Frequently Asked Questions
How do sleep cycles work?
The average human sleep cycle is about 90 minutes. Waking up at the end of a cycle, rather than in the middle of one, helps you feel more refreshed.
What is the 14-15 minute rule?
Most people take about 14-15 minutes to fall asleep once they hit the pillow. Our calculator includes this buffer in its suggestions.
