How many minutes of REM sleep should you get a night?
On average you’ll go through 3-5 REM cycles per night, with each episode getting longer as the night progresses. The final one may last roughly an hour. For healthy adults, spending 20-25% of your time asleep in the REM stage is a good goal. If you get 7-8 hours of sleep, around 90 minutes of that should be REM.
How many REM cycles is good sleep?

Is it OK to sleep in increments?
Is biphasic sleep unhealthy?
