Lately I’ve been getting quite proactive about my health. In doing so, I stumbled across something that’s all the rage, these days:
Okay, so we’ve had blue light for a while now, but, as technology becomes more apparent, and many of us humans get further glued to the many screens at our disposal, it’s become apparent that this blue light is a problem.
Assuming I’m understanding the science behind it, when we’re exposed to blue light, it typically suppresses the secretion of the hormone melatonin, which is responsible for helping us to sleep at night. It’s a natural occurrence, as the sun itself produces blue light which of course helps keep us awake during the day.
If you’re like me, you’re on the computer late at night, then go to bed and stare at your phone for a little while, only to wake up and do it all over again! This can mess with our circadian rhythm.
Well, aside from switching off your screens, you can install something like the small, free program called f.lux on the PC, or a similar app for your mobile phone. I’ve been trying f.lux tonight and have found it to be very nice on the eyes, although a little strange at first. I’m getting used to it. I don’t feel as alert as I usually would around this time, and it’s only just gone 9pm! I’m usually up at around 4-5am before I go to sleep, these days.
So, I’d recommend giving it a go. You can also lower your display brightness in general, and use dim red lights to help. I’ve even read some comments online that those struggling with insomnia have noticed a big difference using software that reduces blue light.
