While the sun naturally emits blue light, too much artificial blue light from computers, laptops, phones, and other devices can cause sleep trouble, eye strain, and headaches. Here are a couple of ways to reduce discomfort.
To adjust color temperature and reduce blue light on your Windows devices, select Start > Settings > System > Display > Night Light Settings. Under the Schedule option, turn Night Light to On. Select your desired times or use the Sunset to Sunrise option.
To use Night Shift on Mac devices, go to System Preferences > Displays > Night Shift. Here, you can then select your color temperature and set a custom schedule.
Whether from the sun or a device, too much blue light in the evening will tell your body it’s still daytime. Dark Mode, Night Light, and Night Shift are all options to help with this. Adjusting your device to a warmer color hue a few hours before bed will help your body wind down for sleep.
