YUMI SLEEP CALCULATOR
Our recent independent research found that just 15% of people wake up feeling well rested so we’ve created this sleep calculator which will suggest the best time for you to go to bed, by maximizing your full sleep cycles.
Sleep consists of 90-minutes-long sequences, repeated throughout the night. You'll wake up feeling better if you wake up at the end of a cycle, rather than in the middle of it, so use this calculator to find out what time you should go to sleep if you want to wake up feeling more refreshed.
Simply enter what time you want to wake up and our calculator will find the best bedtime for you. Alternatively, if you want to go to bed now, it will tell you what time to wake up.
