Microsoft to include blue light filter in Windows 10 for better sleep

Microsoft has secretly added functionality to reduce blue light emitted by displays in the latest Windows 10 Insider build. Reducing blue light should make sure users sleep better after using their electronics devices in the evening or night.

That is possible because blue light affects levels of the sleep-inducing hormone melatonin. Exposure to blue light in the evening causes people to be sleepier the next day and they need more time to wake up. Therefore blue light filters have become popular, e.g on Android and iOS there are apps such as F.lux (also available for Windows) and Twilight that reduce the emitted blue light.

Twitter user Core discovered a reference to “Windows.Data.BlueLightReduction” in the latest Windows 10 Insider build and found that the feature will have a Quick Action toggle. The setting allows users to set the color temperature in Kelvin and can be automatically set based on sunrise and sunset. Core was able to enable the Quick Action toggle on his system already as shown in the last Tweet below.
