Go to bed at the right time and wake up between your natural 90-minute sleep cycles to feel rested and refreshed. A good night's sleep consists of 3 to 6 complete cycles. ◦ Calculate your best bedtime ◦ Calculate your best wake-up time ◦ Select when you want to wake up ◦ Relaxing sounds and sleep meditation to help you fall asleep faster. The average person takes about 15 minutes to fall asleep. If you wake up at one of the calculated times, you'll wake up between 90-minute sleep cycles. The Sleep Calculator app helps you decide when to go to sleep so you can wake up at a specific time and ensure a good night's rest, or what time you should wake up if you want to go to sleep right now.
