Discussion of underlying conditions of Insomnia:

Insomnia: NWHIC (Excerpt)

Chronic insomnia is more complex and often results from a combination of factors, including underlying physical or mental disorders. One of the most common causes of chronic insomnia is depression. Other underlying causes include arthritis, kidney disease, heart failure, asthma, sleep apnea, narcolepsy, restless legs syndrome, Parkinson's disease, and hyperthyroidism. However, chronic insomnia may also be due to behavioral factors, including the misuse of caffeine, alcohol, or other substances; disrupted sleep/wake cycles as may occur with shift work or other nighttime activity schedules; and chronic stress.

Insomnia: NWHIC (Excerpt)

Some behaviors may prolong existing insomnia, and they can also be responsible for causing the sleeping problem in the first place:

  • expecting to have difficulty sleeping and worrying about it

  • ingesting excessive amounts of caffeine

  • drinking alcohol before bedtime

  • smoking cigarettes before bedtime

  • excessive napping in the afternoon or evening

  • irregular or continually disrupted sleep/wake schedules

Stopping these behaviors may eliminate the insomnia altogether. (Source: excerpt from Insomnia: NWHIC)

A Good Night's Sleep -- Age Page -- Health Information: NIA (Excerpt)

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.
