Sleep Cycle Calculator – Wake Up Refreshed & Energized
Optimize your sleep with the Sleep Cycle Calculator, a tool designed to help you wake up feeling refreshed by aligning your bedtime or wake-up time with your natural sleep cycles.
How It Works
Sleep occurs in 90-minute cycles (adjustable in settings), moving through light, deep, and REM sleep. Waking up at the end of a cycle—rather than in the middle of deep sleep—helps you feel more alert and well-rested.
Features
✔ Two Calculation Modes:
- “Wake Up At” – Find the best bedtime to wake up at your desired time.
- “Go to Bed At” – Determine ideal wake-up times based on when you fall asleep.
✔ Customizable Settings:
- Adjust sleep cycle length (default: 90 mins)
- Set time to fall asleep (default: 14 mins)
✔ Smart Recommendations:
- Shows multiple options (1-6 sleep cycles)
- Highlights optimal times for 4-6 full cycles (6-9 hours of sleep)
