How does blue light affect your sleep?

In the age of technology, we have access to all the information we need right at our fingertips. At night time, however, our tech can do us more harm than good. Blue light, the kind found in phones and laptop screens, has been shown to disrupt the circadian rhythm and keep us alert and awake when we really need to rest. Of course, the easiest way to avoid blue light exposure at bedtime is to stop using your screens in bed - but that's not always as easy as it sounds. It's often all too tempting to let your sleepy brain start thinking about bizarre questions you need to answer right this second, or remember that really important email you had to send earlier. One simple trick is to put your phone on charge away from the bed, so that you can't possibly reach it when you're meant to be getting some shut-eye. You could even put it under your bed so that it's within reach in an emergency but not the last thing you see when you turn out the light. Unfortunately, blue light can cause sleeping problems even before you try to settle down for the night. Studies show that blue light can affect your sleep up to three hours before bedtime. It's not a lost cause though, and you don't have to go back to the dark ages as soon as the sun goes down. Programs like f.lux for PC and Red Moon or Twilight for android phones adjust the levels of red and blue light in your screen depending on the time of day. It's a great solution for people who find themselves working - or playing - at all hours. Other ways to eliminate blue light from your sleeping quarters might include investing in smart bulbs, which you can customise to show only yellow or even entirely red light at night - perfect for us scaredy cats who like to leave a light on! In the same vein, avoid LED lights, which emit white light. If you're totally unable to remove LED lights from your room, try using a lampshade that tones down the amount of blue light. If you eliminate blue light from your pre-sleep ritual and are still having difficulty dropping off, perhaps you need a new mattress.
