- Is a Good Night's Sleep Really Essential to Good Health?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: Although my wife and I have very different sleep habits we both
- seem to be doing fine. However she sleeps for eight to ten hours each night,
- and has a good sleep. I only sleep for about four hours, it seems. We would
- like to know if is it true that a good night's sleep is really essential to
- good health?

- ANSWER: A good night's sleep, one that is restful and calm, is high on the
- list of priorities of many readers, and so your question is an interesting
- one. More and more researchers are finding that a good night's sleep is
- actually very important in fighting disease. While there is a great variety
- in actual sleep requirements from individual to individual, most doctors feel
- 6 to 9 hours of total sleep in a 24-hour period is the proper amount for
- adults.
- Many aspects of sleep remain a mystery to researchers. Some even used to
- wonder if sleep was necessary at all. Recent research, however, has shown a
- link between sleep and the immune system. In experiments at the University of
- Chicago, white rats deprived of sleep died in an average of 19 days. During
- the deprivation period, the rats developed brown fur and ulcers of the paws
- and tail. In 1980, researchers John Pappenheimer, James Kreuger and Manfred
- Karnovsky isolated the chemical that induces sleep, muramyl peptide. This is
- a chemical known to activate cells called macrophages, which rush to sites of
- infection, where they remove bacteria and other foreign bodies from blood and
- tissues.
- Macrophages in turn make interleukin-1, a chemical which is known to
- influence temperature regulation and fever. Macrophages also signal to other
- disease fighting cells called lymphocytes, that they are needed at the site of
- an infection.
- Research into human sleep deprivation shows that it usually leads to
- irritability and fatigue, difficulty in concentrating and remembering, poor
- muscle coordination and visual or tactile hallucinations and illusions. Thus
- a bad night, with poor sleep patterns or little restful sleep, leads to a bad
- day, disrupting normal routines and reducing your efficiency.
- Scientists have also experimented with depriving people of one of the two
- states of sleep. They are known as REM sleep, or rapid eye movement sleep, in
- which dreaming occurs, and N-REM sleep, or nonrapid eye movement sleep. REM
- deprivation led to irritability, apathy, poor judgement, increased sensitivity
- to pain and a decrease in alertness.
- Many people who abuse sedatives, tranquilizers, antidepressants, and
- alcohol suffer many of the problems I've just mentioned, because these
- chemicals interfere with REM sleep.
- Most doctors agree that sleep helps people to recuperate from illness.
- It also has been theorized that REM sleep allows healing of mental activities
- and provides preparation for wakefulness.
- So, it seems that sleep is both a period of rest for the body and mind.
- There is still much more research necessary to unravel its many mysteries.
- Scientists hope to someday understand exactly how sleep works along with the
- immune system, and why sleep is part of the daily cycle of life. In your
- cases, since you state that you are both doing well, it is apparent that each
- of you is getting sufficient sleep, and so have little to worry about.
