This option would only wake us up after we’ve had x amount of sleep cycles. Perfect for a daytime snooze without accidentally oversleeping and messing up our body clock. It would be alot better than setting our alarm at 90 minute intervals because for people like me it can take anywhere from 5 minutes to a couple hours to fall asleep.
