If you find it hard to get to sleep at night, this hiddeniPhonefeature might be the answer to all your problems.

Saying a phone can help you sleep is the complete opposite to what we’ve been taught aboutgood sleep hygiene. Phones and theblue lightthey emit from their screens can actually disrupt your sleep, especially if you stare at them right before going to bed. This is because our eyes can’t effectively filter blue light and when consumed before sleep, the brightness and intensity can ‘trick’ your circadian rhythm into thinking it’s time to be awake.

Having said that, one thing thebest iPhonescan do is turn into a white noise machine.What is a white noise machine?, I hear you ask. White noise combines all frequencies on the acoustic spectrum at the same intensity. With a white noise machine, they create sound that blocks out or masks other noises to avoid disrupting your sleep. An example of white noise is TV or radio static, whirring fans, steady rain or the humming of an air conditioner.

To access this feature, go to your Settings and select Accessibility. From there, click on Audio/Visual, then Background Sounds and finally, turn them on. That’s it! To customise your white noise, you can choose sounds like rain, ocean, stream, bright noise, dark noise and balanced noise. You can also choose sounds via the audio file downloads on your iPhone and adjust the volume intensity.

As this feature is designed tominimise distractions so you can focus and rest, it’ll keep playing this white noise when you lock your phone screen. But if you’d rather it stop when your phone isn’t in use, you can customise it so your background sounds pause playing when locked.

If you want to use this feature regularly, you don’t have to go through the same lengthy process each time. Instead, you can access the background noise feature through the Control Center. Simply swipe up from the bottom of your screen, and you should see a Hearing button or an icon that looks like an ear. When you tap this, you can adjust the volume and type of sound you’re playing, or you can turn it off/on.
