Final answer:
In late adulthood, sleeping patterns often shift towards more frequent awakenings, earlier rising, prevalence of insomnia, earlier bedtimes, and a decrease in deep sleep.
Step-by-step explanation:
The sleeping patterns in late adulthood often include shifts where individuals wake more frequently at night, get up earlier, experience insomnia, and go to bed earlier. These changes in sleep patterns also show decreases in deep sleep. Throughout our lives, our sleep patterns change, and as we grow older, we tend to sleep less and have more fragmented sleep. This fragmentation is characterized by waking up more often during the night, having a harder time falling asleep, and experiencing a decrease in the proportion of deep NREM sleep (Non-Rapid Eye Movement), particularly stages 3 and 4, which are the most restorative stages of sleep.
