Sleep Cycle & Wake Timer
Calculate the best times to wake up to feel refreshed by aligning with 90-minute sleep cycles.
Sleep occurs in cycles of approximately 90 minutes. Waking up at the end of a cycle, rather than in the middle of deep sleep, helps reduce grogginess and improves morning alertness.
Prioritizing 5 to 6 full cycles per night is essential for cognitive health, muscle repair, and hormonal balance. Use this tool to plan your rest for better performance and long-term health.
