also helps to charge your phone outside the bedroom if you can. That reduces the temptation to check it after you’ve gone to bed.
If you need your phone at night
Some people rely on their phone for alarms, sleep apps, or family contact. In that case, switch on Do Not Disturb and lower the brightness well before bed.
You can also use Night Shift or a blue light filter, but these are not a full fix. Reducing use before bed is usually more effective than relying on screen settings alone.
What works best in real life
The best cut-off time is the one you can stick to consistently. For many people, 30 minutes is realistic, while 60 minutes gives a stronger buffer.
If sleep is a regular problem, keep the routine simple and repeatable. A steady wind-down habit matters more than getting it perfect every night.
