Why use the Night Shift feature?

Blue light emitted by screens can interfere with your circadian rhythm, making it harder to fall asleep and stay asleep. Night Shift reduces the amount of blue light emitted by your Apple Watch’s screen, promoting better sleep and reducing eye strain during nighttime usage.

Enabling Night Shift with Siri

Activating the Night Shift on your Apple Watch is simple with Siri. Here’s a step-by-step guide:

  1. Wake Siri: Raise your wrist to wake your Apple Watch and say “Hey Siri” or press and hold the Digital Crown until Siri activates.
  2. Give the command: Say “Turn on the Night Shift.”

Your Apple Watch screen will immediately adjust to a warmer color temperature, reducing blue light exposure.

Customizing Night Shift

For more control over when Night Shift activates, you can customize its schedule through your paired iPhone. Here’s how:

  1. Open Settings: On your iPhone, go to Settings.
  2. Select Display & Brightness: Scroll down and tap on Display & Brightness.
  3. Adjust Night Shift settings: Tap on Night Shift. Here, you can schedule when Night Shift turns on and off automatically, either by choosing Sunset to Sunrise or setting a custom time.

This customization ensures that the Night Shift aligns with your daily routine, automatically reducing blue light exposure at times that suit you best.

Manually controlling the Night Shift from the Apple Watch

In addition to using Siri, you can manually control Night Shift from the Control Center on your Apple Watch:

  1. Access Control Center: Swipe up from the bottom of the watch face to open the Control Center.
  2. Toggle Night Shift: Look for the Night Shift icon and tap it to enable or disable the feature.


With the ability to enable Night Shift through Siri, Apple has made it incredibly convenient to take care of your eyes and improve your sleep quality. Whether you use Siri or manually control Night Shift through the Control Center, this feature is a valuable addition to your Apple Watch’s capabilities.
