How to Enable Night Light in Windows 10

The LED screens of your desktop and notebook computers, tablets or smartphones emit blue light which affects the release of melatonin in the brain. Melatonin is a hormone released by the pineal gland located inside the brain and regulated the sleep cycles for human beings. Staring at your computer screens results in a deficiency of the melatonin and a lack of melatonin can disrupt the normal sleep cycles. This is why I have been using the f.lux software that slowly changes the screen color to display warmer and warmer screen colors as the Sun sets and night falls.

But now Microsoft has added the same feature in Windows 10 itself. The new version of Windows 10 Creators Update comes with the Night Light feature. This feature simulates dimmer and warmer colors in Windows 10 as the Sun sets in order to give you better sleep later. Here is how you can enable this:

  1. Click on the Start menu icon in the lower left corner of Windows desktop. Select the cogwheel icon to open Windows Settings.
  2. In the Settings window, select System and then Display. You would see Night Light options on the right side. Click on the small flip button to enable the Night Light.Windows 10 Night Light
  3. If you click on the Night light settings, then you can change the various settings related to night light. You can turn it off, change the screen color temperature and schedule it to automatically turn on and off at specified times.Windows 10 Night Light

If your Windows PC is not displaying the night light option, then you either have not installed the latest version of the Windows 10 operating system or you have to update the graphics drivers for your PC.  After enabling the night light mode, the screen will start to become dim because warmer colors will be displayed. As soon as the Sun goes down, the screen will slowly become dimmer and dimmer. That might not look nice, but it should actually give you a better and healthier sleep.
