My new favourite app: F.Lux

Ever wake-up feeling unrested? Find it difficult to wind-down once you jump into bed? This could be due to over exposure to “blue light” of an evening. 

As soon as darkness falls, our body begins to produce melatonin, a hormone produced by lack of exposure to the sun or daylight that help us wind-down and fall asleep. Ever feel like you are ready to jump into bed earlier in the wintertime? This is melatonin working its magic. 

In the caveman era, this system worked really well. The sun would rise and fall and so would our melatonin secretions. Our sleep patterns were pretty much set in stone and as a result, we would wake feeling rested and ready to take-on the day. Today however, things are a little more complicated.

During the day, computer screens are designed to look like the sun. But, at 9PM, 10PM, or 3AM, you probably shouldn’t be looking at the sun. Computer screens emit bright, blue-ish lights that inhibit our natural secretion of melatonin and as such, we experience difficulty winding down and falling asleep. This then affects our quality of sleep and as such, our health later down the track. TV’s, tablets, phones and other electronic devices are all guilty of blue-light exposure.

Now before you turn away and tell me there is no way in this world you can give up your laptop late at night, I have some good news! There is an app that naturally changes the colour of your computer screen tablet or phone to the time of day. It’s called F.Lux. 

F.lux makes your computer screen look like the room you’re in, all the time. When the sun sets, it makes your computer look like your indoor lights. In the morning, it makes things look like sunlight again. All you have to do is select your preferred lighting, where you live (nearest capital city is fine) and f.lux will do the rest, automatically.

F.lux, has made such a difference to my late night computer sessions and having installed it on my phone, prevents me from being blinded by my phone during the early hours of the morning.
