How can Windows 10 help me reduce blue light and allow me to sleep better?

Question

New research adds to this already large body of evidence of the power of blue light to interfere with sleep. The study of healthy young adults found exposure to blue light from computer screens between the hours of 9-11 p.m.:

1. shortened their total sleep time

2. significantly suppressed melatonin production

3. diminished sleep quality, by increasing the frequency of nighttime awakenings

Answer 1

Turn on Night Light.

A Windows 10 feature called Night Light that removes all the blue light from your screen. That is a big reason behind why we remain awake late at night. If you work on your computer in the night and don’t want it to affect your sleeping habits, you need to turn this feature on.

You can either manually enable this feature whenever you want. Or you can schedule Night Light which will enable this feature at a specific time of day.

To enable Night Light, go to Settings -> System -> Display, and turn on the toggle next to Night Light. You can also configure the intensity of Night Light and schedule its time by clicking on the “Night light settings” option marked in the picture below.

Answer 2

Actually, newer research shows that warm hues from displays can be worse than blue light.
