Aging and Sleep - Symptoms


If you are getting healthy sleep on a regular basis, you should feel alert during waking hours. One of the main symptoms of all sleep problems is daytime sleepiness. Sometimes sleepiness will manifest in other ways,  such as loss of memory or concentration problems. You may also feel irritable, depressed or a bit confused when you're sleep deprived.
