Night Shift (software)

Do you know how you have a time when you go to sleep and a time when you wake up? Some people work at a different time called night shift. Night shift means they work when most people sleep.

Just like people, some computers and phones can also have a night shift mode. This means that the screen changes to a warmer color when it gets dark outside. You know how you have a night light in your room? It helps you see without hurting your eyes. Night shift is like a night light for your phone or computer.

When the screen is too bright at night, it can affect the way you fall asleep. The screen can keep your brain awake instead of letting it know it's time to sleep. So, night shift makes the screen warmer to help tell your brain it's time to sleep soon.

That's why when you put on night shift on your phone, your screen may look more yellow or orange. This is better for your eyes and helps you get a better night's sleep.
