Sleep cycles typically last around 90 minutes, but they can vary from person to person. The goal is to wake up at the end of a cycle rather than in the middle, which can help you feel more refreshed. However, sleep quality depends on many factors, including lifestyle, stress, and overall health. While this calculator provides a general guideline, your ideal sleep schedule may differ.
