If you find yourself constantly asking, “What time should I wake up to feel refreshed?”, you aren’t alone. The secret isn’t just about climbing into bed early—it’s about timing your sleep schedules so that your alarm goes off at the end of a natural 90-minute sleep cycle. By combining these cycles with the average 14 minutes it takes a person to fall asleep, you can build a perfect nightly routine.
