But let me talk a little bit about the importance of sleep
我想简单讲讲睡眠的重要性
though I don't need to convince most of the people here
尽管我不需要给大家灌输这个概念
Sleep is a lot like a diet
睡眠就像饮食一样
It represents a biological imperative
是一种生理必然活动
that's based on both quantity and quality
由数量和质量来决定
so we need a certain amount and certain quality
所以我们需要一定数量和质量的睡眠
We meet those needs by engaging in behaviors
我们通过行为活动来保证这一点
And these behaviors are largely driven
而我们的行为则受到
by genetics and intrapersonal factors
基因和人际因素的驱动
so for example
例如
if you...we took sleep diaries of everyone in this room
如果我们对在座各位的睡眠情况做一个每日记录
they would not be randomly distributed across the day
那么你们的睡眠不是在一天当中平均分布的
There is a reason that we sleep at night
我们夜晚睡觉是有原因的
and a lot of those are biological
大多数原因是生理上的原因
But the behaviors that we engage in
但我们为满足这些生理需求
to meet these biological needs are socially constructed
而实施的行为则是社会构建的
influenced by the environment
受到环境的影响
and dictated by societal norms
由社会规范来决定
That becomes very important
当我们谈论保证睡眠质量
when we are talking about differences in sleep attainment
对健康有重要的影响时
being important for health
这一观点显得非常的重要
