iPhone features that could improve your sleep overnight

The article lists seven built-in iPhone features — including the Health app, Wind Down, Sleep Focus, Sleep Schedule, App Limits, Downtime and Night Shift — that can monitor rest and limit nighttime disruptions.

Smartphones are often blamed for disrupting sleep because of late-night scrolling and notifications. The iPhone includes several built-in features that can instead help monitor rest and create a bedtime routine. The article highlights seven of these features. They range from tracking tools in the Health app to display and notification settings designed to limit nighttime interruptions. Notable iPhone sleep features: - Health app: Compiles data from connected wearables and tracks metrics such as time asleep, blood oxygen, wrist temperature, heart rate and sleeping respiratory rate, with interactive charts. - Wind Down: Available on iOS 15; lets users set a wind-down period of 15 minutes to three hours and can enable Do Not Disturb during that time. - Sleep Focus: Available on iOS 16; automatically enables a chosen Do Not Disturb period, shows a simplified lock screen, and permits selected calls or apps to bypass restrictions. - Sleep Schedule: Encourages setting regular bedtime and wake-up times and provides reminders to support a consistent routine. - App Limits and Downtime: Managed via Screen Time; App Limits sets daily usage caps for specific apps, while Downtime restricts access and notifications during designated periods. - Night Shift: Adjusts the display to warmer tones around sunset to reduce blue light exposure; the setting is found in Display & Brightness. Summary: These built-in options are described as ways to reduce nighttime interruptions and to collect sleep-related data when paired with wearables. Their practical effect depends on individual settings and usage patterns. Undetermined at this time.
