Think UV rays are the only kind of light you need to worry about? Think again.
Even if you’ve slipped, slopped, and slapped, you might still be at risk of harm from another type of light: blue light.
From smart watches and phones to tablets and desktop computers, all digital devices emit blue light. Like natural blue light, which combines with other colours to create sunlight, artificial blue light tells your brain that it’s daytime (a.k.a. time to be awake) — no matter what time of day it is.
If you’re anything like us, chances are you spend 8 hours a day on a computer before winding down by checking social media, the news, and messages on your phone. By the end of the day this can all add up to some serious blue light exposure, and can make it hard to fall into a deep sleep.
