Your iPhone has a free secret feature to help you sleep which you’ve probably never used

You iPhone has a free built-in feature that some people fork out over £100 in the shops on to help them sleep.

Making it through the night without interruptions is definitely harder for some than others. So, if you do find yourself struggling to sleep, you'll be chuffed to know your iPhone actually has a free secret feature to help you nod off which you’ve probably never used.

Many of us, believe it or not, actually find it pretty tricky to get to sleep in total silence.

And usually, to help remedy the issue a bit of background noise does the trick.

Now a lot of us will often invest anywhere between £20 to even more than £100 for a white noise machine, but did you know such device is actually built into your iPhone already?

The Apple devices running on iOS 15 or later all have a white noise feature built-in, as long as you are running with an iPhone 6s or later and your software is all up-to-date.

For those who don't know what white noise is, Dr David Neubauer, an associate professor of psychiatry and behavioural sciences at Johns Hopkins University School of Medicine, has explained all.

He said: "The key feature of the sound devices is the constant sound in contrast to changing sounds like with music, radio and television.

"Our brains pay attention to changing sound, but a comfortable constant sound can help lull us to sleep."

Obviously depending on where you live and your living conditions, sound may be at a constant anyway.

But for those who have a silent house and quiet neighbours, white noise machines provide that bit of noise that will hopefully help you drift off.

So how exactly do you enable this on your iPhone?

Well, the feature doesn't come under the label 'white noise', but is instead called 'background sounds'.

How do you enable the iPhone feature?

To enable this feature, all you need to do is simply head to settings, followed by accessibility, then audio/visual, and then you'll find the background sounds option.

Once that option has been toggled, you'll be greeted with some rather relaxing waterfall and nature sounds to help you fall asleep.

The variety of sounds you can choose from is pretty varied, including sounds of rain, stream, ocean, balanced noise, bright noise and dark noise.

These sounds can also be adjusted in volume to ensure the experience is right for you.

Happy snoozing!
