我們需要多少睡眠
[ 2007-12-25 11:30 ]

睡眠與食物和水一樣,對我們的精神健康和身體健康至關重要。如果不睡覺,人就會像喝醉酒一樣,頭重腳輕、反應遲鈍、手眼不協調,決策困難、判斷失誤,甚至連講話都理不清思路。占據我們生命1/3時間的睡眠對精神、情感、身體健康、免疫力的提高和人體細胞生長、修復起著重要的作用,睡眠時大腦細胞完全休息,大腦功能得到充分保養和恢復。那么,我們到底需要多少睡眠呢?是不是睡得越長越好呢?這篇文章將給您解答這些問題。

The amount of sleep an individual requires varies from person to person, but most adults average eight hours of sleep.

Sleep plays a vital role in our dailyregimen, as during this dormant period, it recharges andrejuvenatesweary body organs and tissues, and restores the body to an alert state. A person's lifestyle is another variable in the amount of time he needs to achieve this healthy balance, and to feel well rested upon awakening.

The quality of a person's sleep also factors into the sleep equation. When we drift off to sleep, we either fall into a deep, restful sleep, or into a shallow, light sleep. One who normally requires eight hours of sleep, but sleeps shallowly, will most likely awaken feeling tired. In contrast, if the same individual sleeps fewer hours, but lapses into a state of deep sleep, he may well awaken refreshed andinvigorated.

A lucky few can bypass shallow sleep altogether, and fall directly into deep sleep on an as needed basis. Alexander the Great's militaryprowessmay have been due, in part, to his ability to take a "cat nap."

Yet one more variable factors into the amount of sleep we require: that of the brain and of the body sleeping simultaneously. Under normal circumstances, the brain's sleep center blocks off the nerves to the brain and to the body to make sleep possible. The brain has no interest in doing anything, and could not even if it did, because the sleep center has shut down the internal organs, the arms, and the legs. Sometimes, however, the sleep center is unsuccessful in shutting down both the brain and the body at the same time. For example, in times of war, it is not unusual for soldiers suffering from sleepdeprivationand from combat fatigue to continue to march, despite the fact that their brains have halted. Thankfully, such a situation is ananomaly, and does not occur with great frequency.
