You know how one of the advices for maintaining a healthy sleeping pattern is to stop using any sort of back-lit screens an hour or so before you go to bed? The idea behind this is that looking at a computer screen is looking directly at a light, tricking your body into believing it’s day. However, sometimes it isn’t that easy to stop using the computer. I tend to hang around on the computer until 22:00 and then go to bed at around 22:20. Luckily, I found out about F.Lux, which adjusts your screen to the time of day. At night, it removes the ‘blue glow’ from your screen, which removes the ‘daylight effect’, instead giving more of a ‘twilight effect’, which is supposed to help relieve the problems caused by screen usage at night. I’ve been using this tool for the past few weeks and I must say I’m pleased with it. It took a little getting used to, but I feel it’s worth it. Give it a shot for a couple of weeks and if you like it, keep it.
