What is blue light and why is it bad?

There are plenty of good lifestyle websites on the internet where you can read almost without exception that we no longer use our electronic devices, such as phones, tablets, computers, and TVs, at least 1 hour before bedtime because their light degrades the quality of our sleep. The latter statement is true because the electromagnetic wave spectrum (or color spectrum) emitted by screens is very similar to that emitted by the sun, so to put it very simply, our brain thinks it is still in the sun.

This is a problem because the biochemical processes that precede sleep, which prepare for sleep at night, and the drowsiness that precedes it, do not start properly in the evening. However, you should not avoid using these tools because, as I wrote in the introduction, there are applications that

Up for the night!

On modern monitors, we can usually adjust the intensity of the blue (and red and green) light in the settings, but this is usually not possible on phones. On iOS, there is a solution built into the operating system (Night Shift), but there are also a lot of apps for Android for this purpose. Based on my experiments so far, the app called Night Mode is the best possible choice. Once started, it explains why it will be very good for us to use it (which I have briefly summarized above) and then suggests that you set it up to add it to your protected applications.

This is important to keep it running and not close it after turning off the screen, for example. Otherwise, the application is extremely easy to use. You can set the color temperature (you should choose the lowest possible one), or its intensity, plus you can take the brightness of your phone below the minimum. By the way, the latter function also completely replaces the application presented in the following article, also called Night Mode.

Errors and other features

Night Mode also allows you to set a timer to let you know how long the app will run, but of course, you can turn it on and off manually as you like. If enabled, the notification bar will have a permanent notification from which you can access the program at lightning speed.

However, in addition to the many positive features, Night Mode also has some flaws. Since it’s just an app, both the notification bar and the software buttons work independently of it, as do the Facebook Messenger chat heads, so they don’t affect their brightness or color temperature.

Summary

Aside from a few shortcomings that may not be feasible anyway, Night Mode is a very useful application. It may be weird at first that every color has a reddish tinge, but it’s really worth getting used to for those few hours of the evening, especially knowing how much it will help our sleep and thus contribute to our health.
