Here’s a really good thing, for pretty much anyone who finds themselves regularly staring at a screen (laptop, TV, tablet, phone etc.) into the evening hours: an app called F.lux that modulates the color spectrum emitted from your screen, in a way that synchronizes itself with the rising and setting of the sun.
The basic idea is that the white-blue light typically emitted from our screen sends our nervous and endocrine systems the message that it’s daytime — and hence, not time for sleep. And during the day, this is all good and fine. But not surprisingly, we often find it challenging falling asleep directly after working at our computer, or watching a movie, or cruising our social network accounts, late at night. This is because our computer-programmed endocrine system still believes it’s high noon.
The F.lux app considers your geographical location, as well as your typical wake-up time and bed-time, and adjusts the color temperature accordingly. I just went for its default settings — and noticed a difference on the very first night. Anyway, if you haven’t already discovered this, it’s definitely worth checking out.
