Formula:
The REM sleep calculator works by estimating standard 90-minute sleep cycles. To feel refreshed, it's best to wake up at the end of a full cycle. The calculation involves subtracting typical sleep cycle durations (multiples of 90 minutes) from your desired wake-up time, accounting for an average 15 minutes to fall asleep. This helps you hit the sweet spot for awakening between sleep cycles.
