When asked about my hobbies, I always joke that one of my favorite pastimes is sleeping. But I’m not really joking. As someone who dealt with insomnia as a teenager and often has trouble falling asleep as an adult, I’ve spent most of my life focusing on how to get better sleep. Fortunately, my personal interest in sleep perfectly aligns with my work as a wellness writer. 

While technology has made health advice easy to find, it can be hard to trust. That hurts people without access to high-quality care and unbiased information, so it’s my job to provide readers with trusted, tested and expert-backed advice for making more informed decisions about their health. I’m always on the lookout for new tips and tricks that are accessible and affordable and can make life easier for those on their wellness journey. 

When I recently considered what has made the most significant difference in my sleep quality, the first trick that came to mind was an iPhone hack I’ve been using for the past five years. I’ve reached the point where I can’t sleep without it — so I’m glad it’s built into my iPhone and not a sleep device I have to buy separately.

iPhone Background Sounds 

You can use the iPhone’s Sunete de fundal feature to play ambient soundscapes when you want to rest or focus. These include ocean (my favorite), rain, stream, night, fire, balanced noise, bright noise and dark noise. It’s basically a built-in white noise machine. 

You can enable Background Sounds to play all the time, even when other media is playing, and adjust the volume accordingly. You can also set up a feature that lets you easily turn it off by locking your iPhone. I’ve never tried this, though, as I only turn on Background Sounds at night for sleep. 

How to turn on Background Sounds

To add Background Sounds to your iPhone’s Control Center for easy access, make sure you have iOS 15 or later. You can also add it to iPadOS 15 or later. Swipe down from your screen’s top-right corner. Tap the “+” symbol at the top left and then “Add a Control” at the bottom. Scroll down to the Hearing Accessibility section and click “Background Sounds.” You can also search for it in the bar at the top. 

Once you add Background Sounds, it will be available in your Control Center. To access the sounds, simply hold down the Background Sounds icon with three music notes, select your sound and adjust the volume. The ocean sound is my longtime go-to, as I like its steady volume and repetitious waves. 

After opening Background Sounds in your Control Center, you can also click “Background Sounds Settings” at the bottom of the screen. Here, you can enable the sound to play all the time or when other media is playing on your iPhone. You can also have it so that Background Sounds turns off when your phone is locked.

Problems with Background Sounds

While I love Background Sounds and have been using it every night for the last five years, I’ve noticed one issue. I used to have it set so that when my phone was in Sleep mode, only certain people were allowed to call me in case of an emergency. However, this feature didn’t work. Even when I’d get a scam call in the middle of the night, my soundscape would stop playing and wake me up. Then, I’d have to wait for the caller to leave a voicemail or hang up before I could turn the soundscape back on, making it difficult to fall back asleep.  

I went through a stretch where scam calls disrupted my sleep almost every night. So, I set my iPhone to silence all calls during Sleep mode and told my emergency contacts to reach out to my partner instead — he’s up earlier anyway, so it works out.

When Background Sounds comes in handy

I use Background Sounds every night to drown out outside noises, but it has especially come in handy when I’m traveling and can’t control the sounds around me as much. I’ve used the feature in every single hotel and friend’s house I’ve stayed at in the past few years to drown out noisy neighbors, loud music, dogs barking, cars driving by, birds chirping and even a particularly buzzy streetlamp. I imagine it would also be great on a plane, train or boat (a full-on sensory experience for the Ocean sounds). 

The best part is that it’s all right on my phone, which means I don’t have to purchase a white noise machine or rely on a hotel or host to have one. It’s essentially like having a mini white noise machine in your pocket at all times — because who knows when or where you’ll want to transport yourself to a cozy fireside or babbling brook to catch some extra Zs?
