Have you noticed that you don't go to sleep as easily as you used to? There could be any number of reasons, but a big one is likely the gadgets in your life.
Computer, smartphone and tablet screens are bright and they put out a lot of blue light. That blue light can trick your body into thinking it's daytime. If you're staring hard at a screen just before you hit the hay, your body is going to take a while to get back into nighttime mode. Fortunately, there's a solution.
If blue light is the problem, then it stands to reason that getting rid of the blue light would let you use your gadgets without confusing your body. And there are programs that do just that, such as the excellent F.lux for computers.
However, Android has similar apps, such as Lux and Twilight. These automatically shift your screen to a reddish tint, which mimics more closely the sunset and typical indoor lighting. That helps your body stay on a normal sleep cycle.
Lux is a general brightness and screen tool, while Twilight is programmed specifically for this task. Both have free options, so give them a try and see which on you like better.
