How to use the iOS Sleep focus mode in iOS 16

You can use the Health app in iOS 16 to help meet your sleep goals by scheduling regular times for going to bed and waking up. You can create multiple schedules.

For the sleep schedules you set, a Sleep Focus helps reduce distractions before and during bedtime. For example, it can filter out notifications and phone calls, and it can signal to others that you’re not available. You can also schedule a wind down period to begin from 15 minutes to 3 hours before your bedtime. Your Sleep Focus begins at the start of your wind down time.

To help you wake up on time, you can select an alarm sound, a vibration, and a snooze option. Or you can choose to have no alarm at all.

To set up a Sleep Focus:

1. Go to Settings > Focus, then tap Sleep.
   If you don’t see Sleep as an option, tap the “+” sign at the top right, tap Sleep, then tap Customize Focus.
2. Customize your focus.
   For example, you can allow interruptions from people important to you, customize the Lock Screen and Home Screen, and customize how apps and your iPhone behave when a Sleep Focus is on.

How to set up your first recurring sleep schedule:

When you set up a Sleep Focus, you can set your next bed and wake up times. This schedule repeats only once. To set up a recurring sleep schedule, do the following:

   • Set the alarm options: Turn Alarm on or off.
     When Alarm is turned on, you can choose a sound, its volume, a vibration, and the snooze option.

   When you tap Done, the changes apply to every day in the schedule.
