I'm somewhat of a fanatic when it comes to optimizing sleep. While I have not convinced myself yet to try and reduce it drastically, I have tried different things to make it better and improve my overall health in the process.
I don't sleep well most of the time which I attribute to a couple of things including working long-hours in front of a computer monitor and being rather noise sensitive.
I hear things that others don't hear or don't mind hearing which is one of the things that is keeping me awake at night.
One of the solutions to that issue is to play relaxing sounds or music instead. I have tried many applications and sounds in the past, from all kinds of colored noises -- white noise sounds for example -- to the relaxing sound of waves or water flowing down a creek.
MUJI to Sleep is a free application for Android that has been created as a companion app for the companies neck cushion. While that is the case, it can be used without it free of charge and without restrictions.
After you have installed the application on your Android device and started it up, you can use swiping motions to the left or right to switch between the six sounds it makes available.
Six may not sound like much when other applications support dozens of sounds which you can mix to create even more, but sometimes, less is more.
When you switch to one of the sounds, available are waves, birds, fire, mountain stream, forest and running water, it starts to play automatically. You can leave the app or turn off the screen of the device and the sound will continue playing.
A tap on the screen stops playback, while a tap on the clock icon at the bottom will display a sleep timer that you can configure to stop playback after 30, 60 or 90 minutes.
The sound quality is good and there is not a clear distinguishable end of the loop which I consider important as it prevents me from relaxing.
The app is rather basic when it comes to the sounds it offers, and if you require more or different ones -- white noise, thunder or rain is missing for example -- then you should check out other apps such as the one linked above which deliver that.
MUJI To Sleep on the other hand offers six sounds of good quality and a nice interface that is easy to use.
