If you have different arrangements, you may also choose one of the following times:
--
(7 sleep cycles)
--
(4 sleep cycles)
--
(3 sleep cycles)
--
(2 sleep cycles)
--
(1 sleep cycles)
If you wake up at one of the above times, you will get up in between the 90-minute sleep cycles, assuming it takes you
15 minutes to fall asleep. It is recommended to have 5-6 complete cycles of sleep every night.
