What Sleep Quality Means
Quality is more than hours. How quickly you fall asleep, how often you wake, and how rested you feel all shape a good night.
Bedtimes fall into step with your natural sleep cycles.
This tool blends those factors into a simple score, inspired by the Pittsburgh Sleep Quality Index.
Use it to spot patterns and track changes as you improve your habits.
