there is a blue light filter button,
apparently the night-mode, which is a smartphone feature that shifts the colors of
your screen from cold to warm tones, aiming to make you sleep better, but before using it, perhaps you should read this study led by Dr. Tim Brown which suggest that relying on your phone’s
night mode to help you sleep wouldn’t work. Blue light actually don’t disrupt
sleep, contrary to popular belief. In fact, your phone’s yellow lights during
night mode is actually worse, according to the study. The Guardian has the details:
According to the study, brightness levels are more important
than colour when it comes to stimulating the body clock. However, when the
light is equally dim, blue is more relaxing than yellow.
This makes basic sense: daylight is yellow, twilight is
blue, and sunrise and sunset are pretty reliable ways to tell your body clock
what time it is. Of course, at this point, we only know it works on mice – and
mice don’t have phones. “We think there is good reason to believe it’s also
true in humans,” says Dr Brown.
There is perhaps a more obvious truth to be drawn – if your
phone is telling you to switch to night mode, it is time to put down your
phone.
It is not the colour of the screen that is keeping you
awake; it is all the stuff your phone offers as an alternative to sleep at 2am.
There is only one real night-mode switch: the off button.
so there you have it, although I have to say sleeping has never been a problem for myself, as soon as my head hits the pillow I am awake as the alarm goes off, but is it not strange the number of times that something is supposed to be good for us turns out to be bad, and vice versa?
