In my training, I was taught that older adults, in general, go to bed early, get up early, and have poorer sleep overall than younger adults. This article discusses new research about the sleep habits of older Americans. Researchers did telephone surveys and found that many of the respondents had sleep schedules and sleep quality similar to those of younger adults.
These results are not actually surprised, as recent studies have shown similar results and Dr. Ancoli-Israel has lectured about this recently. It is true that some sleep disorders are more prevalent as we age, but getting older does not automatically mean you are destined for poor sleep.
