Your body has an internal clock for keeping time called the circadian system. It takes cues from your surroundings and sends signals to your body throughout the day to regulate things such as sleep and alertness. Studies have shown that the absence of blue light signals your body; it’s time for bed.
Apple devices have a feature called Night Shift that’s similar to the Night Light feature on Windows 10. Night Shift adjusts the colors of your screen to show warmer colors and less blue light. This post shows you how to manage Night Shift on macOS 10.15 Catalina, iPhone iOS 13, and iPad iPadOS 13.
