Twilight helps you sleep better by adjusting your melatonin levels [Freeware]

Recent research suggests that all this artificial light from our gadgets like tablets and smartphones could be disrupting our sleep patterns. Apparently the problem is that the light from these screens, especially when absorbed later in the evening or at night, can really upset our circadian rhythms and reduce our levels of melatonin.

Worse still, around 90% of us actually use a computer or electronic device in the hour before we go to bed, which makes the problem even more acute. Computer users have had the advantage of using the great f.lux freeware program for a while, but now there’s a solution on offer for Android tablet and phone users too.

Twilight adjusts the hue and intensity of your tablet or phone screen by filtering out the blue spectrum and introducing a warmer more red hue towards the evening. By mimicking the waning sun in this way, the app aims to reduce the effect of the artificial screen light on your melanopsin receptor in your eyes, thereby keeping your melatonin levels on a more even keel.

There’s tons of research listed on the app page relating to circadian rhythms and suchlike, but the real proof will be if you sleep better or not after installing this app. There is, of course, a school of thought that says it might be better to switch off your phone, computer or tablet altogether in the evening in order to give your brain a rest before bed, but that’s probably a bridge too far for most folk.
