At work, it’s important to feel energised and healthy to be as productive as possible. Nowadays, there’s a lot of talk surrounding blue light and the effects it has on the body. There are multiple ways you may feel the symptoms caused by blue light, not only do you have to worry about it while you’re at work but also in your personal time so it doesn’t affect your sleep patterns at night.

You may already be aware of the effects that blue light has on your body. Some symptoms you can feel from extended exposure to blue light while you’re working during the day include headaches, neck and back pain, eye strain, and blurred vision.

You can try the f.lux app on your computer or phone to transition the colours on your screen from cooler to warmer; the warm light will cause less strain on the eyes. Give your eyes a break frequently throughout the day to avoid headaches and blurry, dry eyes. Take short breaks from your computer often, looking away from any screens multiple times in an hour, or even going into a darker room to give your eyes a rest can help.

While you’re at work, it’s important to be aware of how much blue light you’re being exposed to.
