We’re told regularly these days that technology, particularly smartphones and tablets, are bad for our sleeping patterns due to the blue light that emanates from our devices. According to many experts, exposure to this blue light affects both the quality and quantity of our sleep. This is because the light effectively tricks our brains into thinking it’s still daytime and suppresses the production of melatonin, a hormone that prepares the body for sleep.
Luckily, if you have a Samsung phone, you can make use of their helpful blue light filter. The filter reduces the harsh light that is normally on the phone, so you can sleep easier. There’s even an option to gradually shift your screen to warmer colours before bedtime. It doesn’t turn on automatically, but it’s really easy to set up.
How do I do this?
If you have a Samsung phone, you can enable the blue light filter by going to Settings > Display > Blue light filter.
If your phone doesn’t have this feature but you like the idea of reducing your phone’s blue light and improving your sleep, you can download an app such as Twilight, which produces a similar effect on your screen. Twilight is available for free on the Google Play Store.
