The iPhone is known for its built-in features that can help you get better sleep and ensure you wake up feeling refreshed. The Health app, which compiles health data from fitness trackers, watches, and other devices and apps, can provide insights into your health and wellness. The Apple Watch tracks sleep metrics such as time asleep, blood oxygen levels, wrist temperature, heart rate and sleeping respiratory rate. The iPhone's Sleep Schedule feature encourages users to set a regular bedtime and wake-up time, aligns with the user's body clock and optimizes sleep quality. The Sleep Focus feature enables an uninterrupted sleep every night, and the Wind Down feature allows users to customize a bedtime routine. The Night Shift feature helps reduce the impact of blue light on sleep and adjusts the phone's display to a warmer tone at sunset, making it easier on your device's eyes and reducing disruptions to the body's natural sleep cycle. These features can also help users maintain a consistent sleep routine and promote healthy sleep habits for overall well-being.
