Sleep and Aging

There are two kinds of sleep in a normal sleep cycle - rapid eye movement or dreaming sleep (REM) and quiet sleep (non-REM).

Everyone has about four or five cycles of REM and non-REM sleep a night. For older people, the amount of time spent in the deepest stages of non-REM sleep decreases. This may explain why older people are thought of as light sleepers. Although the amount of sleep each person needs varies widely, the average range is between 7 and 8 hours a night. As we age, the amount of sleep we can expect to get at any one time drops off. By age 75, for many reasons, some people may find they are waking up several times each night. But, no matter what your age, talk to a doctor if your sleep patterns change.

Common Sleep Problems

At any age, insomnia is the most common sleep complaint.

Insomnia means:

Taking a long time to fall asleep (more than 30 to 45 minutes) Waking up many times each night Waking up early and being unable to get back to sleep Waking up feeling tired With rare exceptions, insomnia is a symptom of a problem, not the problem itself.Insomnia can be linked with other sleep disorders such as sleep apnea, a common problem that causes breathing to stop for periods of up to 2 minutes, many times each night.

There are two kinds of sleep apnea: Obstructive sleep apnea is an involuntary pause in breathing - air cannot flow in or out of the person's nose or mouth. Central sleep apnea is less common and occurs when the brain doesn't send the right signals to start the breathing muscles. In either case, the sleeper is totally unaware of his or her struggle to breathe. Daytime sleepiness coupled with loud snoring at night are clues that you may have sleep apnea.
