As you sleep on through the night, your REM phases grow longer in each sleep cycle. By morning, your fourth or fifth sleep cycle (ending when you wake up for the day) may allow for 45-60 minutes of uninterrupted REM sleep.
In adults, total sleep time, sleep efficiency, percentage of slow-wave sleep, and percentage of REM sleep significantly decrease with age, while light sleep and wake after sleep onset increased with age. The decline in deep sleep begins around age 36-50. However, it is important to note that these changes are less prominent among women and in the healthiest older adults. In summary, sleep duration as well as structure changes with age and reflects alterations in physiology and health.
