The poll, which surveyed 1,500 people between the ages of 25 and 55 in the United States, United Kingdom, Canada, Germany, Mexico and Japan, found that the Japanese reported an average sleep time of only 6 hours and 22 minutes, while Americans averaged 6 hours and 31 minutes.
The average cycle is 1 hour and 30 minutes, however cycle length can vary from 60-120 mins. depending on the person. If we truly were to sleep without any disturbances and no alarm clocks, we would always wake up on a multiple of 90 minutes. For example after: 4.5 hours, 6 hours, or 9 hours of sleep. E.g., 5 complete sleep cycles = 90 mins + 90 mins. + 90 mins. + 90 mins + 90 mins = 7.5 hours of sleep.
