Set up your first sleep schedule in Health on iPod touch

You can use the Health app to schedule a time for unwinding at the end of your day, getting to bed, and waking up.

Tap Browse at the bottom right, then tap Sleep.
Swipe up, then tap Get Started (below Set Up Sleep).
Follow the onscreen instructions.

After you set up your first sleep schedule, you can set additional schedules—for example, one for weekdays and another for weekends. You can also modify, turn off, or remove any schedule you create.
