You don't need to buy a white noise machine if you have an Apple device.
There may be no need for people to shop online for a white noise machine that can range from $20 to more than $100. You could be holding it in your hand right now.
If the software is up to date, the white noise feature is built-in on all iPhones running the latest version of the operating system. The first iPhones with this feature were released in 2015.
What do these devices do?
David Neubauer is an associate professor of Psychiatry and Behavioral Sciences at the University School of Medicine. A constant sound can help lull us to sleep.
The constant sounds from these machines help you fall asleep and stay asleep, even though there are different sounds in your home.
The setting isn't labeled as white noise, but as "background sounds" on your phone.
You can get to this feature by going to settings.
You will be greeted with a relaxing sound when you switch on the background sounds.
Rain, stream, ocean, balanced noise, bright noise and dark noise are some of the sounds you can choose from. The sound's volume can be adjusted as well.
The only thing you have to do is choose your background sound and volume level.
When your phone is locked, you can turn on a setting that will stop the background sounds, but you won't be able to set a timer for this.
A video explaining how to turn on your phone's white noise feature is available.
If you want to use this feature frequently but don't want to follow every step, you can set up an accessibility shortcut.
If you want to turn on and off your preferred background sound, you can triple click your phone's side power button.
Go to settings > accessibility > accessibility shortcut and select background sounds The triple-tap trick can be used to turn on the white noise.
White noise sounds are a reason why many people swear by them.
There are two ways sound devices can help. Neubauer said that they can block out other noises that might awaken us.
Horns, barking dogs, and loud neighbors are some of the noises that can wake you up.
Neubauer said that the devices could provide a sense of security. It can be difficult to drift off to sleep when there is absolute silence.
If you have a sound machine that blocks noise and lulls you to sleep, you will still be able to hear important noises.
The machines emit calming sounds like rain or the buzz of a fan, which are known as brown noise or pink noise. White noise is often used as a blanket term, but true white noise can be quite harsh.
Neubauer said that a recent systematic review of sound devices did not find evidence of their benefits. Sound devices are still worth trying, he said.
It's possible to sleep with relaxing background sounds without buying a sound machine if you have a recent iPhone.
The white noise feature is only available on the iPhone 6S or later, which is incorrect. Correct information has been added to the article.
