It controls when you feel tired or how you sleep. Your body clock controls circadian rhythm, which has been shown to be key to a number of health conditions.

It then uses that information to set the color temperature of your display - colder during the daytime and warmer in the evening. Night Shift doesn’t need a separate app, it is a feature of macOS that uses your Mac’s clock and your geographic location to determine whether it’s day or night where you are. As you would expect, you can control when and if Night Shift is invoked.

The blue-ish light emitted by most computer and mobile device displays can cause tired eyes to struggle at night, and it fools our brain into thinking it’s daytime, even when it’s late at night. While eye damage is unlikely and eye strain somewhat contentious there’s much more research that shows the effect of certain colors of light on our brains at different times of the day. One of the downsides of using a computer, or any device with a screen, is the effect it can have on both our eyes and our circadian rhythms. But to help you do it all by yourself, we’ve gathered our best ideas and solutions below.įeatures described in this article refer to the MacPaw site version of CleanMyMac X.
