Scrolling through Reels, checking messages or watching videos before going to sleep has become a routine for many people. But this seemingly harmless habit can affect both the mind and sleep. Spending long hours looking at a phone, especially late at night, may make it harder to wind down and can push bedtime later than planned.

This is why experts often recommend keeping your phone away for at least an hour before going to bed. But what actually happens when you make this small change to your nightly routine?

Your Body Gets Time to Prepare for Sleep

According to Dr. Amit Kumar Mandal, Senior Director of Pulmonology at Paras Health Hospital, putting your phone away at least an hour before bedtime gives your body and mind time to gradually prepare for sleep.

Sleep is closely linked to the body's circadian rhythm, the internal cycle that helps regulate when we feel awake and when we feel sleepy.

Light exposure at night, particularly from screens, can interfere with the body's natural production of melatonin, a hormone that helps signal that it is time to sleep. Reducing screen exposure before bedtime can therefore make it easier for some people to fall asleep.

You May Fall Asleep More Easily

One of the biggest advantages of avoiding your phone before bed is that your mind gets a chance to slow down.

When you're constantly scrolling through social media, watching videos or responding to messages, your brain remains engaged instead of transitioning into a relaxed state. Once the phone is put away, there are fewer digital distractions competing for your attention.

This can make it easier to settle down and prepare for sleep.

Your Bedtime May Become More Consistent

Have you ever picked up your phone intending to scroll for five minutes, only to realise that half an hour has passed?

Social media, videos, news and notifications can easily extend screen time late into the night. As a result, you may end up going to bed much later than planned.

Keeping your phone away an hour before bedtime creates a clear boundary between screen time and sleep time. This can help you maintain a more consistent bedtime and prevent unnecessary delays.

Your Mind Can Feel More Relaxed

Phones don't just expose you to light—they also provide a constant stream of information.

Messages, social media updates, work notifications and news can keep your mind occupied even when you're physically tired. Taking a break from these digital stimuli can give your brain some quiet time before sleep.

Instead of reaching for your phone, you can try reading a physical book, doing some gentle stretching, practising meditation or simply having a quiet conversation with family members.

You May Feel Better the Next Day

A better bedtime routine can contribute to getting adequate and more consistent sleep. Quality sleep is important for feeling refreshed, focused and energetic during the day.

However, simply switching off your phone doesn't automatically solve every sleep problem. Your overall routine also matters. Getting enough sleep, maintaining regular sleeping and waking times, and following healthy habits are all important.

Make the One-Hour Rule a Habit

You don't necessarily have to make a dramatic change overnight. Start by setting aside the final hour before bed as phone-free time.

Keep your phone away from the bed, turn off unnecessary notifications and replace scrolling with a relaxing activity. When practised consistently, this simple habit can help create a calmer transition from your busy day to bedtime.
