🛌 Expert Tips: Better Sleep with Smart Alarms

Sleep experts recommend waking at the end of a sleep cycle, typically 90 minutes. Combine our alarm clock with the Sleep Calculator Tool to plan your bedtime and wake-up time effectively.

Best practices:

  • Avoid snooze. It disrupts REM sleep.

  • Use light or music-based alarms instead of harsh sounds.

  • Set your alarm 90 minutes before your final sleep cycle ends.

  • Combine with blackout curtains and a consistent sleep schedule.
