Insomnia, the most common sleep complaint, is the feeling of not having slept well or long enough. Common problems are sleeping too little, difficulty falling asleep (taking more than 30-45 minutes), awakening frequently during the night, or waking up early and being unable to get back to sleep. Age-related changes contribute to one's ability to sleep continuously and soundly. Many older adults have problems sleeping. With advancing age, some people switch to shorter nights and some to longer ones. 6 pgs. Bibliography lists 4 sources.
